A DEVICE FOR MIXING FLUX AND DROSS IN GALVANIZING ZINC POT
FIELD OF THE INVENTION
The present invention relates to a device for proper mixing of flux powder with dross in zinc melt in the galvanizing zinc pot comprising a table to hold two steel pipes; one jack; four wheels; a reversible motor attached with two pulleys; a reversible switch and a stainless steel cylinder with both ends open, having a stirrer attached with pulley. In particular, the present invention is directed to the mixing process, which enhances the surface reaction between exothermic flux powders and dross. Due to exothermic reaction the zinc is reversed back to liquid zinc. The entrapped zinc is removed from dross due to proper mixing and heat. BACKGROUND OF THE INVENTION
Galvanizing applies a zinc coating to a variety of steel products to protect against corrosion. The galvanizing of metallurgical products, such as steel strips, is carried out by stripping these products, which are stationary or moving, to dwell in a bath of molten metal, which is based on zinc and which can also contain variable quantities (up to a few %) of aluminum, lead etc. When they are for treating metallurgical products, these baths rapidly become supersaturated with iron, and Fe-Zn or Fe~AI-Zn intermetallic compounds precipitate. These precipitates are called "dross" and float either toward the surface of the bath (from which they are periodically removed manually) or toward the bottom of the galvanizing tank, depending on their density relative to that of the bath of zinc alloy. This density is governed by their composition; the Fe-AI—Zn dross float toward the surface and the Fe—Zn dross toward the bottom. The bath therefore permanently contains a relatively large quantity of dross.
The solubility of iron in molten zinc is generally a linear function of the temperature. At normal galvanizing temperature of approximately 455 C, the iron content is about 0.040%, while at a temperature of about 440 C. the iron content is about 0.015%. To improve the quality of a hot-dip galvanized thin steel sheet,

3
dross, such as Fe—Al—Zn precipitates (slag particles), on the zinc coating must be avoided. These particles are a combination of bottom dross and top dross.
These particles are discussed in greater detail in the publication by Kato et al., entitled Dross Formation and Flow Phenomenon in Molten Zinc Bath, Galvatech 95 conference proceedings, Chicago, 1995, pages 801-806. This publication is incorporated herein by reference as background material elaborating upon the nature of the types of dross particles that are formed in the environment in which the present invention operates.
Further in galvanizing line, steel strip at temperature higher than zinc melt continuously passes through zinc melt. At exit point the air knife are used to reduce the excessive zinc for attaining the certain required thickness. Due to air pressure the zinc particles fly near the bath and forms dross.
The consequence of this is that the dross is deposited, at the same time as the zinc alloy, onto the product to be coated and often causes serious surface appearance defects to appear in the coating without attaining the required thickness of the strips.
The dross-pick up on the strip during the hot-dip coating process due to the suspended dross in the bath is a major problem with the galvanizing operation. The presence of dross particles of Fe-Zn and Fe-AI intermetallics within coating is of particular concern when the steel strips are required in appliance of end-user areas.
The prior art document KR100312127 describes an apparatus and a method for recovering zinc from dross generated from a galvanizing bath which are capable of recovering pure zinc in the process of removing the zinc dross in case that zinc dross generated in zinc of the galvanizing bath of a hot dip coating facility during galvanizing is floated. The method for recovering zinc from dross generated from a galvanizing bath comprises a dross collection step of collecting floating dross of the galvanizing bath into an agitator through an injection port using a pusher moved back and forth by an air cylinder; a chemical reaction step of transforming the reactants into pure zinc and ash by chemically reaction of the dross with the flux in the agitator using vertical agitation movement of an impeller

4
after injecting flux from a flux box into the dross in the agitator that is collected in the dross collection step, and sucking a gas generated from the chemical reaction into an exhaust port so that the gas is exhausted into the atmosphere through an exhaust pipe in the state that the gas is cooled by cooling water; and an ash removal step of removing ash of the agitator generated in the chemical reaction step with a bucket so that the ash is discarded into a box.
Another prior art document KR20030095008 discloses a recovery apparatus with superior zinc recovery ratio which is provided to completely separate zinc contained in dross so that dross is removed by separating dross from zinc using chemical solvent, agitating propeller and nitrogen gas. The recovery apparatus with superior zinc recovery ratio comprises a guide rail arranged on an upper part of zinc pot; a shovel travel block and an injection unit travel block installed in such a way that they are individually driven and moved along the guide rail; a supporting plate installed at a lower part of the shovel transfer block in such a way that the supporting plate is ascended and descended; a shovel foldably connected to the supporting plate; a chemical tank resting plate installed at a lower part of the injection unit travel block in such a way that the chemical tank resting plate is ascended and descended; a chemical tank fixed to the chemical tank resting plate and installed in such a way that the chemical tank contains solvent and selectively injects the solvent to a lower side; and a reaction vessel which is arranged in such a way that the reaction vessel is dipped into zinc pot directly under the chemical tank and installed in such a way that the reaction vessel is moved back and forth along the reaction vessel supporting rail arranged on an upper part of the zinc pot, and in which the shovel is movably arranged.
The document JP2006111944 provides a device for recovering zinc from hot dip galvanizing bath floating dross capable of efficiently recovering molten zinc contained in floating dross scooped from the surface of a hot dip galvanizing bath, and preventing degradation of a yield of zinc. A dross storage container having a large number of openings in a bottom surface and a side surface is mounted on a tip of an arm of a dross-scooping robot installed in a vicinity of a

5
hot dip galvanizing bath, and floating dross is scooped thereby. A pressing means is installed above the hot dip galvanizing bath, dross inside the dross storage container is pressed by a die to squeeze out molten zinc, and returned into the hot dip galvanizing bath; so that the yield of zinc is increased.
JP2000355748 also discloses how to efficiently scrape top dross that floated up on the surface of a galvanizing bath, even in the very narrow portion near a steel strip, etc., pulled up from the galvanizing bath. In this device, the top dross floated up on the surface of the galvanizing bath is scraped. An arm is disposed as parallel with the bath surface. This arm is shifted in the width direction of a galvanizing vessel with an arm shifting mechanism. A scraping plate is fitted to the tip part of the arm. The scraping plate is elevated/lowered so that the lower end part of the scraping plate is dipped by a little below the bath surface with a scraping plate elevating/lowering mechanism. Even in the case of being very narrow portion, the top dross floated up on the surface of the galvanizing bath can efficiently be scraped and the sticking of the dross on the surface of the steel strip can efficiently be prevented.
The prior art JP11256298 provide a dross-removing device in galvanizing equipment, in which the structure is simple, and which has the durability and the high removing efficiency of the dross and no trouble in the operation. The document JP 11256298 describes that in a galvanizing part in the galvanizing equipment, a molten zinc vessel communicated with a galvanizing vessel and having melting function for coating metal and setting function for the dross, is arranged, and molten zinc for galvanizing is transferred and circulated from the galvanizing vessel to the molten zinc vessel through a piping with a pump. In this way, the dross transferred to the molten zinc vessel together with the molten zinc, is deposited with the molten zinc vessel to secure the cleanliness in the galvanizing vessel.
Another prior art document JP11152553 provides a dross-removing device with simple structure and high durability and high removing efficiency of the dross in hot dip galvanizing equipment, and a method therefore. The dross removing device is arranged by adjoining a galvanizing vessel and provided

6
with a dross depositing vessel having the volume larger than the volume of the
galvanizing vessel and a transferring means for transferring molten zinc between the galvanizing vessel and the dross depositing vessel and also, circulating. The transferring means is provided with transferring piping and pumps for circulating the molten zinc, and the piping has an inner pipe composed of castable ceramics, a reinforcing pipe at the outside thereof and an adhesive between these pipes. Further, this means is controlled so as to satisfy QO/QR<10 (not contain 0) in the case of using QR for flowing rate of the circulated molten zinc per unit time and QO for vol. of the galvanizing vessel.
JP10140309 describes dross-removing device for galvanizing equipments. The dross removing device of galvanizing equipment, which is capable of, simultaneously and efficiently removing bottom dross and top dross and is simple in construction. The plating section of the galvanizing equipment has a storage tank capable of floating, settling and separating the dross, and a transfer means for molten zinc between a plating cell and the storage tank in the position adjacent to the plating cell. The transfer means of the molten zinc from the plating cell to the storage tank comprises two systems; a means for transferring the settled dross and a means for transferring the floating dross. The means for transferring the settled dross is a system of ladling up and transferring the zinc melt in the lower cell part of the plating cell by a pump and the means for transferring the floating dross is a system of transferring the zinc melt near the liquid surface of the plating cell by overflow from a channel-like flow passage
A technique for recovery of zinc metal from a dross concentrate is disclosed in Ross et al, U.S. Pat. No.4,057,232. Ross discloses a method for separating molten zinc from dross by use of a press mechanism, which compresses the dross in a ladle and squeezes the free metal through openings in the ladle.
Kuwano et al, U.S. Pat. No. 4,003,559, teaches an agitating device which is designed to squeeze free metallic zinc from dross. In Kuwano et al, the dross is violently stirred in order to effect the separation of the free metal

7
from the dross. US patent No. 4,003,559 describes an apparatus for recovery of metallic zinc from dross.
The process of removal of zinc values from slag taught in U.S. Pat. No. 2,795,500 includes the step of injecting a molten dross pool with a combustible mixture of liquid fluid and oxygen-containing gas. This reduces the reducible zinc compounds and the zinc is thereafter volatilized. Another vaporization system is set forth in U.S. Pat. No. 2,844,462. U.S. Pat. No. 3,198,505 is an example of a reference relating to a metal recovery apparatus for stirring dross in a drum. U.S. Pat. No. 4,003,559 sets forth apparatus for squeezing zinc from dross. U.S. 4,075,008 teaches the formation of dross ingot placed on a permeable support and heated so as to melt zinc there from, the zinc being collected below the permeable support.
U.S. Patent No. 831,123 teaches a recovery apparatus comprising a fuel-fired brick furnace and a specially configured dross pan. The furnace is intended to bring the zinc values in the dross to the melting point whereupon they run out of the dross pan into a vessel by which they may be returned to the coating pot. U.S. Patent No. 1,821,105 teaches apparatus for the collection of bottom dross by means of an endless chain of buckets. Zinc values are obtained through the use of a steam of air actuated cylinder to compress the dross through a perforated container. U.S. Patent. No. 2,433,615 utilizes a retort and a vaporization process to recover zinc from dross.
U.S. Patent No. 2,463,468 again teaches a vaporization process wherein dross is melted under non-oxidizing conditions so as to evaporate zinc values there from. The zinc vapors are carried to a condenser and liquid zinc is recovered and cast into slabs. U.S. Pat. No. 2,481,591 relates to a method of treatment of aluminous dross. While an aluminum system is different from a zinc system, the reference is of interest as illustrating an exemplary dross recovery system utilizing a flux and rotation or oscillation of the treated dross. U.S. Patent No. 2,701,194 sets forth a process for recovering zinc metal and its alloys from zinc dross utilizing a low melting point flux composition.

In U.S. Patent No. 4,003,559, Kuwano, et al. note that a common practice in the art has been to agitate the dross manually to hasten the coalescing of the zinc droplets or particles, to drain zinc from the dross. It has been found that since the manual agitation of the dross is difficult and dangerous to perform, it is seldom performed efficiently, resulting in a high concentration of useable zinc remaining in the dross for recovery in a remote location rather than directly into the molten bath. Kuwano, et al. go on to suggest the use of a plurality of "scrape plates" for mechanical, rather than manual, agitation of the dross. The scrape plates are disposed within a container, which is separate from the main metal bath. The container has perforations or holes for draining coalesced.
Continuous galvanizing line operations result in the production of considerable quantities of dross. Of the dross produced, some 80% to 90% is top dross or skimming which float on the top surface of the bath of molten zinc alloy in the continuous galvanizing line coating pot. In such continuous galvanizing lines, several percent of the total zinc consumption may be lost to top dross. Although top dross can run from about 90% to about 94% total zinc, it is traditionally sold to zinc or zinc chemical producers at a considerably lower price than that paid for prime grade zinc .As a result, this represents a substantial economic loss to the galvanizer.
Prior art workers have made numerous attempts to recover zinc values from dross. Most of these attempts have been characterized by one or more drawbacks. Frequently prior art methods have been batch methods and have involved complex apparatus and difficult material handling problems including shaking, stirring, rotation or oscillation of the dross. Many prior art methods require a flux and/or tend to produce zinc fume, both of which present a pollution problem and/or a worker health problem.
Manually the removal of top dross is difficult due to heat and hazardous environment. But at the same time it is also necessary to remove the top dross otherwise it will affect the quality of galvanized sheet. The temperature of top dross on zinc melt is about 450 C, heat radiation affect the removal practice. It

9
has been observed that the dross consists of huge amount of zinc that is treated as a loss. For reversal of zinc from dross, efforts were made to add exothermic powder to top dross and it was mixed manually. Due to exothermic reaction the zinc was reversed back to liquid zone.
The disadvantages of the prior art may be substantially overcome by providing a new device for proper mixing of flux powder with dross in zinc melts in the galvanizing zinc pot. Consequently it is an object of the present invention to provide device that allows the mixing of flux and dross in such a manner to enhance the surface reaction between flux powder and dross.
SUMMARY OF THE INVENTION
Zinc is an easily oxidizable metal, and hence, a molten zinc bath in a melting furnace or the like has the surface covered with oxides. Further, this surface layer of oxide entangles therein a large amount of metallic zinc and its fluidity is very low. Accordingly, this surface layer of oxide generally is in the form of a hard and thick layer. For this reason, there is customarily adopted an operation of scattering a flux, generally a flux of the chloride type, on the surface of a molten zinc bath, separating and recovering metallic zinc involved in the oxide layer by manual agitation. By this operation, the fluidity of the oxide layer is increased and the majority of metallic zinc involved in the oxide layer is recovered into the zinc bath. However, a considerable amount of metallic zinc is still contained in the oxide layer mainly in the form of fine particles. This amount of residual zinc differs greatly depending on the configuration of the surface state of starting materials to be melted or on the fluxing method. For example, in the case of a starting material having a large surface area such as zinc sheets deposited in the electrolysis, the amount of such residual zinc is as large as 1 to 4% by weight based on the starting material. In case such mixture composed of zinc and its oxide ("dross") is treated in the zinc refining process, considerable processing expenses are required for this treatment. Therefore, various methods have heretofore been practiced to squeeze out the metal from the dross and thereby obtain a final product directly from the dross.

10
The conventional methods comprise charging into a vessel having
inclined bottom face dross scraped out of a melting furnace, agitating the dross manually by means of an iron rod provided with scrape plates and thus squeezing out metallic zinc from the dross. According to this method, just before or during the operation a flux or zinc dust is sometimes added to utilize the heat generated by the oxidation reaction. In this method, however, since agitation is performed manually, no uniform agitation can be attained and further, because of the individual metallic zinc particles having the surface covered with a thin oxide layer, the heat resulting from reaction with the flux cannot be utilized effectively. Therefore, the metal recovery ratio is relatively low, for example about 40% by weight. Further, considerable labors are required for practice of this method.
As another conventional method, there can be mentioned a method for obtaining crude zinc by melt-extracting a zinc containing material such as dross, hard zinc and zinc die-cast alloy scrap with use of a rotary furnace. This method is characterized in that a variety of starting materials including the above-mentioned, ash-like dross, scrap metal and chipped metal masses can be treated. Further, in this method, since a high agitation effect can be attained, there is obtained an advantage that the metal recovery ratio is increased. However, the apparatus used is a rotary furnace having a complicated structure and a large size, and since the ratio of filling of the starting material into the furnace is 10 to 40% at most and a large quantity of heat escapes from the furnace, the furnace should be heated directly or indirectly even when hot dross coming from a zinc melting furnace is treated. Moreover, when the ash-like dross is treated, a considerable amount of dusts is carried over from the furnace with its rotation and metallic zinc is partially oxidized and further, since chlorine compounds are contained in such dusts, they are deposited and fixed in ducts of a dust precipitator, resulting in blocking up of a gas passage.
One alternative is to cover the dross with a flux material or an inert atmosphere to prevent continued oxidation of the metal. While this is one

11
effective approach to reduce continued loss of zinc metal during recovery. Therefore the separation of the zinc from the dross requires the use of fluxes that preferentially attack the magnesium in the alloy and cause corrosive fume, high temperatures and violent mechanical agitation. This procedure must be carried out in a separate furnace with the correct equipment such as stirrers, fume extraction hoods and air filters.
When the exothermic flux are in the form of powders or have a low specific gravity are introduced into the bath by means of a carrier gas do not lead to satisfactory results in all cases, given that the mixing which accompanies the introduction of the additives is neither intense nor prolonged enough to guarantee intimate contact of the dross and the flux or to bring about a homogeneous dispersion of the flux throughout the contents of the receptacle It is therefore generally necessary to provide for a separate mixing and homogenization treatment.
The present invention eliminates the most dangerous and difficult part of the dross removal operation the lifting of the dross -laden basket from the bath.
More specifically, in accordance with this invention, there is provided an apparatus for recovering metallic zinc in dross discharged from a zinc melting furnace, which comprises a device for proper mixing of flux powder with dross in zinc melt in the galvanizing zinc pot consisting of a table to hold two steel pipes; one jack; four wheels; a reversible motor attached with two pulleys; a reversible switch and a stainless steel cylinder with both end open, having a stirrer attached with pulley. In particular, the present invention is directed to the mixing process, which enhances the surface reaction between exothermic flux powders and dross. Due to exothermic reaction the zinc was reversed back to liquid zinc. The entrapped zinc is removed from dross due to proper mixing and heat.

The invention process can be best described in connection with the exemplary system illustrated in the Figure 1. The improved dross reclaiming

13
device for proper mixing of flux powder with dross in zinc melt in the galvanizing zinc pot for which the improvement is intended has a substantially:
(i) a table (C) to hold two steel pipes; steel box (D) to hold pipes; one jack (H); four wheels ;steel box (E) to hold wheels; supporting rods to hold both the ends of stainless steel pipe;
(ii) a reversible motor attached with two pulleys fixed with two steel pipes (B);
(iii) a reversible switch to change the direction of motor;
(iv) a stainless steel cylinder with both end open, having a stirrer attached with pulley, where both stainless steel cylinder and stirrer are held in box (F). These components are made of stainless steel which are in contact of liquid zinc;
(v) a jack was used to raise stainless steel cylinder and stirrer with stainless steel blade (G) from liquid zinc.
The device was designed, fabricated as per space available for application in actual working place in galvanizing line of Bokaro Steel Plant. The portion of the equipment, which is put in liquid zinc, was fabricated from 5mm thick stainless steel pipe of 250mm diameter. The supporting rod was 18 mm diameter that was holding both ends of stainless steel pipe. The propellers were also fabricated from 5mm thick stainless plate to avoid the hot corrosion due to zinc melt. The device was shifted near to zinc pot and stainless steel pipe was submerged in liquid zinc in such a way that only dross portion should be under mixing region. The required quantity of flux was put into stainless steel cylinder. The enclosed amount of dross and flux was stirred with the help of motor in clock and anti clock wise. The mixing was found proper and quick. When generation of gases ceases, the stainless steel cylinder along with stirring blades is raised with the help of jack fixed at mid point of motor and cylinder. The ash was skimmed and collected outside. Stainless steel cylinder and stirrer can withstand the liquid zinc temperature.

14
The device to which the present improvement is applicable also has a
motor attached with two pulleys fixed with two steel pipes by which the positioning of the motor can be smoothly done. Means for raising and lowering the motor support carriage relative to the motor support arm are provided, which act to move the motor and the motor support carriage between the raised motor position and each of the at least one lowered motor positions. Such means can be provided by any of the various mechanisms known in the art for raising and lowering an element of a structure. The use of one or more reversible switches is particularly useful to adjust the lowest lowered motor position to prevent impact of the reaction vessel by the propeller. By adjusting the position of the reversible switch, the lowest lowered motor position can be altered for different configurations of propeller and/or reaction vessel.
In a preferred embodiment, the motor support arm is rotatably mounted to the substantially vertical support to allow the motor support arm to rotate about a substantially vertical axis in clock and anti clock wise between the loading/dumping position and the operating position. The nature of the motor drive source depends on the type of the motor employed. In the case where the motor is an electric motor, the motor drive source is the electrical connection, while in the case of a hydraulic motor; the motor drive source is the pressurized fluid.
In particular, the present invention is directed to the mixing process, which enhances the surface reaction between exothermic flux powders and dross. Due to vertical support which can be positioned near the zinc pot, a cylinder is provided for containing the dross during the recovery process and the stainless steel pipe was submerged in liquid zinc in such a way that only dross portion should be under mixing region.
The invention allows intimate, effective and continually renewed contact between the dross which is to be treated and the product or medium serving for the treatment to be ensured during the performance of a wide diversity of metallurgical treatments and thus serves to render the reactions faster and more complete.

15
When it is desired the system/device of the present invention can be modified in several ways:
(i) this system can be modified for removal of gas generated due to reaction between flux and dross;
(ii) the system can also be modified for removal of fine ash powder automatically by using vacuum system;
(iii) by using programmed controller, the propeller in the system can be made spinning in clock and anti clock automatically. Although the programmed controller can be built with dedicated circuits, it is preferred to employ a microprocessor with appropriate instruction sets to facilitate the automation of the operation, since its programming allows great flexibility to allow a broad range of cycles to be handled by a single control system; and
(iv) the flux in the system can be fed automatically using screw feeder.
In the following description of the device and system of this invention and the apparatus illustrated in the Figure 1, reference is made specifically to zinc and to a single preferred embodiment of the invention. The invention, however, encompasses the use of the same process and system for any galvanizing pot and also encompasses variations from the preferred embodiment, which is merely exemplary of the invention and is not intended to circumscribe or to define the invention.
