[1]The invention, such as rolling oil or pretreatment solution relates to a reproduction system including iron removal apparatus and to remove it the iron of the solution containing the iron.
BACKGROUND
[2]In general, the processes such as cold rolling process, plating process, electrical steel sheet in the step of using a fluid such as a rolling oil or the pre-treatment solution, and then using a fluid to recycling to remove impurities increases utilization.
[3]
For example, in the cold rolling process of the steel process, the rolling mill stand and injecting the rolling oil to the rolling roll and the steel sheet in (Mill Stand).
[4]
At this time, the rolling oil can contain iron generated in the rolling mill stand, these rolling oil, the iron scum (foam in the form of liquid debris, including iron), since the high temperature frictional heat and pressure (push-down force) generated by the friction between the rolling roll and the steel sheet is Occurs.
[5]
On the other hand, these rolling oil can be recycled to maintain cleanliness by removing iron scum through the playback system.
[6]
1 is a schematic diagram of a playback system according to the prior art.
[7]
Referring to Figure 1, the reproduction system 1 is utilized for reproducing a fluid such as a rolling oil used in the rolling mill (50). To this end, conventionally, the initial rolling oil stored in the main tank 10 is supplied to the mill 50 through a fixed screen filter 12 along the pipe is injected between the steel sheet (S) and the surface of the rolling roller (52).
[8]
In addition, after passing through the rolling mill 50, the rolling oil for lubrication, cooling and cleaning function is stored in the return tank 14, is first purified by car scum iron and foreign matter from the filter Hoffman (Hoffman Filter) (16). And, rolling oil that has passed through the Hoffman filter 16 is composed of a continuous circulation purified by the magnetic filter (20) provided in the dirty tank (18) to move to the dirty tank (Dirty Tank) 18.
[9]
And the internal one has a magnetic bar (19) of the dirty tank 18 is installed, the magnetic bar (19) is collected by the iron contained in the rolling oil transferred to the external tank to remove the iron and the like.
[10]
On the other hand, the rolling oil, iron is removed by a magnetic bar (19) in the dirty tank 18 becomes transferred to the clean tank (Tank Clean) (22) to complete the regeneration cycle.
[11]
If this way, the refresh cycle is complete, the rolling oil is back through the main tank 10, the rolling roller 52 and there is provided a rolling mill (50) comprising the same, the purity of the purified recycled rolling oil is not secured, by the foreign matter in the rolling oil as well as the occasional replacement frequency of the rolling roller 52 is increased in productivity and reduced, it can lead to surface defects of the rolled steel plate quality (S).
[12]
Therefore, the rolling roller 52 and in order to ensure the cleanness of the rolling mill (50) comprising the same, and need an efficient removal of the iron contained in the rolling oil, rolling oil, provided to the rolling roller 52 and the rolling mill (50) comprising the same of the steel sheet (S) bond minimum quality, then processing load reduction, the surface quality improvement by the cleanliness obtained can contribute the like (for example, the surface quality of the rolled steel plate, etc. to the high-end of the automobile steel sheet) and rolling oil consumption cost savings.

[43]
Example iron removal apparatus 100 of the embodiment can be installed in a part of the reproduction system for reprocessing to recover the fluid used in the steelmaking process, it is possible to remove the iron powder in the process of reprocessing fluid.
[44]
To this end, the iron removal apparatus 100 includes a drive 110 having a drive motor and, one end magnetic wheel 120 is connected to the rotation shaft of the drive motor can rotate.
[45]
Magnetic wheel 120 may be provided to the wheel having a magnetic force, this magnetic wheel 120 is that in a state charged into the fluid to be circulated for recycling rotated by the driver 110, to the fluid by the magnetic force in this process It can be adsorbed to provide ever contained iron.
[46]
On the other hand, and one side of the drive section 110 can connect the lifting unit 130, the magnetic wheel 120 by the operation of the lifting unit 130 can adjust the height devoted to the fluid. In addition, the top of the vertical part 130 may be provided with a support portion 140 for supporting the like to the playback system, the tank that is specifically the fluid is stored.
[47]
On the other hand, the magnetic wheel 120 during rotation in injected into the fluid state, the lower portion of the magnetic wheel 120 to cause the rising flow of the fluids, that is, the other end has an impeller 121 causes a rising flow of the fluids may be provided .
[48]
The impeller 121 is provided with a plurality of rotor blades, while rotating together when rotated the magnetic wheels 120 by the driver 110, and the fluid to form a rising flow.
[49]
Accordingly, the foreign materials such as the iron contained in the fluid, but may be deposited in the lower fluid by the difference in specific gravity, and is circulated by the upward flow generated by the impeller 121 may be adsorbed to the magnetic wheel 120.
[50]
Magnetic wheel 120 in the present embodiment, driver 110, that is, at least one magnetic member outer peripheral surface including a cylindrical cylinder (122) which one end is connected to the drive motor rotary shaft, and a cylindrical cylinder 122 ( 124) can be coupled.
[51]
[52]
* Where magnetic member 124 may be formed of a permanent magnet, and outside the cylindrical cover covering the outside of the magnetic member 124 to prevent foreign matter such as iron powder is directly attached to the magnetic member 124 (126 ) it may be combined.

That is, the magnetic member 124 of a samarium cobalt-based is to maintain the magnetic force even when the temperature of the fluid is less than 700 ℃ However, it is generally the temperature of the fluid can be a magnetic force of about or below 350 ℃. Accordingly, the magnetic member 124 of a samarium cobalt-based is preferred that the temperature of the fluid used to not more than 350 ℃.
[62]
On the contrary, if the temperature of the fluid to be applied to more than 700 ℃, alnico (Alico) may be used magnetic member 124 in the series.
[63]
Alnico (Alico) magnetic member 124 in the series is the magnetic force is low, but in comparison to the magnetic member 124 of a neodymium-based magnetic member 124 or samarium cobalt class of, even at a high temperature not less than 700 ℃ than the other magnetic member 124 it is possible to maintain the magnetic force.
[64]
Here, the neodymium being for the series magnetic member 124, a samarium cobalt-based magnetic member 124 and the alnico-based magnetic member 124 of the, used for the following 100 ℃, less than 350 ℃ and below 700 ℃ fluid described. However, the temperature is limited here does not imply a limit temperature, but is not limited to the critical upper limit to the maintenance and management costs and, separated in accordance with the effective temperature.
[65]
On the other hand, the impeller 121 may be provided in a non-magnetic metal to prevent the suction foreign matter such as iron powder. In one example, the impeller 121 may be made of titanium nitride (TiN) an aluminum or stainless steel coating is formed on the outside.
