The present invention is to effectively cool the metallic material of various sizes, the present invention relates to a metallic material cooling device capable of reducing the vibration of a metallic material.
[2]
BACKGROUND
[3]
Information described in this section is placed out simply not necessarily constituting prior art only provides background information for the present invention.
[4]
1 is a schematic view showing a plating line of a common steel sheet, Figure 2 is a plan view showing that the cooling medium is injected by the coated steel strip cooling device according to the prior art a steel sheet.
[5]
1, the pay-off reel (Pay Off Reel) steel plate (cold-rolled steel sheet) 1 after the heat treatment after the welding machine and the looper, switch the sink roll 4 and the stabilization of nawooteu the bath (2) unwound from a roll of a high pressure (5) for the molten metal for example, molten zinc 3 is attached to the surface of the steel strip 1, a gas wiping equipment on the plating bath 6 (also known as "air knife") as it passes through the and a gas (inert gas or air) injected to control the coating thickness of the steel sheet (1).
[6]
Then, the coated steel strip (1) has damping facility 7 and cooling 8 and a feed through the roll 9, as progress plating makin done, for vibration equipment plate (1) through the gas wiping area to suppress vibration in the control and uniform coating thickness.
[7]
[8]
Since here, the cooling equipment 8 is provided on both sides of the steel plate 1 to be generally perpendicular to the transfer, also known as cooling towers (cooling tower).
[9]
Thus, cooling (8) of the same plated steel sheet is, the temperature of the steel plate (1) until immediately before the solidification of the zinc plating layer of the liquid attached to the plated surface of the steel sheet in a high temperature that the vertical feed and a feed roll (9) to less than 300 ℃ an important facility to ensure rapid cooling to smoothly transfer the subsequent step or the subsequent plate (1).
[10]
[11]
In this case, a conventional cooling facility has a spray nozzle 13 provided at a predetermined baton in injection chamber 12, which faces to both sides of the steel plate 1 to be vertically transferred is formed as shown in Fig.
[12]
However, the arrangement width of the injection nozzle 13 is fixed larger than the maximum width (L1) of the plate (1) that is at least coated production. Therefore, when the width (L1) of the plate (1) to be coated is in progress it is less than the cooling medium ejection width (L2) through the injection nozzle, the steel strip 1 in the area A does not have the cooling fluid injected at a high pressure to a conflict is being It is a vortex amplifier.
[13]
After all, such a vortex amplifier is to amplify the vibration of the edge portions in both side edges of the steel plate 1 to be vertically transferred.
[14]
In particular, the steel sheet (1) of the case of the / wide material the greater width is large and the impact pressure the width of the vertical jet of air, the upper side and both sides of the lower side is a strong vortex flow generated by the mutual collision of the injected air plate (1) there is a problem that the vibration of the edge can be significantly increased as compared to the narrow-pokjae.
[15]
The vibration increase of the same steel plate (1) there is a cause that leads to various problems in the plating line, stabilizer rising roll 5 for reducing vibration and increases the tension applied to the feed roll 9 and the wear of the roll it is to be increased, of course, as the lowered cooling performance, and also, making it difficult to increase the plating rate of the steel strip 1 by means of vibration, there arises the problem that their productivity is lowered.
[16]
And, there is a critical point that in the production of narrow coated steel strip width as shown, the plate (1) is sprayed over the cooling medium in the area outside of the cooling range in the width direction, whereby overloading of the blower is, of course, the cooling efficiency is even reduced . Which acts in a variety of causes of lower productivity.
[17]
Therefore, reduction of the vibration plate, for increasing the cooling performance and the increase, the line speed (Line speed) are situation urgent to develop a steel plate cooling apparatus which can improve productivity.
[18]
In the art of the present invention, a utility model No. 1989-0002975 No. a (Muju be the leading end of the hot-rolled sheet cooling unit, Filing Date: December 24, 1998, applicant POSCO).
