造される。For example, in a continuous processing facility disclosed by the present applicant in Japanese Patent Application Laid-Open No. 53-132437, a hot-dip plating tank is disposed so as to be movable up and down downstream of a continuous heat treatment furnace. In this apparatus, when manufacturing cold-rolled steel sheets, the hot-dip plating tank is lowered to form a pass line that does not pass through the plating bath. In the process of manufacturing plated steel sheets, the hot-dip plating tank is raised to form a pass line that passes through the plating bath. This allows both plated and cold-rolled steel sheets to be manufactured in a single facility.

クロール４に送られる。In the hot-dip plating bath 1, the plating portion is isolated from the outside air by a tank wall 2.degree.3 whose lower end is immersed. Thereby, the hot-dip plating bath 1 is separated into a liquid level facing the plating part and a liquid level outside the tank wall 2.3. Outside this area, plating metal injection, maintenance work, etc. are performed. Furthermore, a partition wall 5 is erected above the inlet deflation crawler 4 provided near the tank wall 2. The inlet deflation crawl 4 is arranged closer to the liquid surface of the hot-dip plating bath 1 than the conventional deflation crawl. Then, the steel plate 6 that has passed through the overaging chamber 80 and the reheating furnace 81 (see FIG. 2) is sent to the entry side deflation crawl 4 through between the tank wall 2 and the partition wall 5.

に沿って、鋼板６を走行させる。In the process of producing a plated steel plate, the steel plate 6 is sent along a pass line passing through the plating bath 1 and conveyed upward through a zinc roll (not shown). During the process of passing through this hot-dip plating bath 1, the surface of the steel plate 6 is plated. Then, the excess plating metal adhering to the surface of the steel plate 6 is removed from the steel plate 6.
After leaving the hot-dip plating bath 1, it is removed by a wiping device (not shown). On the other hand, in the cold-rolled steel sheet manufacturing process, a pass line L that does not pass through the hot-dip plating bath 1 but directly goes from the inlet deflation crawl 4 to the deflation crawl 7 for cold-rolled steel sheets.
The steel plate 6 is made to run along.

。そして、外側絞りロール８ａを退避させる。To move the steel plate 6 from the solid line position to the dotted line position,
Pull the steel plate 6 from the exit side to make the steel plate 6 tension. Then, the inlet deflation crawler 4 is driven to continue transporting the steel plate 6 for a predetermined period of time, and the plated metal adhering to the steel plate 6 is removed. Further, the steel plate 6 is allowed to pass for a while until the plated metal adhering to the drawing roll is removed by the steel plate 6. Then, while conveying the steel plate 6, the inner squeezing roll 8b is raised and retracted, and the steel plate 6 is wound around the exit side deflation roll 7. Then, the outer squeezing roll 8a is retracted.
このようにして、メッキ鋼板製造工程から冷延鋼板製造
工程への切換えが完了する。In this way, the switching from the plated steel sheet manufacturing process to the cold rolled steel sheet manufacturing process is completed.

金属を収容している。The squeezing device includes a pair of squeezing rolls 3a and 3b provided on both sides of the conveyance path for the steel plate 6 pulled up from the plating bath 1. The outer squeezing roll 8a moves back and forth in a direction perpendicular to the surface of the steel plate 6 using a cylinder 9. The inner squeezing roll 8b is rotatably provided at the tip of the arm 10, and moves about the pivot shaft 11 between the solid line and the dashed line. Further, there is a tray 12 below the inner squeezing roll 8b which is in the retracted position shown by the - dotted chain line.
is provided to accommodate the plated metal falling from the squeeze roll 8b.

せる。また、アーム１０を旋回させることにより、内側
の絞りロール８ｂを鋼板６の反対側表面に当接させる。When the wiping device is retracted, the cylinder 9 pushes out the outer squeezing roll 8a and brings it into contact with the surface of the steel plate 60. Further, by rotating the arm 10, the inner squeeze roll 8b is brought into contact with the opposite surface of the steel plate 6.
このようにして、鋼板６を絞りロール３ａ、 ８ｂで挟
み込み、鋼板６の表面に付着しているメッキ金属１３を
絞り取り、メッキ浴１に落下させる。In this way, the steel plate 6 is sandwiched between the squeeze rolls 3a and 8b, and the plated metal 13 adhering to the surface of the steel plate 6 is squeezed out and dropped into the plating bath 1.

The amount of plated metal adhering to the steel plate 6 sent to b gradually decreases. Then, the portion to which the plated metal is excessively adhered passes through the squeezing rolls 3a and 3b. When the sheet threading is continued further, the plated metal adhering to the inner drawing roll 8b begins to adhere to the steel sheet 6 instead.

る。The state of adhesion of the plated metal to the inner squeezing roll 8b is detected by appropriate means. Then, when the adhesion of plated metal is no longer detected, the inner squeezing roll 8b is rotated about the pivot shaft 11 and moved to the retracted position shown by the - dotted chain line. Thereby, the inner squeeze roll 8b is held at a position where it does not interfere with the pass line L for the cold rolled steel sheet. Next, the steel plate 6 is wound around a differential roll 7 for cold-rolled steel plates, and the process moves to a cold-rolled steel plate manufacturing process.

’ｖＶｃ。In this way, by squeezing out the plated metal excessively removed from the plating bath 1 due to the inoperation of the wiping device using the squeezing rolls 8a and 8b, the plated metal is not brought into the subsequent process. Therefore, troubles such as abnormal operation caused by adhesion of plated metals of various mechanical parts and the like are eliminated. In the case of hot-dip galvanizing, the drawing rolls 3a and 3b are made of the same material as the zinc roll, which has corrosion resistance against the plated metal, such as Leatheroy or Hastelloy, or ZRO2.

われ、設備の稼動効率も向上する。As explained above, in the present invention, when switching from a plated steel sheet manufacturing process to a cold rolled steel sheet manufacturing process, since the wiping device is not operating, the plated metal excessively attached to the surface of the steel sheet is squeezed out by a squeeze roll. There is. Then, when the plated metal is not substantially attached to the surface of the steel plate, the steel plate is wound around the outlet deflector roll. Therefore, the plated metal is not brought into the subsequent process, and troubles such as abnormal operation do not occur. Furthermore, since the plated metal adhering to the surface of the steel sheet is squeezed out using a squeeze roll, the process can be quickly switched from the plated steel sheet manufacturing process to the cold rolled steel sheet manufacturing process, improving the operating efficiency of the equipment.
