Abstract (en)
Variations in the shape of a metal sheet generated during quenching is suppressed.A metal-sheet quenching apparatus 1 cools a metal sheet S while conveying the metal sheet S and includes a cooling tank 11 in which a cooling fluid CF is to be stored and the metal sheet S is immersed in the cooling fluid CF to be cooled; restraining rolls 20 that are installed inside the cooling tank 11 and convey the metal sheet S that has been cooled in the cooling tank 11 while restraining the metal sheet S in the thickness direction; a water-level adjustor 30 that adjusts the height of a fluid surface of the cooling fluid CF inside the cooling tank 11; and a position control device 40 that adjusts the height of the fluid surface of the cooling fluid CF inside the cooling tank 11 by controlling the operation of the water-level adjustor 30.
