Abstract (en)

Variations in the shape of a metal sheet generated at the time of quenching are suppressed.A metal-sheet quenching apparatus 1 cools a metal sheet while conveying the metal sheet and includes a cooling device 10 that cools a metal sheet S that is conveyed; restraining rolls 20 that convey the metal sheet S cooled by the cooling device 10 while restraining the metal sheet S in the thickness direction; a roll moving device 30 that moves the restraining rolls 20 in the conveyance direction of the metal sheet S; and a movement control device 40 that controls the operation of the roll moving device 30 to adjust the position of the restraining rolls 20.
