Abstract (en)
There is provided a quenching apparatus which produces a good cooling effect on a metal sheet, which facilitates switching between a condition of performing quenching and a condition of not performing the quenching, and which can suppress thermal deformation caused by thermal radiation from the metal sheet.A quenching apparatus 11 includes a bath 5 that contains a cooling medium 2 in which a metal sheet 1 is immersed and at least one pair of rolls 4 (a roll 4a and a roll 4b) which are disposed such that the metal sheet 1 running in the bath 5 is interposed between the at least one pair of rolls 4 (the roll 4a and the roll 4b) in the bath 5, distances of which from the metal sheet 1 are changeable, and which rotate at a peripheral speed higher than or equal to a running speed of the metal sheet 1.
