ABSTRACT:
A method of rapidly and uniformly widthwise cooling a cast stainless steel strip when casting the strip by using a vertical type twin-roll continuous caster provided with a pair of cooling rolls having an outer circumferential surface composing a casting mold wall moving synchronously with the cast strip, which comprises the step of: pressing a cast strip having left a kissing point between the cooling rolls against the circumferential surface of one of the cooling rolls with a press roll disposed downstream of the kissing point and having a press roll surface geometry predetermined in accordance with a cooling roll crown and a cast strip crown, to rapidly cool the cast strip over the entire strip width, successively from the strip solidification completion and over a temperature range in which the growth of solidified grains of the strip is accelerated.
