Abstract

PURPOSE:To produce the composite roll for continuous casting free from bending and cracking owing to high temperature by securing a sleeve made of heatresisting steel or padding layer onto the roll shaft having a cooling water hole at its center through shrinkage fit, etc. CONSTITUTION:In a method of immediately rolling a continuously cast slab or the like in succession, bending or cracking occurs owing to the high temperature of the slab because pinch rolls and guide rolls are not water cooled together with the slab. To prevent this the abovementioned roll is constructed by securing a sleeve 1 made of heat-resisting steel or padding layer 7 of the following composition onto the outside of a roll shaft 2 made of ordinary steel or low alloy steel provided with a cooling water hole 4 at the shaft center through shrinkage fit, welding, etc. and cooling the roll from the inside. The heatresisting steel contains C; 0.2-0.6%, Si; 0.1-3%, Mn; 0.1-3%, Cr; 15-35%, Ni; 10-40%, or further one or two or more kinds of Mo; 0.1-5%, W; 0.1-5%, N; 0.05-0.3% and the rest consisting of Fe.
