Twin Roll Casting Rolling Machine and Twin Roll Cast Rolling Process

摘要

A twin-roll continuous casting machine (100) in which molten steel (106) is supplied to a moving die consisting of a pair of rollers (101, 102) rotating in opposite directions and a pair of end faces of the rollers (101, 102). 102), wherein a cast part (113) formed by pressure-bonding solidified jackets (111, 112) solidified to surfaces of the rolls (101, 102) is defined by a space between the rolls (101 , 102) is pulled out; each of the rollers (101, 102) having, at the opposite ends in the roll axis direction, steps (101a, 101b, 102a, 102b) of larger diameter than that in the central portion of each of the rollers (101, 102); characterized in that a heat insulator is applied to peripheral surfaces of the steps (101a, 101b, 102a, 102b) of the rollers (101, 102), and the rollers (101, 102) are arranged so that their steps (101a, 101b, 102a , 102b) are in contact with each other in a portion with minimum clearance between the rollers (101, 102).
