OPERATING METHOD FOR TWIN-ROLL CASTING MACHINE |
摘要 |
Intended is to acquire a strip with less thickness even if arcuate wear steps are formed on side weirs. During an operation of a twin-roll casting machine with arcuate wear steps 6 developing on side weirs 2 due to rotational sliding contact of chilled rolls 1, where thickness of a steel strip 3 from a nip G is to be reduced, center-to-center distance L between the rolls 1 is reduced with the side weirs 2 in contact with ends of the rolls being displaced upward. This prevents interference of outer peripheries of the rolls 1 with boundary surfaces 8 adjacent to the arcuate wear steps 6 of the side weirs 2. |
