摘要： Intended is to provide a casting roll having an outer periphery capable of being efficiently cooled.
The casting roll has a roll body on which side weirs 11 abut, short tube-shaped supports 13 each coaxially with and protruding from the roll body 12, a stub axle 14 fitted into the support 13, a sleeve 15 fitted over the support 13 and a flange 16 contiguous with the stub axle 14 and abutting on the sleeve 15 on a side away from the roll body 12. The roll body 12 is formed with longitudinal cooling passages 17 passing through the roll from one end to the other end of the roll as well as radial cooling passages 18 each adjacent to a corresponding end of the roll and extending from an inner periphery of the roll to a corresponding longitudinal cooling passage 17. A plug 19 is fitted into each end of the longitudinal cooling passages 17 and abuts on the sleeve 15. With distance T3 between the longitudinal cooling passages 17 and the outer periphery of the roll body 12 being reduced as much as possible, cooling water W is passed through a surficial portion of the roll body 12.

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.

摘要翻译： 即使在侧面堰上形成弓形磨损步骤，也希望获得厚度较小的钢带。 在具有弧形磨损步骤6的双辊铸造机的操作期间，由于冷轧辊1的旋转滑动接触而在侧堰2上显影，其中来自压区G的钢带3的厚度将被减小， 辊1之间的中心距离L随着侧面堰2与辊的端部向上移位而减小。 这防止了辊1的外周边缘与侧堰2的弓形磨损步骤6相邻的边界面8的干涉。
