[0002] CSP continuous casting machine is a typical and mature thin slab continuous casting and rolling equipment. During the production process, the sector and the rollers on the sector need to be repaired according to the amount of steel overload in the sector or the abnormal surface of the sector roller. When repairing the sector and roller group, in order to save time and improve the repair efficiency, generally only the roller surface needs to be polished, and only when there are serious problems such as steel leakage and severe scratches, the roller needs to be disassembled for repair.

[0003] At present, when polishing the surface of the sector roller, the current operation method is to turn the roller by hand and use an electric wire brush to polish the roller surface. On the one hand, this method will lead to uneven roller speed, which will cause uneven roller polishing coverage, and some may appear over-polishing, under-polishing and other phenomena, making it difficult to control the polishing quality; on the other hand, the polishing efficiency is low and the labor intensity of the operator is high. For this reason, we propose a driving device for repairing the sector roller of a continuous casting machine. Utility Model Content
