摘　　要：国外某钢厂新建板坯连铸机,在生产初期各扇形段辊电机经常会出现负荷不平衡的现象,因而影响整个连铸机驱动系统的驱动性能及使用寿命。针对此问题,采用PLC速度闭环控制模型,变频器的矢量控制,增加下垂功能控制和动态负荷平衡模型微调的控制策略,实现了负荷平衡的控制功能。该方法有效提高了板坯的生产质量,保证了生产节奏。At the beginning of production, a new slab caster built in a steel plant abroad is always load imbal- ance in each segment roll motor, so affecting the driving performance and service life of the whole driving system. In response, the author adopts PLC speed closed - loop control model, V/f control, droop function control and dynamic load balance model to implement the electrical control of load balancing. This method effectively improves the production quality of slab and ensures the production rhythm.
