摘　　要：介绍了1780 mm冷连轧机组厚度0.5 mm以下薄带钢停车后再起车的控制方法。对薄带钢停车后再起车失败原因进行了分析,提出采用厚头起车的方法,解决了薄带钢起车勒辊、断带等问题,使厚度0.5 mm以下薄料停车再起车成功率达到100%。同时提高了机组产能和作业率。This paper introduces the method for controlling the 1780 mm tandem clod mill for producing a steel strip with thickness of less than 0.5 mm when restarting it after shut-down.The cause leading to the failure for restarting the mill is analyzed,and then this paper proposes the method for restarting rolling from the thick end of the steel strip so that such problems as tightening of rolls and breaking of the steel strip are solved,resulting in restarting the mill with the rate of success 100% in producing the steel strip with thickness of less than 0.5 mm after shut-down and further the production capacity and the operation rate of the mill are also increased.
