摘　　要：分析了唐钢1580 mm热轧机生产线生产冷轧基板过程中出现带钢头部拉窄的问题,通过对拉窄位置的测量以及仪表检测情况的调查,确定冷轧基板头部产生拉窄的主要原因来自卷取区域,因此针对性地优化了冷轧基板的卷取张力等相关参数、层冷的冷却模式,完善了卷取的一级控制程序,精确了卷取操作人员的控制要点,有效解决了冷轧基板头部宽度拉窄的问题,满足了用户切边对宽度的要求,同时也提高了公司产品的宽度控制精度,保证了产品的质量信誉。This paper analyzes the problem of strip head narrowing in the production of cold-rolled base stock by 1580 mm hot continuous rolling mill line of Tang Steel.Through the investigation of the narrowing position and instrument detection,it is determined that the main reason for the narrowing of the cold-rolled base stock head comes from the coiling area.Therefore,the relevant parameters such as coiling tension of the cold-rolled base stock,the cooling mode of layer cooling,the primary control program of coiling,the control points of coiling operators are improved,the narrowing of the width of the cold-rolled base stock head is effectively improved,the requirements of the user on the width of trimming are met,and the products of our company are also improved.
