摘　　要：热轧钢卷卷形质量是带卷产品质量控制的一个重要组成部分,控制好带钢卷形质量不仅会降低生产成本,还会提升产品在行业内的形象地位和市场竞争力。本文对唐钢新区2050热轧线在生产过程中经常产生的塔形、层错、扁卷等典型卷形缺陷进行了介绍,分析了卷形缺陷产生的原因,并提出了控制措施。通过优化加热炉出钢程序、提高设备功能精度、加强员工能力培训、优化卷取夹送辊辊型、优化卷取机芯轴张力参数等措施,使2050热轧线卷形缺陷比例得到了有效控制。The coil shape quality of hot rolled steel coil is an important part of the quality control of coil products,controlling the coil shape quality of strip steel well will not only reduce the production cost,but also enhance the product’s image status in the industry and market competitiveness. This paper introduces the typical coil shape defects such as tower shape,stacking fault and flat coil,which often occur in the production process of 2050 hot rolling line in Tanggang new area,analyzed the causes of coil shape defects,and put forward the control measures. Through optimizing the tapping program of the heating furnace,improving the functional accuracy of the equipment,strengthening the ability training of employees,optimizing the roll shape of the coiler pinch roll,optimizing the tension parameters of the coiler mandrel and other measures,and controlled effectively the coil shape defect proportion of 2050 hot rolling line.
