摘　　要：根据国内外冷轧厂生产经验,带钢平整厚度>0.5 mm时容易出现边部横折纹。认为带钢产生横折纹的主要原因是原料板型不良、退火粘卷、平整设备精度差等。通过调整原料板型、退火温度曲线、保证设备精度等措施,可以有效控制和预防带钢边部横折纹的产生。According to the production experiences in cold rolling mills at home and abroad,the edge cross folding line on strip steel is easily occurred when its temper thickness larger than 0. 5 mm. It is considered that the main reason is bad profile shape of raw plate,coil sticking in annealing,tempering equipment not precise. With some measures adopted against to the above problems,the edge cross folding line can be effectively controlled and prevented.
