摘　　要：结合河钢集团宣钢公司小型轧钢厂3/4连续式热轧窄带钢生产情况,重点分析了带钢间断性拉窄、头尾超宽中间合格、通条超宽(超窄)、宽度时宽时窄等几种情况下宽度超差的原因,并提出了相应对策。改进后,带钢宽度控制精度明显改善,为提升宣钢产品档次奠定了基础。Abstract： Based on the production situation of 3/4 continuous hot -rolling narrow strip steel in the small steel rolling mill of Xuansteel company, the causes of width off - tolerance are mainly analyzed in the cases of the discontinuous pulling narrow, both ends over - wide, whole strip over - wide （ or over - narrow） and width instability; and the countermeasures have been taken. The width control precision is dramatically promoted after the improvement, which has established the foundation of improving product grade of Xuansteel company.
