X80管线钢轧制工艺稳定性探讨

摘要

The rolling of X80 pipeline steel features high rolling force and high torque,especially for wider prod-uct,and thus requires higher accuracy of rolling force prediction. It is also easily to encounter the phenomenon of pass number skip in the course of rolling,which brought negative effect on flatness control,finish rolling temperature,start cooling temperature and retempering temperature. Based on the features of X80 pipeline steel rolling,the article recom-mends the control measures to improve rolling force prediction accuracy and the measures to eliminate pass number skip,which is of referencing significance for the same type product rolling.%宽规格 X80管线钢的轧制具有大轧制力、大扭矩的特点，因此对轧制力的预测精度要求更高。X80管线钢在轧制过程中容易出现道次数变化的现象，给板形控制以及终轧温度、开冷温度、返红温度等带来不利影响。针对 X80管线钢的轧制特点，提出了提高轧制力预测精度的控制措施以及跳道次现象的抑制措施，对于同类产品生产具有一定的参考意义。
