热轧带钢宽度不良原因分析及改进

Causes Analysis and Improvement Measures for Width Deviation of Strips Produced by Hot Strip Mill

文章分析了2250热轧板厂过程控制参数宽度指标的控制现状。对影响产品宽度的因素:来料异常、仪表检测异常、操作干预不当、模型精度、设备动作精度、精轧拉窄等进行了分析,并结合现场实际情况提出了解决方案。

This paper analyzed current width control status of 2250 hot strip mill. And the factors which influenced the width of coils are studied, including unusual incoming slabs, abnormal instrument measurement, incorrect operation, model accuracy, equipment accuracy and narrowing of finishing mill. Meanwhile, countermeasures are proposed in accordance with actual situation on site.
