简要介绍了不锈钢1780mm热连轧生产情况和板形控制技术。从板形控制的角度分析了不锈钢与碳钢混合轧制和集中轧制的区别。结合计算结果和生产实绩,分析了典型不锈钢与碳钢混合轧制过程的板形控制情况,发现了其中存在的板形控制问题并提出了具体的改进措施。研究表明,为了使不锈钢和碳钢都能达到良好的凸度和平直度目标,需要合理确定两种产品的轧制工艺条件,使二者在板形控制上相互匹配。
Brief introduction of stainless steel 1780mm hot rolling production and shape control technology. The difference between stainless steel and carbon steel mixed rolling and centralized rolling is analyzed from the perspective of plate shape control. Based on the calculation results and the actual production results, the shape control of the typical stainless steel and carbon steel during the hybrid rolling process is analyzed. The existing problem of the shape control is found out and the concrete improvement measures are put forward. The research shows that in order to achieve the goal of good crowning and flatness of both stainless steel and carbon steel, the rolling process conditions of the two products need to be reasonably determined so that the two match each other in shape control.
