由于薄板坯连铸连轧工艺的特殊性和超薄带钢轧制的特点,在短流程生产线轧制的超薄带钢表面易产生硌印缺陷,特别是低碳钢和一些对表面要求较高的钢种。对此从产生硌印缺陷的各种原因进行了详细的分析,并提出了相对应的控制策略和解决方法,在本钢短流程生产线获得了较好的效果。 Due to the particularity of the thin slab continuous casting and rolling process and the characteristics of the ultra-thin strip rolling, defects in the printing are likely to occur on the surface of the ultra-thin strip rolled by the short-flow production line, in particular, mild steel and some surface- High steel. In this paper, a detailed analysis is made on the various causes of defects in printing and printing, corresponding control strategies and solutions are proposed, and good results are obtained in the short-run production line of Benxi Iron and Steel.
