摘要
热轧原卷的头尾部宽度超宽问题,是国内各钢厂面临的普遍生产难点。本文主要讲述了模型人员通过现场数据分析和生产跟踪调试,独立自主开发了一套粗轧立辊AFC和SIN曲线短行程控制模型,提高了热轧电工钢头尾宽度质量,有效降低了热轧原料卷头尾宽度高点和超宽范围,从而减少因带钢头尾超宽导致刮蹭下工序轧机导向辊、造成破边甚至断带事故的发生率。该技术对电工钢产线提高成材率具有参考意义。
The problem of excessive width at the head and tail of hot-rolled electrical steel coils is a common production difficulty faced by domestic steel mills.This article mainly described the independent development of a rough rolling vertical roll AFC and SIN curve short stroke control model by model personnel through on-site data analysis and production tracking debugging,which improved the quality of the head and tail width of hot-rolled electrical steel,effectively reduced the high point and ultra wide range of the head and tail width of hot-rolled raw material coils,and thus reduced the incidence of edge breakage or even strip breakage accidents caused by scratching the guide rollers of the rolling mill in the next process due to the ultra wide head and tail of the strip steel.This technology is of reference significance for improving the yield of electrical steel production lines.
