摘要/Abstract

摘要： 某厂对电工钢的轧制策略进行了优化，粗轧道次由“1+5”改为“1+3”。在优化后的生产过程中，每次变换钢种，烫辊材就会出现窄尺现象，而紧随其后的电工钢板则出现超宽现象。文中针对该问题，介绍了宽度设定模型和宽度自适应模型的原理，阐述了该问题出现的原因及解决方案，并通过对宽度自适应模型的应用研究及优化攻关，有效地解决了问题，大幅提升了实物质量，降低了宽度封锁率。

Abstract: The rolling strategy of electrical steel was optimized in a factory, and the rough rolling pass was changed from “1+5” to “1+3”. Subsequently, the following problems were occurred in the production process: when the steel grade changed, the roasting roller steel before the electrical steel appeared the narrow width phenomenon, and then the electrical steel appeared the ultrawide phenomenon. This paper introduced the principle of width setting model and width adaptive model, and expounded the causes and solutions of this problem. In the end, the problem was solved effectively, the product quality was greatly improved and the width blocking rate was also reduced.
