CN202110254375.0一种预判取向硅钢冷轧脆断发生的方法
本发明提出一种预判取向硅钢冷轧脆断发生的方法,将酸洗带头20‑30cm进行剪切取样,在取到的样板上面注明工作侧和传动侧;将取好的样板送至焊缝检测冲压机处,通过冲压机对样板进行冲压,根据不同钢带厚度,设定不同冲孔机压力,对样板进行冲压后,通过观察裂纹形貌,预判常化卷在冷轧轧制过程中是否会发生脆断,本发明使带钢在冷轧前能够制定相应的对策措施,从而降低冷轧断带所产生的损失。
电工钢热连轧宽度自适应模型优化及应用
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。 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 s...
