ANALYSIS AND CONTROL OF CONTUSION DEFECT OF HOT ROLLING STRIP STEEL
Author(s): 
Pages: 8-10
Year: Issue:  9
Journal: Hebei Metallurgy

Keyword:  热轧带钢挫伤板形卷取张力开卷张力加速度控制;
Abstract: 介绍了热轧带钢挫伤缺陷的形貌特征与分布规律;分析了薄规格产品平整挫伤缺陷产生的原因,认为带钢层与层之间存在间隙,在开卷张力作用下,层与层相对滑动,是造成平整挫伤的根本原因.通过优化板形、增加卷取张力和降低平整开卷张力加速度等措施,有效解决了平整挫伤问题.
