连续酸洗机组生产厚料通板问题分析及改进

Analysis and Improvement of Thick Plate Production in Continuous Pickling Unit

针对连续酸洗机组生产厚料发生的划伤和卸卷抽芯问题进行分析,通过增加酸槽出口4#张力辊组传动装置、改变卷筒结构形式、优化酸洗工艺段张力参数设定、卸卷带尾定位控制方式等措施,解决了机组生产厚料划伤和抽芯问题,并取得了较好效果。

This paper analyzes the causes of the scratches and core-pulling problems of the continuous pickling unit in the production of thick strip.by adding the driving device of 4~#tension roller set at the acid tank outlet,changing the drum structure,optimizing the tension parameter setting in the pickling process section,and the positioning control method of the strip tail,the problems of the thick strip scratches and core-pulling in the production of the unit are basically solved,and obtains good results.
