在收集现场酸液浓度化验数据的基础上,建立酸液密度、酸液电导率与盐酸浓度、铁离子浓度之间的线性回归关系,搭建酸液浓度在线检测系统,实现了冷轧酸洗机组酸液浓度实时在线检测,能够较好的指导机组酸液浓度的控制,最后提高带钢酸洗质量。
Based on the on-site acid concentration test data, a linear regression relationship between acid density, acid conductivity, hydrochloric acid concentration and iron ion concentration was established, an on-line acid concentration detection system was established, and a cold pickling unit Acid concentration online real-time detection, can better guide the unit acid concentration control, and finally improve the strip pickling quality.
