将带钢的连续酸洗机组与冷连轧机连接起来生产冷轧板的想法由来已久,但经历了近三十年,解决了诸多技术问题之后才得以实现。 1.酸洗—冷轧联合生产的技术基础 1.1高效新型酸洗工艺 60年代前,冷轧板生产多采用硫酸酸洗,生产效率低,酸洗效果不理想。60年代初,解决了盐酸回收问题之后,大型连续酸洗机组采用酸洗能力强的盐酸作为酸洗介
The idea of connecting strip continuous pickling units with tandem cold rolling mills to produce cold-rolled plates has been around for a long time, but it has been practiced for nearly three decades after many technical problems have been solved. 1. pickling - Cold Rolling joint production technology 1.1 efficient new pickling process 60 years ago, cold-rolled sheet production using sulfuric acid pickling, low production efficiency, pickling effect is not satisfactory. The early 60s, to solve the problem of hydrochloric acid recovery, the large continuous pickling unit pickling capacity of hydrochloric acid as a pickling medium
