在冶金工厂的扩建改造中,酸洗厂房的改造和维修仍然是一个比较困难的问题。目前钢管、冷轧钢材的生产过程中仍然采用酸洗工艺,清理钢材内外表面氧化物。因此,每个轧钢、轧管车间一般部设置酸洗工段。尤其冷轧钢管车间钢管的酸洗频繁,产量很高,规模较大。酸洗虽然是在生产中不可少的一个工序,但在整个生产过程中只是一个辅助工段。因此往往对酸洗所产生的危害、污染认识不足,酸洗设备和工艺手段都非常简陋。近年来,酸洗对厂房的危害日趋严重,影响生产和安全。 In the expansion and reconstruction of the metallurgical plant, the reform and maintenance of the pickling plant is still a difficult problem. Currently, pickling processes are still used in the production process of steel pipes and cold-rolled steels to clean the surface oxides inside and outside the steel. Therefore, the pickling section is set in the general department of each rolling mill and rolling mill. In particular, the cold-rolled steel pipe workshop is frequently pickled and has a high output and a large scale. Although pickling is an indispensable process in production, it is only an auxiliary section during the entire production process. Therefore, there is often insufficient understanding of the hazards and pollution caused by pickling, and the pickling equipment and process methods are very simple. In recent years, acid washing has become more and more serious and affected production and safety.
