Acid Picking line:The pickling production line is a very important process in the cold-rolled strip production process. The purpose is to remove the iron oxide from the strip surface, adjust the roll weight, cut the crack edge, provide the qualified raw material for the rolling; according to process, pickling is divided into push-pull pickling and continuous pickling.
works. These are:a continuous pickling line/tan-dem cold mill with five mill stands of six-high design, one continuous hot-dip galvanizing line as well as one two-stand DCR cold rolling mill (DCR = Double Cold Reduction). The combined pickling line/tandem cold mill is a prime example of the newly developed high-tech mills and is No.127 Used 1250mm 6Hi Cold Rolling MillCR No.127 Used 1250mm 6Hi Cold Rolling Mill.
