1、Overview:
This 850mm four/six high five stand tandem cold rolling mill is used to produce Q195, Q235, SPHC, SPHD, SPHE and other pickling hot rolling strip rolls. The raw material used in the production line is hot rolled steel strip after acid pickling in accordance with national standards. After discharging by the un-coiler, it passes through leveler, floor looper and entrance S roller and enters the five-stand continuous rolling mill for rolling. Finally, it is rolled into the cold-rolled qualified steel strip with the required thickness, and the strip is rolled and packed by the winding machine.
