1. Brief Introduction
This unit produces the thickness of 2.0 ~ 4.5mm pickling hot-rolled coil, by if the road rolling, rolling into 0.20 to 1.5mm high-accuracy Cold rolled steel coilsl scale for the production of cold rolled steel volume 22.5 million tons / year production line of the cold rolling mill, using 6-hi UCM type single stand reversing cold mill, mill work roll is provided with a positive and negative bending and intermediate roll set is bending roll and tic, supporting a uncoiler, frame and are equipped with tension coiler, thickness gauge and laser velocimeter, tensiometer measurement etc., can achieve high tension rolling, ensure the thinner gauge products high and stable production.
