1450 4hi Reversible Single Stand Cold Rolling Mill/Production Line/Machine/Equipment

1. Brief Introduction of 1450 4hi reversible single stand  cold rolling mill/production line/machine/equipmentThe production of this unit is to roll hot rolled coils with the thickness of 1.5~5.3mm into high precision cold rolled coils with the thickness of 0.2~2.0mm through several time of rolling. The scale of the cold rolling production line is a production of 250 thousand tons of cold rolled steel coils per year. It adopts the single-stand 4-roll reversible cold rolling mill. The work roll of the rolling mill is equipped with positive and negative bending. The uncoiler is equipped. Both front and rear frames are equipped with coiler, thickness gauge, laser velocimeter etc., which can realize large tension rolling and guarantee high-speed and stable production with specified thinness.2.
