 6hi reversible cold rolling mill coil width 1450mm for steel sheet or coil 


production capacity
1450 6-roll reversible cold rolling unit is the cold rolling production line with designed annual output of 225 thousand tons and adopts UCM-type single-stand mill.
1. Its usage
To roll high quality cold rolled steel coil( plain carbon steel)
2. Brief  Introduction:
The production of this unit is to roll hot rolled coils with the thickness of 2.0~4.5mm into high precision cold rolled coils with the thickness of 0.18~1.5mm through several time of rolling.

The production capacity of the cold rolling production line is a production of 225 thousand tons of cold rolled steel coils per year.

It adopts the UCM-type single-stand 6-roll reversible cold rolling mill. The work roll of the rolling mill is equipped with positive and negative bending. The intermediate roll is equipped with positive bending and twitch. The un-coiler 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.
