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. Technical specification
