Tandem continuous cold rolling mill introduction
Reversible cold rolling mill can get different finished thickness by to-and-fro multiple rolling process, it is flexible and precise. When steel plants want to produce huge production of cold rolled steel plates, reversible rolling mill multiple to-and-fro rolling can not satisfy, tandem continuous one way cold rolling mill is suitable for the situation.
Tandem continuous cold rolling mill make cold rolled coils (CRC) on one direction rolling process by passing through multiple rolling mill heads(2 heads, 3 heads, 4 heads, 5 heads, 6 heads). We design the tandem cold rolling mill line according to client’s requirements on metal material, input thickness, output thickness, annual production, and properties of finished plate.
Ø185×700/Ø600×650 Three Heads Tandem Cold rolling Mill, 210m/min
