6 Hi Reversible Cold Rolling Mill Machine Width 850mm
The 6Hi reversible cold rolling mill machine with width 850mm can work with the pikling hot rolled coil.
It can roll the thickness of 1.2mm -4.0mm into 0.18mm-1.2mm. The working width can be from 500mm-750mm.
1. Brief Introduction
The 850 six roller reversible cold rolling mill mainly consists of uncoiler, coil car, at the beginning of the straightening machine, left roll machine, coil discharging equipment, machine device, 850mm six roller reversible cold rolling mill working machine, machine device, scroll right take machine, unloading volume device, supporting roller system and fluid equipment (hydraulic, lubrication, lubrication, etc. ) and instrument system organic composition, electrical, instrumentation, integration of the automation of complete sets of equipment. This work will be used in the form of the national equipment engineering contract ("turnkey").
