1. Brief Introduction
The 800 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 the change and system and fluid equipment (liquid pressure, equipment lubrication and lubrication technology such as) and organic composition of the instrument system, 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").
