4Hi Four Roller Cold Rolling Mill is frequently seen in steel strip processing plant, for the 4high Rolling mill has many advantages, 4hi rolling mill is simple in structure, only four rollers are 1 pair of work rollers and 1 pair of support rollers, easy to operate and maintain, widely used for Steel strip rough rolling, tandem rolling, copper strip rolling, aluminum foil rolling, stainless steel strip rolling. Therefore, we should know every sides of the 4High Cold Rolling Mill

Metal plate Rolling Mill reduce metal plate thickness uniformly by rolling, also called “plate thickness reducing mill”.

The rolling tools are cylindrical rollers, in line with composition and structure of roller system which are for metal plates of different materials uniform thickness reducing, we see 2High, 4High, 6High, 8High, 12High, 20High Rolling mills.

Generally speaking, 2High Rolling mill usually for rough rolling stage, the most frequently seen is 4High and Six High Mill. The high precision thin sheet rolling will require 8High and more rollers mill.

We design rolling mill in accordance with customers raw metal materials, finished plate specification and tonnage production of rolled plates, huge production needs tandem rolling mill, interim annealing probably is required.

Composition of 4High cold rolling mill:

The automatic 4 High cold rolling mill,either one way or reversible, is composed of decoiler(recoiler), entry processing table, 4high rolling mill, exit processing table, recoiler. The rolling mill model is mainly categorized by mill width, the wider, the mill model bigger.
