Four Roller Four High 4 Hi Cold Rolling Mill Line
4Hi Cold Rolling Mill is frequently seen in steel strip processing plant, for the 4high mill has many advantages.
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.
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.
4Hi Cold Mill Features:
- suitable for rolling carbon steel, stainless steel, special steel, copper, aluminum strips, etc
- two work rollers and two backup rollers, drive on work roller or on backup roller
- press-down type: normal double grades worm gear & screw rod press down or hydraulic AGC
- Hydrualic work roller bending: can adjust roller convex degree and contact between rollers easily, thus output good flatness of CR strips.
- Simple structure of less components, easy to be adjusted and maintained.
- Hydraulic AGC 4Hi mill is high precision
- DC motors are controlled by 6RA80 series digital DC driver,the mill line is controlled by PLC
