Six Roller Six High 6 Hi Cold Rolling Mill Line For Metal Strip

Six high cold mill is a type of fine rolling mill to make precision finished CR strips. 6High Cold Mills have different models, bigger or smaller, for wider or narrower, harder or softer metal strips. The six high rollers, one pair of work rollers, one pair of middle rollers and one pair of backup rollers, are tailored to suit different materials of different applications, the six rollers arrangement in structure, diameter and drive has different options to consider.

• The pair of middle rollers can be hydraulically transferred in axial direction to support work roller as per steel strip width,
• the middle rollers a little deviate from upright direction to back support work roller to bear deflection from pulling tension.
• The 6Hi rolling mill usually is reversible type to outcome high precision cold rolled metal strips
• Process of a reversible 6hi rolling mill line: loading car, straightener, recoiler(unloading car), entry processing table, 6hi mill,exit processing table, recoiler(unloading car)

6Hi mill Characters

1. suitable for rolling normal carbon steel, stainless steel, special steel,copper strips, esp. for high precision rolling of wide and thin strip.
2. the work roller bending mechanism and middle roller axial transfer mechanism can fast adjust work roller convexity and improve the distribution of roller contact, thus well control strip flatness and roller convex degree.
3. Strip shape is flat, uniform and stable, improve the strip edge thinner or crack defects.
4. work roller diameter can be smaller, increase each pass gauge reduction and total gauge reduction
5. work roller can be flat type, reducing roller consumption and spare.
6. Hydraulic AGC 6High cold rolling mill is high precision for thin & wide strip rolling.
