Stainless Steel Four High Rolling Mill , Electric Reversible Rolling Mill
I. Function and characteristics:
1. Suitable for mild steel, stainless steel, and special steel.
2. transmission method: working roll transmission and supporting roll transmission. control methods: common electric pressure down and hydraulic pressure down through AGC system.
3. Equipped with hydraulic bending installations of working rollers which can fast adjust the gibbous degree of rollers to change the distribution of touching pressure between rollers in order to control the plate form.
4. With simple construction, easy maintenance, and less investment.
5. It is equipped with AGC system to get high precision, which is especially suitable for rolling high precision requirements of cold rolled strips.
II. technical flow:
Front coiler(unloading car)--front device--4-roller main mill--rear evice--rear coiler(unloading car). The uncoiler and leveller machine to be equipped or not will be decided by user.
