 Features and applications
1. Suitable for mild steel, stainless steel, and special steel.
2. Transmission method: working rollers transmission and supporting rollers transmission. Control methods: common electric pressing down and hydraulic pressing down through AGC system.
3. Equipped with hydraulic bending 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, easily 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.
 Components
Entry tension reel(unloading car) → front device → four-high rolling mill → rear device → exit tension reel(unloading car)etc.Uncoiler and head straightening machine could be equipped as per user’s needs.
