Irreverisible Continuous 4 Hi Steel Cold Rolling Mill 170m / Min High Precision

1. Description of goods:

High Precision Irreverisible Continuous 4-Hi Steel Cold Rolling Mill

Cold rolling mill use a special cold forming process which is both cost-efficient and indispensable for many applications. It is used to improve roundness, stress homogeneity, and surface roughness of the tubes. The tolerance of finished tubes is about ±0.05mmCold rolling mill is devided into manual operate, automatic feeding and fully automatic and high speed type, the fully automatic type is high speed and continuous cold rolling type.

2. Introduction:
Due to different numbers of rollers, the metal coil cold rolling mill is divided into 2 Hi, 4 Hi, 6 Hi, and 12 Hi AGC.
This 4-Hi cold rolling mill, one of metal coil cold rolling mill, is made from good quality raw material. A four-high cold rolling mill has four rolls, two small and two large. The two small rolls are work rolls in contact with metal coil, and the two large ones are backup rolls which contact the back side of the small work rolls. At the same time, we are upgrading with the latest technological equipments when producing this cold rolling mill.

3.Process Flow(as reference)

Loading → decoiling →two roller pinch →shearing→ welding (manual welding machine provied by the user) → ground looper →five roller tension roller→ vertical edger guide → F1 four-high mill (thickness measurement, tension measurement) → F2 four-high mill (thickness measurement)→Exit platform (de-oiling,thickness measurement)→shearing→coiling machine→unloading.

4. Advantages:
1. The second type of cold rolling mill controls rolling speed and its tension.
2. The stable rolling is ensured.
3. This machinery greatly guarantee the safety.
