High Speed Four Stand 800mm Continuous Cold Rolling Mill line used for make pipe Q195,Q215,Q235

1. Description of goods:

Four stands cold rolling mill machine with Full mechanical press down control system for Q195,Q215,Q235 with high speed

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.
The 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 rolls 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. Features: 

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