1. Description of goods:
MAΦ140/Φ450×450 Two stand cold rolling mill machine with Disc storage looper for Q195,Q215,Q235
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. Advantages:
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.
Hydraulic AGC System
Functions: AGC (hydraulic control of press-down seam), AFC (constant rolling force control), pre-control of thickness gauge, monitoring, etc
Precision:
Stable rolling: 0.3mm ±4.5μm; 0.5-0.8mm ±7μm
Speed-up and speed-down rolling: 2%h≤±10μm
