1. Description:
MAΦ135/Φ350×350 Four-High Two-Stand Tandem Cold Rolling Mill
2. Main function:
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:
- The second type of cold rolling mill controls rolling speed and its
tension.
- The stable rolling is ensured.
- This machinery great guarantee the safety.
