Coil Width 200mm Two Stands 150m/Min 4hi Cold Rolling Mill For Carbon Steel
1. Description of goods:
A continuous rolling mill is constructed by arranging driven horizontal rolling mills and undriven vertical rolling mills alternately and determining the values of the thickness of the rolled material between adjacent stands, the interaxial distance between work rolls, and the diameter of the work roll to satisfy predetermined relationships.
2. Mill process:
Loading → unwinding → pinch
↓
Unloading ← mill four roller cold rolling mill roll left and right roll mill → unloading.
3. Techncial parameter:
| Work rollers (mm) | φ175 |
| Roller length (mm) | 350 |
| Rolling force (Tons) | 240T |
| Input thickness (mm) | 3.0×240mm |
| Finished thickness (mm) | 1.8×240mm |
| Width(mm) | 240 |
| Rolling speed (m/min) | 150 |
| Main motor (KW) | 280KW |
| Rotation speed: | 750-1600r/min |
