Stainless steel has high deformation resistance, generally twice that of ordinary carbon steel. During cold working, deformed martensite forms, causing a rapid work hardening rate and requiring greater rolling force and load.
Requirements Stainless Steel Cold Rolling Mill Should Meet
- Work rolls should be of small diameter as much as possible;
- The rolling mill should have high stiffness, both transversely and longitudinally.
- The roller system should maintain good stability in operation;
- Symmetry on both sides during reversible rolling;
- High tension and good tension and speed control ability;
- Good process lubrication and cooling system;
- Good roll gap adjustment and reaction speed;
- Good online convexity adjustment and reaction speed;
- Fully functional AGC (Automatic Gauge Control) and AFC (Automatic Flatness Control) control systems;
- The control function of the transmission system should be complete, stable, and energy-saving;
- Simple structure and easy to maintain.
