Cold Rolling Stainless Steel - Requirements and Comparisons

Cold Rolling Stainless Steel – Requirements and Comparisons

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

  1. Work rolls should be of small diameter as much as possible;
  2. The rolling mill should have high stiffness, both transversely and longitudinally.
  3. The roller system should maintain good stability in operation;
  4. Symmetry on both sides during reversible rolling;
  5. High tension and good tension and speed control ability;
  6. Good process lubrication and cooling system;
  7. Good roll gap adjustment and reaction speed;
  8. Good online convexity adjustment and reaction speed;
  9. Fully functional AGC (Automatic Gauge Control) and AFC (Automatic Flatness Control) control systems;
  10. The control function of the transmission system should be complete, stable, and energy-saving;
  11. Simple structure and easy to maintain.
