How to Choose the Right Material for Work Rolls
Rolling Type (Cold Rolling vs. Hot Rolling)
- Cold Rolling:
Focus on wear resistance at room temperature and resistance to rolling accidents. MC5 is a reliable choice; for longer service life, M2 or YM5 can be selected. For very small sizes or applications requiring extremely high wear resistance, Cr12Mo1V1 can be considered. - Hot Rolling:
Red hardness and resistance to thermal fatigue are critical. High-speed steel grades (M2, YM5, YM8) are the preferred choice. M2 or YM5 are suitable for entry stands, while YM8 is recommended for final stands where surface quality requirements are extremely high.
Applications in Rolling Mills
These work rolls are widely used in cold rolling and hot rolling finishing mills, suitable for processing stainless steel, silicon steel, carbon steel, and other metal materials across various industries.
Conclusion:
The correct selection should be based on a comprehensive evaluation of the rolling process, rolled material, cost budget, and equipment maintenance capability.
