Overview of Intermediate Rolls
Intermediate rolls are critical components in rolling mills, positioned between work rolls and backup rolls to ensure stable force transmission and precise strip shape control. Although they do not directly contact the strip, they play a key role in distributing rolling force, supporting work roll performance, and maintaining consistent rolling results under demanding conditions.

How to Choose the Right Material
The selection depends on your mill type, rolled products, and performance priorities.
- For cost-effectiveness and resistance to rolling accidents:
If your mill operates under unstable conditions or produces standard products, MC3 or MC5 are economical and sufficient choices. Among them, MC5 is generally recommended as the standard option. - For high performance, long service life, and superior shape control:
For modern six-high cold rolling mills, silicon steel mills, or production lines with high surface quality requirements, semi high-speed steel has become the mainstream choice.
5H11 offers better wear resistance and spalling resistance than MC5, significantly extending roll life and improving mill efficiency, making it the preferred upgrade option.
5H12 further improves wear resistance compared to 5H11, making it ideal for rolling difficult-to-deform materials such as high-strength steel and stainless steel, or for stands highly sensitive to roll consumption. However, it also comes with higher cost and greater grinding difficulty.
