How to choose and optimize the material of 6Hi rolling mill and temper mill?
The material selection and optimization of the work rolls for 6Hi rolling mill and 6Hi temper mill are basically the same as the selection of the 4Hi rolling mill and temper mill. Some users have found that the surface roughness of the work rolls with 5% Cr forged steel changed rapidly when rolling high-grade car plates. At this time, forged semi-high-speed steel materials can be used. But because the forged semi-high-speed steel materials are expensive, you must compare the performance & price then decide.
