Rolling mill rolls is an important consuming part that determines the efficiency and quality of rolling mill. It is an important part of rolling mill.So what factors do we usually need to take into account when making rolls?
1. The rolling mill rolls must have good bite quality, so the thickness of the blank should be large.
2. The selected material of roll rolls must have good thermal cracking resistance and thermal fatigue resistance;
3.rolling mill rolls the material is large in diameter, long in length and high in rolling force
4. Roll rolls The material is required to have high fracture resistance and high strength.
5. Because the roughing and finishing rolling are completed in the same frame, is necessary to take into account the large thickness and small width of the roughing parts of roll rolls
