Generally, there are four types of materials used in mill roller tyre and table segment.
- High chrome white iron. The most widely used material for mill roller tyre and table segment is high chrome white iron, especially 20%Cr-Mo/G-X260CrMoNi20 2 1.
- Ni-Hard 4/Ni-hard IV. Ni-hard material are normally used when the roller tyre and table segment are very thick. In order to avoid cracking during heat treatment, Ni-Hard material is generally chosen to fit the purpose.
- Hardfacing layer+Steel base. Hardfacing layer+steel base is generally used for mill roller tyre and table segment for its capability of repairment after long operation hours. Welding of the hardfacing layer needs to be performed very carefully to avoid peeling off during operation.
- Ceramic composite material. Ceramic composite material is widely known for its high hardness for mill roller tyre and table segment. It has longer life-time than the other three types of material. However, the cost of ceramic composite material is quite high compared to others.
