Cast Steel Mill Liners Description:
1. Hardness: more than HRC50;
2. Impact Value: more than 50J;
3. Special heat-treatment process: Aiming at Cr-Mo alloy steel
castings with higher hardness & higher impact value & even hardness
distribution, we design a special quenching process, called
Double-media quenching technique with water-based quenching liquid.
4. Internal Quality: we check the internal quality with UT test;
5. External Quality: we check the external quality with MT test &
visual inspection;
6. Package: Packed by steel pallets.
7. We supplied the cast liners to Shanghai Heavy Machinery Plant &
Conch Cement Group.
In the recent 20 years, our liners have been widely used in large,
medium and small ball mills in Chinese power generation, mining,
cement, Chemical engineering and metallurgical industries and super
fine pulverizing equipments. It is the only recommended liner
product in the latest standard of the electric-power industry in
China.
