Product Details
Alloy Steel Mill Lining 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.
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.
