Application of High Chromium Cast Iron in Cement Mill
The manganese-aluminum composite high-chromium cast iron cement grinding roller liner is not ideal for hardenability and wear resistance for thick and large parts, and is only suitable for castings with an effective cross-section of 100mm-140mm. The roller liner with thick and large cross-section needs high-chromium cast iron with certain impact resistance, which is used for large-scale cement vertical mills.

Ball mill is the main equipment in the grinding process of cement, electric power, mining and other industries. Grinding ball is one of the main wearing parts of ball mill. The grinding ball must have both high wear resistance and high toughness. Its wear resistance plays an extremely important role in production. Therefore, it is extremely important to improve its hardness, impact resistance and wear resistance. In order to improve the density of cast iron balls and reduce hot cracking, Changzhi Iron and Steel (Group) Company improved the chemical composition and uniformity of cast iron balls by adding different rare earth elements. And successfully used in the ball mill for the production of cement, significantly improved the wear resistance of the grinding ball.
