Shougang steel ball has five series of products with diameter from 10-150mm, including super high chrome grinding media ball, cr:20%-30%; high chrome grinding media ball, cr:10%-20%; medium chrome grinding media ball, cr:3%-7%; low chrome grinding media ball, cr:1%-3%; and multi-component alloy grinding media ball, cr:10%-30%. The products are widely used in mental mining industry, cement plant, coal slurry thermal power, chemical industry, ceramic coatings, light industry paper, powder preparation and ultra-fine deep processing of magnetic materials and other industries. The products is high hardness, good toughness, lowest breakage, good wear resistance; in the process of using the ball , surface hardness as well as the wear resistance will be further improved and can improve the mill production capacity, the cement specific surface area and concentrate recovery rate.
The wear resistance of high chrome cast iron balls are 1.8 times greater than common forged steel balls. The grinding media balls for mines and cement industry have a lower wearing rate, could increase the efficiency of mill grinding and processing, the gradation of grinding ball in the mill is stable, also can increase the output production and assurance of the mineral concentrate quality. Cement building materials with high chromium cast iron ball, with high temperature resistance, abrasion, low broken rate and extend the ball with the cycle, reduce the labor intensity of workers, especially can greatly reduce the number of balls and complement.
High hardness:58-65 hrc,
Good impact toughness: more than 4j/cm2,
Low broken rate: less than 1%,
Good wear-resistanct: wearing rate of high cr cast ball is 30-50g/ton in cement industry, 350-430 grams in gold mines and even lower in some iron mines.
