Various specifications of forged steel grinding balls are produced by advanced rotary-rolling forging steel ball technology. The raw materials used are high-quality special steel. The round steel is heated to 800-900 ° C, and the ball is formed into a ball through a line rolling mill. The advanced post-treatment technology makes the forged steel grinding balls have lower wear and higher hardness.
At the same time, it has high toughness and extremely low breaking rate. It is stable in long-term use in various mines, various grinding media, various specifications of grinding machines and various harsh environments. Such forged steel grinding balls help to increase labor productivity, and the economic and social benefits are remarkable, and its excellent performance is difficult to achieve with other balls.
Compared with other similar products, forged steel grinding balls have high hardness, high wear resistance and high overall hardness; high toughness, toughness ≥17J/cm2; strong resistance to flaking and crushing, and the number of falling ball impacts is 100,000-200,000 times. Without breaking, the actual breaking rate is <1%. According to the customer's quality requirements for forged steel grinding balls, the qualified rate of forged steel grinding balls is 100%.
