The classification of wear-resistant steel balls can be divided into three categories: hot-rolled steel balls, forged steel balls and cast steel balls according to different production processes. Cast steel balls, according to the content of chromium in the ingredients, can be divided into high-chromium alloy cast steel balls, medium-chromium alloy cast steel balls and low-chromium alloy cast steel balls. The medium and low chromium cast steel balls have poor wear resistance and high fracture rate. Although the price is low, the wear is high and the overall cost performance is low, so it is not recommended. High-chromium alloy cast steel ball, which has high hardness due to the addition of chromium, is a high-quality wear-resistant material and has been widely used in dry ball mills such as cement and new building materials.
