Description

technical field [0001] The invention relates to the technical field of wear-resistant materials, in particular to a high-strength and low-wear wear-resistant ball for a ball mill and a preparation method thereof. Background technique [0002] As the crushing medium in the ball mill, the wear-resistant ball will directly affect the working efficiency and crushing effect of the ball mill. There are two main types of wear-resistant balls, one is chromium alloy cast iron balls, and the other is ductile iron balls. With the development of industry and the increase of various large ball mills, wear-resistant balls are easily damaged due to the complex working environment and consume a lot of energy, which affects the cost of ball mills. At present, wear-resistant balls still have the defects of low impact toughness, poor corrosion resistance, low strength, high wear, and low service life, which affect the working efficiency of wear-resistant balls.
