Description

technical field [0001] The invention relates to the technical field of wear-resistant materials, in particular to a wear-resistant steel forging for a ball mill and a preparation method thereof. Background technique [0002] Ball mill is widely used in cement, electric power, mineral processing, building materials and other industries. Steel forging, as the grinding material medium in the ball mill, has been subjected to collision and friction between steel forgings and between steel forging and materials for a long time. Wear resistance and mechanical properties have certain requirements. The existing steel forgings for ball mills have problems of insufficient wear resistance and mechanical properties, which affect the service life and grinding effect of the steel forgings. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a wear-resistant steel forging for ball mills and its preparati...
