Abstract

The invention discloses a preparation method of a wear-resistant ball for cement. The preparation method comprises the following step that a wear-resistant ball workblank is obtained through pouring, wherein a wear-resistant ball workblank alloy comprises, by weight percentage, 3.2-3.4% of C, 0.9-1.2% of Si, 0.4-0.8% of Mn, 0.002-0.01% of P, 0.005-0.013% of S, 1.4-1.7% of Cr, 0.14-0.18% of RE, 0.15-0.35% of W, 0.04-0.12% of V, 1.25-1.45% of Ni, 0.03-0.06% of Te, 0.02-0.08% of Cu and the balance iron. According to the preparation method of the wear-resistant ball, internal defects of a material are effectively eliminated; wear resistance and fatigue strength of the wear-resistant ball are improved; meanwhile, the preparation method has the beneficial effects of being free of oxidation, free of decarburization, free of element depletion and the like; and heat treatment deformation of the wear-resistant ball can be reduced.

Description

technical field [0001] The invention relates to the field of preparation of wear-resistant balls, in particular to a preparation method of wear-resistant balls for cement building materials. Background technique [0002] Wear-resistant balls are widely used in ball mills in metallurgical mines, cement building materials, thermal power generation, flue gas desulfurization, magnetic materials, chemicals, coal water slurry, pellets, slag, ultrafine powder, fly ash, calcium carbonate, quartz sand, etc. . The current wear-resistant balls have disadvantages such as poor wear resistance and easy damage. Further research and development and exploration are needed for the anti-rust performance and wear resistance of wear-resistant balls. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing wear-resistant balls for cement building materials. The internal defects of the material are effectively eliminated, and the wear resi...
