Abstract

The invention discloses a ceramic high manganese steel composite wear-resistant part casting method. The ceramic high manganese steel composite wear-resistant part casting method comprises the steps that ceramic powder is used for manufacturing ceramic particles which meet specifications; the ceramic particles and manganese steel powder are mixed by a binder to form a manganese steel powder-ceramic particle mixture; the manganese steel powder-ceramic particle mixture fills and is compacted into a predetermined mold for drying treatment, and ceramic core blocks are obtained; a wear-resistant part mold is filled with a predetermined number of ceramic core blocks, and high manganese steel metal liquid is casted into the wear-resistant part mold; and a casting in the wear-resistant part mold after the high-manganese steel metal liquid is injected is taken out for water toughening, and a ceramic high manganese steel composite wear-resistant part is obtained. The ceramic high manganese steelcomposite wear-resistant part casting method ensures the density of the ceramic core blocks in the compacted state by bonding the ceramic particles with the manganese steel powder with the same or similar specifications, and further, the high manganese steel molten metal is injected between the ceramic core blocks, the outer surfaces of the ceramic core blocks and through holes in the ceramic core blocks to ensure the wear resistance of the ceramic high manganese steel composite wear-resistant part after water toughening.

Description

technical field [0001] The invention belongs to the technical field of casting of wear-resistant parts, and relates to a method for casting ceramic high-manganese steel composite wear-resistant parts. Background technique [0002] Mill wear-resistant balls and wear-resistant parts are widely used in various ferrous and non-ferrous metal mine beneficiation plants, thermal power plants, cement plants, refractory plants and other industries to crush materials in ball mills. During the working process of the ball mill, wear-resistant balls are the main wearable parts, and their usage is large and costly. Therefore, the requirements for the wear resistance of the wear-resistant ball surface and the impact toughness of the wear-resistant ball are relatively high. Most industrial and mining enterprises at home and abroad use low-chromium balls, high-chromium balls or forged balls as grinding bodies. Among them, forged balls have less breakage, but high consumption and high deforma...
