Composite lining plate and manufacturing method thereof

Abstract

The invention discloses a composite lining plate and a manufacturing method thereof. The composite lining plate comprises a base body and a wear-resisting plate, the lower end of the wear-resisting plate is fixed to the upper end face of the base, the wear-resisting plate comprises a plurality of first wear-resisting layers and a plurality of second wear-resisting layers, the first wear-resistinglayers and the second wear-resisting layers are alternately arranged up and down, each first wear-resisting layer comprises a first impact-resistant net-shaped layer and first wear-resisting blocks, aplurality of first through holes are uniformly formed in the first impact-resistant net-shaped layers, the first through holes penetrate through the first impact-resistant net-shaped layers in the direction perpendicular to the upper end surface of the base body, one first through hole is correspondingly filled and fixed with one first wear-resisting block, the first wear-resisting block corresponds to the through hole in shape, each second wear-resisting layer comprises a second impact-resistant net-shaped layer and second wear-resisting blocks, a plurality of second through holes are formedin the second wear-resisting layer, the second through holes penetrate through the second impact-resistant net-shaped layer in the direction perpendicular to the upper end face of the base body, onesecond through hole is correspondingly filled with one second wear-resisting block in a fixed mode. The composite lining plate is resistant to wear and impact and long in service life.

Description

technical field [0001] The invention relates to the technical field of wear-resistant lining boards, in particular to a composite lining board and a manufacturing method thereof. Background technique [0002] In the mechanical equipment used in mining, cutting tools, underground engineering and other fields, due to the long-term impact of sand and ore, it is easy to cause wear and failure of the workpiece, affect its service life, and cause material waste. In recent years, due to the immaturity of wear-resistant technology and equipment in my country, the wear-resistant performance of manufactured materials is generally lower than that of foreign countries, and the service life is short. Therefore, it has become an inevitable trend to improve the wear-resistant performance of materials and the service life of workpieces.

AI Technical Summary

Problems solved by technology

[0003] Ceramic reinforced metal matrix composites are a new type of material, in which WC particles have the characteristics of high hardness and high melting point. Using WC ceramic particles to reinforce steel-based liners has become a feasible and reliable method for preparing wear-resistant layers of parts, but in In the prior art, WC ceramic particles are often directly used as the wear-resistant layer, which is easily detached during use and has poor impact resistance
