Composite lining board and its manufacturing method

Abstract

The invention discloses a composite lining board and a manufacturing method thereof, comprising a base body and a wear-resistant plate, the lower end of the wear-resistant plate is fixed on the upper end surface of the base body, and the wear-resistant plate includes several first wear-resistant layers and several second wear-resistant layers. Wear-resistant layer, the first wear-resistant layer and the second wear-resistant layer are alternately arranged up and down, the first wear-resistant layer includes the first impact-resistant mesh layer and the first wear-resistant block, and the first impact-resistant mesh layer is evenly arranged A plurality of first through holes, the first through holes penetrate the first impact-resistant mesh layer in the direction perpendicular to the upper end surface of the base body, one first through hole corresponds to filling and fixing a first wear-resistant block, and the first wear-resistant block Corresponding to the shape of the through hole, the second wear-resistant layer includes a second impact-resistant mesh layer and a second wear-resistant block. The second wear-resistant layer is provided with a plurality of second through holes, and the second through holes are perpendicular to the substrate. The direction of the end face penetrates through the second impact-resistant mesh layer, and a second through hole is correspondingly filled and fixed with a second wear-resistant block. The composite liner is wear-resistant and impact-resistant, and has a long 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
