Ceramic/metal composite material wear-resistant lining plate and preparation method thereof

Abstract

The present invention relates to a ceramic / metal composite material wear-resistant lining plate and a preparation method thereof, and belongs to the technical field of materials. The ceramic / metal composite material wear-resistant lining plate comprises bainite-martensite complex-phase steel inlays, a porous ceramic / metal wear-resistant layer and a fixed base steel plate, wherein the porous ceramic / metal wear-resistant layer is provided with embedding holes, the bainite-martensite complex-phase steel inlays are fixedly embedded into the intermittent holes of the porous ceramic / metal wear-resistant layer, and the porous ceramic / metal wear-resistant layer is fixedly connected to the base steel plate. According to the present invention, the ceramic / metal composite material wear-resistant lining plate has advantages of good impact resistance, good wear resistance, long service life, convenient maintenance, simple production process and cost saving, can be adapted to different impact loads such as the high impact load, the medium impact load and the low impact load, and can effectively reduce the problems of the incapable provision of the characteristics of the material due to the inapparent high-manganese steel processing hardening effect and the great defect generated by the base body material due to the too high stress of the processed and hardened structure.

Description

technical field [0001] The invention relates to a ceramic / metal composite material wear-resistant liner and a preparation method thereof, belonging to the field of material technology. Background technique [0002] With the development of my country's metallurgical industry, ball mills used in mining, metallurgy, cement and other industries are developing towards large scale. The lining plate protecting the ball mill cylinder must have good wear resistance and good toughness to adapt Impact force under more complex working conditions. At present, linings made of high manganese steel and low-alloy wear-resistant steel are mostly used in China, but in actual working conditions, linings made of a single material cannot meet a wide range of impact loads, and their use has been greatly limited. When the high manganese steel is not used in a high impact state, the hard layer cannot be formed on the ball mill, and the work hardening cannot be fully exerted, resulting in unsatisfact...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the existing wear-resistant lining technology, the present invention provides a ceramic / metal composite wear-resistant lining, which adopts the mosaic combination of medium-carbon low-alloy silicon-manganese steel and matrix high-manganese steel to make the lining play a more excellent performance. Wear resistance. In the case of incomplete work hardening of high manganese steel, the bainite-martensite composite structure of inlaid medium-carbon low-alloy silicon-manganese steel has good comprehensive mechanical properties, and can resist the impact of abrasives on the surface of high manganese steel. High stress impact, at the same time, the ceramic / metal composite material of the wear-resistant layer has strong anti-wear performance, so the whole laminate shows good impact resistance and wear resistance
