Abstract

The invention discloses a method for producing ceramic- and metal-based composite wear-resistance liner plates, which comprises the following steps: selecting ceramic wear-resistance monomers, wherein the monomers have standard dimensions, a regular shape and a regular and symmetric equilaterally polygonal or round cross section respectively; selecting a high-temperature adhesive, wherein the main index is resistance to a temperature of 100 to 1,730 DEG C; adhering the ceramic wear-resistance monomers and casting mold cavities, wherein the inside surfaces of the mold cavities and the adhered surfaces of the wear-resistance monomers are both coated with the high-temperature adhesive uniformly by a blade, the ceramic wear-resistance monomers coated with the high-temperature adhesive are adhered on at specific positions of the inside surfaces of the mold cavities one by one, and the adhesive is solidified fully; and pouring molten high-temperature metal liquid into casting model, and cooling the casting molds. The plates combine the hardness of wear-resistance ceramic and the high obdurability of metals; and the method has the advantages of simple operation, high production efficiency, high product performance, stable quality and low manufacturing cost.

Description

technical field [0001] The invention relates to the field of wear-resistant materials, in particular to a production method of a composite wear-resistant liner. Background technique [0002] The wear-resistant liners of the material conveying systems in the mining, cement, metallurgy, electric power, chemical, port and other industries are the wear-resistant parts with huge consumption. At present, various types of high manganese steel, alloy steel, high chromium alloy cast iron and other metal wear-resistant lining plates are widely used in material conveying systems. [0003] Metal wear-resistant linings such as high manganese steel, alloy steel, and high-chromium alloy cast iron are produced by alloying or complex heat treatment processes to obtain certain wear resistance and comprehensive mechanical properties, which consume a large amount of rare metal resources and energy. At present, domestic research on metal matrix composite wear-resistant materials is limited to t...
