Abstract

The invention discloses a method for preparing a composite wear resistant lining plate. The method comprises the following steps: adopting alloy powder core bar materials of which the volume percentage is between 20 and 60 percent of the total volume of the lining plate, filling alloy powder in the core part of the alloy powder core bar materials, preset the alloy powder core bar materials in a lining plate casting mould, selecting base metal to be melted and poured in the lining plate casting mould, and cooling and demoulding the lining plate to obtain the composite wear resistant lining plate consisting of the alloy powder core bar materials and the base metal. The cylindrical hard phase of the composite wear resistant lining plate prepared by the method is generated by compounding in situ in a matrix, thus the composite wear resistant lining plate has the characteristics that segregation is not generated, the organization structure is even, the hard phase is difficult to fall off, the lining plate not only has the intensity and the toughness of the base metal but also has the high hardness and the high wear resistance of the hard phase, the service life is improved by an order of magnitude compared with the prior lining plate, the lining plate can bearing high impact force and strong wear at the same time, the technological parameter controllability of the preparation process is strong, and the price is low. The composite wear resistant lining plate can satisfy the applications under complex working conditions such as various wears, high impact and the like.

Description

technical field

[0001] The invention relates to mechanical equipment in the fields of general crushing, grinding, conveying, flotation and crushing, especially a method for preparing a composite wear-resistant lining. The composite wear-resistant lining prepared by the method is especially suitable for large-diameter, high-impact, Manufacture of parts for machinery and equipment in the field of grinding and crushing. Background technique

[0002] Lining plates on machinery such as crushing, milling, flotation, and conveying, which are widely used in coal, metallurgy, mining, electric power, building materials, refractory materials, and energy industries, are the main wear parts. At present, the lining plate materials used in various industries mainly include several single metal materials such as high manganese steel, multi-element low alloy steel, and chromium-based white cast iron. There is no hard carbide in high manganese steel, so the hardness is low. Only under high ...
