Embodiment Construction

[0015] A production process of a high-chromium alloy ceramic particle composite grid, comprising the following steps in sequence:

[0016] Melt the high chromium alloy and place it in the ladle, add sintered and crushed alumina and / or zirconia particles with a particle size of 80 to 100 mesh in the ladle, stir and mix, inject the mixture into the grid sand mold, and then Cool and take it out to obtain a composite mesh 1 of high chromium alloy ceramic particles.

[0017] The added amount of the alumina and / or zirconia particles is 30%-40% by volume.

[0018] The alumina and zirconia particles are particles with a content of 95% or 99%.

[0019] The specification of the grid sand mold is to make the thickness of the composite grid to be 15-20mm.

Abstract

The invention discloses a production process of high-chromium alloy ceramic particle composite grids, which comprises the following steps of: melting high-chromium alloy, and then, putting the melted high-chromium alloy into steel ladle; adding sintered and crushed aluminum oxide and/or zirconium oxide particles of which the particle diameters are 80-100 meshes into the steel ladle and stirring and mixing, and then, injecting the mixed liquid into grid sand molds; and cooling and taking out grids to obtain high-chromium alloy ceramic particle composite grids. In the invention, the wear resistance of the ceramic particle materials and the mechanical properties of the high-chromium alloy are organically combined; the produced composite materials have high hardness, shock resistance and wear resistance, are latticed, can be prepared into tapered, cambered and circular grids in various shape sizes, and can also be prepared into grids in other shapes; and the super-hard latticed composites are cast for the second time to form required wear resistant products to achieve the anti-wear effect of mechanical equipment.

Description

Technical field: [0001] The invention relates to a production process of a composite framework material for crushing equipment and a grinding machine. Background technique: [0002] The surface wear resistance of the existing crushing equipment and grinding machinery is not ideal, which affects the service life of the equipment and production stability. Invention content: [0003] The purpose of the present invention is to provide a production process of high chromium alloy ceramic particle composite mesh with high hardness and which can improve or prolong the service life of equipment. [0004] Technical solution of the present invention is: [0005] A production process of a high-chromium alloy ceramic particle composite grid is characterized in that it includes the following steps in sequence: [0006] Melt the high chromium alloy and place it in the ladle, add sintered and crushed alumina and / or zirconia particles with a particle size of 80 to 100 mesh in the ladle, ...
