Low-alloy fused alumina zirconia ceramic ball composite material

Abstract

The invention discloses a low-alloy fused alumina zirconia ceramic ball composite material which is characterized by comprising the following components in parts by weight: 5-10 parts of vanadium iron powder, 3-9 parts of high-temperature-resistant adhesive, 15-30 parts of zirconium dioxide, 1-8 parts of redispersible latex powder, 18-30 parts of ferric sodium pyrophosphate, 11-19 parts of kaolin, 11-25 parts of porcelain stone, 5-9 parts of sericite, 3-9 parts of reactive resin adhesive, 0.5-1.2 parts of antimony oxide, 1-2 parts of copper oxide, 35-60 parts of sodium silicate binder, 10-28 parts of manganese oxide, 3-13 parts of titanium oxide and 50-75 parts of fused alumina zirconia ceramic ball. The composite material avoids the problem of incomplete functions in single low-alloy steel, and the cost of the fused alumina zirconia ceramic ball is equivalent to that of the low-alloy steel under the condition of the same volume, thereby greatly prolonging the service life of the product on the premise of not increasing the product cost, and bringing in economic benefit to the production enterprise. The low-alloy steel base material around the ceramic ball tightly fixes the ceramic ball, thereby preventing the ceramic ball from falling; and the material surface is made of alloy, so the appearance quality is not influenced, and thus, quick mass production can be implemented.

Description

technical field [0001] The invention relates to a low-alloy zirconium corundum ceramic ball composite material. Background technique [0002] The machinery used for mining in mines consumes a lot of wear and tear, and the amount of metal wear-resistant materials consumed by abrasive wear alone reaches more than 3 million tons every year. The economic loss is more than 100 billion yuan. The main reason is that most of the working parts are made of metal, and the working objects faced in mines are non-metals with high hardness. The hardness of the former is much lower than that of the latter. It needs to be replaced in a few days, resulting in increased costs and downtime losses. Complex working objects and harsh working conditions require that the material of the processed parts should be corresponding to or even higher than the working object in terms of hardness. It is difficult to adapt to a single metal alloy material, especially the striking surface of the working part...
