Embodiment

[0057] A grinding roller wear-resistant part used in a thermal power station is manufactured by the above method. The part is manufactured by the method of centrifugal casting. The manufacturing process includes the preparation of mineral particle clay blocks, the introduction of the block and the preparation of composite castings called inserts, the positioning of the inserts in a centrifugal die, the injection of SG iron in a rotating die (centrifugal die) to Composite castings are produced. The resulting castings are heat treated and tested in wear-resistant applications. It was found that the service life of the wear parts was greatly increased. Figure 5 A vertical spindle mill is described with cast metal matrix ceramic composite parts MMCC on the disc liner 8 and the grinding roll 9 .

[0058] Another disc liner wear part for a vertical mill was prepared. Mineral particle ceramic blocks are introduced in the wear surface part of the casting. Castings are cast by tr...

Abstract

The invention relates to a metal basal ceramic composite material wear part of a wear part formed by a ceramic block infused by metal. The ceramic block comprises a porcelain granule and a carbide grain with alumina. The introduction of the carbide grain reduces the abrasion. The grain with the alumina comprises an alumina, a zirconia and a titania, wherein based on the weight of the grain. The alumina content is 30-65percent of weight, the zirconia content is 30-65percent of weight and the titania content is 1-7percent of weight. The ceramic block also comprises a thin ceramic powder and the preferable ceramic powder content is 1-4percent weight of the grain.

Description

technical field [0001] The invention relates to a metal matrix ceramic composite wear part (metal matrix ceramic composite wear part) and a ceramic block used for the metal matrix ceramic composite wear part, and the invention also relates to a metal matrix ceramic composite wear part A method for preparing a ceramic cake of a component, the invention further relates to a grinding roller comprising the metal matrix ceramic composite wear-resistant component and a grinding disc of a vertical mill containing the metal matrix ceramic composite wear-resistant component Liner (table linear). [0002] Many industrial applications include components that are subject to wear during their service life. Components with wear-resistant properties are often used in the cement industry, mining industry and thermal power generation industry. Historically, 12% manganese steels and nickel-containing wear-resistant cast irons (Nihards) were used for wear-resistant applications in the first ha...
