Abstract

The invention belongs to the technical field of refractory materials, and specifically relates to a high-thermal-conductivity wear-resistant refractory material and a preparation method thereof. The high-thermal-conductivity wear-resistant refractory material has a formula which comprises the following raw materials by weight: 4-5 parts of a clay raw material, 1-2 parts of a quartz raw material, 1-2 parts of a feldspar raw material, 5-6 parts of a magnesium raw material, 2-3 parts of an aluminum raw material, 1-2 parts of graphite and 0.5-1.5 parts of an additive. The high-thermal-conductivitywear-resistant refractory material provided by the invention is manufactured by adopting a manner of multi-layer stacking of ceramic layers and magnesia carbon brick layers, and has the advantages ofhigh thermal conductivity, wear resistance and fire resistance.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a high thermal conductivity wear-resistant refractory material and a preparation method thereof. Background technique [0002] A class of inorganic non-metallic materials with a refractoriness not lower than 1580°C. Refractoriness refers to the Celsius temperature at which a refractory conical sample can resist high temperature without softening and melting without load. However, it is not possible to fully describe refractory materials only by the definition of refractoriness, and 1580°C is not absolute. It is now defined as a material whose physical and chemical properties allow it to be used in a high temperature environment is called a refractory material. Refractory materials are used in various fields of the national economy such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, and mili...
