Special fire-proof material for combustion furnace and preparation method thereof
The invention provides a special fire-proof material for a combustion furnace and a preparation method thereof, and relates to the technical field of fire-proof materials and production, and the components and mass ratios of raw materials for preparing the special fire-proof material are as follows: 50 to 70 parts of silicon carbide, 10 to 25 parts of silicon nitride powder, 3 to 10 parts of silica powder, 0.1 to 1 part of aluminum powder, 5 to 15 parts of alumina micro powder, 0.3 to 1.8 parts of rare earth addition yttrium oxide, 0.3 to 1.8 parts of rare earth addition lanthanum oxide, and 1 to 2 parts of binding agents. The special fire-proof material has the advantages of good thermal shock resistance and oxidation resistance, high strength, large thermal conductivity, low dilatation coefficient, high performance, and long service life, and the combustion field temperature in a combustion process can be improved, and the combustion efficiency is increased.
