Graphite-aluminosilicate composite refractory material as well as preparation method and application thereof
The invention discloses a graphite-aluminosilicate composite refractory material as well as a preparation method and an application thereof. The graphite-aluminosilicate composite refractory materialcomprises a refractory brick matrix and a high-temperature-resistant coating sprayed on the surface of the refractory brick matrix, wherein the refractory brick matrix is an aluminosilicate shaped refractory brick, and the high-temperature-resistant coating is prepared from the following raw materials in percentage by mass: 25-35 percent of crystalline flake graphite, 55-65 percent of amorphous graphite, 2-8 percent of a suspending agent and 2-5 percent of other auxiliaries. The refractory brick matrix is sprayed by the raw materials of the high-temperature-resistant coating in a spraying manner to obtain the graphite-aluminosilicate composite refractory material. The material has the advantages of low cost, high high-temperature strength, high erosion resistance, no pollution to steel/molten iron, simple process and huge economic benefit, and is suitable for industrial large-scale production.
