Abstract
The invention discloses a silicon-carbide composite corundum mullite brick, which is manufactured through the following raw materials in parts by weight: 60-90 parts of natural calcined mullite with the particle size of 4-0mm, 5-20 parts of corundum powder with the particle size of 120-320 meshes, 5-25 parts of silicon carbide with the particle size of 120-320 meshes, 5-10 parts of clay powder with the particle size of 120-200 meshes and 3-5 parts of water. According to the invention, with the natural calcined mullite as the main raw material and the added silicon carbide and the corundum powder, the silicon-carbide composite corundum mullite brick is formed through high pressure and sintered at a high temperature, is used in a bosh and a furnace crucible of a small and medium-sized blast furnace, can resist the high temperature of 1700-1800 DEG C, and has the advantages of same performance compared with that of the traditional corundum mullite brick, low price, high cost-performance ratio and good economic benefit.
