Andalusite aluminum silicon carbon brick is also called andalusite silicon carbide brick or andalusite silicon carbide carbon brick. It is mainly used in torpedo ladle, molten iron tank and ladle. Its service life is superior to that of traditional aluminum silicon carbide carbon brick. The main reason is that the original bauxite raw material and corundum raw material are replaced by andalusite raw material. The micro expansion of andalusite raw material at high temperature makes the masonry structure of the product more compact and is not easy to be penetrated by molten iron. The anti peeling performance of andalusite raw material is better than that of bauxite and corundum, which reduces the fracture phenomenon of the product during use. Meanwhile, the andalusite raw material forms mullite phase by itself or with other raw materials during high temperature use, Corundum phase and other high-temperature mineral phases improve the performance of the product under high temperature. Therefore, andalusite aluminum silicon carbon brick can better adapt to the working conditions of molten iron tank, ladle and torpedo ladle, and achieve better use effect.
