More Information
Summary:The invention discloses a semi-lightweight aluminum silicon carbide carbon brick and a preparation method thereof, wherein the preparation method includes the following steps: mixing 60-80 wt% of a Guyana bauxite raw material, 5-15 wt% of a graphite raw material, 5-20 wt% of a premixed powder and 3-5 wt% of a binder uniformly, carrying out compression molding forming, and baking at low temperatureto obtain the semi-lightweight aluminum silicon carbide carbon brick. Compared with ordinary high-aluminum bauxite, Guyana bauxite has the characteristics of fewer impurities, high purity, high apparent porosity and low bulk density, and can replace ordinary high-aluminum bauxite and corundum for use at the same time; the semi-lightweight aluminum silicon carbide carbon brick prepared by the lightweight Guyana bauxite has the advantages of low bulk density, good thermal shock stability, corrosion resistance, effective reduction of thermal conductivity, energy saving and consumption reduction;and compared with ordinar
