Silica carbide brick is a kind of refractory product mainly made of SiC, the silica carbide content is 72%~99%. Generally, the black silica carbide( content above 96%), add binding agent(or non-binding agent), made by the burdening, mixing, molding and burnt. The principal crystalline phase is SiC.
Clay bonded silicon carbide brick.
Clay-bonded silicon carbide brick is a refractory product made of silicon carbide as the main raw material and clay as a binder. It is characterized by high thermal conductivity, low thermal expansion coefficient, good thermal shock resistance and wear resistance. It is the earliest developed type of silicon carbide bricks.
Clay bonded silicon carbide bricks use black silicon carbide as the raw material. Its chemical composition: SiC 98.0%, free C 0.5%, Fe 0.2%, and free SiO2 0.6%. Soft clay and pulp waste liquid with good bonding properties are used as binders. In the past, the proportion of bonded clay used was relatively large, generally 10% to 15%, and now 3% clay and 5% pulp waste liquid are used. The thermal conductivity of silicon carbide bricks with a small amount of clay added is 3 to 4 times higher than that of silicon carbide bricks combined with more clay, and the load softening temperature and slag resistance are also higher. The manufacturing process of clay-bonded silicon carbide bricks with 3% bonded clay is to prepare coarse, medium and fine SiC according to the particle gradation that can obtain the maximum bulk density. Dry mixed uniformly first, then add clay, dry mixed for 3 minutes, add 4% pulp waste liquid (density 1.26~1.289/cm3), and mix. The water content of the mud is about 1.5%. After 12 hours of trapping, the mud is passed through a 4mm screen and formed by a brick press. The brick volume density is 2.5~2.79/cm3. Dry for 2 to 4 days under natural drying conditions and fire in a tunnel kiln at a firing temperature of 1400°C.
The product is used as ceramic kiln furniture (shelf, support, sagger, etc.), muffle cover for muffle furnace, lining brick for aluminum refining furnace, distillation tank for zinc distillation furnace, cement rotary kiln cooler, etc.
