Silicon carbide brick sales is a refractory made of SiC as the main raw material. Mohs hardness 9. It is stable for acid slag. Contains SiC 72% ~ 99%.
It is divided into clay bonding, Si3N4 bonding, Sialon bonding, civil-sic bonding, Si2ON2 bonding and recrystallization. Silicon carbide brick sales is mainly used for making nonferrous metallurgical retort, cast aluminum mold, electric furnace lining and heat exchanger, etc.
This series of refractory bricks is main varieties are oxide-bonded silicon carbide brick, carbon-bonded silicon carbide brick, nitride-bonded silicon carbide brick, self-bonded silicon carbide brick, recrystallized silicon carbide brick and semi-carbonized silicon brick, etc. It is a high performance refractory material with good wear resistance and corrosion resistance, high strength at high temperature, good thermal shock stability, high thermal conductivity and small thermal expansion coefficient.
Silicon carbide brick sales, its coarse, medium, fine SiC formula should be 5:1:4. Black SiC is generally used to make silicon carbide brick. Its chemical composition is as follows: SiC 98.0%, free C 0.5%, Fe 0.2%, free SiO2 0.6%. Due to the different ways of combination, the process is different.
Silicon carbide refractory brick has high thermal conductivity, good wear resistance, thermal shock resistance, corrosion resistance. Therefore silicon carbide brick is widely used in industry. It can be used for lining of steel cylinder, nozzle, plug, bottom and belly of blast furnace, no water cooling slide track of heating furnace. Nonferrous metal smelting still, rectifying tower tray, electrolytic cell side wall, melting metal crucible; Oil and gas generator and combustion furnace of organic waste in chemical industry; Large and medium-sized blast furnace furnace body, furnace waist and belly, aluminum refining furnace lining.
