Henan refractory products factory Abrasion Resistance SiC Silicon carbide brick for copper refining furnace

Silicon carbide brick is a refractory material made of SiC as the main raw material. Mohs hardness 9. It is more stable for acid slag. Containing SiC 72% ~ 99%. The bricks are divided into clay binding, Si3N4 binding, Sialon binding, -SIC binding, Si2ON2 binding and recrystallization. It is mainly used in retort, cast aluminum mold, electric furnace lining and heat exchanger, etc.

Silicon nitride bonded silicon carbide brick
Silicon nitride bonded silicon carbide brick is a refractory product made by nitriding and firing using SiC and Si powder as raw materials. Its characteristic is Si3N4 as the binding phase. Si3N4 exists between SiC crystal grains as needle-like or fibrous crystals and is an important new refractory material.

Product procession:
Using the principle of reaction sintering, the SiC green body containing silicon powder is sintered by the nitridation reaction, and the firing process is completed in a closed furnace with nitrogen gas and easy control. The temperature, pressure and atmosphere in the furnace must be strictly controlled. Main process parameters: nitriding gas pressure 0.02~0.04MPa, furnace atmosphere containing O2 less than 0.01%, final nitriding temperature 1350~1450℃, total nitriding time varies with product shape and size.

Features and Appliciation:

Silicon nitride bonded silicon carbide bricks have good alkali corrosion resistance, molten cryolite wettability, oxidation resistance, wear resistance, high thermal conductivity, thermal shock resistance and extremely low electrical conductivity.
Silicon nitride combined with silicon carbide bricks are mainly used as the lining of the lower furnace body of the blast furnace, which is more than twice as long as the use of traditional refractory materials. In addition, it can be used as the lining of aluminum reduction electrolyzers and ceramic kiln furniture, which can save energy, increase life It can also be used as a blast furnace tuyere water-cooled pipe sleeve brick because of its advantages such as environmental pollution
