Product Details

Product Description

Silicon carbide is a man-made mineral, it is a covalent bond compound, it is the existence of this bond, so that it has high strength, hardness. The shed board, push board, slide board, support, sagger, flame slide, etc. produced with silicon carbide as the main raw materials. With the inherent characteristics of silicon carbide, with the product load softening and wear resistance, fast heat conduction, oxidation resistance, high temperature strength, long service life and other characteristics. Our factory produces silicon carbide products of various specifications all year round, and there are various kinds of special silicon carbide bricks (arch bricks) against kiln and furnace openings. The product has good thermal performance, high thermal stability, no deformation, no softening, no expansion under high temperature for a long time, and can maintain the inherent high thermal conductivity of silicon carbide. The product is also characterized by wear resistance and erosion.

Silicon nitride bonded silicon carbide Plate

Silicon nitride bonded silicon carbide plate 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. 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
