Silicon carbide refractory bricks is mainly made of silicon carbide as the main raw material of high quality refractory products with the content of silicon carbide in 72%~90%. The raw material is usually black silicon carbide (with a SiC content of 96% or more). Add the binder (or not add the binder), after the ingredients, mixing, molding and firing process.
The main crystal phase of silicon carbide refractory bricks is silicon carbide, the 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-silicon carbide brick.
This series of refractory brick has excellent wear resistance and corrosion resistance, high temperature strength, good thermal shock stability, high thermal conductivity, low coefficient of thermal expansion and other characteristics, belonging to high performance refractory materials. Because of the high thermal conductivity, silicon carbide brick has good wear resistance, thermal shock resistance, corrosion resistance, so this series of refractory brick is widely used in the industry.
Silicon carbide refractory bricks can be used for metallurgical steel cylinder lining, nozzle, plug, blast furnace bottom and furnace belly, heating furnace without water cooling slide track; Non-ferrous metal smelting distiller, rectifying tower tray, side wall of electrolytic cell, melting metal crucible; Cover plate and flame insulating material for silicate industrial kilns; Oil and gas generator and organic waste combustion furnace in chemical industry; The lining of aluminum electrolytic cell for high technology ceramic kiln, melting aluminum conduit and kiln for ceramic kiln, the lower part of furnace body, furnace waist and furnace belly of large and medium-sized blast furnace, lining of aluminum refining furnace, lining of zinc distillation tank, etc.
Silicon carbide brick products have good thermal stability and high thermal conductivity, and good corrosion resistance, is an ideal energy-saving material for industrial kilns. We are a professional production of refractory products of high quality manufacturers, welcome to consult and purchase.
