Silicon Carbide Furniture And Lining For Furnaces, high reliability and economy in operation
Our company is engaged in R&D, production and sale of high-performance silicon carbide products, including reaction-bonded silicon carbide radiant tube inner tube, desulfurizing nozzle, beam, roller rod, thermocouple protection tube, cold-air tube, case, crucible, blast nozzle, axle sleeve, sealing element, and various high-temperature resistant, wear-resistant, corrosion-resistant silicon carbide irregular parts.
The reaction-bonded silicon carbide ceramic products, with high strength, high rigidity, wear resistance, high-temperature resistance, corrosion resistance, antioxidation, thermal-shock resistance and good thermal conductivity, quick-cooling/quick-heating resistance, and high-temperature creep resistance, are widely applied to military industry, aerospace and aviation, nuclear power, liquid crystal, metallurgy, chemicals, machinery, automobile, paper-making, medicine, etc.. Our products are sold to more than 40 countries and regions, such as USA, Germany, Japan, Korea, UAE, South Africa, Taiwan, etc.
Technical ceramics due to its exceptional properties is widely used for the production of refractory products, including lining and fittings of various shapes for furnace equipment:
- corrosion resistance;
- resistance to heat shock;
- stability of shape and strength preservation at the maximum operating temperature;
- low weight;
- high reliability and economy in operation.
