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.
