SIC Beam
Silicon carbide beams have high temperature bearing capacity, long-term use without bending and deformation, and their service life is several times that of other materials. It is an ideal kiln furniture for industries such as sanitary porcelain and electric porcelain.
Description
Product details:
Silicon carbide products are high-grade refractory materials produced by sic as the main raw material, with various binders and fired at high temperature. It has good thermal conductivity, high temperature strength, wear resistance, corrosion resistance, and thermal stability. and other outstanding performance.
Product Feature :
Silicon carbide square beam has the characteristics of high temperature resistance, high flexural strength, thermal shock resistance, no bending, good thermal stability, high temperature bearing capacity, no slag falling, and strong oxidation resistance.
Product Application:
Silicon carbide beams are widely used in metallurgical industry, blast furnace belly, open tap hole, electric porcelain, sugar porcelain, muffle plate, shed plate, muffle plate, push plate, saggar, pillar, glass annealing furnace, etc. Production of various special-shaped and special-shaped products.
