Silicon carbide products
Silicon carbide products have good thermal stability and good thermal conductivity (6-8 times of clay and high alumina products). Under high temperature, high intensity and high corrosion resistance, chemical erosion resistance. For heat treatment furnace, laboratory muffle furnace, glass anneal furnace, ceramic sintering, thermal diffusion furnace and other equipment. Ninety-five silicon carbide products, Sic more than 95%, with good refractoriness and RUL, not easily oxidized at high temperatures. It is an ideal building material for industrial high temperature furnace.
SiC products include carburizing furnace brick, high wear-resistant steel billet rail brick, brick platform
For carburizing furnace, anti-infiltration porcelain surface SiC radiant tube
Wearable SiC continuous heat treatment furnace
