Silicon carbide Fire Proof brick thermal resistant standard refractory brick for Industrial furnaces
Silicon carbide Fire Proof brick is one high grade refractory that takes SiC as raw material, with features of good wear resistance and erosion resistance, strong high temp strength, high thermal conductivity, low linear expansion and good thermal shock resistance.
Silicon carbide Fire Proof brick is widely used in different areas, in steel metallurgical industry, mainly used in steel ladle lining, the bottom of blast furnace, electric furnace etc. Also used in non-ferrous metal industry, oil-chemical industrial kilns.
The properties of SiC brick largly depends on the state of the crystalline phase, commonly used is clay combined SiC products, usually more clay added, the lower refractoriness is.
