We are a refractory material manufacturer, with four major factories: heavy brick factory, light brick factory, monolithic refractory factory and fused-cast brick factory.
We promise to provide you with high-quality refractory materials.
Product introduction of silicon carbide brick
Silicon carbide bricks are made of industrial SiC as raw material, and the refractory brick mainly made of calcined SiC. It has high thermal conductivity, high thermal conductivity, small coefficient of linear expansion, good thermal shock, high temperature abrasion resistance, and excellent chemical corrosion resistance.
Features of silicon carbide brick
Silicon carbide bricks have high wear resistance, corrosion resistance, high temperature strength, good thermal shock stability, high thermal conductivity, low thermal expansion coefficient, and so on.
Application of silicon carbide brick
Silicon carbide bricks are widely used in the industrial range. It can be used for the inner wall of the metal fountain tube, water mouth, plug head, blast furnace bottom and furnace belly.
