Silicon carbide brick is based on silicon carbide as the main raw materials. The high -purity silicon carbide powder and high -active silicon carbide are divided into mixing.
Silicon carbide tiles in silicon bricks are 72%~ 99%. Generally, black silicon carbide with SIC content of more than 96%is used as raw materials, adding binding agents (or no integrated agents), and is made through ingredients, mixing, molding and firing. The main crystal phase is silicon carbide. The main varieties are carbon bricks, carbon -carbonized carbide bricks, nitride binding carbide bricks, self -binding carbonized silicon bricks, then crystallized carbonized silicon bricks and semi -carbonized silicon bricks. It has the characteristics of abrasion resistance, good corrosion resistance, high temperature strength, good thermal shock stability, high thermal conductivity, small thermal bulk coefficient, etc., which are high -performance refractory materials.
Carbonic tiles have high thermal guidance rates, with good abrasion resistance, heat shock resistance, and corrosion resistance. Therefore, carbonized silicon bricks are widely used in industrial. Can be used for metallurgical steel tube lining, water inlet, plug head, blast furnace bottom and belly, heating furnace without water and cold sliding rails; non -ferrous metal smelting distillers, refractive tower tray, electrolytic groove side wall, melting metal cricket; silicic acid; Salt industrial kilns and flames and flames; chemical industry oil generators, organic waste burning furnaces; high -tech ceramics aluminum electrolytic tank lining, molten aluminum ducts and ceramic kiln furnaces, large and medium -sized blast furnaces, large and medium -sized blast furnaces The lower part of the body, the waist and the furnace belly, the aluminum refining furnace lining, zinc distilled can, etc.
