Silicon carbide bricks are type of refractory material primarily composed of carbon and silicon dioxide (SiO₂), known for their high refractoriness, excellent thermal shock resistance, and low thermal expansion coefficient. They are widely used in industries such as steel, glass, ceramics, and cement. · High Refractoriness: With a refractoriness exceeding 1600°C, they are suitable for high-temperature environments. · Excellent Thermal Shock Resistance: Capable of withstanding rapid temperature changes, minimizing thermal shock damage. · Low Thermal Expansion Coefficient: Maintains dimensional stability at high temperatures. · Good Resistance to Acidic Slag Erosion: Strong resistance to acidic slag. · High Thermal Conductivity: Exhibits high thermal conductivity, facilitating uniform heat transfer.
Steel Industry: Used in the lining and bottom of electric furnaces and converters.
Glass Industry: Employed in the melting tanks and forehearths of glass furnaces.
Ceramics Industry: Utilized in the kiln cars and walls of ceramic kilns.
Cement Industry: Applied in the preheaters and decomposition furnaces of cement rotary kilns.
