      Corundum Brick

      Corundum bricks are widely employed in the field of petrochemical industry and refractory to build the lining of high temperature furnace and firing chamber. Alumina content is greater than 90%.

      Description of Corundum Brick:

       

      Corundum brick is made from high quality fused corundum. With scientific grading and high quality addictive, corundum bricks are shaped under high pressure and fired with high temperature. Corundum Brick has the features of high strength, excellent thermal and erosion resistance, stable chemical performance.

       

      Jinshi corundum bricks are widely employed in the field of petrochemical industry and refractory to build the lining of high temperature furnace and firing chamber.

       

      Features of Corundum Brick:

       

      • Alumina content is greater than 90%.

      • High compressive strength at room temperature (up to 340MPa).

      •  High load softening starting temperature (greater than 1700 ℃).

      •  Good chemical stability, strong resistance to acidic or basic slag, metal and glass fluid, etc.

      •  Corundum Brick can be two kinds - corundum bricks and fused corundum brick. Respectively Sintered alumina and fused corundum as raw material.

       

      Corundum Brick Classification:

       

      Corundum: brown corundum brick takes bauxite, coke (anthracite) as the main raw material, fired in the electric arc furnace in the 2000 degree high temperature.

         

      White corundum: white corundum brick is based on alumina powder as raw material, made by high temperature melting.

        

      High alumina corundum: high alumina corundum brick uses high-quality bauxite as the main raw material, processed in high temperature furnace for smelting in the 2500 .

        

      Zirconia corundum: high alumina corundum brick adopts high-quality bauxite as the main raw material, smelting in high temperature furnace in the 2500 .

        

      Monocrystalline corundum: single crystal fused alumina (also known as 32A)

       

      Abrasive: single crystal corundum takes bauxite as the main raw material, with the right amount of sulfide, made by high temperature melting.

        

      Microcrystalline corundum: microcrystalline corundum adopts bauxite as the main raw material, processed in high temperature smelting and quenching.
