      High Alumina Brick

      High alumina bricks are of different shapes, which is widely applied for industrial kilns and furnaces in the field of metallurgy, machinery, chemical industry, electric power, building material, light industry, etc.

      Description of High Alumina Brick:

       

      High alumina bricks are of different shapes, which is widely applied for industrial kilns and furnaces in the field of metallurgy, machinery, chemical industry, electric power, building material, light industry, etc.

       

      High alumina bricks are mainly used for masonry blast furnace, hot stove, electric furnace top, blast furnace, reverberatory furnace, rotary kiln lining. In addition, high alumina bricks are also widely used to do flat furnace regenerative lattice brick, pouring system with the plug head, water tank and so on.

       

      There are many kinds of high alumina bricks like blast alumina brick, casting port brick, etc. The main advantage: high intensity, strong resistance to corrosion, good thermal shock stability and performance.
       
      There are also different refractoriness and melting point of high alumina brick. In fact, the melting point is the critical point temperature of liquid crystal turnning to solid state. Most of bricks is conposed of a lot of material, and its melting point is not constant, Liguid began to melt completely requires a gradual process. Over a wide range of temperature environment, Solid-liquid is present together, it can be explained bricks at a high temperature to soften and melt features, so, we use refractoriness to measure, which is the temperature reacheing a certain degree of softening.

      Features of High Alumina Brick:

       

      a, refractoriness

      Alumina brick refractoriness are higher than clay and semi-silica brick, which can be 1750 ~ 1790 ℃, belonging to high-grade refractory.

       

      b, load softening temperature

      Because high aluminum bricks has high Al2O3 content, less impurities, less fusible vitreous, so load softening temperature is higher than that of clay brick. While mullite has not formed crystalline mesh tissue, the load softening temperature is still not higher than that of silica brick.

       

      c, slag resistance

      there are more Al2O3 in high alumina bricks, which is close to neutral refractory, resistant to erosion of acid and alkaline slag, because it contains SiO2, so the resistance ability to alkaline slag is weaker than resistance acid.
