    Sillimanite Refractory Bricks Components

    Sillimanite brick belongs to neutral refractory. It is made of sillimante minerals, which can transform into mullite and free silica after high temperature firing. It is produced by the methods of high temperature firing and casting.

    Sillimanite Refractory Bricks Properties

    Sillimanite properties are better than that of high alumina bricks. Sillimanite brick is featured with high refractoriness, about 1770-1830℃, high refractoriness under load, with the RUL starting point about 1500~1650℃, low porosity, good thermal shock resistance, low creep rate at high temperature, and good wear resistance.
    The properties and advantages of sillimanite bricks can be reflected in the usages.
    Because of the high temperature resistance, high strength,  and impact resistance, sillimanite brick can used as the high temperature indirect heating material, such as the aluminium reduction cell, and copper melting furnace lining, etc.

        In the iron and steel industry, because of the corrosion resistance, thermal shock resistance, and good thermal conductivity, sillimanite brick can be used in ling of the large-scale blast furnace, thus improve the service life. In the metallurgy industry, it can be used in the wear-proof tubes, and cyclones for the strong abrasion resistance. In addition, sillimanite brick is energy saving. Because of the good thermal conductivity and good thermal shock resistance, it decreases energy consumption by 20%, and saves energy by 35%, thus improves the productivity by 20%-30%.

        In addition, sillimanite brick is also applied in the high speed scour of the hot air and molten iron slag, tuyere of the blast furnace is influenced by the thermal stress caused by the temperature difference. In order to ensure the stability of the structure, and to avoid alkaline erosion, or to prevent tuyere air from leakage, sillimanite brick is used in such parts, because of its good thermal shock resistance and spalling resistance.
