注：1、可根据需方要求，生产各种规格的异型砖。
2、可根据需方要求，生产其他材低火材料。如耐砖、空心隔热砖等。
3、能承接各种窑炉的设计、指导、按装。 The main component of Bauxite is alumina, is impurities of hydrated alumina, a kind of earthy minerals. The color is white or off-white, usually it is yellow or light red due to iron. Its density is 3.9 ~ 4g/cm3, hardness 1 ~ 3, opaque, brittle and extremely difficult to melt. It does not dissolve in water, but can dissolve in sulfuric acid, sodium hydroxide solution, mainly used in aluminum smelting and refractory materials making. Uses: (1) The aluminum industry. Used in defense, aerospace, automotive, electrical, chemical and daily supplies. (2) Bauxite clinker can be processed into fine powder and made into mold. Used in military, aerospace, communications, instrumentation, machinery and medical equipment sectors. (3) Used for fire-resistant products. The refractoriness of High-alumina clinker is up to 1780℃, it has strong chemical stability and good physical properties. (4) Aluminosilicate refractory fibers. With a light weight, high temperature, thermal stability, low thermal conductivity, heat capacity of small and resistance to mechanical vibration and so on. Used for iron and steel, nonferrous metallurgy, electronics petroleum, chemical space, atomic energy, defense and other industries. (5) Using magnesia clinker and bauxite as raw material, by adding the appropriate amount binder, you can get a better effect of barrel lining. (6) Used to produce alumina cement, abrasive materials, ceramic industry, as well as a variety of aluminum compounds.
