  • Fused Cast AZS Block

    Fused Cast AZS Block

    Fused cast AZS block manufacturing process mixes selected zircon sand and industrial alumina powder at a ratio of 1:1, plus a small amount of Na2O (added in the form of sodium carbonate), B2O3 (added in the form of boric acid or borax) flux, and mix well After being melted at 1800~1900, it can be cast to form a fused-cast brick containing 33% ZrO2. On this basis, using partially desiliconized zircon sand as raw material, fused-cast bricks containing 36% to 41% ZrO2 can be produced. Zirconium corundum bricks use industrial alumina powder and selected zircon sand as raw materials to produce refractory products with a ZrO2 content of 33% to 45%.
    Fused cast AZS block is an important refractory material to ensure the normal operation of glass melting furnaces. At present, glass melting furnaces increase the melting rate, extend the life of the furnace, and reduce fuel consumption mainly due to the use of this refractory material.

  • Al2O3-SiC-C Brick

    Al2O3-SiC-C Brick

  • Calcium carbide

    Calcium carbide

    Calcium carbide is an inorganic compound, white crystals, industrial products are gray-black lumps, and the cross section is purple or gray. It reacts violently when encountering water, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding, etc. Physical and chemical properties: The ore is a yellowish-brown or black blocky solid, and the pure product is a white crystal (the one with higher CaC2 is purple). It has a density of 2.22 g/cm3 and a melting point of 2300°C (related to the content of CaC2). It immediately reacts violently when it meets water to generate acetylene and release heat. The melting point changes with different calcium carbide content.

  • Bauxite


    The main component of bauxite is alumina, which is hydrated alumina containing impurities and is a kind of earthy mineral. White or off-white, brownish yellow or light red due to iron content. Density 3.45g/cm3, hardness 1~3, opaque and brittle. Extremely difficult to melt. Insoluble in water, soluble in sulfuric acid and sodium hydroxide solution. Mainly used for smelting aluminum and making refractory materials.
    The composition of bauxite is extremely complex, and it is a general term for a variety of hydrous alumina ore with extremely different geological sources. Such as boehmite, diaspore and gibbsite (Al2O3·3H2O); some are composed of diaspore and kaolinite (2SiO2·Al2O3·2H2O); some are mainly composed of kaolinite and follow The increase in the content of kaolinite constitutes general bauxite or kaolinite clay. Bauxite is generally formed by chemical weathering or exogenous effects. There are few pure minerals, and always contain some impurity minerals, more or less clay minerals, iron minerals, titanium minerals and detrital heavy minerals.

  • Andalusite


    Andalusite is an aluminosilicate mineral, which is the raw material for making refractory materials and porcelain in spark plugs. It is a typical mineral of low-grade thermal metamorphism, and is commonly found in mudstones in contact with metamorphic zones.
