Refractories (Refractory material) according to the chemical composition of the mineral can be divided into eight categories: (1) siliceous material; (2) silicate materials; (3) magnesia materials; (4) dolomitic material; (5) chrome material; (6) carbonaceous material; (7) zirconium materials; (8) special refractories (Refractory material). According to the chemical composition of the mineral classification can better reflect the refractories (Refractory material) of the material, structure and characteristics of the refractory nature of the lowest price, so this is currently the most widely used classification applications. Ordinary refractory frequently used (Refractory material) have brick, half brick, clay brick, high alumina brick, brick and so on. Special materials are often used are AZS brick, corundum brick, magnesite-chrome brick directly bonded silicon carbide bricks, silicon nitride, silicon carbide bricks, nitrides, silicides, sulfides, borides, carbides and other non-oxide refractories (Refractory material); calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide refractories (Refractory material). Insulation refractories (Refractory material) diatomite products, magnesia products, insulation boards are often used. Unshaped refractories frequently used (Refractory material) have fettling, refractory ramming, refractory castable, refractory plastic, refractory clay, refractory gunning refractory cast materials, fire-resistant steel, lightweight refractory castable, gun mud and other refractories agent shangzhuang Refractories (certified), Shijiazhuang, Zhengzhou City refractories by shangzhuang Refractories Limited.
