Classification of refractory materials
Classification: A、 Classification by chemical composition (1) Silica products; (2) aluminum silicate refractory products ; (3) Magnesium refractory products; (4) dolomite refractory products; (5) chrome refractory products; (6) carbonaceous refractory products; (7) zirconium products; (8) special products. B、 By chemical characteristics (1) acidic refractory. Acid refractory material is based on silica as the main component of the refractory material, mainly refers to the silica brick and zircon brick. Acidic refractory materials can be resistant to acid slag erosion. (2) neutral refractory. Neutral refractory mainly refers to refractory materials such as corundum refractory brick, high alumina brick, silicon carbide brick, silicon nitride brick and carbon refractory brick, mainly made of aluminum oxide, chromium oxide, silicon carbide and carbon as the main components. Its characteristics are acidic slag and alkaline slag have a corrosion resistance. (3) alkaline refracto...
