Refractory Materials

              Refractory is the inorganic nonmetal material with a refractory degree of at least 1500 ℃. The degree of fire resistance refers to the temperature at which the conical specimen of the refractory material resists high temperature without softening the melting. Refractories are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields, in the metallurgical industry with the largest amount of total production of $number. Refractories according to the degree of fire resistance can be divided into ordinary refractory, high-grade refractory and super refractory.Refractory Materials

              Alkaline refractories are magnesium oxide, calcium oxide as the main component, commonly used is Magnesia brick. Magnesia bricks containing Magnesia $number above, have good resistance to alkaline slag and slag, and have higher refractoriness than clay bricks and silica bricks. Mainly used in open hearth, blowing oxygen converter, electric furnace, non-ferrous metal smelting equipment and some high-temperature equipment.Refractory Materials

              Refractory materials used in special occasions have high temperature oxides, such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconia, refractory compounds, such as carbide, nitride, Boride, silicide and sulfide; High temperature composite materials, mainly metal ceramics, high-temperature inorganic coatings and fiber reinforced ceramics.Refractory Materials

              Often used refractories have AZS bricks, corundum bricks, direct combination of magnesia-chrome bricks, silicon carbide bricks, silicon nitride bonded silicon carbide bricks, nitride, silicide, sulfide, boride, carbide and other non-oxide refractory materials, calcium oxide, chromium oxide, alumina, magnesium oxide, beryllium oxide refractory.Refractory Materials
