Basic knowledge of refractories
What is refractory? 
Refractories generally refers to the degree of fire at 1580 degrees Celsius above the inorganic non-metallic materials, including natural minerals and in accordance with certain requirements of a variety of products through a certain process.It has a certain high temperature mechanical properties, good volume stability, is a variety of high temperature equipment necessary materials.
How is refractory material classified?
There are a lot of classification methods of refractory materials, but the main ones are divided according to the chemical composition;According to the degree of fire resistance: can be divided into ordinary refractories (1580 - 1770~℃, advanced refractories (1770—2000℃), 3000~℃ (2000~℃) and super refractory material (greater than);
Manufacturing process; divided by processing can be divided into: sintering products, casting products, not burning products; divided by purpose: can be divided into blast furnace, converter, open hearth furnace, continuous casting, glass kiln, refractory materials for cement kiln;According to the appearance of division can be divided into: Refractories, refractory clay, unshaped refractory materials; according to the shape and size can be divided into: standard type, general type, special, special and super special products;According to the forming process of division can be divided into natural rock cutting, mud casting, plastic molding, molding and semi dry vibration, ramming, casting and other products;The chemical composition divided by a mineral can be divided into: (aluminium silicate clay brick, high alumina brick, semisilica brick), silica (silica brick, magnesia, fused quartz burning products) (brick, magnesia brick, magnesia chrome brick); carbon (carbon brick, Shi Mozhuan), dolomite, zircon, special refractory materials products (high purity oxide products, refractory compound products and high-temperature composite materials).
