Refractory variety of different purposes, it is necessary to carry out scientific classification refractory to facilitate scientific, rational selection and management. Classification of refractories, many of them major classification chemical properties, chemical composition of mineral classification, taxonomy production process a variety of methods, materials, shape classification method. 1, according to the level of refractoriness points: General Refractories: 1580 ℃ ~ 1770 ℃ advanced refractory: 1770 ℃ ~ 2000 ℃ super refractories:> 2000 ℃ 2, according to the shape and size of the different product sub: Standard: 230mm × 113mm × 65mm; more than four ruler, (ratio) Max: Min <4: 1; Shaped: more than two-entrant, (ratio) Max: Min <6: 1; or a 50 ~ acute angle 70 °; the specific type :( ratio) Max: Min <8: 1; or no more than four concave corners; or have an acute angle of 30 ~ 50 °; special products: Crucible, containers, tubes. 3, according to the manufacturing method of refractories can be divided into: baked goods, not baked products, unshaped refractory materials chemical properties 4.
