Refractoriness refers to refractory cone sample in which there are no load cases, resistance to hightemperature function and not soften the Celsius temperature not less than 158℃ refractoriness of inorganic non-metallic materials. But just to define the refractoriness cannot fully describethe refractory materials, 1580 ℃ is not absolute. Now defined as any physical and chemical properties to allowits use in high temperature environment is called refractory material. Refractory material is widely used inmetallurgy, chemical industry, petroleum, machinery manufacturing, silicate, motivation and other industrialarea, etc. The dosage in metallurgy industry is the biggest, accounts for 50% ~ 60% of total output.Although the definition of national regulation is different, for example, the international organization forstandardization (ISO) in the official publication of international standard, "refractory material, the refractoriness isat least 1500 ℃ of nonmetallic materials or products (but do not rule out that contain a certain proportion ofmetal)", but the basic concept is the same, namely the refractory material is the structure material used for hightemperature furnace, furnace thermal equipment, as well as high temperature containers and components ofmaterials used in industry, and can withstand the corresponding physical and chemical change andmechanical action.
According to the refractoriness, can be divided into ordinary refractory products (1580 ~ 1770 ℃), high-gradrefractory products (1770 ~ 1770 ℃) and super refractory products (above 2000 ℃).In metallurgy, silicate, chemical, power, petroleum, machinery manufacturing industry, refractory material is used widely.
