What Are Refractory Materials?
Refractory Materials generally refer to the inorganic nonmetallic materials with refractoriness over 1580 degree. Refractory Materials include natural ore and all kinds of products that are manufactured according to certain aim requirements and certain process, which have certain high temperature mechanical properties and good bulk density stability. Refractory Materials are the necessary materials of all kinds of high temperature equipments.
Refractoriness is centigrade degree at which refractory cone-shaped sample will be not soften and melting against high temperature function under the situation that without loading. But the 1580℃ is not absolute caused that refractory materials cannot be fully described just based on the definition of refractoriness. Now it is defined as the materials whose physicochemical property allowing it can be used in the high temperature condition. Refractory is widely used in the industry fields of metallurgy, chemical engineering, petroleum, machine manufacturing, silicate and power, of which metallurgical industry taking the biggest coverage that amounting 50-60 % of total amount.
