The Function of Refractory Materials

Date:2017-06-15 14:34 From:Zhengzhou Sunrise Refractory Author:sunrise
Refractoriness refers to refractory cone sample in which there are no load cases, resistance to high temperature function and not soften the Celsius temperature. Refractory materials is not less

than 1580 ℃ refractoriness of inorganic non-metallic materials. But just to define the refractoriness cannot fully describe the refractory materials, 1580 ℃ is not absolute. Now defined as any

physical and chemical properties to allow its use in high temperature environment is called refractory material. Refractory material is widely used in metallurgy, chemical industry, petroleum,

machinery manufacturing, silicate, motivation and other industrial area, 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 for standardization (ISO) in the official publication of international standard, "refractory material,

the refractoriness is at least 1500 ℃ of nonmetallic materials or products (but do not rule out that contain a certain proportion of metal)", but the basic concept is the same, namely the refractory

material is the structure material used for high temperature furnace, furnace thermal equipment, as well as high temperature containers and components of materials used in industry, and can

withstand the corresponding physical and chemical change and mechanical action.

According to the refractoriness, can be divided into ordinary refractory products (1580 ~ 1770 ℃), high-grade refractory products (1770 ~ 1770 ℃) and super refractory products (above 2000 ℃).

In metallurgy, silicate, chemical, power, petroleum, machinery manufacturing industry, refractory material is used widely. Metallurgical industry of refractory consumption accounted for about 50 ~

60% of the total refractory.
