Description

Technical Field

[0002] Refractory materials are a class of inorganic non-metallic materials with a refractoriness of not less than 1580℃. Refractoriness refers to the Celsius temperature at which a conical specimen of a refractory material resists high temperature without softening or melting under no load. However, defining refractory materials solely by refractoriness is no longer sufficient to fully describe them. 1580℃ is not absolute. It is now defined as any material whose physical and chemical properties allow it to be used in high-temperature environments. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. During the processing of refractory materials, it is often necessary to mix their ingredients to combine various raw materials to form refractory materials.
