Description

Technical Field

[0002] A type of inorganic non-metallic material with a refractoriness of not less than 1580℃. Refractoriness refers to the Celsius temperature at which a cone-shaped specimen of a refractory material can resist high temperature without softening and melting under no load. However, defining it only by refractoriness can no longer fully describe refractory materials, and 1580℃ is not absolute. It is now defined as any material whose physical and chemical properties allow it to be used in a high temperature environment is called a refractory material. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. They are used the most in the metallurgical industry, accounting for 50% to 60% of the total output.
