Refractory Material

- Aug 09, 2018 -

Refractory material is a class of inorganic nonmetallic materials with a refractory degree of not less than 1580 degrees. Refractivity refers to the temperature at which a conical specimen of refractory resists high temperature without softening the melting down without loading. However, the definition of refractoriness alone cannot fully describe the refractories. 1580 degrees is not absolute. It is now known that any material that is allowed to be used in high temperature environment is called refractory material. Refractory materials are widely used in metallurgical, chemical, petroleum, mechanical manufacturing, silicate, power and other industrial fields, the largest amount in the metallurgical industry, accounting for the total output of 50%~60%.
