Refractory material

A class of inorganic non-metallic materials with a fire resistance of not less than 1580 ° C. Refractory refers to the Celsius temperature of the refractory cone sample that resists high temperature without softening and melting without load.

But the definition of refractory alone can no longer fully describe refractories, 1580 ℃ is not absolute. It is defined as any material whose physical and chemical properties allow it to be used in high temperature environments is called refractory material.

Application of refractory material

Refractories are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. The largest amount of refractory in the metallurgical industry, accounting for 50% to 60% of the total output.
