What are refractory materials
Refractoriness not less than 1580 ℃ a class of inorganic non-metallic materials. Refractoriness is a refractory material cone specimen in the absence of load, resistance to high temperature without softening the role of melting down the temperature in Celsius. But only to refractoriness to define has been unable to fully describe the refractory materials, 1580 ℃ is not absolute. Now defined as any physical and chemical properties allow its use in high-temperature environment is called refractory materials. Refractories are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount in the metallurgical industry, accounting for 50% to 60% of the total output.
