Description

technical field

[0001] The invention relates to an environment-friendly refractory material and a preparation method thereof, belonging to the technical field of refractory material preparation. Background technique

[0002] Refractory materials are used in various fields of the national economy such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, and military industry. They are essential materials to ensure the production and operation of the above industries and technological development. It plays an irreplaceable important role in the development of high temperature industrial production. A class of inorganic non-metallic materials with a refractoriness not lower than 1580°C. Refractoriness refers to the Celsius temperature at which a refractory conical sample can resist high temperature without softening and melting without load. However, it is not possible to fully describe refractory materials...
