描述
It is an amorphous refractory material which is directly used for refractory aggregates, powders and cements with water or other liquids and is not calcined. It is also called refractory potting material, castable or refractory concrete.
Advantage:
The refractory concrete is a non-burning product, which is convenient for construction, saves energy, can be shaped according to needs, and the overall structure is better than the brick lining. It is suitable for mechanized construction, and the life of the lining can be prolonged when used reasonably.
Application:
Refractory concrete is mainly used in industrial kilns such as metallurgy, petroleum, chemical industry and machinery. The service temperature is lower than 900 °C, mainly used in the base layer of thermal equipment, chimneys, flue and other structures.
