Refractory cement is also called high temperature cement.
Any raw material that uses high-quality bauxite and high-quality lime as raw materials is mixed in a certain proportion to form an appropriate amount of raw material. After sintering, the clinker with aluminate as the main component is obtained, and then ground into fine powder to make refractory clinker. The hydraulic cementitious material is called refractory cement.
The refractoriness of refractory cement is not lower than 1580 degrees Celsius. According to different compositions, it can be divided into aluminate refractory cement, low calcium aluminate refractory cement, calcium magnesium aluminate cement and dolomite refractory cement.
