High Alumina Refractory Cement Product Description
Refractory cement is made of high-quality bauxite and high-quality lime as raw materials, which are mixed into raw materials with appropriate components in a certain proportion. Hydraulic cementitious material. The refractoriness of refractory cement is not less 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.
Refractory cement can be used to cement various refractory aggregates (such as corundum, calcined bauxite, etc.) to make refractory mortar or concrete, and be used for cement rotary kilns and other industrial kilns as linings.and can be made to low cement high alumina castable to build or repair all kinds of furnace and kilns for thermal insulation or acid erosion resistance with high strength.
