Product Description

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 refers to cement with a refractoriness of not less than 1580°C. Refractory cement uses bauxite and limestone as raw materials, and is a hydraulic cementitious material obtained by calcining clinker with calcium aluminate as the main component and alumina content of about 50%. 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.

High Alumina Refractory Cement Introduce

High Alumina Cement (previously called bauxite cement) is a kind of grinding hydraulic cementing materials with clinker about 50% alumina content and has calcium aluminate as the main material, which is also called refractory cement, which 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.
 

High Alumina Refractory Cement Features 

High refractoriness, High refractoriness under load
High density, low porosity
