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.
High Alumina Refractory Cement Features
High refractoriness, High refractoriness under load
High density, low porosity
Good slag resistance and corrosion resistance
High strength and wear resistance
Good resistance to flake performance
Good thermal shock stability
Scouring resistance
Good hot strength.
Application of High Alumina Refractory Cement
High alumina cement is mainly used to configure refractory castable such as high alumina low cement castable which can build or repair furnace or kiln for heat insulation or high temperature erosion.
