Description
Refractory cement is made from high-quality bauxite and lime as raw materials, blended in a certain proportion to form a mixture. After sintering, the resulting clinker, which is primarily composed of aluminates, is ground into fine powder to produce a refractory hydraulic cement with excellent fire resistance. The refractoriness of refractory cement is no less than 1580°C. Depending on the composition, it can be classified into alumina refractory cement, low-calcium aluminate refractory cement, calcium-magnesium aluminate cement and dolomite refractory cement,etc.
Castable refractory mortar: high temp stability, good bonding properties, chemical corrosion resistance, wear resistance, more>
Alumina low cement castable: high refractoriness, high R.U.L, high strength, thermal shock resistance & corrosion resistance, more>
Alumina Magnesia Ramming Mass: high refractoriness, thermal shock resistance and erosion resistance, more>
