We are offering castables. Specifications low cement refractory castable refractory castable manufacturer al2o3: 45-90% density: 2.3-3g/m3 low iron low cement refractory castable refractory castable manufacturer al2o3: 45-90% density: 2.3-3g/m3 low iron 1. The dosage of cement is low, the content of calcium only accounts for 1/4-1/3 of common refractory castable2. Wter consumption rate during the construction is almost 1/2 or 1/3 of the common refractory castable, so the low cement refractory castable has high density and low porosity. 3. High normal temperature cure property, intensity will be increased after medium temperature and high temperature. Three or five times more than common refractory castable. 4. Good volume stability under high temperature.
