About Low Cement Alumina Castable 85% Al2O3, with Chromium Oxide P-CAST-A85Cr
Low Cement Alumina Castable 85% Al2O3, with Chromium Oxide P-CAST-A85Cr is a low cement castable based on bauxite and special additives with 82 – 85% Al2O3, suitable for service temperatures up to 1700 °C. It has a hydraulic bond and is installed by casting with vibration. Material type according to the datasheet: Low cement, dense refractory concrete; raw material basis: bauxite and special additives.
Low cement castables contain less cement and therefore need less mixing water, which gives a higher density, lower porosity and higher strength than conventional castables of the same family. Chromium oxide improves resistance to slag penetration.
Technical properties
- Maximum service temperature: 1700 °C
- Al2O3: 82 – 85%
- Bulk density: 2.5 – 2.9 g/cm³
- Grain size: 0 – 8 mm
- Cold crushing strength after drying at 110 °C: 450 – 550 kg/cm²
Installation, packaging and storage
Installation: casting with vibration. Water addition, drying and initial heat-up should follow the manufacturer's instructions to achieve the best properties. Packaging: 25 kg bags (dry mix, water is added on site). Shelf life: 6 months (dry, cool, frost-free place).
