About Alumina Castable 96% Al2O3 P-CAST-A96
Alumina Castable 96% Al2O3 P-CAST-A96 is a conventional castable based on tabular alumina and special additives with Approx. 96% Al2O3, suitable for service temperatures up to 1820 °C. It has a hydraulic bond and is installed by casting with vibration. Material type according to the datasheet: Dense refractory concrete; raw material basis: tabular alumina and special additives.
Conventional castables contain more calcium aluminate cement. They are easy to install, but need more water and have a higher porosity after firing than low cement grades, so they are not intended for direct contact with molten metal.
Technical properties
- Maximum service temperature: 1820 °C
- Al2O3: Approx. 96%
- Bulk density: 2.9 – 3 g/cm³
- Grain size: 0 – 5 mm
- Cold crushing strength after drying at 110 °C: Min. 650 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).
The values in the specification table are taken from the product datasheet. Contact the Pas Espadana technical team to select the right grade for your operating conditions.
