Abstract Scope |
Particles and inclusions are commonly removed from molten aluminium with the use of ceramic foam filters (CFF). The mechanical properties of CFFs are of great importance not only during transportation, storage and mounting, but also in view of securing the integrity of the filters during operation. Data on the compression strength of CFFs at room temperature are available in literature, but this is not the case for their performance under operating conditions. The main goal of the present study has been to measure the compression strength of conventional CFFs from different manufacturers, geometry and pore densities at elevated temperatures and different holding times both before and after being submerged into molten aluminium. Preliminary results indicates that at room temperature the compression strength were more or less unaffected, while a significant decrease was observed for the CFFs exposed to operating conditions. The effect of the holding time was inconclusive. |
