CERAMIC FOAM FILTER (Al2O3)
The Al2O3 based filters are intended in particular for filtering aluminium alloys and other nonferrous metals for foundry and metallurgical applications at the temperatures up to 1350 °C.
| Application | VUKOPOR® A ceramic foam filters are designed for filtration of aluminium and non-ferrous metal alloys in cast houses, particularly in primary and secondary processing of molten metal, as well as for filtration of castings in foundries. |
| Features | A typical feature of the structure of VUKOPOR® A ceramic foam filters is having a typical homogenous ceramic structure with a minimum of choked places on both the effective areas as well as inside the filter. These features, together with their resistance to chemicals used in metallurgical works and heat stability up to temperatures of 1350 °C, provide optimum conditions for filtration during the whole casting process. Their chemical composition, with adhesion forces active inside the filter ceramics, is ideal for capturing inclusions, particularly those on the basis of Al2O3. |

Note
The VUKOPOR® A filters for metallurgical applications are manufactured in a scale of square and round shapes with tapered sides providing their correct placement in horizontal filter bowls. Filters with an application in vertical position are manufactured in square or other special shapes without tapered sides.
All the types of filters are recommended to be equipped by sealing or expandable gaskets to fix them in the right position in linings and boxes. Metallurgical filters should be pre-heated before filtering and thus the maximum filtration capacity and pouring rate is achieved.
