Increase in purity of aluminum melts by applying the principle of pre-coat and body feed filtration using encapsulated ceramic deep-bed filters and ceramic fibers (T05#)

The project aims at the technology development and transfer of an innovative metal filter concept. The innovation bases on the application of ceramic fibers, which are used either as precoat-body feed filter aid in combination with a ceramic foam filter or as an integral functional part of a ceramic foam filter. The latter filter system can be called encapsulated filter. Concerning function and filtration mechanisms, the filter will be tested at ambient conditions with a model particle system, developed and applied in the CRC 920. The scale-up and application tests are done jointly with the industry partner Georg Herrmann Metallgießerei (GHM) GmbH, Freiberg, providing an insight how the casting process has to be modified in a production site to allow the future economic and sustainable implementation of the new technology.
