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#)

该项目旨在技术开发和转让一种创新的金属过滤器概念。该创新基于陶瓷纤维的应用，陶瓷纤维既可与陶瓷泡沫过滤器结合使用，也可作为陶瓷泡沫过滤器的整体功能部分。后一种过滤系统可称为封装过滤系统。关于功能和过滤机制，过滤器将在环境条件下与CRC 920开发和应用的模型颗粒系统进行测试。扩大规模和应用测试是与行业合作伙伴georgherrmann Metallgießerei (GHM) GmbH， Freiberg共同完成的，提供了如何在生产现场修改铸造工艺的见解，以允许未来经济和可持续地实施新技术。

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.
