There are several criteria which characterize melt cleanliness, e.g. hydrogen, alkali metal and the non-metallic inclusion content. Due to the increasing quality demand of materials for high end applications (e.g. the aerospace industry) melt cleanliness has to be improved. Beside the in-line melt treatment, which is a very important step for rising the melt quality, the content of impurities in casting/holding furnaces has to be reduced before to enhance efficiency of in-line operations. This paper describes the optimization possibilities for the casting furnace process especially the impeller gas purging treatment. Based on CFD-calculations, a methodology for the melt treatment of AA 7075 has been investigated and applied to the real process. Out of this, key factors can be derived and will be discussed.
