Subject Area

Term
since 2024
Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 169148856
As part of the transfer project, an improved processing technology is to be developed in collaboration with our cooperation partner, in which the metal oxide formation for PbCaAl alloys is significantly reduced at the end of the melting and casting process. This increases the alloy's degree of purity and yield. At the same time, the amount of circulation material is reduced, which leads to an improvement of the energy and material balance. The reduction of the reoxidation of the lead alloy is realized by the controlled use of active and reactive filters to reduce the free oxygen content in the melting and casting process after refining. This is based on the results of the subprojects C06 and A01 of the SFB920, in which the purity of aluminium and steel melts was significantly improved by the use of active and reactive filters. The aim is to investigate how, with the help of suitable reactive filter materials, the finished lead alloy can be influenced in such a way that the reoxidation of the lead and the alloy components as well as undesirable phase formations can be minimized during the casting process. Furthermore, it is expected that the use of active filters will reduce the amount of finest non-metallic particles in the melt, which will additionally improve the purity of the alloy.
