Active and reactive filtration of steel- and aluminum-melts during the dead mould casting of thin – and thick wall components (S03)

在服务项目S03中，针对所有铸造相关主题进行实验性铸造测试的规划、组织和执行。对新开发的过滤系统和过滤材料进行了热机械稳定性测试。孕育剂和晶粒细化剂在熔融金属的过滤过程中的行为被认为是以及通过功能化的过滤器表面引入到材料中的可能性。与子项目A07和T03合作，正在研究有意产生的含铁金属间相的过滤，以减少再生铝合金的铁含量。此外，从铝熔体中去除氢的反应过滤器是研究合作与子项目C06的基础上孔隙敏感的铸件几何形状。

In service project S03, the planning, organization and execution of experimental casting tests are carried out for all foundry-relevant topics. New developed filter systems and filter materials are tested for their thermo-mechanical stability. The behavior of inoculants and grain refiners during the filtration of molten metals is considered as well as the possibility of introducing them via functionalized filter surfaces into the material. In cooperation with subprojects A07 and T03, the filtration of intentionally generated iron-containing intermetallic phases to reduce the iron content of secondary aluminum alloys is being investigated. Furthermore, the removal of hydrogen from aluminum melts by reactive filters is investigated in cooperation with subproject C06 on the basis of a pore-susceptible casting geometry.
