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，对所有与铸造相关的主题进行了试验性铸造试验的计划、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。考虑了孕育剂和细化剂在熔融金属过滤过程中的行为，以及通过功能化过滤表面将它们引入材料的可能性。正在与分项目A07和T03合作，研究过滤故意生成的含铁金属间化合物相以降低二次铝合金中的铁含量。此外，在C06子项目的合作下，基于气孔敏感的铸造几何形状，研究了反应过滤器从铝熔体中去除氢的方法。

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.
