Registration of the filtration efficiency of active and reactive filter materials in contact with metal melts with the aid of a metal casting simulator (C01)

在第三个资助期内，将对基于环境友好型碳键合反应性过滤器的联合精炼方法进行调查；在坩埚中处理后，由于浮力的作用而未被除去的残留夹杂物将借助主动过滤器进行过滤。此外，还将系统地研究以铝酸钙等具有较高反应活性的氧化物为基础的反应性过滤器堵塞现象的记录。通过四种不同的程序方法，深入研究了沉积效率的动力学以及与钢熔体原位形成的内源夹杂接触的反应区形成。利用基于Al2O3-ZnO-C和Al2O3-ZnO-Al的功能过滤涂层对废钢进行按铜提纯将是一个新的研究热点。

Within the third funding period investigations of combined refining approaches based on environmental friendly carbon bonded reactive filters will take place; after the treatment in the crucible the left cluster of inclusions which were not removed due to the buoyancy forces will be filtrated with the aid of active filters. Further the registration of clogging phenomena of reactive filters based on oxide additions with higher reactivity such as calcium aluminates will be systematically investigated. By the use of four different procedural methods the kinetic of deposition efficiency as well as the formation of reaction zones in contact with in situ formed endogenous inclusions containing steel melts will be studied thoroughly. A new focus will be the refining of steel scrap according to copper with the aid of functional filter coatings based on Al2O3-ZnO-C und Al2O3-ZnO-Al.
