Cleanness of molten steel (T01)

• Subject Area: Metallurgical, Thermal and Thermomechanical Treatment of Materials
• Term: from 2016 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 169148856

In terms of their contribution and their functionality for removing non-metallic inclusions from the melt are researched novel replaceable filter systems in continuous casting of aluminum-killed steel (white strip grades). These carbon-bonded filter elements based on a) of foam ceramics with macro channels and b) Spaghetti structures with active and reactive functionalized coatings will be used. The filter components are characterizing by means of computed tomography before and after steel melt filtration. By using the tool of numerical simulations, the interactions between the filter structures, melt flow and inclusion particles are investigated in relation to the inclusion deposition on the filter surfaces. Application Partner is the company ThyssenKrupp Steel Europe AG.
