Abstract of the dataset | Vanadium is present in increased amounts in slag because of the production of certain steel grades and manufacturing technologies. In terms of circular economy, vanadium should be recovered from the slag, to use it again as an alloying element. Only a few studies on the extraction of vanadium have been carried out with synthetic slags. The core of this study is the characterisation of the extraction behaviour of vanadium by evaporation of its oxides from real iron and steel-making slags. The effect of various influencing factors on the evaporation behaviour of the slags should be demonstrated. The evaluation of the results should also take crucible wear into account. In addition, the phases formed in the slag are to be analysed. For this purpose, several melting tests are carried out with different blast furnace slags. To determine the vaporised components, the slags are analysed by an X-ray fluorescence spectrometer. | |

Project abstract | The focus of this doctoral project is to investigate the interaction of electrical steels (transformer steels), with high-silicate purity ladle slags free of running slag, with MgO-C products based on recyclates and environmentally friendly binders. The formation of ladle glaze can be studied by immersing a MgO-C product in a tracer-labelled slag during an immersion test. Investigations of the thermophysical properties of the liquid, killed/unkilled electrical steels and liquid slag as a function of temperature and SiO2 content, combined with thermodynamic calculations using FactSage software, make it possible to determine their influence on the interaction with MgO-C and ladle glaze formation. The influence of ladle glaze on the oxidic inclusion population, on the pick-up effect (undesirable increase of alloying elements) and reoxidation of the alloying elements is investigated by ladle glaze dissolution in the electric steel melt accompanied by chemical analysis and optical microscopy in combination with AFA (Automatic Feature Analysis) in the P-SEM. Research into the effect of the oxidic, non-metallic inclusions that form from ladle glaze on clogging in the spout nozzle based on recycled Al2O3-C is another focus. | |
