Abstract of the dataset | The influence of V2O5 on the phosphorus partition between liquid crude steel and heterogenous basic oxygen furnace (BOF) slag with CaO/SiO2 = 4.2 was investigated at a temperature of 1600 C in a middle frequency induction furnace. Thereby the phosphorus transfer from ‘‘steel to slag’’ as well as from ‘‘slag to steel’’ was studied over a holding time of 60 minutes. The measured results were shown as phosphorus partition and phosphorus capacity and compared with the experimental values from the literature. It was found that V2O5 in highly basic BOF slags decreases phosphorus partition and phosphorus capacity. In addition, the resulting slags were investigated using a scanning electron microscope (SEM). | |

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. | |
