Abstract of the dataset | Phosphorus partition data from Ukrainian integrated steel plants are analyzed, focusing on the influence of parameters such as the basicity (CaO/SiO2), optical basicity, tapping temperature, and the contents of (FeO), (MgO), and (Al2O3) in the slag. It is found that the phosphorus partition decreases with increase in tapping temperature and increases with the optical basicity. An increase in the phosphorus partition (P)/[P] followed by a decrease with increase of (CaO/SiO2) are observed. It is found that the optimal value, break point at which phosphorus partition changes its dependence to opposite, has a direct dependence on tapping temperature. At (CaO/SiO2) =1.9–2.1, (P)/[P] increases linearly with increasing (FeO). However with higher value of (CaO/SiO2) the breaking point when (P)/[P] starts to decrease with increase in (FeO) is noticed. Thereby the optimal value of (FeO) decreases with increasing tapping temperature. In case of (Al2O3) there is only decreasing of (P)/[P] with all (CaO/SiO2) and tapping temperatures. Moreover, the effect of (MgO) varies with (CaO/SiO2). These industrial results are supported by thermodynamic simulations using FactSage 8.1 and aligned with existing results from the literature. | |

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. | |
