Abstract of the dataset | In the present study a comprehensive investigation of the interactions between different molten high-silicon electrical steels (3 to 6 mass-% silicon) in aluminum killed condition with conventional and recycled MgO–C refractories is conducted. Immersion tests are carried out in accordance with the standards for testing and assessment of corrosion of refractories by liquids (DIN CEN/TS 15 418). Various mechanisms are defined and described which determine the corrosion of the refractory material in addition to infiltration. Scanning electron microscopy including energy dispersive X-ray spectroscopy (EDX analysis) is conducted to identify wear reactions, material transfers and reaction products at the contact zones and in the infiltration layers. The theoretically possible infiltration length is calculated and the limited applicability of the equations known from the literature is discussed. The formation of calcium sulfides and on other crucible reactions that take place are considered. These provide information and at the same time they influence the interactions between refractory materials and liquid steel. | |

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. | |
