Due to an ever increasing demand for cleaner, high quality steels, there is an increasing push for steelmakers to lower the non-metallic inclusion contents of the steel they produce. Understanding inclusion reactivity in steel is key in producing high quality steels at high production rates. Our current knowledge in controlling and predicting inclusion development during liquid steel processing is limited. In this study, spinel (MgAI204) inclusions of close to stoichiometric MgO.AI2O3 and known size distribution where added to the liquid steel bath prior to assessing their reactivity. The pO2 of the gas phase was controlled to 10-13 atm throughout the …

Steel cleanness is an important and growing research area driven by the demands to produce high quality steel. Lowering the inclusion content in steel is an important criterion for clean steel. It is therefore important to better understand the interaction between inclusions and slag to improve the removability of inclusions from liquid steel. For efficient inclusion removal the inclusions must attach/bond with the slag phase. The strength of the attachment can be characterised by the wettability of the slag on the inclusions. In this study, the dynamic wetting of ladle slags of the CaO-Al2O3-SiO2- MgO system on a solid spinel …
