PhD Thesis

During the BOF steel production, up to 300 kg of slag are produced per tonne of steel. In addition to the classic slag formers CaO, SiO2 and Al2O3, the slag also consists largely amounts of iron oxides. Also, other metals such as chromium, manganese and titanium are contained in their oxidic form. The aim of the PhD-study is to increase the efficiency of the value chain in steel production by separating CaO, SiO2 and Al2O3 from iron and the other metal oxides through selective crystal growth and slag modification.
