1. Influence of Ladle-slag Additions on BOF-Process Parameters
Abstract : The influence of ladle-slag additions on the BOF-process performance were investigated in plant trials. The aim of the study was to recycle ladle slag from secondary steelmaking to the LD-converter to save lime and improve the slag formation. READ MORE

2. Experimental studies to overcome the recycling barriers of stainless-steel and BOF slags
Abstract : This thesis presents several studies aimed at improving the recycling of steel slag. The studies are based on a first evaluation of the state-of-the-artof the recycling applications both with respect to their possibilities and limitations. READ MORE

4. Fundamental Experimental and Numerical Investigation Focusing on the Initial Stage of a Top-Blown Converter Process
Abstract : The aim of this thesis work is to increase the knowledge of phenomena taking place during the initial stage in a top blown converter. The work has been done in a few steps resulting in four different supplements. Water model experiments have been carried out using particle image velocimetry (PIV) technology. READ MORE

5. Modeling of Gas Flows in Steelmaking Decarburization Processes
Abstract : The purpose of the current study is to increase the understanding of different steelmaking processes at the decarburization stages by use of mathematical modeling. More specifically, two De-Laval nozzles from a VOD (Vaccum Oxygen Decarburization) process, which is used for producing stainless steels with ultra-low carbon grades, was investigated for different vessel pressures.
