1. A study of slag-steel-inclusion interaction during Ladle treatment
Abstract : The thesis is based on two supplements with two major objectives. In the first supplement equilibrium top slag-steel bulk and inclusions-steel bulk were investigated by comparison between calculated and measured oxygen activity values. This was done by applying different oxide activity models for slags combined with thermodynamic calculations. READ MORE

2. Thermodynamic Aspects on Inclusion Composition and Oxygen Activity during Ladle Treatment
Abstract : Two industrial studies and one set of lab scale trials have been done. In addition, a theoretical study has been done. The main focus has been on non metallic inclusion composition during the ladle refining operation in industrial steel production. Sampling has been done together with careful inclusion determination.

5. The Effect of Ladle Treatment on Steel Cleanness in Tool Steels
Abstract : The aim of the present work was to get an overview of the steel cleanness in tool steel. Plant trial studies of three steel grades were done with different focuses.Firstly the change of the inclusion characteristics during the vacuum degassing in the ladle was looked upon. READ MORE
