16. A study of solid and liquid inclusion separation at the steel-slag interface
Abstract : This thesis work aimed to provide a better knowledge of inclusion behavior at the steel-slag interface. All results are based on mathematical modeling of liquid and solid inclusion separation to the slag. The model descriptions of the inclusion transfer are based on the equation of motion at the system. READ MORE

18. Formation and Chemical Development of Non-metallic Inclusions in Ladle Treatment of Steel
Abstract : The present study was carried out to investigate theformation and chemical development of non-metallic inclusionsduring ladle treatment of steel.To begin with, an investigation of the deoxidation processand the impact of aluminium addition was carried out. For thispurpose, a new experimental setup was constructed. READ MORE

19. Influence of Stirring on the Inclusion Characteristics during Vacuum Degassing in a Ladle
Abstract : Steel cleanliness as a function of stirring practice during vacuum degassing treatment have been investigated in industrial studies at the steel plants of SSAB Special Steels in Oxelösund and Uddeholm AB in Hagfors. The cleanliness was examined with regards to the contents of sulphur, nitrogen and large inclusions (>10µm). READ MORE

20. Numerical Study on Steel Flow and Inclusion Behavior during a Ladle Teeming Process
Abstract : Inclusions in molten steel have received worldwide concern due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the deoxidation process, reoxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE
