12. A Study on the Population and Chemical Development of Non-Metallic Inclusions in the Tool-Steel Making Process
Abstract : The present work was to study the population and chemicalcharacterization of the inclusions at different steps of thetool steel making process based on industrial trialexperiments. The inclusion populations were found to increasewith ladle age (number of heats ladle being used) beforealuminium deoxidation and before casting. READ MORE

13. 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

14. 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

15. Effect of swirling blade on flow pattern in nozzle for up-hill teeming
Abstract : The fluid flow in the mold during up-hill teeming is of great importance for the quality of the cast ingot and therefore the quality of the final steel products. At the early stage of the filling of an up-hill teeming mold, liquid steel enters, with high velocity, from the runner into the mold and the turbulence on the meniscus could lead to entrainment of mold flux.
