1. Growth and Removal of Inclusions During Ladle Stirring
Sammanfattning : The growth and removal of inclusions in stirred ladles hasbeen studied. First, the importance of different growthmechanisms suggested in the literature were studied. Simulationresults from a fundamental model of an induction-stirred ladlehave been used as input in the calculations. LÄS MER
2. Modeling of induction stirred ladles
Sammanfattning : Over the years numerous computational fluid dynamics models have been developed in order to study the fluid flow in gas and induction stirred ladles. These models are used to gain insight in the industrial processes used in ladle treatment of steel. A unified model of an induction stirred Ladle in two and three dimensions is presented. LÄS MER
3. Study of the slag-metal interaction in ladle treatment
Sammanfattning : .... LÄS MER
4. Influence of Stirring on the Inclusion Characteristics during Vacuum Degassing in a Ladle
Sammanfattning : 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). LÄS MER
5. Influence of fluid shear on primary nucleation of low molecular organic compounds in solution
Sammanfattning : In this project, two experimental systems have been set up to study the influence of fluid shear on primary nucleation. In the first set of experiments, in total about 3000 nucleation experiments have been done with butyl paraben/ethanol solutions, curcumin/ethanol solutions and m-hydroxybenzoic acid/1-propanol solutions in capped vials agitated with magnetic stir bars.
