  2. 1. Growth and Removal of Inclusions During Ladle Stirring

    Author : Mats Söder; KTH; []
    Keywords : inclusions; ladle; gas-stirring; induction-stirring; secondary refining; bubble flotation;

    Abstract : 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. READ MORE

  4. 2. Modeling of induction stirred ladles

    Author : Mayur Pal; Pär Jönsson; Pavel Ramirez Lopez; KTH; []
    Keywords : induction ladle; electromagnetic; Lorentz forces; magnetic stirrer; magnetic diffusion; Navier-Stokes; FEM;

    Abstract : 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. READ MORE

  5. 3. Growth and removal of inclusions during ladle refining

    Author : Mats Söder; Pär Jönsson; Hae-Geon Lee; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Meteorology; inclusions; steel; ladle; cluster growth; modelling; Meteorologi; Meteorology; Meteorologi;

    Abstract : The overall purpose of this thesis work has been to further our understanding of the growth and removal of inclusions in gas- and induction-stirred ladles. The primary focus has been on alumina inclusions.Growth mechanisms were studied using data from fundamental mathematical models of gas- and induction-stirred ladles. READ MORE

  7. 5. Some aspects of non-metallic inclusions during vacuum degassing in ladle treatment : with emphasize on liquid CaO-Al2O3 inclusions

    Author : Young Jo Kang; Du Sichen; Takahiro Miki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-metallic inclusions; ladle refining; vacuum degassing; ladle glaze; spinel; SiO2 activity; agglomeration; cold model; open-eye; inclusion removal; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : The present thesis was to study non-metallic inclusions during vacuum degassing in ladle treatment. Emphasize was mostly given to liquid CaO-Al2O3 inclusions. A series of industrial experiments were carried out at Uddeholm Tooling AB, Hagfors, Sweden. To gain an insight into the industrial findings, laboratory investigations were also performed. READ MORE
