  4. 2. Some Aspects on Macroscopic Mixing in a Tundish

    Author : Chao Chen; Anders Tilliander; Lage Jonsson; Pär Jönsson; Guoguang Cheng; Seppo Louhenkilpi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; continuous reactor; tundish; tracer; macroscopic mixing; water model; CFD; turbulence models; inclusions removal; inclusions deposition; dynamic removal; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : Two aspects on macroscopic mixing in a continuous flow system – metallurgical tundish were studied. Specifically, 1) the first focus was on salt solution tracer mixing, which is important for tundish design from perspectives of tracer technology and Residence Time Distributions (RTD) as well as for the understanding of the macroscopic mixing in tundishes.

  5. 3. A Study of the Initial Mould Filling during Up-hill Ingot Casting

    Author : Line Hallgren; Pär Jönsson; Anders Tilliander; Seppo Louhenkilpi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swirling flow; up-hill teeming; nozzle; casting; fluid flow; modelling; CFD; LDA; swirl; ingot casting; filling; red eye;

    Abstract : The fluid flow in the mould during up-hill teeming is of great importance for the quality of the cast ingot and thereby the quality of the final steel products. At the early stage of the filling of an up-hill teeming mould, liquid steel flows with a high velocity from the runner into the mould. READ MORE

  6. 4. Solubility of hydrogen in slags and its impact on ladle refining

    Author : Jenny Hurtig; Sichen Du; Seppo Louhenkilpi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In the present thesis a study of the mechanisms of hydrogen control pickup during ladle treatment was undertaken. Previous studies showed that the presence of hydroxyl ions in the ladle slag resulteds in hydrogen transfer from the slag back into the steel bath. READ MORE
