  2. 1. Effect of swirling blade on flow pattern in nozzle for up-hill teeming

    Author : Line Hallgren; Pär Jönsson; Jonas Alexis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swirling flow; up-hill teeming; nozzle; casting; fluid flow; modelling; CFD; LDA.; Metallurgical process engineering; Metallurgisk processteknik;

    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.

  4. 2. Simulation of welding and heat treatment : modelling and validation

    Author : Henrik Alberg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : Many aerospace components with complex geometry are fabricated from smaller parts using joining techniques such as welding. Welding and the heat treatment which usually follows, can result in unwanted deformation and stresses. 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

  6. 4. 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

  7. 5. Whey protein adsorption and aggregation on modified stainless steel surfaces in relation to fouling
