  2. 16. Thermodynamic Aspects on Inclusion Composition and Oxygen Activity during Ladle Treatment

    Author : Johan Björklund; Pär Jönsson; Margareta Andersson; Leiv Kolbeinsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ladle treatment; thermodynamics; inclusions; steel; slag; equilibrium; ladle treatment; vacuum; oxide activity; oxygen activity.; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : Two industrial studies and one set of lab scale trials have been done. In addition, a theoretical study has been done. The main focus has been on non metallic inclusion composition during the ladle refining operation in industrial steel production. Sampling has been done together with careful inclusion determination.

  7. 20. An Operational View on Foaming and Slopping Control in Top-blown BOS Vessels

    Author : Mats Brämming; Henrik Saxén; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Slag formation plays a decisive role in all steelmaking processes. In top-blowing Basic Oxygen Steelmaking (BOS) i.e., in the LD process, an emulsion consisting of liquid slag, dispersed metal droplets, undissolved particles and solid precipitates will, together with process gases, form an expanding foam.
