1. 1. A study of slag-steel-inclusion interaction during Ladle treatment

   Författare :Johan Björklund; Pär Jönsson; Voicu Brabie; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ladle treatment; steel; slag; inclusions; ladle; refining; vacuum; tool steel; oxide activity; slag models; oxygen; equilibrium; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

   Sammanfattning : The thesis is based on two supplements with two major objectives. In the first supplement equilibrium top slag-steel bulk and inclusions-steel bulk were investigated by comparison between calculated and measured oxygen activity values. This was done by applying different oxide activity models for slags combined with thermodynamic calculations. LÄS MER

4. 3. Environmental System Analysis of Waste Management : Experiences from Applications of the ORWARE Model

   Författare :Anna Björklund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste MSW ; waste management; waste management planning; model; environmental systems analysis; life cycle assessment LCA ; substance flow analysis SFA ; substance flows; environmental impact; energy; uncertainty; Chemical engineering; Kemiteknik;

   Sammanfattning : Waste management has gone through a history of shiftingproblems, demands, and strategies over the years. In contrastto the long prevailing view that the problem could be solved byhiding or moving it, waste is now viewed as a problem rangingfrom local to global concern, and as being an integral part ofseveral sectors in society.

5. 4. Real estate performance

   Författare :Kicki Björklund; KTH; []
   Nyckelord :;

   Sammanfattning : This dissertation consists of five papers addressing variousreal estate performance issues (see full titles in italicsbelow). The dissertation is empirical in nature and the dataused in most of the empirical sections consist of figures forincome-producing property returns. LÄS MER

7. 5. Thermodynamic Aspects on Inclusion Composition and Oxygen Activity during Ladle Treatment

   Författare :Johan Björklund; Pär Jönsson; Margareta Andersson; Leiv Kolbeinsen; KTH; []
   Nyckelord :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;

   Sammanfattning : 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.
