    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blast furnace chemistry; ironmak ing; thermodynamics; silicon compounds; combustion; fuel injection; mass balance; slags; pig iron; gases; droplets;

    Sammanfattning : The thermodynamic conditions for the behaviour of silicon in the lower part of the blast furnace have been the focus of the thesis. More specifically, the influences of temperature, carbon activity, total gas pressure and Fe reoxidation on silicon have been studied. LÄS MER

  4. 3. Assessment of Body Composition Using Magnetic Resonance Imaging

    Författare :Joel Kullberg; Hans Frimmel; Tomas Gustavsson; Uppsala universitet; []
    Nyckelord :Bildanalys; Magnetic Resonance Imaging; Digital Image Processing; Segmentation; Morphology; Body Composition; Whole Body Imaging; Subcutaneous Adipose Tissue; Visceral Adipose Tissue; Anthropometry; Bildanalys;

    Sammanfattning : Methods for assessment of body composition allow studies of the complex relationships between body composition and the wellbeing of humans. The amount and distribution of adipose tissue is of great importance in these studies. LÄS MER

  5. 4. Influence of Ladle-slag Additions on BOF-Process Parameters

    Författare :Anders Dahlin; Pär G. Jönsson; Joel Gustavsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOF; slag formation; ladle slag; recycling; steel; composition; energy; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : The influence of ladle-slag additions on the BOF-process performance were investigated in plant trials. The aim of the study was to recycle ladle slag from secondary steelmaking to the LD-converter to save lime and improve the slag formation. LÄS MER
