  2. 6. Heat transfer,inclusion characteristics and fluid flow phenomena during up-hill teeming

    Author : Robert Eriksson; KTH; []
    Keywords : Laser flash method; thermal diffusivity; slags; inclusions; water model; ingot casting; up-hill teeming;

    Abstract : Clean steel production requires good control of the sizedistribution and the composition of the inclusions at allstages of the steel making process. So far, there exists verylittle information on the behavior of the inclusion populationduring ingot casting of steel. READ MORE

  4. 7. Cementitious properties of steelmaking slags

    Author : Daniel Adolfsson; Bart Blanpain; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : The present study is directed towards the use of steelmaking slags as raw material for sulphoaluminate belite cement (SAB). Another important objective was to characterise the cementitious properties of phases in ladle furnace slag (LFS) specifically the calcium aluminates. READ MORE

  5. 8. Reactions in the Lower Part of the Blast Furnace with Focus on Silicon

    Author : Joel Gustavsson; Pär Jönsson; Leiv Kolbeinssen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blast furnace chemistry; ironmak ing; thermodynamics; silicon compounds; combustion; fuel injection; mass balance; slags; pig iron; gases; droplets;

    Abstract : 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. READ MORE

  6. 9. A Study of Parameters that Influence the Kinetics of the AOD Decarburisation Process

    Author : Patrik Ternstedt; Anders Tilliander; Ville-Valteri Visuri; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AOD; decarburization; steel; slags; composition; petrography; physical modeling; industrial plant trials; AOD; avkolning; stål; slagg; sammansättning; petrografi; fysikalisk modellering; industriella försök; Teknisk materialvetenskap; Materials Science and Engineering; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : This thesis focuses on the AOD process, which is an important metallurgical reactor in stainless steel production. To be more specific, the thesis is limited to study the decarburisation step, which is the first of three process steps in the AOD converter. READ MORE
