  2. 11. Minimisation of Chromium Leaching from Low-Alloy Electric Arc Furnace Slag by Mineral Modifications

    Author : Ida Strandkvist; Fredrik Engström; Rainer Backman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slag; leaching; minerals; Process Metallurgy; Processmetallurgi;

    Abstract : Iron and steel are produced continuously as a vital part of modern life. The largest by-product of metal production is slag. Slag is an essential part of the production of steel since, in the furnace, the molten slag removes impurities from the metal. When the slag which consists of oxides, solidifies minerals form.

  4. 12. Study on some phenomena of slag in steelmaking process

    Author : Liushun Wu; Sichen Du; Carlo Mapelli; KTH; []
    Keywords : Slag viscosity; calcium fluoride; fluid viscosity with particles; mixture viscosity; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The present work is to study slag phenomena in steelmaking process. In order to attain thegoal, a number of high temperature experiments and simulation experiments were carried out. Four master slags were used to study the effect of CaF2 on slag viscosity. READ MORE

  6. 14. A Study of EAF High-Chromium Stainless Steelmaking Slags Characteristics and Foamability

    Author : Saman Mostafaee; Pär Jönsson; Margareta Andersson; Malin Selleby; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-chromium stainless steel; EAF; Slag; Microstructural characterization; Microstructural Evolution; Computational thermodynamics; Solid particles; Viscosity; Foamability; Basicity; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : A good slag practice is essential for production of a high-quality stainless steel. In addition, the electrical and material efficiency of the electric arc furnace (EAF) can considerably be improved by a good slag practice. The metallurgical properties of the slag are strongly influenced by its high-temperature microstructure. READ MORE

  7. 15. A Study on Vanadium Extraction from Fe-V-P Melts Derived from Primary and Secondary Sources

    Author : Mikael Lindvall; Du Sichen; Christiaan Pistorius; KTH; []

    Abstract : Vanadium extraction methods were developed for iron-vanadium-phosphorus (Fe-V-P) melts derived from processing of V-bearing titanomagnetites and steel slags. Studies on phase relationships of V slags were carried out to provide important understanding of the extraction processes. READ MORE
