  2. 6. 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

  4. 7. A Study of the Behavior of Foaming Slag in Steelmaking

    Author : Johan Martinsson; Du Sichen; Bjoern Glaser; Stuart Millman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The thesis presents a fundamental study on some aspects regarding foaming slag. In today’s society, the requirements on environmental impact and energy consumption are increasing. READ MORE

  5. 8. Energy and environmental optimization of some aspects of EAF practice with novel process solutions

    Author : Andrei Chychko; Seshadri Seetharaman; Lidong Teng; Shouyi Sun; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molybdates; slag foaming; steel alloying; EAF; carbonate decomposition; Materials science; Teknisk materialvetenskap;

    Abstract : The objective of the present thesis is to optimize the electric arc furnace (EAF) practice from an environmental view point. Two aspects that meet the requirements of the secondary steelmaking industries today, viz. READ MORE

  6. 9. Influence of alumina on the zinc slag fuming processes : an experimental study on physical properties and leaching behaviour of the generated fayalite-type slag

    Author : Sina Mostaghel; Heikki Kusti Jaikanen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical properties; Thermodynamic calculations; environmental properties; Sustainable extraction; Zinc fuming; Copper; Process Metallurgy; Processmetallurgi;

    Abstract : Recycling of secondary raw materials by non-ferrous metal producers is steadily increasing. These materials inevitably introduce various impurities to the production furnaces, which can change the chemical composition, and thereafter, the physical and chemical properties of the products and by-products of the operation.

  7. 10. Some aspects of recycling of rest products and slag foaming in the EAF during stainless steel production

    Author : Arkadiy Davydenko; Andrey Karasev; Robert Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : An efficient stainless steel making industry is defined by different factors such as an efficient utilisation of energy in the Electric Arc Furnace (EAF). This requires a good by slag foaming practice and an utilisation of waste products from own production facilities. READ MORE
