  1. 1. Solvent Extraction Studies with Substituted Malonamides and Oligopyridines Influence of Structure and Chemical Properties on the Extraction Ability of Trivalent Actinides and Lanthanides

    Författare :Lena Spjuth; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lanthanide; malonamides; synergism; transmutation; oligopyridines; separation; solvent extraction; actinide; basicity;

    Sammanfattning : Separation and transmutation of spent nuclear fuel has been considered as a complement to direct disposal in a deep geological repository. The time needed for the waste to decay to natural background levels can be drastically decreased if the long-lived radionuclides, mainly the actinides, in the spent nuclear fuel are separated and transmuted to short-lived or stable nuclides.

  4. 3. A Study of EAF Austenitic and Duplex Stainless Steelmaking Slags Characteristics

    Författare :Saman Mostafaee; Margareta Andersson; Pär Jönsson; Nzotta Mselly; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EAF; Slag; Duplex steel; 304L stainless steel; Characterization; Microstructural evolution; Spinels; Basicity; Computational thermodynamics; Slag foaming; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Sammanfattning : The high temperature microstructure of the solid phases within the electric arc furnace (EAF) slag has a large effect on the process features such as foamability of the slag, chromium recovery, consumption of the ferroalloys and the wear rate of the refractory. The knowledge of the microstructural and compositional evolution of the slag phases during the EAF process stages is necessary for a good slag praxis. LÄS MER

  5. 4. A Study of EAF High-Chromium Stainless Steelmaking Slags Characteristics and Foamability

    Författare :Saman Mostafaee; Pär Jönsson; Margareta Andersson; Malin Selleby; Lauri Holappa; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
