    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

  5. 4. On particles and slags in steel casting

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hadfield steel; deoxidation; grain size; inoculation; particles; viscosity; slag;

    Sammanfattning : Hadfield steel is widely accepted as one of the most important steel alloys utilized in industrial applications where high impact strength and wear resistance is required. Like in most metallic alloys used for component casting, the mechanical properties of Hadfield steel are directly connected with the microstructure of the material. LÄS MER

  7. 5. A study of solid and liquid inclusion separation at the steel-slag interface

    Författare :Jenny Strandh; Pär Jönsson; Robert Eriksson; Keiji Nakajima; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; mathematical modeling; inclusion separation; tundish; ladle; slag; steel-slag interface; physical properties; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : This thesis work aimed to provide a better knowledge of inclusion behavior at the steel-slag interface. All results are based on mathematical modeling of liquid and solid inclusion separation to the slag. The model descriptions of the inclusion transfer are based on the equation of motion at the system. LÄS MER
