    Sammanfattning : Over the past centuries, a number of process routes for extraction of metal values from an ore or other resources have been developed. These can generally be classifiedinto pyrometallurgical, hydrometallurgical or electrometallurgical routes. LÄS MER

  7. 10. Some aspects of non-metallic inclusions during vacuum degassing in ladle treatment : with emphasize on liquid CaO-Al2O3 inclusions

    Författare :Young Jo Kang; Du Sichen; Takahiro Miki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-metallic inclusions; ladle refining; vacuum degassing; ladle glaze; spinel; SiO2 activity; agglomeration; cold model; open-eye; inclusion removal; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : The present thesis was to study non-metallic inclusions during vacuum degassing in ladle treatment. Emphasize was mostly given to liquid CaO-Al2O3 inclusions. A series of industrial experiments were carried out at Uddeholm Tooling AB, Hagfors, Sweden. To gain an insight into the industrial findings, laboratory investigations were also performed. LÄS MER
