  3. 2. Investigation of Interactions between Liquid Iron Containing Oxygen and Aluminosilicate Refractories

    Författare :Era Kapilasharmi; KTH; []
    Nyckelord :;

    Sammanfattning : The present work was initiated to investigate runnerrefractory corrosion by molten steel. The aim was to understandthe mechanism of inclusion formation during ingot casting. Thework is also of interest to other unit processes in steelmaking, where refractory corrosion and erosion are seriousproblems. LÄS MER

  4. 3. Some Fundamental Aspects Concerning Secondary Steelmaking

    Författare :Jimmy Gran; Du Sichen; Tooru Matsumiya; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The present thesis deals with some aspects concerning secondary metallurgy of steel where there is little or very inconsistent information in the literature. More specifically, it is devoted to the studies on high temperature phase equilibria in the Al2O3-CaO-MgO-SiO2 system, the formation of ladle glaze and the thermodynamics of magnesium in liquid iron.

  5. 4. Characterization of Impurities in Different Ferroalloys and Their Effects on the Inclusion Characteristics of Steels

    Författare :Yong Wang; Pär Jönsson; Andrey Karasev; Bart Blanpain; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ferroalloys; electrolytic extraction; metal surface; non-metallic inclusions; steel cleanliness; computational thermodynamics; ferrolegering; elektrolytisk extraktion; metallyta; icke-metalliska inneslutningar; stålrenhet; beräkningstermodynamik; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning :      Ferroalloys have become increasingly important due to their indispensable role in steelmaking. As the performance requirements of steel materials increase, it is necessary to have a better understanding of the impact of impurities in ferroalloys on the steel cleanliness. LÄS MER

  7. 5. Wettability and Agglomeration Characteristics of Non-Metallic Inclusions

    Författare :Changji Xuan; Pär Jönsson; Lauri Holappa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wettability; non-metallic inclusion; agglomeration mechanism; attraction force; complex deoxidation; particle addition; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : In this thesis, both the wettability and the agglomeration characteristics of non-metallic inclusions in liquid iron/steel were studied by using both experimental results and thermodynamic considerations. The mechanisms of the wettability of different types of inclusions were discussed. LÄS MER
