  1. 11. Inclusion Motion under a Swirl Flow in the Continuous Casting Process and Wire Feeding in the Induction Furnace

    Författare :Ying Yang; Pär Jönsson; Seppo Louhenkilpi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inclusion motion; swirl flow; rotating magnetic field; electromagnetic swirl flow generator; full type; half type; submerged entry nozzle; mold; wire feeding; melting behavior; FeSiRE particle powder motion; induction furnace;

    Sammanfattning : The thesis includes the studies of two phenomena related to continuous casting. One subject is the inclusion motion in the submerged entry nozzle (SEN) and mold when using a swirl flow. The swirl flow is generated in a SEN by using an electromagnetic swirl flow generator (EMSFG). LÄS MER

  3. 12. Inclusion Behaviour under a Swirl Flow in a Continuous Casting Process

    Sammanfattning : A swirl flow generated in a submerged entry nozzle (SEN) can effectively improve a flow pattern and heat transfer in a continuous casting process by using the methods of “swirl blade type” and “electromagnetic type”. In order to obtain a further in-depth understanding with respect to the effect of a swirl flow on a continuous casting process, the inclusion behaviour in a SEN and a mold was studied in the present work.
