  1. 1. Numerical Study on Steel Flow and Inclusion Behavior during a Ladle Teeming Process

    Författare :Peiyuan Ni; Pär Jönsson; Lage Jonsson; Mikael Ersson; Jonas Alexis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; numerical simulation; inclusion behavior; CFD; clogging; deposition.;

    Sammanfattning : Inclusions in molten steel have received worldwide concern due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the deoxidation process, reoxidation by air and/or slag due to an entrainment during steel transfer, and so on. LÄS MER

  3. 2. Modeling the behavior of inclusions in plastic deformation of steels

    Författare :Chunhui Luo; KTH; []
    Nyckelord :Inclusion; Steel; Plastic deformation; Void; Rolling; Forging; Finite element; Mesomechanical approach;

    Sammanfattning : This doctoral thesis presents a modeling method fordemonstrating the behavior of inclusions and their surroundingmatrix during plastic deformation of steels.Inclusions are inescapable components of all steels. LÄS MER

  4. 3. Fatigue Anisotropy in Forged Components

    Författare :Cornelius Temmel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inclusion Cluster; Low Sulfur; Machinability; Inclusion; Manganese Sulfide; Quenching Crack; Forging; Isotropic Quality; Steel; Anisotropy;

    Sammanfattning : Ever-growing requirements on combustion engine efficiency of motor vehicles demand increasing service loads in powertrain components. Optimization of component material is therefore inevitable. A major detriment with many forged transmission components is their anisotropic mechanical behavior, not least during cyclic loading.

  5. 4. Everyday life in preschool – Swedish and international approaches

    Författare :Frida Åström; Eva Björck; Mats Granlund; Lena Almqvist; Thomas Moser; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Early Childhood Education and Care ECEC ; preschool practices; participation; engagement; inclusion; environment; free play; systematic observation; behavior count; person-oriented; quality;

    Sammanfattning : Background: The ultimate outcome of inclusive Early Childhood Education and Care (ECEC), with the focus on everyday life in preschool in this dissertation, is child participation, i.e., being there and being engaged while being there. LÄS MER

  7. 5. 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
