  1. 11. Densities and viscosities of slags : modeling and experimental investigations

    Författare :Mikael Persson; Seshadri Seetharaman; Rob Brooks; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; density; nolar volume; thermodynamics; enthalpies; model; slags; oxide melts; viscosity; mould flux; continuous casting; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : The present dissertation describes part of the efforts directed towards the development of computational tools to support process modeling. This work is also a further development of the Thermoslag software developed in the Division of Materials Process Science, KTH. LÄS MER

  3. 12. Some Aspects of Improving Initial Filling Conditions and Steel Cleanliness by Flow Pattern Control Using a Swirling Flow in the Uphill Teeming Process

    Författare :Zhe Tan; Pär Jönsson; Ersson Mikael; Stein Tore Johansen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; uphill teeming; ingot casting; flow pattern; swirl blade; TurboSwirl; realizable k-ε model; CFD.;

    Sammanfattning : The flow pattern has widely been recognized to have an impact on the exogenous non-metallic inclusion generation in the gating system and mold flux entrapment in the uphill teeming process. Thus, a well-controlled flow pattern during the teeming process can improve the quality of ingots and further increase the yield during steel production. LÄS MER

  4. 13. The influence of microstructure on the crack initiation and propagation in Al-Si casting alloys

    Författare :Toni Bogdanoff; Salem Seifeddine; Ehsan Ghassemali; Anders E.W. Jarfors; Johan Moverare; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminum-Silicon alloys; scanning electron microscopy; material characterization; fatigue performance; digital image correlation;

    Sammanfattning : For reducing the CO2 footprint in many industrial fields, the goal is to produce lighter components. The aluminium-silicon (Al-Si) cast alloys are promising candidates to fulfill these goals with a high weight-to-strength ratio, good corrosion properties, excellent castability, and recyclable material.

  5. 14. Rheocasting of aluminium alloys : Process and components characteristics

    Författare :Mostafa Payandeh; Anders E. W. Jarfors; Magnus Wessén; Helen Atkinson; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheocasting; aluminium alloy; RheoMetal TM process; microstructural characteristics; component properties and performance; robust design process;

    Sammanfattning : Semi-Solid Metal (SSM) casting is a promising technology offering an opportunity to manufacture net-shape, complex geometry metal components in a single operation. However, the absence of foundry guidelines and limited design data for SSM casting makes it challenging to predict the performance of both process and components. LÄS MER

  7. 15. On the influence of Si on anodising and mechanical properties of cast aluminium alloys

    Författare :Baiwei Zhu; Caterina Zanella; Salem Seifeddine; Peter Leisner; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-Si based casting alloys; anodising; corrosion protection; mechanical properties; Al-Si-baserade gjutningslegeringar; anodisering; korrosionsskydd; mekaniska egenskaper;

    Sammanfattning : The combination of two cost-effective processes, i.e. casting and anodising, would be an interest for the aluminium component applications. However, there are some obstacles in the application of anodising on cast Al alloys. LÄS MER
