  2. 21. Slag, Steel, Ladle and Non-metallic Inclusions Equilibria in an ASEA-SKF Ladle Furnace

    Author : Kamrooz Riyahimalayeri; Malin Selleby; Johan Björkvall; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clean steel; Top slag; Non-Metallic Inclusions; Oxides; Vacuum Degassing; Deoxidation; Desulphurization; Equilibrium; Computational Thermodynamics; Scanning electron microscopy;

    Abstract : This study explores the possibility of prediction and modification of some of the physicochemical properties of non-metallic inclusions by considering top slag-steel-ladle equilibria in an ASEA-SKF ladle furnace. To test the reliability of an available computational thermodynamic computer program, the first sub project was done. READ MORE

    Abstract : Background: In recent years, there has been a reported increase in organizations relocating to Activity-based Flexible Offices (A-FOs) worldwide. The idea of A-FOs is to offer work conditions suitable for the workforce’s tasks and individual preferences. READ MORE

  5. 23. A Study on the Reaction between MgO Based Refractories and Slag-Towards the Development of Carbon-free Lining Material

    Author : Huijun Wang; Sichen Du; Stuart Millman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MgO refractory; lining material; carbon-free; clean steel; ladle glaze; slag penetration; dissolution mechanism; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : In present thesis, the fundamental studies on the reaction between MgO based refractories and slag were undertaken for the development of a carbon-free bonding MgO lining material. Alumina was selected as a potential binder material. Due to MgO-Al2O3 chemical reaction, the developed refractory was bonded by MgO·Al2O3 spinel phase. READ MORE
