  2. 1. Mass transfer and slag-metal reaction in ladle refining : a CFD approach

    Author : Eva Ramström; Du Sichen; Mselly Nozotta; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reoxidation; desulphurisation; CFD; ladle treatment; model; Other materials science; Övrig teknisk materialvetenskap;

    Abstract :   In order to optimise the ladle treatment mass transfer modelling of aluminium addition and homogenisation time was carried out. It was stressed that incorporating slag-metal reactions into the mass transfer modelling strongly would enhance the reliability and amount of information to be analyzed from the CFD calculations.

  5. 3. A model of pH and redox buffer depletion in waste landfills

    Author : James Crawford; KTH; []
    Keywords : ;

    Abstract : The geochemical processes governing the release of heavymetal contaminants from solid waste materials have been studiedexperimentally and modelled using a mass balance approach. Theaim of the modelling work was to develop calculation tools thatcan be used to predict the release rate of heavy metals fromwaste heaps or landfills. READ MORE

  6. 4. Studies on High Alumina Blast Furnace Slags

    Author : Amitabh Shankar; Seshadri Seetharaman; Rob Boom; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : In the present work, viscosities and sulphide capacities of high alumina blast furnace slags were investigated. The systems investigated were four component CaO-SiO2-MgO-Al2O3 quaternary system, CaO-SiO2-MgO-Al2O3-TiO2 and CaO-SiO2-MgO-Al2O3-CaF2 quinary systems. READ MORE

  7. 5. Experimental and modelling studies of the thermophysical and thermochemical properties of some slag systems

    Author : Lijun Wang; Seshadri Seetharaman; Kuo-Chih Chou; Miyuki Hayashi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Abstract : In order to optimize the metallurgical processes it is necessary to improve the understandings of the industrial slag properties, which include thermophysical and thermochemical properties. In the present study Mass Triangle Model was applied to predict these properties. READ MORE
