  1. 1. Practical investigation of mixing phenomena by physical modelling : Scaling criteria applied for bottom gas-stirred water modelling of metallurgical vessels

    University essay from KTH/Materialvetenskap

    Author : Simon Garpenquist; Carl Erik Sebastian Lindfors; [2021]
    Keywords : Ladle furnace; Water model; Mixing time; Modified Froude number; Scaling criteria; Scaling factors; Skänkmetallurgi; Vattenmodell; Blandningstid; Froude s modifierade tal; Skalnings kriterier; Skalnings faktorer;

    Abstract : Gas stirring is currently the most commonly used method of homogenizing liquid steel in commercial processes. However, due to the harsh environment during the process, physical models built out of e.g. plexiglass have been used to easier understand the complex phenomenon occurring in the process. READ MORE

  3. 2. Optimisation of the bottom stirring praxis in a LD-LBE converter : Investigations and tests on phosphorous removal, nitrogen as stirring gas, and slopping

    University essay from Uppsala universitet/Oorganisk kemi

    Author : José Aguirre Castillo; [2015]
    Keywords : LD; BOS; Bottom Stirring; Phosphorous; Steel making; Nitrogen;

    Abstract : The LD-process, called after the cities Linz and Donawitz, is used to convert pig iron into crude steel by blowing oxygen on top of the pig iron. A LD-LBE converter, Lance Bubbling Equilibrium, also stirs the melt trough a bottom stirring system. READ MORE

  4. 3. A desulphurization study of hot metal at SSAB Europe Luleå with added bottom stirring of nitrogen gas

    University essay from KTH/Materialvetenskap

    Author : Mattias Edvartsen; [2015]
    Keywords : desulphurization; desulfurizing; removal of sulfur; steel; bottom stirring.;

    Abstract : This bachelor degree project is about determining the impact that additional bottom stirring may have on the desulphurization process at SSAB Luleå. During one week of field work steel samples were collected from 39 different heats. READ MORE
