  2. 1. Steel converter slag as an oxygen carrier

    Author : Fredrik Hildor; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Steel converter slag; Biomass; Oxygen carrier; LD slag; Oxygen carrier aided combustion; Chemical looping;

    Abstract : Thermal conversion of fuels can be used to produce heat and power in addition to chemicals. In order to be aligned with climate targets, it is necessary that such systems do not emit carbon dioxide to the atmosphere. Carbon capture and storage (CCS) can be used together with fuel conversion systems to prevent CO2 from entering the atmosphere. READ MORE

  4. 2. A Study on Vanadium Extraction from Fe-V-P Melts Derived from Primary and Secondary Sources

    Author : Mikael Lindvall; Du Sichen; Christiaan Pistorius; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vanadium; V; V2O5; V2O3; ferrovanadium; vanadiferous; titaniferous; titanomagnetites; magnetite; spinel; slag; experimental; free; spinel; converter; LD; BOF; solubility; equilibrium; selective; oxidation; hibonite; karelianite; Al2O3; CaO; SiO2; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Vanadium extraction methods were developed for iron-vanadium-phosphorus (Fe-V-P) melts derived from processing of V-bearing titanomagnetites and steel slags. Studies on phase relationships of V slags were carried out to provide important understanding of the extraction processes. READ MORE

  5. 3. Study on the dissolution of lime and dolomite in converter slag

    Author : Tengfei Deng; Sichen Du; Takeshi Yoshikawa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dissolution; lime; limestone; dolomite; converter slag;

    Abstract : In the present study, the dissolution mechanism and rate of lime, limestone and dolomite in converter slag was studied. Lime dissolution in stagnant slag was studied first and dissolution of lime, limestone and dolomite under forced convection were carried out by new experimental setup. READ MORE

  6. 4. Fundamental Experimental and Numerical Investigation Focusing on the Initial Stage of a Top-Blown Converter Process

    Author : Mikael Ersson; Pär Jönsson; Stein-Tore Johanssen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical modeling; top-blown converter; BOF; CFD; Thermodynamics; slag; dynamic simulations; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : The aim of this thesis work is to increase the knowledge of phenomena taking place during the initial stage in a top blown converter. The work has been done in a few steps resulting in four different supplements. Water model experiments have been carried out using particle image velocimetry (PIV) technology. READ MORE

  7. 5. Influence of Ladle-slag Additions on BOF-Process Parameters

    Author : Anders Dahlin; Pär G. Jönsson; Joel Gustavsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOF; slag formation; ladle slag; recycling; steel; composition; energy; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : The influence of ladle-slag additions on the BOF-process performance were investigated in plant trials. The aim of the study was to recycle ladle slag from secondary steelmaking to the LD-converter to save lime and improve the slag formation. READ MORE
