  2. 1. Studies of Steel/Slag Equilibria using Computational Thermodynamics

    Author : Lina Kjellqvist; Bo Sundman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel slag equilibria; thermodynamic modelling; thermodynamic assessment; CALPHAD; phase diagram; Thermo-Calc; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : The main focus in the present work concerns calculations on steel/slag equilibria. Thermodynamic software and databases are now powerful and accurate enough to give reliable results when applied to complex metallurgical processes. One example is the decarburization process of high alloyed steels. READ MORE

  4. 2. Thermodynamic modelling and assessment of some alumino-silicate systems

    Author : Huahai Mao; Bo Sundman; Gunnar Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermodynamic modelling; thermodynamic assessment; alumino-silicate system; slag; oxide system; CALPHAD; phase diagram; phase equilibrium; Thermo-Calc; compound energy formalism; ionic two sub-lattice liquid model; AlO2-1 species; Al2O3; CaO; MgO; SiO2; Y2O3; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : Alumino-silicate systems are of great interest for materials scientists and geochemists. Thermodynamic knowledge of these systems is useful in steel and ceramic industries, and for understanding geochemical processes. A popular and efficient approach used to obtain a self-consistent thermodynamic dataset is called CALPHAD. READ MORE

  6. 4. A Study of Slag/Metal Equilibrium and Inclusion Characteristics during Ladle Treatment and after Ingot Casting

    Author : Hamid Doostmohammadi; Pär Jönsson; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inclusions; thermodynamics; ladle treatment; vacuum; tool steel; bearing steel; slag; equilibrium; slag carryover; oxides; sulfides.; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : Today, there is a high demand on clean steel for high performance materialproperties. Thus, steel producers try to deliver a steel product with the highestquality and cleanliness to the market. The number of parameters that affect thesteel cleanliness may vary depending on the required material properties of thefinal product. READ MORE

  7. 5. 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
