  1. 1. Modeling for characterization of continuous casting simulator using CFD

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Filip Reineholm-Hult; [2023]
    Keywords : Continuous casting; CFD; computational fluid dynamics;

    Abstract : In order to improve the continuous casting process of steel, it’s important to have an understanding of the fuid mechanics of the casting process. As experiments on a real caster are usually impractical, both physical and numerical modeling are important for creating this understanding. READ MORE

  3. 2. Effect of iron redox state on crystallization behaviour of Fayalite slags

    University essay from KTH/Materialvetenskap

    Author : Paolo Mai; [2020]
    Keywords : Copper smelting; Slag; Magnesium Oxide; Iron redox equilibria; Optical basicity; Raman spectroscopy.; Smältning av koppar; Slagg; Magnesiumoxid; Järnredoxjämvikt; Optisk basicitet; Ramanspektroskopi.;

    Abstract : In the copper smelting processes, the viscosity of the matte and the slag is an important factor for establishing efficiency. Impurities in the concentrates affect the viscosity not only by changing the melt structure but also by promoting precipitation of solid phase which sharply rises it. READ MORE

  4. 3. Secondary Steel Metallurgy Slag Design and MgO-C Refractory Implications : Theoretical and Practical Considerations

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Hellgren Simon; [2019]
    Keywords : MgO-C; CaO-SiO2-Al2O3-MgO; Slag Design; Refractory Wear;

    Abstract : MgO-C based refractory materials, often used in secondary steel making, are exposed to variouswear mechanisms in its application. The wear could be divided into oxidative, chemical andabrasive categories, all behaving differently and all being influenced by different factors. READ MORE

  5. 4. Study on the suitability of a new method for in-situ viscosity measurement in industrial practice

    University essay from KTH/Materialvetenskap

    Author : Felicia Syrén; [2014]
    Keywords : Viscosity; Drag force; Sphere; Comsol model; Cold model experiments;

    Abstract : In this work cold model experiments in combination with Comsol modeling have been carried out to investigate the possibilities of a new method for industrial inline measurements of slag viscosities. The method aims at measuring the mass of the drag force as a sphere is dragged upwards in a liquid. READ MORE

  6. 5. Thermo-Physical Properties of Mould Flux Slags for Continuous Casting of Steel

    University essay from KTH/Materialvetenskap

    Author : Zhaleh Elahipanah; [2012]
    Keywords : Mould Flux Powders; Slags; Viscosity; Break Temperature; Mould; Continuous Casting; and Basicity;

    Abstract : Due to the high efficiency and productivity of continuous casting process, this method has been the most employed process to produce steel in past decades. The need to improve and optimize the finished product made it essential to gain more knowledge about the process, types of defects that may occur and the reasons for them. READ MORE
