  1. 1. Desulphurization capacity of ladle slags for tool steels

    University essay from KTH/Materialvetenskap

    Author : Sixten Johansson; Elliot Nilstam; [2022]
    Keywords : ;

    Abstract : Steel quality is in direct correlation with the desulphurization process, meaning the removal of sulphur. A good desulphurization process greatly improves the mechanical properties among others, and is essential for obtaining higher quality steel. READ MORE

  3. 2. A literature study on measurement methods for calculating the FeO activity in slag

    University essay from KTH/Materialvetenskap

    Author : Rebecca Rosén; [2020]
    Keywords : ;

    Abstract : During the time we live in, climate change is more important than ever. HYBRIT, formed bySSAB, LKAB, and Vattenfall, is an initiative set out to make the steel production fossil free, by developing a novel process that produce direct reduced iron (DRI) using hydrogen as reagent. Electric arc furnaces (EAF) will then be employed to melt the DRI. READ MORE

  4. 3. 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

  5. 4. Alkali Circulation in the Blast Furnace - Process Correlations and Counter Measures

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

    Author : Joel Carlsson; [2018]
    Keywords : Alkali; coke; experimental blast furnace; top gas; mass spectrometry; multivariate analysis;

    Abstract : In blast furnace ironmaking one major challenge is to control and measure the alkalis circulating and accumulating in the blast furnace (BF). Alkali enter the BF with the primary raw material and will form a cycle where it is first reduced to metal at the lower parts forming gas. READ MORE
