  1. 1. Skumning av ljusbågsugnsslagg vid tillverkning av rostfritt stål

    Master-uppsats, KTH/Materialvetenskap

    Författare :Sigrid Karlsson; [2023]
    Nyckelord :;

    Sammanfattning : Slaggskumning  är  ett  användbart  verktyg  för  att  optimera  processen  i  en ljusbågsugn. Traditionell slaggskumning baseras på en tillsats av syrgas och kolpulver, vilket skapar och reducerar oxider i slaggen. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

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

    Sammanfattning : 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. LÄS MER

  4. 3. Titanium vacancy diffusion in TiN via non-equilibrium ab initio molecular dynamics

    Master-uppsats, Linköpings universitet/Teoretisk Fysik

    Författare :Davide Gambino; [2016]
    Nyckelord :Titanium nitride; Ti monovacancy migration; Non-equilibrium ab initio molecular dynamics; Color diffusion algorithm; Statistics for stochastic events;

    Sammanfattning : Transition metal nitrides (TMNs) refractory ceramic materials are  widely employed as wear-resistant protective coatings in industrial machining as well as diffusion barriers inhibiting migration of metal impurities from the interconnects to the semiconducting region of electronic devices. TiN is the prototype of this class of materials and the most studied among TMNs. LÄS MER

  5. 4. Modeling of Heat Transfer in LDConverter (BOF) Lining

    Master-uppsats, KTH/Tillämpad processmetallurgi

    Författare :Georgina Jahan; [2012]
    Nyckelord :Mathematical Modeling; LD Converter; Refractory Lining; Ansys Fluent; Temperature Profile Distribution.;

    Sammanfattning : During the production of steel in the LD converter the refractory lining is exposed to high temperature emulsion of steel, slag and gas. It protects the steel body of the vessel to come in contact with the molten steel. LÄS MER
