  1. 11. Some Study related to Refractory Waste Management in Sweden : A move towards a greener and sustainable Swedish steel industry

    Master-uppsats, KTH/Materialvetenskap

    Författare :Surbhi Shivaji Jogdand; [2020]
    Nyckelord :Refractory waste; Swedish steel producers; Recyclers; MgO-C bricks; Fines; MgO; Carbon elimination; Agriculture industry; Eldfast avfall; svenska stålproducenter; Återvinnare; MgO-C-tegel; Böter; MgO; Koleliminering; Jordbruksindustri.;

    Sammanfattning : Decades  ago,  1  ton  of  steel  required  80  kg  of  refractory  material.  While  the  scenario  has completely changed over the years. Today, 1 ton of steel needs approximately 11 kg of refractory material   depending   on   the   steelworks. LÄS MER

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

    Master-uppsats, KTH/Materialvetenskap

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

    Sammanfattning : 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. LÄS MER

  4. 13. Design and Simulation of Terahertz Antenna for Spintronic Applications

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Nils Eivarsson; Malin Bohman; Emil Grosfilley; Axel Lundberg; [2020]
    Nyckelord :spintronics; terahertz; THz; antenna; simulation; COMSOL multiphysics;

    Sammanfattning : Spintronics is a spin-electronic field where the electron spinangular momentum, in conjunction with charge, is used to read andwrite information in magnetic sensors and logic circuits, e.g. hard disk drive (HDD), magnetic random access memory (MRAM) and broadband TeraHertz (THz) emitters.

  5. 14. 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

  7. 15. Optimizing the sealing of tubular heating elements

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Victor Almblad; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Tubular heating elements, produced by Backer AB are today commonly used, serving as systems for intelligent heating in automotive, medical and household industries. Tubular heating element consists of a mantle, resistance wire, electrical insulation (magnesium oxide) and a sealing. LÄS MER
