  1. 1. Energy efficiency of smelting of scrap aluminium in HPDC facilities : Available and upcoming technologies

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Bogdan Radu Racsi; [2023]
    Nyckelord :high pressure die casting; HPDC; energy efficiency; cast house remelting; internal aluminium scrap; melting furnace; melting and holding furnace; drivers; barriers;

    Sammanfattning : The aluminium industry is anticipated to witness a surge in demand, with projectionsof a two to three-fold increase by 2050. Meeting environmental objectives andaddressing the growing emphasis on sustainability from both the industry andconsumers seeking eco-friendly products present significant challenges. LÄS MER

  3. 2. Life cycle assessment of flat glass and the implications of thinner and stronger glass

    Master-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Författare :Daniel Chima; [2023]
    Nyckelord :Soda-Lime Glass SLS ; Thermal Strengthening; Chemical Strengthening; Life Cycle Analysis.;

    Sammanfattning : In the production of glass, the addition of more cullet to the batch of glass and the reduction of the thickness of glass are means to reduce energy consumption and raw material usage. This contributes towards improved energy efficiency targets of the European Union. LÄS MER

  4. 3. 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

  5. 4. Theoretical Considerations and Experimental Observations on Heat Transfer in Hydrogen Direct Reduced Iron

    Master-uppsats, KTH/Materialvetenskap

    Författare :Felix Göttfert; [2023]
    Nyckelord :Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Heat Transfer; Thermal Conductivity; Thermophysical Properties; Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Värmeöverföring; Termisk konduktivitet; Termofysiska egenskaper;

    Sammanfattning : Steel has played an indispensable role in shaping our contemporary world  and will persist to play that role for the foreseeable future. However, the steel industry currently is responsible for 7% of the global CO2-emissions, primarily due to the conventional carbon-based reduction process of iron ore. LÄS MER

  7. 5. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    Master-uppsats, KTH/Materialvetenskap

    Författare :Hagen Christian Hagens; [2022]
    Nyckelord :Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Sammanfattning : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. LÄS MER
