  1. 6. Weight Optimization of Vertical-Axis Wind Turbine Blades constructed in Swedish Fossil Free Steel : With respect to fatigue life time

    Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Johannes Hall; Albin Larsson; [2023]
    Nyckelord :VAWT; Wind Turbine Blade; SSAB; Fossil-Free; Weight Optimization; Topology Optimization; Sizing Optimization; NACA 0018; STRENX 1300; Abaqus; Tosca Structure; VAWT; Vindturbinblad; SSAB; Fossilfritt; Viktoptimering; Topologioptimering; Size-Optimering; NACA 0018; STRENX 1300; Abaqus; Tosca Structure;

    Sammanfattning : Wind turbines have been utilized for centuries to harness energy from the wind. Commercial wind turbine blades are typically made from composite materials, which are difficult to recycle, leading to blades ending up in landfills at the end of their lifecycle. Additionally, these materials contribute to microplastic pollution. LÄS MER

  2. 7. Increased build rate by laser powder bed fusion of SSAB steel powder

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Colin Daly; [2023]
    Nyckelord :Additive manufacturing; Laser powder bed fusion; Build rate; Steel powder;

    Sammanfattning : SSAB has built a pilot gas atomization facility looking to expand their expertise of steel into the metal powder and additive manufacturing industry. Laser powder bed fusion is an additive manufacturing method that melts and fuse metal feedstock powder together layer by layer using a high intensity laser. LÄS MER

  3. 8. Optical Emission Spectroscopy Pulse Distribution Analysis on Steel Production Samples : Accuracy, sample variation, spread in different samples and steel grades/routes

    Master-uppsats, KTH/Materialvetenskap

    Författare :Paulo Urrea Molina; [2023]
    Nyckelord :;

    Sammanfattning : This thesis work aimed to contribute to the development of online characterization techniques for non-metallic inclusions in steelmaking. The study focused on assessing the precision and accuracy of the optical emission spectroscopy pulse distribution analysis (OES/PDA) technique using asreference light optical microscope (LOM) and scanning electron microscope(SEM).

  4. 9. Minskat CO2 avtryck i råstål genom en ökad andel skrot i konvertern

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Elin Karlström; [2023]
    Nyckelord :BOF; scrap rate; CO2 emissions; carbon footprint; post combustion; Råstål; stålskrot; koldioxidavtryck; koldioxidutsläpp; konverter; efterförbränning;

    Sammanfattning : Stålindustrin är kraftigt energi och utsläppsintensiv och står för upp till cirka 7% av de globala 𝐶𝑂2-utsläppen. Den huvudsakliga utsläppskällan utgörs av masugnsprocessen där järnmalm reduceras till råjärn med hjälp av fossilt kol i den malmbaserade processvägen. LÄS MER

  5. 10. Transforming into a learning organization? A study of challenges and conditions that leaders face when supporting the development of a learning organization

    Magister-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Ruta Karlsson; Lina Fahlborg; [2022]
    Nyckelord :Learning Organization; Organizational Learning; Leadership Practices; Management; Learning Activities; Business and Economics;

    Sammanfattning : The concept of learning organizations is one of the most popular concepts within management research. There seems to be a continuous need for learning in organizations as it equips companies to survive rapid changes in the internal and external organizational environment as well as competition.
