  1. 16. A SIMULATION WITH FINITE ELEMENTS TO MODEL STEEL SHEET SLITTING : A Master Thesis in Engineering Physics

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Adam Ahlgren Peters; [2019]
    Keywords : Finite element Method; steel; steel shearing; high performance steels; Finita Element Metoden; FEM; stål; stålklippning; höghållfasta stål; industriell ståltillverkning; spaltning;

    Abstract : A steel slitting process is simulated using FEM (Finite Element Method) in order to see potential defects along the edge in a steel sheet after it has been cut. The model's results were compared to microscope images of the steel sheet in order to verify accuracy. READ MORE

  3. 17. Towards a fossil free steel sector : Conditions for technology transfer of hydrogenbased iron and steel in Europe

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Amanda Öhman; [2019]
    Keywords : hydrogen-based iron and steel; direct reduction; industry decarbonisation; energy transition; Multi-level perspective; technology transfer; vätgasbaserat järn och stål; direktreduktion; fossilutfasning i industrin; energiomställning; multinivåperspektiv; tekniköverföring;

    Abstract : In order to meet the targets of the Paris Agreement, there is a need to significantly reduce emissions from energy-intensive industries, iron and steel included. One promising technology with the potential to reduce the emissions related to iron and steelmaking to basically none is direct reduction with fossil free hydrogen, which requires large amounts of fossil free electricity.

  4. 18. What If We Tilt the AOD? : Developing a numerical and physical model of a downscaled AOD converter to investigate flow behaviour when applying an inclination.

    University essay from KTH/Materialvetenskap

    Author : Serg Chanouian; [2019]
    Keywords : AOD; inclination angle; penetration depth; mixing time;

    Abstract : In a scrap based stainless steel plant the dominant process for carbon reduction is the Argon oxygen decarburisation process (AOD). The process goes through three steps: decarburisation, reduction and desulphurisation where the main challenge is to oxidise carbon to CO without oxidising the expensive chromium. READ MORE

  5. 19. Examination of Ancient Scandinavian Archaeological Findings : From Tortuna in Västerås, Sweden

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jacob Blinke; Evelynne Geiger; Amanda Edlund; [2018]
    Keywords : Forging; microstructure; steel manufacturing; Iron Ages; bloomery furnace; amulet rings; edge tools; horse cleat; Vickers hardness; Smide; mikrostruktur; ståltillverkning; järnåldern; blästerugn; amulettringar; eggverktyg; hästbrodd; Vickers hårdhet;

    Abstract : This study concerns the examinations of archaeological steel-objects from the Iron Ages, found in Tortuna outside Västerås, Sweden. Not many metallurgical analyses have been made on steel objects from the Iron Ages, most likely in order to preserve the findings. Therefore, very little knowledge about old steel materials exists.

  6. 20. Automated Classification of Steel Samples : An investigation using Convolutional Neural Networks

    University essay from KTH/Materialvetenskap

    Author : Björn Ahlin; Marcus Gärdin; [2017]
    Keywords : CNN; Automated classification; Inclusions; Steel; CNN; Automatisk klassificering; Inneslutningar; Stål;

    Abstract : Automated image recognition software has earlier been used for various analyses in the steel making industry. In this study, the possibility to apply such software to classify Scanning Electron Microscope (SEM) images of two steel samples was investigated. READ MORE
