  1. 1. Examination of a Damaged Slitting Knife using Scanning Electron Microscopy and Finite Element Simulations

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Love Öman; [2021]
    Nyckelord :slitting; slitting knives; damage; sem;

    Sammanfattning : At voestalpine Precision Strip AB, the slitting process is used frequently. Slitting is a commonly applied manufacturing technique during sheet metal processing that aims to split large coils of sheet metal into narrower widths. LÄS MER

    Sammanfattning : I Kiruna Kulsinterverk 4 (KK4) på LKAB i Kiruna tillverkas kulor av järnmalm, s.k. järnmalmspellets, av malmkoncentrat från ett anrikningsverk. På KK4 sker avvattning av järnmalmskoncentrat (slurry) med 10 st. LÄS MER

  4. 3. Development of a Profile Sample Cutter

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Maryam Tarik Hamad; [2020]
    Nyckelord :Blade geometry; vertical constraint; paper properties; paper slitting; Knivbladsgeometri; vertikal begränsning; pappersegenskaper; pappersskärning;

    Sammanfattning : The pulp- and paper industry is a key industry globally and stands for a production of 600 million tonnes pulp and paper worldwide with a total revenue of 400 billion dollars. Due to high quality requirements on paper, it is important to use instruments that control that the produced paper fulfill the promised requirements. LÄS MER

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

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Methods to create compressive stress in high strength steel components

    Kandidat-uppsats,

    Författare :Amir Abdin; Kaveh Feyzabi; Oskar Hellman; Henrietta Nordström; Dilman Rasa; Gustav Thaung Tolförs; Per-Olof Öqvist; [2018]
    Nyckelord :residual compressive stress; high strength steel; methods of inducing stress; analyzing stress;

    Sammanfattning : Residual compressive stresses can be used to increase the lifetime of parts under cyclic stress as they negate the applied tensile stresses that cause crack initiation and propagation in the material. The goal of this project was to investigate methods to induce stresses, their advantages and disadvantages as well as depth and magnitude of induced stresses, and also to find methods of analyzing the induced residual stresses.
