    Sammanfattning : This thesis investigates optimization of the control of electrical and thermal equipment by using FEM and CFD modeling in combination with dynamic simulation models. The thesis focuses on the production of electrical strips and the control system with the aim of reducing losses and improving magnetic properties. LÄS MER

  3. 2. Some aspects on lubrication and roll wear in rolling mills

    Författare :Mohammed Tahir; KTH; []
    Nyckelord :strip rolling; lubricants; environment; roll wear modeling. Production campaigns; regression analysis;

    Sammanfattning : The thesis is focused on lubricants and roll wear in striprolling.Regarding lubricants, the possibility of introducing newones, which are less detrimental towards environment, isstudied in laboratory scale. This is done for cold rolling,both of an Al- alloy and a low carbon steel. LÄS MER

  7. 5. Study and empirical modelling of recrystallisation annealing of martensitic chromium steel strip by means of EBSD

    Författare :Sorin Ionescu-Gabor; KTH; []
    Nyckelord :EBSD; Etching; Metallography; Cold Rolling; Recrystallisation annealing;

    Sammanfattning : Recrystallisation annealing, a repeated heat treatment between different stages of cold rolling of martensitic chromium steel strip, is successful when neither high rolling forces nor wear of the working rolls occur during the subsequent cold rolling. Mechanical properties as tensile strength, yield, elongation or hardness have been, by tradition, the criteria that described the quality of the annealing process. LÄS MER
