  3. 8. Simulation of Rolling Mill to Computeand Improve Load Distribution

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Pontus Darth; [2021]
    Keywords : Finite Element; Simulation; Hot rolling mill; SSAB; Swerim AB; Roll Spallings; Spallings; Roll Failure;

    Abstract : This master thesis was done at Swerim AB in cooperation with SSAB and the Technical University of Luleå in the purpose of preventing spalling problems in hot rolling mills. Spallings are a fatigue damage that occurs on the rolls due to extreme loads and unfavorable conditions between the rolls in a mill. READ MORE

  4. 9. Thermal induced yellowing of peroxide bleached birch pulp

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Keywords : Accelerated ageing; Bleaching; Brightness reversion; Kraft pulp; pH; Yellowing;

    Abstract : Brightness reversion, also known as yellowing, is a well-known phenomenon which means that the brightness of paper products decreases during ageing. The name of this phenomenon is based on that paper products usually change in color towards yellow during ageing. READ MORE

  5. 10. Adapting the lead time tree model to include immaterial activities : Extending the lead time tree model to enable mapping, efficiency evaluation and waste identification in order fulfillment processes

    University essay from Högskolan i Jönköping/JTH, Produktionsutveckling

    Author : Mathilda Jonsson Egeman; [2019]
    Keywords : Administrative processes; Boundary object; Critical path; Engineer to order; Information flow mapping; Process mapping; Time-phased product structure;

    Abstract : Much research regarding efficiency in manufacturing industry has historically been focused on the material activities of the shop floor. However, companies that merely focus on material activities when trying to improve lead times, risk losing potential for improvements within immaterial activities such as planning, engineering, design, and purchasing, which often constitute the most time consuming parts of the order fulfillment processes.
