  1. 21. Analys och underhåll av komponenter i tuff kemisk miljö

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Elektronik

    Författare :Patrik Axelsson; [2021]
    Nyckelord :;

    Sammanfattning : Examensarbetet som rapporten redovisar utfördes i ett av Volvo Group Truck Operation:s (GTO) gjuterier på motorfabriken i Skövde. Här används sandgjutning för att tillverka komponenter till lastbilsmotorer av gjutjärn. I gjutprocessentillverkas sandkärnor enligt Epoxy-SO2-metoden. Sandkärnorna hanteras av robotar i slutna celler. LÄS MER

  3. 22. A Pre-Assessment related to Refractory Waste Management in Sweden : Pre-study of the performance of MgO-C bricks made from recycled MgO-C refractory materials for use in steel production

    Master-uppsats, KTH/Materialvetenskap

    Författare :Pranav Jagtap; [2021]
    Nyckelord :MgO-C brick; Refractory; Recycling; Reusing; Swedish Steel industries; MgO-C tegel; Eldfast; Återvinning; Återanvändning; Svensk stålindustri;

    Sammanfattning : Steel industries consume refractory materials on a large scale. High temperature resistant refractory materials are essential for linings of the steelmaking vessels, to protect them from corrosive environments, high temperatures, molten steels and slags during transportation and steelmaking operations.

  4. 23. Utredning av sprickorsakerna i infästningarna till kylelement

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Ammie Bäckström; Nicklas Werner; [2021]
    Nyckelord :;

    Sammanfattning : The assignment handed out by Cementa in Skövde is to investigate why crack formation and propagation emerge in the fixed attachment clamps and propose solutions against it. The fixed attachments are part of the cooling element suspension, used in the cement production to cool the material coming out of the oven. LÄS MER

  5. 24. Corrosion Resistant Multi-Component Coatings for Hydrogen Fuel Cells

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Jakob Steneteg; [2021]
    Nyckelord :Coatings; Hydrogen Fuel Cells; Multi-Component; High Entropy Alloys; Corrosion Resistance;

    Sammanfattning : Multi-component coatings and high entropy alloys have in recent years attracted great interest for research, since they have shown to exhibit properties greater than the com- ponents of their parts. Today’s climate challenges requires transitioning from fossil fuels to renewable energy sources which demands use of new technology and new innovations. LÄS MER

  7. 25. Barrier properties of model coatings using recycled iron oxide pigment

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Nathalie Hagenfjärd; [2021]
    Nyckelord :Organic coatings; Iron oxide pigment; EIS; Barrier properties;

    Sammanfattning : The aim of this study was to compare the barrier properties of organic coatings with the same polymer matrix but different types of iron oxide particles, commercial and recycled. The work was carried out for the company SSAB with the aim of investigating whether the pigment Merox ferric oxide, which is produced in-house at the company during the pickling process, can be used and replace commercial iron oxide pigment.
