  1. 1. Skumning av ljusbågsugnsslagg vid tillverkning av rostfritt stål

    Master-uppsats, KTH/Materialvetenskap

    Författare :Sigrid Karlsson; [2023]
    Nyckelord :;

    Sammanfattning : Slaggskumning  är  ett  användbart  verktyg  för  att  optimera  processen  i  en ljusbågsugn. Traditionell slaggskumning baseras på en tillsats av syrgas och kolpulver, vilket skapar och reducerar oxider i slaggen. LÄS MER

  3. 2. Top Gas Blowing Technique to Prevent Slopping in Ladle and Basic Oxygen Steelmaking Process

    Master-uppsats, KTH/Materialvetenskap

    Författare :Abdullah Harazeen; [2022]
    Nyckelord :slag; slag foaming; slopping prevention; BOS; LD converter; ladle furnace; foaming index; and cold model experiment;

    Sammanfattning : In the steel industry, slag foaming plays a crucial role in many steel processes, given its positive impact on the thermal efficiency of the furnace and its life span. However, excessive foaming causes an overflow in the converter known as “slopping”. LÄS MER

  4. 3. Utilization of Pulp and Paper Waste Products in the Metal Industry : Initial testing of carbon-containing waste material briquettes

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

    Författare :Ingrid Johansson; Walter Deltin; [2018]
    Nyckelord :pulp and paper waste products; recycling; biosludge; fiber reject; drop test; slag foaming with briquettes; circular materials;

    Sammanfattning : Today, a huge part of waste products from pulp and paper industries ends up in landfill which is both economically and environmentally adversely. This report examines the possibilities of using those products as a slag foamer and fuel in different furnaces in the metal industry. The waste products contain valuable elements, especially carbon.

  5. 4. The effect of carbonaceous iron on slag foaming

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Josefin Svensson; [2018]
    Nyckelord :;

    Sammanfattning : The practise of slag foaming has become increasingly important within the scrap-based steelmaking, conducted in the electric arc furnace, due to its many advantages. In addition to increasing the efficiency in the furnace, the foaming protects the furnace equipment from wear and reduces noise pollution. LÄS MER

  7. 5. The Viability of Oxygen Gasblowing as a Foaming Slagsuppression System for Slopping Prevention in BOF-Processes

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Teodor Haglund; Joar Huss; [2016]
    Nyckelord :BOF; Foaming slag; Slopping prevention; Gas jet;

    Sammanfattning : Slopping in BOS-processes poses many problems, most significantly to work environmentand process effectiveness. Due to the current weaknesses in slopping prediction systems afoaming slag suppression system with immediate effect is needed to prevent slopping. LÄS MER
