  3. 2. A Study on the Influence of Steel, Slag or Gas on Refractory Reactions

    Författare :Sune Jansson; Pär Jönsson; Lauri Holappa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : During the production of steel the oxide inclusion content partly depends on the reaction of the melt with the furnace lining, the ladle lining and the pouring system. The refractory material may be eroded by the molten steel and slag as well as corroded through chemical reactions with the slag and molten steel and the deoxidation products. LÄS MER

  4. 3. Fractures of the distal radius : Factors related to radiographic evaluation, conservative treatment and fracture healing

    Författare :Albert Christersson; Sune Larsson; Bengt Sandén; Karl-Åke Jansson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Distal radius fractures (DRFs) are one of the most common injuries encountered in orthopaedic practise. Such fractures are most often treated conservatively, but surgical treatment has become increasingly common. LÄS MER

  5. 4. A study of slag corrosion of oxides and oxide-carbon refractories during steel refining

    Författare :Ismail Kasimagwa; Pär Jönsson; Sune Jansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The use of ceramic material as refractories in the manufacturing industry is a common practice worldwide. During usage, for example in the production of steel, these materials do experience severe working conditions including high temperatures, low pressures and corrosive environments. LÄS MER

  7. 5. A study on the Submerged Entry Nozzels (SEN) respecting clogging and decarburization

    Författare :Arashk Memarpour; Pär Jönsson; Sune Jansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory; SEN; Clogging; REM; Coating; glaze; alkaline; Refractory; ZrSi2; Graphite; Alumina; Oxidation; Al2O3-C; ZrO2-C; MgO-C; decarburization; reaction mechanism; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The submerged entry nozzle (SEN) has been used to transport the molten steel from tundish to the mould. The main purpose of the SEN usage is both to prevent oxygen and nitrogen pick-up by molten steel and to achieve the desired flow condition in the mould. LÄS MER
