  3. 22. Modeling drying of iron ore pellets

    Författare :Anna-Lena Ljung; Graham Nathan; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Iron ore pellets are a highly refined product supplied to the steel making industry for use in blast furnaces or direct reduction processes. The use of pellets offers many advantages such as customer adopted products, transportability and mechanical strength yet the production is time and energy consuming. LÄS MER

  4. 23. Recycling of Steel Grinding Swarf via Production of Iron Chloride Coagulants for Water Treatment

    Författare :Thomas Ottink; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water Treatment; Ferric Chloride; Hazardous waste; Leaching; Hydrometallurgy;

    Sammanfattning : Grinding swarf is a hazardous waste generated in the manufacturing industry when making products out of iron and steel. Annually 10-12 million tons are generated worldwide, and these numbers are projected to grow with steel production and industrialization of developing countries. LÄS MER

  5. 24. Carbides in martensitic medium carbon low alloyed tool steels studied with small angle scattering techniques, electron microscopy and atom probe tomography

    Författare :Erik Claesson; Peter Hedström; Hans Magnusson; Erik Offerman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low alloyed tool steel; Martensite; Small angle scattering; Scanning transmission electron microscopy; Energy dispersive x-ray spectroscopy; atom probe tomography; Scanning precession electron diffraction; Precipitation; carbides; Tempering.; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Medium carbon low alloyed tool steels are used today in various areas to shape plastics, nonferrous metals, and steels, and they are crucial in the manufacturing industry. To be effective, tool steels must be strong and tough, and have high wear resistance and temperature stability. LÄS MER

  7. 25. 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
