  1. 1. Influence of Oxygen Enrichment on the Oxidation of a Magnetite Pellet Bed During Pot Furnace Induration

    Författare :Anna Eriksson; Charlotte Andersson; Hesham Ahmed; Timo Fabritius; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxygen enrichment; Magnetite pellet bed; Oxidation; Pot furnace; Induration; Fossil-free ironmaking; Process Metallurgy; Processmetallurgi;

    Sammanfattning : This study was motivated by the excess oxygen that likely results from the current transition to hydrogen-based Swedish steel production. The potential usability of large amounts of oxygen in a process gas for iron ore pellet induration could improve the process efficiency in terms of fuel consumption and productivity. LÄS MER

  3. 2. Investigation of Sintering Kinetics of Magnetite pellets during Induration

    Författare :TK Sandeep Kumar; Lawrence Hooey; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : One of the measures of development and economy of a nation is its per capita consumption of steel, and the demand is fulfilled by iron ore. In the context of increasing environmental constraints and ores becoming leaner and leaner, recycling and utilization of ore fines becomes necessary. LÄS MER

    Sammanfattning : In the era of globalization with increasing environmental awareness, sustainable utilization of the available resources is a necessity; iron ores are no exception. Pelletization, being one of the increasingly practiced agglomeration techniques for the iron ore fines as well as other solid wastes from steel plants. LÄS MER

  7. 5. Studies of human dendritic cells in the skin after antigen exposure

    Författare :Emily Bond; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Dendritic cells (DCs) act at the interface of innate and adaptive immunity. They are capable of inducing strong effector immune responses to invading pathogens, but also exert important functions in the maintenance of tolerance. LÄS MER
