  1. 1. Improving Availability of the Pelletization Process

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Emil Andreasson; Pontus Åhman; [2022]
    Nyckelord :Availability; Predictive Maintenance; Pelletization; Statistical Process Control; Refractory Material; DMAIC;

    Sammanfattning : The Grate-Kiln-Cooler process is a commonly used method of sintering during iron ore pelletization, where the pellets are formed, dried, and hardened. The pellets are oxidized in the rotating Kiln, turning magnetite (Fe3O4) to hematite (Fe2O3), making the pellets attain suitable metallurgical attributes for further processing. LÄS MER

  3. 2. Towards Understanding slag build-up in a Grate-Kiln furnace : A study of what parameters in the Grate-Kiln furnace leads to increased slag build-up, in a modern pellet production kiln

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Oscar Olsson; Uno Österman; [2022]
    Nyckelord :Grate-kiln; Slag; Interpretable machine learning; IID; independent and identically distributed; Kulsinter; pellets; slagg; slag; LKAB;

    Sammanfattning : As more data is being gathered in industrial production facilities, the interest in applying machine learning models to the data is growing. This includes the iron ore mining industry, and in particular the build-up of slag in grate-kiln furnaces. LÄS MER

  4. 3. Wear of Grate Plates

    Master-uppsats, KTH/Materialvetenskap

    Författare :Johan Martinsson; [2014]
    Nyckelord :Grate; plate; wear;

    Sammanfattning : This report describe the wear of the protruding areas on the sides of the grate plates in the grate-kiln process in the hematite pellet production in LKAB, Kiruna. The steel plates are exposed to a hostile environment with heat cycles and corrosive atmosphere. LÄS MER
