  1. 41. Semantic Segmentation of Iron Pellets as a Cloud Service

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Rosenvall Christopher; [2020]
    Keywords : AWS; Amazon Web Services; Iron Pellets; Iron Ore; Iron Ore Pellets; Cloud; Cloud Service; Semantic Segmentation; Machine Learning; SageMaker; Neural Networks; FCN; PSP; DeepLab;

    Abstract : This master’s thesis evaluates automatic data annotation and machine learning predictions of iron ore pellets using tools provided by Amazon Web Services (AWS) in the cloud. The main tool in focus is Amazon SageMaker which is capable of automatic data annotation as well as building, training and deploying machine learning models quickly. READ MORE

  2. 42. Investigate the track gauge widening on the Iron-ore line and suggest maintenance limits

    University essay from KTH/Spårfordon

    Author : Jesper Flodin; [2020]
    Keywords : ;

    Abstract : Iron ore export remains a major player in the Swedish economy to date, with 90% of all iron ore produced in Europe stemming from the relatively small northern country. A large amount of this ore is transported from the mines to harbours for world-wide freight on railways. READ MORE

  3. 43. Iron and Oxygen Isotope Signatures of Magnetite in Iron Ore of Kiruna Type

    University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

    Author : Malin Andersson; [2020]
    Keywords : IOA-deposits; magnetite; SIMS; EBSD; Fe- and O isotopes; laser fluorination;

    Abstract : Stable isotope analysis of iron and oxygen isotopes in magnetite of Kiruna-type from Sweden and Chile have been conducted to further the understanding of the formation, and advance the analysis methods of these deposits. For this, data from SIMS (secondary ion mass spectroscopy), EBSD (electron backscatter diffraction) and triple oxygen analysis (by laser fluorination) are used. READ MORE

  4. 44. Experimental study of the temperature profile in an iron ore pellet during reduction using hydrogen gas

    University essay from KTH/Materialvetenskap

    Author : Julia Brännberg Fogelström; [2020]
    Keywords : Iron ore; Iron oxide; Hematite pellet; Hydrogen reduction; Reduction; Intraparticle temperature; Temperature effect; Temperature profile; Järnmalm; Järnoxid; Hematitpellet; Vätgasreduktion; Reduktion; Invändig temperatur; Temperatureffekt; Temperaturprofil;

    Abstract : We are facing an important challenge, to reduce the greenhouse gas emissions to make sure that we limit global warming to 2 °C, preferably 1.5 °C. Drastic changes and developing new methods may be our only chance to keep global warming under 1.5 °C. READ MORE

  5. 45. Life cycle assessment of coal based direct-reduced iron production in India

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : SABARISH ELANGO; [2020]
    Keywords : ;

    Abstract : The production of iron through direct reduction (Direct-Reduced Iron; DRI) involves the use of natural gas or coal to reduce iron ore to iron through carbothermic reactions at a temperature below its melting point, negating the need for a blast furnace as otherwise required. In India, around 25% of iron is produced through direct reduction. READ MORE
