  1. 1. Improving Availability of the Pelletization Process

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

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

    Abstract : 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. READ MORE

  3. 2. A DMAIC based framework to conduct Measurement System Analysis : A case study at Northvolt AB

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

    Author : Anshuman Manickam Vinoth; [2021]
    Keywords : ;

    Abstract : The aim of the project was to develop a framework for the execution of a Measurement System Analysis (MSA) which would help determine capability of a measurement system. The strategy behind carrying out this thesis has been to draft a framework which is based on the Define, Measure, Analyze, Improve, Control (DMAIC) model for a Measurement System Analysis (MSA) which would enable to gain a better understanding of the capability of measurement instruments that are used to control the quality of production processes of lithium-ion batteries.
