  1. 1. Investigation into Melting Characteristics of Hydrogen-Reduced Iron Ore Pellets

    University essay from KTH/Materialvetenskap

    Author : Hedda Pousette; [2019]
    Keywords : Iron Ore Pellets; Sulphur; Phosphorous; Slag; Hydrogen Gas; Järnmalmspellets; Svavel; Fosfor; Slagg; Vätgas;

    Abstract : What kinetic and thermodynamic characteristics are established in a melt of hydrogen-reduced iron ore pellets? The pellets contain self-fluxing slag components which upon melting form an initial slag. Refining capabilities of this slag, such as dephosphorization power, are investigated in a lab-scale vertical furnace. READ MORE

  2. 2. Reduction of a Detailed Thermal Model Lumped Parameters Approach for an OSV Induction Motor

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Luca Roggio; [2019]
    Keywords : ;

    Abstract : This thesis work is dealing with a detailed thermal model for an open self ventilated inductionmachine with lumped parameters approach. The model is entirely built using as referencespublished articles. The thermal network is tested using both MATLAB for calculating theparameters and SimScape for simulations and validation.

  3. 3. Electrolysis of chalcopyrite

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Regina Nemeth; [2018]
    Keywords : ;

    Abstract : Copper is one of the most important metals globally, due to its wide application range and excellent chemical properties. Today it is commonly produced from chalcopyrite concentrates by the pyrometallurgical route with high emissions of greenhouse gasses. READ MORE

  4. 4. Towards Sustainability Using Minimum Quantity Lubrication Technique and Nano-Cutting Fluids in Metal-Machining Processes

    University essay from KTH/Industriell produktion

    Author : Marta García Tierno; [2018]
    Keywords : ;

    Abstract : Sustainable manufacturing is making products from processes which have minimal environmental impact, energy and resource efficient, economically viable and safe for consumers and society as whole. Achieving sustainability in manufacturing would mean infusing sustainability methods on product process and system level. READ MORE

  5. 5. The Effect of Solidification time and Cooling rate on the Ultimate tensile Strength of Grey Cast Iron.

    University essay from KTH/Materialteknologi

    Author : Dinesh Sundaram; [2018]
    Keywords : Lamellar graphite iron; tensile properties; pearlitic properties; cooling rate; solidification time; Magmasoft.;

    Abstract : Tensile strength modelling is usually done to predict the mechanical properties of lamellargraphite iron considering microstructural features. This work attempts to create a simplifiedmodel incorporating cooling rate and solidification time without considering themicrostructural features. READ MORE
