  1. 1. An analytical method for quickly evaluating the performances of refractory alloys in sCO2 Brayton cycle applications

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

    Author : Jiaqi Yang; [2023]
    Keywords : ;

    Abstract : A rapid and effective analytical method has been developed to assess the performance of structural materials in sCO2 power cycle applications. This method combines a conjugate heat transfer model, considering constant heat flux boundary conditions, with a corresponding mechanical model. READ MORE

  3. 2. Testing of AblativeMaterials as a Protective Coating for Rocket Launch Pads

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

    Author : Gioele Daka; [2023]
    Keywords : Ablative Materials; Protective Coating; Rocket Launchpad; Refractory Materials; Oxyacetylene Torch; Slug Calorimeter; Ablativa material; Skyddande beläggning; Raketstartplatta; eldfast material; acetylensyrebrännare; kopparkalorimeter;

    Abstract : As the space market grows, demand for sites to host rocket tests and to launch satellites to orbit is expected to increase. During these activities, the launch infrastructure needs to withstand the extreme thermal and mechanical loads associated with the exhaust of a rocket engine. READ MORE

  4. 3. 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

  5. 4. The Impact of Water Addition on the Fracture Toughness of Pre-cast Refractory Materials

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Paulina Lindblad; [2022]
    Keywords : refractory materials; pre-cast elements; ceramics; fracture toughness; water addition; porosity; ceramic vortex finder;

    Abstract : A ceramic vortex finder (CVF) is the central pipe (gas outlet) of a gas cyclone, which is an important structural component within gas cyclone separation. Its main application is within high temperature processes, within the energy and cement industry where the atmosphere is highly abrasive and corrosive. READ MORE

  6. 5. A Pre-Assessment related to Refractory Waste Management in Sweden : Pre-study of the performance of MgO-C bricks made from recycled MgO-C refractory materials for use in steel production

    University essay from KTH/Materialvetenskap

    Author : Pranav Jagtap; [2021]
    Keywords : MgO-C brick; Refractory; Recycling; Reusing; Swedish Steel industries; MgO-C tegel; Eldfast; Återvinning; Återanvändning; Svensk stålindustri;

    Abstract : Steel industries consume refractory materials on a large scale. High temperature resistant refractory materials are essential for linings of the steelmaking vessels, to protect them from corrosive environments, high temperatures, molten steels and slags during transportation and steelmaking operations.
