  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

  2. 2. 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

  3. 3. 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.

  4. 4. Some Study related to Refractory Waste Management in Sweden : A move towards a greener and sustainable Swedish steel industry

    University essay from KTH/Materialvetenskap

    Author : Surbhi Shivaji Jogdand; [2020]
    Keywords : Refractory waste; Swedish steel producers; Recyclers; MgO-C bricks; Fines; MgO; Carbon elimination; Agriculture industry; Eldfast avfall; svenska stålproducenter; Återvinnare; MgO-C-tegel; Böter; MgO; Koleliminering; Jordbruksindustri.;

    Abstract : Decades  ago,  1  ton  of  steel  required  80  kg  of  refractory  material.  While  the  scenario  has completely changed over the years. Today, 1 ton of steel needs approximately 11 kg of refractory material   depending   on   the   steelworks. READ MORE

  5. 5. Secondary Steel Metallurgy Slag Design and MgO-C Refractory Implications : Theoretical and Practical Considerations

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

    Author : Hellgren Simon; [2019]
    Keywords : MgO-C; CaO-SiO2-Al2O3-MgO; Slag Design; Refractory Wear;

    Abstract : MgO-C based refractory materials, often used in secondary steel making, are exposed to variouswear mechanisms in its application. The wear could be divided into oxidative, chemical andabrasive categories, all behaving differently and all being influenced by different factors. READ MORE
