  2. 1. An Experimental Study to Improve the Casting Performance of Steel Grades Sensitive for Clogging

    Author : Jennie Svensson; Pär Jönsson; Voicu Brabie; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Preheating; Decarburization; RBM; Clogging; SEN; Plasma sprayed coating; CaTiO3; YSZ; Continuous casting; Pilot plant trials; Industrial plant trials; Clean steel; Tundish; Non-metallic inclusions; MISS; Materials Science and Engineering; Teknisk materialvetenskap; Steel Forming and Surface Engineering;

    Abstract : In this study, the goal is to optimize the process and to reduce the clogging tendency during the continuous casting process. The focus is on clogging when the refractory base material (RBM) in the SEN is in contact with the liquid steel. READ MORE

  4. 2. The Submerged Entry Nozzle : A Study of how to Reduce Decarburization and Clogging

    Author : Jennie Svensson; Pär Jönsson; Voicu Brabie; Johan Björkvall; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science and Engineering; Teknisk materialvetenskap; Steel Forming and Surface Engineering;

    Abstract : During continuous casting the submerged entry nozzle (SEN) is one of the critical points. This since sequence casting is favourable, clogging of the SEN results in fever sequences or aborted castings. In this study the preheating of SEN has been evaluated at different steel plants.

  5. 3. Correlation effects in ionic perovskite crystals

    Author : Konstantinos Papadopoulos; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; muon spectroscopy; ion dynamics; correlated systems; multifunctional materials; spintronics; perovskites; magnetic order; solar cells;

    Abstract : Perovskites are a large family of versatile materials with favourable properties for spintronics and optoelectronics applications. The mineral CaTiO3 defines the archetypal crystal structure of perovskite materials with a general composition ABX3. READ MORE

  6. 4. Theoretical and Computational Studies of Strongly Correlated Electron Systems : Dynamical Mean Field Theory, X-ray Absorption Spectroscopy and Analytical Continuation

    Author : Johan Schött; Olle Eriksson; Igor Di Marco; Oscar Grånäs; Patrik Thunström; Tim Wehling; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : This thesis encompasses theoretical and computational studies of strongly correlated elec-tron systems. Understanding how electrons in solids interact with each other is of great im-portance for future technology and other applications. READ MORE
