2. 1. Numerical Study on Steel Flow and Inclusion Behavior during a Ladle Teeming Process

   Author : Peiyuan Ni; Pär Jönsson; Lage Jonsson; Mikael Ersson; Jonas Alexis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; numerical simulation; inclusion behavior; CFD; clogging; deposition.;

   Abstract : Inclusions in molten steel have received worldwide concern due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the deoxidation process, reoxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE

4. 2. A Study on Particle Motion and Deposition Rate : Application in Steel Flows

   Author : Peiyuan Ni; Pär Jönsson; Lage Jonsson; Mikael Ersson; Stein Tore Johansson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; continuous casting; non-metallic inclusion behavior; particle deposition; nozzle clogging; numerical simulation.;

   Abstract : Non-metallic inclusions in molten steel have received worldwide attention due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the de-oxidation process, the re-oxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE

5. 3. Heat transfer,inclusion characteristics and fluid flow phenomena during up-hill teeming

   Author : Robert Eriksson; KTH; []
   Keywords : Laser flash method; thermal diffusivity; slags; inclusions; water model; ingot casting; up-hill teeming;

   Abstract : Clean steel production requires good control of the sizedistribution and the composition of the inclusions at allstages of the steel making process. So far, there exists verylittle information on the behavior of the inclusion populationduring ingot casting of steel. READ MORE

6. 4. A Study on the Thermal State of Steelmaking Ladles

   Author : Björn Glaser; Du Sichen; Petrus Christiaan Pistorius; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steelmaking ladle; refractory; thermal conductivity; transient hot wire method; slag; peheating;

   Abstract : In the present thesis a study on the thermal state of steelmaking ladles was undertaken. The transient hot wire method was verified for thermal conductivity measurements on metallurgical slags and applied to ladle slag measurements. Temperature measurements on ladles in an industrial environment were carried out. READ MORE

7. 5. Fluid Flow Phenomena, Inclusion Characteristics and some Heat Transfer Phenomena during Filling of an Ingot Mmold

   Author : Robert Eriksson; KTH; []
   Keywords : up-hitt teeming; model powder; inclusions; plant trials; thermal diffusivity; fluid flow; physical modeling;

   Abstract : Clean steel production requires a good understanding of theinclusion characteristics at all stages of the steelmakingprocess. So far there exist little information about theformation and evolution of inclusions during the filling ofingot molds. READ MORE
