2. 6. 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

   Abstract : Aluminum and steel have been the most produced metal and alloy, respectively, for many years. Their extensive use in various industries, their fundamental role in our everyday life, and their excellent recycling characteristics are the major driving forces for development of their production towards more sustainable processes.

5. 8. Formation of non-metallic inclusions and the possibility of their removal during ingot casting

   Author : Lars Ragnarsson; Sichen Du; Carlo Mapelli; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ingot casting; tool steel; inclusion; runner; refractory; erosion; casting powder; cold model; argon shroud; reoxidation; oxygen measurement; CFD; PIV; Metallurgical process engineering; Metallurgisk processteknik;

   Abstract : The present study was carried out to investigate the formation and evolution of non-metallic inclusions during ingot casting. Emphasize have been on understanding the types of inclusions formed and developed through the casting process and on the development of already existing inclusions carried over from the ladle during casting.

6. 9. A Mathematical and Experimental Study of Inclusion Behaviour at a Steel-Slag Interface

   Author : Jenny Wikström; Pär Jönsson; Lauri Holappa; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mathematical modeling; inclusion separation; tundish; ladle; slag; steel-slag interface; CSLM experiments; agglomeration; physical properties; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

   Abstract : The aim of this thesis work is to increase the knowledge of inclusion behavior at the steel-slag interface by mathematical modeling and in-situ Confocal Scanning Laser Microscope experiments. Mathematical models based on the equation of motion predicting liquid and solid inclusion behavior was first investigated. READ MORE

7. 10. Fluid inclusion studies of the Laisvall sandstone lead-zinc deposit, Sweden

   Author : Sten Lindblom; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The ore forming environment at Laisvall was characterized by a total salt content of 24 eq. wt-% NaCl with as much as 9 wt-% CaCl2. Its temperature fluctuated between 180°C and 120°C but generally decreased with time. The cementing mineral assemblage was deposited in the general sequence calcite, barite, fluorite, galena, sphalerite. READ MORE
