2. 1. Influence of alumina on the zinc slag fuming processes : an experimental study on physical properties and leaching behaviour of the generated fayalite-type slag

   Author : Sina Mostaghel; Heikki Kusti Jaikanen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical properties; Thermodynamic calculations; environmental properties; Sustainable extraction; Zinc fuming; Copper; Process Metallurgy; Processmetallurgi;

   Abstract : Recycling of secondary raw materials by non-ferrous metal producers is steadily increasing. These materials inevitably introduce various impurities to the production furnaces, which can change the chemical composition, and thereafter, the physical and chemical properties of the products and by-products of the operation.

4. 2. A study of solid and liquid inclusion separation at the steel-slag interface

   Author : Jenny Strandh; Pär Jönsson; Robert Eriksson; Keiji Nakajima; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; mathematical modeling; inclusion separation; tundish; ladle; slag; steel-slag interface; physical properties; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Abstract : This thesis work aimed to provide a better knowledge of inclusion behavior at the steel-slag interface. All results are based on mathematical modeling of liquid and solid inclusion separation to the slag. The model descriptions of the inclusion transfer are based on the equation of motion at the system. READ MORE

5. 3. 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

6. 4. A Study of Slag/Metal Equilibrium and Inclusion Characteristics during Ladle Treatment and after Ingot Casting

   Author : Hamid Doostmohammadi; Pär Jönsson; Lauri Holappa; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inclusions; thermodynamics; ladle treatment; vacuum; tool steel; bearing steel; slag; equilibrium; slag carryover; oxides; sulfides.; Metallurgical process engineering; Metallurgisk processteknik;

   Abstract : Today, there is a high demand on clean steel for high performance materialproperties. Thus, steel producers try to deliver a steel product with the highestquality and cleanliness to the market. The number of parameters that affect thesteel cleanliness may vary depending on the required material properties of thefinal product. READ MORE
