1. 16. Some aspects of recycling of rest products and slag foaming in the EAF during stainless steel production

   Författare :Arkadiy Davydenko; Andrey Karasev; Robert Eriksson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : An efficient stainless steel making industry is defined by different factors such as an efficient utilisation of energy in the Electric Arc Furnace (EAF). This requires a good by slag foaming practice and an utilisation of waste products from own production facilities. LÄS MER

3. 17. Analysis of fluoroalkyl sulfonamide (FASA) based copolymers : An indirect source of non-polymeric PFAS

   Författare :Felicia Fredriksson; Leo W. Y. Yeung; Anna Kärrman; Ulrika Eriksson; Robert Letcher; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFAS; FASA-based copolymers; fluorine mass balance; EOF; sludge; TF; earthworm; exposure;

   Sammanfattning : Per- and polyfluoroalkyl substances (PFAS) are an extensive group of anthropogenic compounds and are of global concern due to their negative effects on the environment and humans. Most environmental research reports non-polymeric PFAS, leading to a scarce understanding of polymeric PFAS, despite their large share on the global market. LÄS MER

4. 18. Evaluation of Non-Metallic Inclusions after Deformation and Their Effect on the Machinability of Steel

   Författare :SHUO GUO; Pär Jönsson; Andrey Karasev; Anders Tilliander; Robert Eriksson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel; Heat treatment; REM-treat steel; Ce modification; Chip breakability; weight distribution of chips Non-metallic inclusions; Deformation; Electrolytic extraction; stål; värmebehandling; REM-behandlade stål; Ce modifiering; spånbrytning; viktsdistribution av spån; icke-metalliska inneslutningar; deformation; elektrolytisk extraktion.; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : The presence of non-metallic inclusions (NMIs) have critical effects on both the mechanical properties and machinability of steels. In the present thesis, one focus is to study the characteristics of deformed sulfides (MnS) for a stainless steel (3R65) and a tool steel (42CrMo4). LÄS MER

5. 19. Optical Sensing With an Ordinary Mobile Phone

   Författare :Zafar Iqbal; Ingemar Lundström; Robert Björklund; Mats Eriksson; Magnus Willander; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : A major portion of the world’s population (≈ 80% of the total) lives in developing countries where lab instruments such as spectrophotometers are not widely available as their purchasing as well as maintenance is normally unaffordable. On the other hand, there are now around five billion mobile phone subscriptions worldwide and the current generation of standard mobile phones has several capabilities to perform user-defined analysis.

7. 20. Utilization of recovered lime-containing materials from pulp and paper industries as slag formers in stainless steel production

   Författare :Tova Jarnerud; Andrey Karasev; Pär Jönsson; Robert Eriksson; KTH; []
   Nyckelord :Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : In recent years, major efforts have been made to develop a more circular economy. The desire to reuse, remanufacture and recycle materials are important for the development towards a sustainable society. An extended lifespan of materials helps to reduce the amount of waste kept in landfills, as well as to reduce the extraction of natural resources. LÄS MER
