1. 1. Desulphurization capacity of ladle slags for tool steels

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Sixten Johansson; Elliot Nilstam; [2022]
   Nyckelord :;

   Sammanfattning : Steel quality is in direct correlation with the desulphurization process, meaning the removal of sulphur. A good desulphurization process greatly improves the mechanical properties among others, and is essential for obtaining higher quality steel. LÄS MER

3. 2. Effect of iron redox state on crystallization behaviour of Fayalite slags

   Master-uppsats, KTH/Materialvetenskap

   Författare :Paolo Mai; [2020]
   Nyckelord :Copper smelting; Slag; Magnesium Oxide; Iron redox equilibria; Optical basicity; Raman spectroscopy.; Smältning av koppar; Slagg; Magnesiumoxid; Järnredoxjämvikt; Optisk basicitet; Ramanspektroskopi.;

   Sammanfattning : In the copper smelting processes, the viscosity of the matte and the slag is an important factor for establishing efficiency. Impurities in the concentrates affect the viscosity not only by changing the melt structure but also by promoting precipitation of solid phase which sharply rises it. LÄS MER
