   Sammanfattning : Chromium is an important alloying element in stainless steel but also environmentally harmful element. A number of mineralogical phases present in the slag matrix can contain chromium and lead to chromium leaching. LÄS MER

3. 2. A study of an autogenous slag for steel production with consideration of possible vanadium extraction

   Författare :Amanda Vickerfält; Pär Jönsson; Du Sichen; Johan Martinsson; Takahiro Miki; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : The thesis discusses the use of the autogenous slag that forms from the residual oxides present in hydrogen reduced iron (H-DRI) pellets during melting. The studies are motivated by a better understanding of how H-DRI affect the steelmaking operations. LÄS MER
