3. 2. Alternative reducing agents in metallurgical processes : Experimental study of thermal characterization of shredder residue material

   Författare :Samira Lotfian; Noureddine Menad; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Sammanfattning : Coal used in metallurgical processes can participate in reduction reactions to produce metals and alloys from oxides. Base metals production leads to generation of slag, which contains valuable metals that can be recovered and recycled. There are several options to treat the slag, depending on the metal content in the slag. LÄS MER

   Sammanfattning : In the modern practice, a sustainable development strategy in a domain of wasteutilization is shifting its focus from a general completeness of recycling to a morespecific attention to efficiently utilize elements in the wastes. This is well-illustrated bythe steelmaking slag industries. LÄS MER

7. 5. Aspects on finite element simulation of sheet metal forming processes

   Författare :Ramin Moshfegh; Kjell Mattiasson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sheet metal forming process; Forming Limit Diagram; Metallurgical manufacturing engineering; Metallurgisk produktionsteknik;

   Sammanfattning : This thesis has focused on four different aspects of finite element simulation of sheet metal forming processes. Four substantial research areas are the development of a methodology for predicting the limiting strains in connection with the Forming Limit Diagram, the applicable mode of procedure for finite element simulation of the hydromechanical deep drawing process, the adaptive mesh refinement strategy based on gradients of the effective plastic stresses and strains; and the reliability and sensitivity assessments within sheet metal forming processes.
