1. 1. Modeling of Cold Pilgering of Tubes

   Författare :Yağız Azizoğlu; Lars-Erik Lindrgren; Denis Sornin; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold pilgering; finite element method; tube forming; tool elasticity; roll flattening; Material Mechanics; Materialmekanik; Steel Forming and Surface Engineering;

   Sammanfattning : Cold pilgering is a challenging tube forming process in terms of modeling due to the complexity in kinematic of tools, friction condition and material behavior. The process development has mostly been based on simple formulas and costly full-scale tryouts. LÄS MER

3. 2. Some aspects on lubrication and roll wear in rolling mills

   Författare :Mohammed Tahir; KTH; []
   Nyckelord :strip rolling; lubricants; environment; roll wear modeling. Production campaigns; regression analysis;

   Sammanfattning : The thesis is focused on lubricants and roll wear in striprolling.Regarding lubricants, the possibility of introducing newones, which are less detrimental towards environment, isstudied in laboratory scale. This is done for cold rolling,both of an Al- alloy and a low carbon steel. LÄS MER
