  2. 1. Evolution of artificial defects during shape rolling

    Author : Mirjana Filipovic; Stefan Jonsson; Per-Olov Perä; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape rolling; wire rod rolling; artificial defects; defect evolution; surface cracks; porosity; FEM; high speed steel; stainless steel; Other materials science; Övrig teknisk materialvetenskap; Initiering och utveckling av defekter under spårvalsning;

    Abstract : Very often defects are present in rolled products. For wire rods, defects are very deleterious since the wire rods are generally used directly in various applications. For this reason, the market nowadays requires wire rods to be completely defect-free. Any wire with defects must be rejected as scrap which is very costly for the production mill. READ MORE

    Abstract : In the recent years, the demand for environmental friendly produced L-arginine has risen with the increasing number of applications for this amino acid in pharmaceuticals, nutraceuticals, cosmetics, animal feed and fertilizers. Members of the Corynebacteriaceae family are usually used for microbial L-arginine production. READ MORE

  5. 3. Surface and Inner Deformation during Shape Rolling of High Speed Steels

    Author : Kristina Nordén; Stefan Jonsson; Jan-Olov Perä; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical manufacturing engineering; Metallurgisk produktionsteknik;

    Abstract : Shape rolling is a common manufacturing process used to produce long products i.e. bars and wire. One of the problems that might occur during rolling is defect formation leading to rejection of the finished product. READ MORE
