  1. 1. Roll pass design for improved flexibility and quality in wire rod rolling

    Författare :Conny Eriksson; Ulf Ståhlberg; Magnus Jarl; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; wire rod; roll pass design; working range; productivity; swedish wire rod mills; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The thesis treats roll pass design in wire rod rolling of stainless steel for sequences and series built up by two-symmetrical grooves. It is focused on predicting rolling flexibility, also called working range, as well as product quality. For analysing the flexibility a computer program has been developed. LÄS MER

  2. 2. Alternatives to pickling : preparation of carbon and low alloyed steel wire rod

    Författare :Peter Gillström; Magnus Jarl; Sven-Erik Lundberg; Tarras Wanheim; Örebro universitet; []
    Nyckelord :Mechanical descaling; shot blasting; pickling; steel wire rod; wear; drawing; Mechanical engineering; Maskinteknik; Maskinteknik; Mechanical Engineering;

    Sammanfattning : A well established method for scale removal on hot rolled wire rod is pickling. To avoid pollution problems, the wire rod can be mechanically descaled. By this method, the removed scale can be recirculated to the blast furnace. In batch pickling considerable energy is necessary; e. LÄS MER

  3. 3. Tribology in Metal Working

    Författare :Maria Nilsson; Staffan Jacobson; Mikael Olsson; Magnus Jarl; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; friction; wear; metal working; coatings; wire drawing; hot work rolls; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials; tribology; Stålformning och ytteknik;

    Sammanfattning : This thesis focuses on the tribological performance of tool surfaces in two steel working operations, namely wire drawing and hot rolling. In all forming operations dimensions and surface finish of the products are of utmost importance. LÄS MER

  4. 4. The interdependence of plastic behaviour and final properties of steel wire, analysed by the finite element method

    Författare :Henrik Överstam; Magnus Jarl; Sven-Erik Lundberg; Chunhui Luo; Örebro universitet; []
    Nyckelord :Technology; FEM; defects; steel wire; wire drawing; rolling; forging; Teknikvetenskap; TECHNOLOGY; TEKNIKVETENSKAP; Maskinteknik; Mechanical Engineering;

    Sammanfattning : The finite element method (FEM) has been used in order to study the interdependence of plastic behaviour and final properties in steel wire. Three processes metal forming have been studied: billet forging, wire rod rolling, and cold drawing. LÄS MER

    Sammanfattning : The thesis focuses on the organisation today known as the Swedish Federation for Lesbian, Gay, Bisexual and Transgender Rights (RFSL) and its activities from the founding year 1950 to around 1970. RFSL was the first Swedish organisation that worked for non-heterosexual persons. LÄS MER
