1. 1. Have you heard about wire? Monitoring of the wire drawing process

   Författare :Joakim Larsson; Christer Korin; Anton Jansson; Patrik Karlsson; Rachel Pettersson; Diana Janis; Örebro universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wire drawing; process monitoring; condition monitoring; drawing force; performance monitoring;

   Sammanfattning : Wire made from metal is a fundamental component found in almost every complex product, ranging from a simple pen to a spacecraft. It is used to manufacture nails, screws, springs, rivets, cables, welding electrodes, and numerous other items that surround us daily. LÄS MER

3. 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

4. 3. 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

5. 4. Tribology in Metal Working

   Författare :Maria Nilsson; Staffan Jacobson; Mikael Olsson; Magnus Jarl; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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; Steel Forming and Surface Engineering;

   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

7. 5. Through air drying : Thermographic studies of drying rates, drying non-uniformity and infrared assisted drying

   Författare :Aron Tysén; Lars Nilsson; Shri Ramaswamy; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Through air drying; TAD; Drying; Dewatering; Water removal; Infrared drying; Non-uniformity; Variability; Formation; Thermography; Tissue; Fabric; Wire; Pulp; Grammage; Chemical Engineering; Kemiteknik;

   Sammanfattning : The removal of water is an integral part of papermaking. The drying process is responsible for a great share of the energy used in the paper machine. Premium grade tissue products are dried by through air drying. Large volumes of natural gas are burned to heat the air drawn through the paper web to achieve the drying. LÄS MER
