About Hot rolled bar and rod

  • Quality control: Detection of defective areas in test material and assignment of test piece to a quality category 
  • Process control: Identification of defective rolling elements in the line that cause periodic defects
  • Coil holder: Water-cooled and robust stainless steel construction for raw industrial environment, shown in photo
  • Networking: Integration of inspection system into existing computer networks and line control systems
  • Rod/bar characteristics: All metals; Ø 4-115 mm (0.16-4.5 in)
  • Temperature: Max. 1200 °C (2192 °F)
  • Production speed: Max. 200 m/s (656 ft/s)
Manufacturers of hot rolled bar and rod struggle not only with randomly distributed flaws in the finished products but also with defective rollers that lead to repetitive defects. Our hot rod inspection system addresses both of these concerns. Firstly, the quality of the rod or bar is evaluated and classified for you using a classification scheme that you can configure. Secondly, you can pinpoint damaged roller elements in the production line that cause periodic defects, provided you have the necessary roller data. The EDDYTREND  software displays the last 4 coils to let you identify quality trends early and stop production deterioration before it escalates.
