Press article on the success Charter Steel, Wisconsin, USA has had with the hot rod testing system.

	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")
	Temp.: Max. 1200°C (2192°F)
	Production speed: max. 200 m/s (656ft/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, the system pinpoints damaged roller elements in the production line that cause periodic defects. It also displays the quality classification of the last 20 coils to let you identify quality trends early and stop production deterioration before it escalates.
