Automated Surface Inspection System Significantly Improves Quality Monitoring on a Steel Production Line

Monday, January 13, 2020

AMETEK Surface Vision recently delivered a state-of-the-art SmartView® detection system to help assess pickling defects for Samuel Nelson Steel, a major steel processing company based in Stoney Creek, Ontario, Canada.

Samuel Nelson SteelSamuel Nelson Steel required a reliable, integrated solution to help illustrate which defects are present on the push-pull pickling line, which is used to process hot band carbon steel.  As the company processes steel coils provided by third-party steel suppliers, it was important to be able to identify incoming defects and their location within each coil. The overall aim was to gain the ability to produce simple, one-page reports for customers summarizing the surface quality for each coil pickled.

Previously, Samuel Nelson Steel monitored quality through visual inspection, depending on its operators to inspect the strip and identify defects. This proved to be both time consuming and only gross defects and issues visible to the human eye were detected. In addition, operators were not able to devote 100% of their time to coil inspection, so defects were naturally missed

One of the key capabilities that Samuel Nelson Steel required was the unique side light technology used in the SmartView® solution. This creates a 3D effect that enhances the defect, helping show depth and helps classification and detection accuracy.
 

Ralph Benincasa, General Manager at Samuel Nelson Steel, said: “The competitor systems just weren’t able to provide the same images. The additional insight provided by the system is really helping us accurately identify defects.”

The SmartView® system has exceeded Samuel Nelson Steel’s expectations, delivering several benefits to the steel production process. Operators are now able to spend more time processing as opposed to having to visually inspect the steel surface, thus improving productivity.

Critically, it has helped reduce customer rejections and non-conformances: Samuel Nelson Steel has had already received positive feedback from customers on the accuracy and detail they have been able to provide about coil quality.
