- Abstract
In the steelmaking industry, the demand and expectations from the customers are more stringent than ever, primarily owing to increased competition and stressed margins. Any steel coil with holes on the surface passed to the customer can potentially result in a severe complaint and a dent in the company's reputation of being a quality product supplier. In the cold-rolling mills (CRM), supplier companies roll premium-grade steel strip products for several industry sectors including automobile customers. Manual and other pre-existing detection techniques of smaller miniature size holes on the strip moving with the high line speed is highly unreliable. Passing an undetected hole to the customer has serious consequences as it may cause damage to the costly equipment like die and can result in rejection of a complete BIW (body in white). To overcome this challenge, we propose an image processing-based miniature size hole detection system, which helps CRM (cold-rolling mill) to detect the material with pinholes in-process and prevents them from reaching the customers. Equipped with an innovative imaging setup including blue light and viewing angle enhancements, our proposed system surpasses the pre-existing hole detection technologies by a huge margin. This system has been developed and tested in a customer-facing line.
