Broken roll detection, application, algorithm and its basic principles of sensing

Description

This paper will describe the distributed industrial inline application "broken roll detection", which is placed in a really harsh industrial environment, with all aspects from the sensing base to algorithm, implementation and technology. In a seamless steel tube production the pipe shells produced in the punch bench are running through many roller stands (3-roll system) to get the final dimension. If one of the rolls is broken, structural voids near the surface are the consequence. So finding the structure voids on the tube means to find broken rolls. Since pipe shells are hot (approximately 900°C) after passing the rolls, temperature distribution on its surface is different when voids happen.
