Abstract

The Roll Defect Management Process (RDMP) is a system which is designed to manage, track and evaluate all mill rolls found in use in the hot and cold production of flat rolled metal strip. The RDMP is capable of detection, distinction and differentiation of various defects found in the mill roll using a nondestructive inspection system for generating variable amplitude output voltage signals corresponding to changes in physical properties found in a mill roll and defines corrective action for each roll type, mill, stand and position. The disposition and corrective actions of the RDMP are automated and dependent on the determination of various thresholds identified by roll, mill and stand.
