Abstract

For any kind of rolling process, the efficiency, productivity and overall rolling quality is directly dependent on the geometry and surface quality of rolls as well as the 3D- geometry of the mill window. Due to the complexity of the relevant mill components a structured and systematic auditing and 3D-survey of the components is the base. The holistic overview and decision making is only possible through a structured handling of all relevant information. The presented approach generates detailed knowledge about all relevant mill components as well as a detailed understanding of all relevant mill processes and the organizational structure. The presented techno- commercial mill transformation offers the significant optimization of total cost of ownership of any type of rolling mill, the clear increase of mill uptime, reliability, flexibility and consistent product quality. The target is to better align with any kind of market requirement. All collected information and data are available through an overall mill management, maintenance and operation system allowing the systematic performance and lifetime analysis for any relevant mill component. Based on reliable equipment, a far reaching mill management system and the focused organizational transformation it is possible to change from ''learning by doing'' to ''doing what was learned”.
