Abstract
Operating authorities of cold rolling mills face steadily increasing requirements regarding product quality from their customers: thickness and flatness tolerances are decreasing while surface quality must improve further. In addition, mill flexibility will have to increase to be able to match growing product variety while high mill productivity (throughput and yield) is key to remaining competitive in the global economy. Therefore, to meet such demands a modern automation system is required with advanced technology products and solutions that can be seamlessly integrated into it. To help manufacturers meet their business and technical objectives, ABB has developed and launched the next generation cold rolling mill automation system and performance enhancing technology solutions. One main component from the new technology suite is the advanced thickness control solution. Today’s thickness controls do not fully take into account the decisive interaction between thickness, roll position and tension. ABB has developed a new technology, which considers this fact, and implemented it into a new controller concept. Initial tests at a customer's installation in Germany have shown significant improvements in thickness tolerance reduction as compared with state-of-the-art technology. This new technology is presented in the following and illustrated by examples of on-site measurements.
