Ceramic rolling tools for enhanced lifetime and product quality

The main reason for using ceramic materials for metalworking tools is the significantly higher wear resistance compared to commonly used steel tools and therefore the possibility to improve the lifetime as well as the product quality. Ceramic components have been developed for different applications. In this paper the requirements on ceramic components for rolling mills are discussed and the status of our work on the development of the ceramic components and the evaluation of several roll types in field tests are summarized.
