Abstract

High performance rolls and rings help to increase mill performance and efficiency. In the finishing stands, many mills already use high tech materials, such as carbide rings. Whereas in the roughing and intermediate stands, standard monocast nodular iron rolls, with moderate performance are still used. Spin casting technology offers a huge potential for improvement of roll life in the roughing and intermediate stands, increasing mill efficiency. New roll materials, containing high hardness carbides, have been developed and are now utilized in various applications, including slitting.
