The market challenges in the hot rolling of modern flat steel strip grades present an increased demand on rolling mill technologies. Today, the quality and reliability of technological process equipment are often taken for granted by producers. Factors which were of less importance in the past, such as serviceability and consumption figures are becoming more important in this field. Integrated solutions are increasingly in demand. Therefore, Siemens VAI has integrated its process equipment and electrical business for hot-strip mills into SIROLL HM (hot-strip mills) to form a solution package which is highly reliable and maintainable and, when needed, can benefit from Siemens Service Units all over the world. The real challenge in today’s hot rolling of steel strip lies in the automation system of the production plants. Automation is the key to increased through-put, reduced consumption as well as high targets of flatness, profile tolerance and surface quality. Also, the great variety in product mix and flexibility in operation requires a powerful automation system. SIROLL HM also features innovative solutions for the technological process equipment. The solution follows the “Completely Integrated Solution” concept of Siemens VAI. The paper describes the specific technologies for advanced steel grades, superior quality and high productivity.
