SMS group has developed a bunch of new technological solutions, ensuring an even more flexible and economically and ecologically efficient plant. By using the newly developed features, it is possibly to design new plants in a much more high-performance way. An example is the high-performance cold tandem mill, equipped with smaller work rolls resulting in lower investment and operating costs. Further innovative mill features like the newly designed Siemens-HT drive spindle and redesigned mill auxiliaries help to cut investment and operation costs. SMS group supports these requirements by permanently advancing its proven X-Roll rolling technology. The new generation of X-Roll cold rolling mills presents numerous plant technological advancements and innovations, available in new equipment as well as for modernizations. The example presented in this paper is the new high-performance tandem mill with 4-high CVC plus mill stands. In order to fulfil market requirements for increasing portions of high-strength materials with smaller final gauges, the high-performance TCM in CVC plus 4-high design features work roll diameters below 400 mm with consequently low rolling force requirements and reduced investment costs. This new mill configuration will be completed by features like Siemens-HT spindle for work roll drive, ECU (Emulsion Compact Unit) and other redesigned mill auxiliaries to ensure an economical and ecological cold rolling process.
