Today the installation of fully continuous rolling mills or mills coupled to pickling lines take clearly the precedence over the installation of coil to coil tandem cold mills. For a wide range of high-quality cold mill product applications continuous operation is the key to consistently reach the actual demands for quality related features due to strongly stabilized process conditions at high overall process efficiency. Continuous operating cold mills provide the capability for yield optimization and the basic environment to save operational cost. Making the operation continuous itself is often not sufficient to take full advantage of the inherent process potentials. Almost always supporting measures in the existing equipment and automation systems have to be implemented to take full advantage of the investment. SIROLL CM (Siemens cold rolling technology), the fully integrated Siemens cold mill system provides beside complete line solutions, thanks to its modular structure also a number of single solutions and mechatronic packages, which can be used very effectively for almost any upgrade needs. The consequent plug and play philosophy as well as the fit to purpose flexibility of its components makes it easy, cost effective and time saving to meet the upgrade objectives. This paper describes the numerous available upgrade packages from single machines to integrated packages inside SIROLL CM which can be used to target specific quality improvement, yield maximization as well as operation and maintenance simplifications measures at various positions inside a cold mill. The identification of useful upgrade measures is not always that obvious, even after long time of operation. SIROLL CM includes pure engineering packages starting with operation, function and quality studies at a mill to identify bottlenecks, shortfalls and improvement potentials. The paper will include suitable measures e.g. capacity studies, de-bottlenecking investigations or other process optimization steps.
