The tool described in this paper will increase the precision and consistency of Pomini roll shop design, guaranteeing the best performances to the customers. The change is in the philosophy behind the design process, the simulation is only the way to apply the new idea to design an integrated system taking into account all the resources related to the performances of the roll shop. Obviously the new method is more complex than the previous one, but the benefits of the simulation, of course, will pay the more complexity. Different configuration could be simulated and thus different scenarios can be compared. By attaching the different analysis to the commercial and technical remarks it will be easier to find the best solution and configuration to the customers. Finally one must not forget that the RSS has a great potential because a lot of studies and researches can be done in order to analyze the variables that impact on the performance of the roll shop. For instance, it should be interesting to investigate on the total number of rolls necessary to guarantee a required service level at the mill, or on the best way of switching the rolls in the mill. The new analysis, considering system variability, could suggest, in the future, innovative solutions to improve the performance of the roll shops in the different running environments. Source

Thanks to integrated design and to continual dedication to R&D, Pomini is now able to offer a complete roll shop specially designed for grinding heavy plate mill rolls, from roll shop layout definition to design and installation of the actual machines. Recent products like combi de-chockers, chock tilters, cleaning and preserving tanks, cleaning cabins and shear blade grinders are all aimed at maximum flexibility to meet customer needs, ensuring high performance while respecting the most recent international safety regulations. Several technological innovations were introduced in these machines. This paper presents the latest projects and product range in Pomini's heavy plate mill applications. Source

Systematic integration of safety integrated control systems into the design of the complete roll shop system has provided benefits to the steel mills. In an integrated program, risks have to be identified and addressed by the manufacturer, from the time the roll shop is being planned and designed to when it is built, shipped to the site, and installed. The Siemens Safety Integrated solution adopted by Pomini implements software redundancy, in which rather than waiting until the product is already in use, the analysis is done before the design is finalized, and options are compared using the same methodology. Commercial digital systems are now available with built-in, off-the-shelf solutions that address the needs of machine control. For the risk analysis of the control logic design itself, outside engineering groups are a key part of the design validation. Source

Pomini has designed a roll lifter with integral rotation of the roll chocks to adjust the orientation for positioning the roll on the grinding machine. The new roll lifter reduces the number of roll movements required compared with grinder mounted chock rotators or floor mounted rotation stations. The design of the automatic loader is complicated by the introduction of the rotating devices that implies the addition of moving parts to the lifting machine and, more critically, the need to control the center of mass of the total system, lifter and roll assembly. The loader has a semi-gantry configuration bridge on which a trolley, supporting the tong, can move to perform movements in three perpendicular directions including displacement of the bridge, trolley, and tong that maximizes the working area covered by the machine. The two girders are fixed by means of flanges to a top header beam, and are also connected to each other on the opposite side, by a dedicated beam. Source
