Rasselstein GmbH of Andernach, Germany, recently produced the first tinned coil in its new electrolytic tinning line supplied by SMS Demag.

The new line will boost Rasselstein’s annual tinplate production by around 300,000 tonnes. With the new facility, strip can be meltcoated, chromate-passivated or oiled.

To be able to meet the required tolerances and qualities, Rasselstein will use state-of-the-art instrumentation and control systems. Using a simulation computer, SMS Demag had reproduced the line functions and the dynamic behavior beforehand. Using its "Plug & Work" principle, SMS tested and optimized the complete automation system with its original control cabinets and control desks, which were subsequently to be used on site. In close cooperation with Rasselstein, the operating philosophy of existing equipment was integrated in the operating structure of the new tinning line.

While the Plug & Work test was under way, SMS Demag trained the future operating crew at its test center in the use of the original control desks and control stations.

In addition to new equipment, construction of the line involved existing and modified mechanical equipment.
