Abstract

Energy conservation and the minimization of emissions are the key factors for environmental protection in today’s highly industrialized world. CO2 regulations and the limits imposed on the steel industry for this purpose are already stringent and have a significant impact on the competitiveness of steel producers, particularly those operating their plants in old economies. The pickling and cold-rolling operations that are part of integrated flat-steel production plants are mostly perceived as having a low potential for energy-saving or energy-recovery measures, when compared with those processes in the chain that entail high temperature levels upstream and downstream. But there are still a number of resources within these production units that can provide remarkable contributions to energy savings and also reduce the emission output to zero. Today’s highly productive and high quality linked pickling and cold-rolling facilities (PLTCM) are certainly a classic example of how energysaving measures can be optimized to the limits of the state-of-the-art technology. Many of the measures in place are not immediately obvious: but there are a number of small processes that can provide a substantial contribution to the goal of keeping overall energy consumption and emission output as lean as possible. In addition to measures already in place, there are new and quite promising developments: for example, roll lubrication systems in tandem cold mills have a remarkable potential to further decrease primary energy input and reduce oil consumption. There are other developments in the tandem mill and pickling line to come, with very similar goals. This article provides a brief outline of SIEMENS VAI solutions in the field of pickling and cold rolling that meet the goal of making these processes even more energy-, material-, and emission-saving, and therefore more environment-friendly.
