(EECR-106)Potential for energy saving and environmental protection in a PLTCM and Siemens VAI solutions therefore

摘要

Energy conservation and the minimization of emissions are the key factors for environmental protection in today’shighly industrialized world. CO_2 regulations and the limits imposed on the steel industry for this purpose are alreadystringent and have a significant impact on the competitiveness of steel producers, particularly those operating theirplants in old economies.The pickling and cold-rolling operations that are part of integrated flat-steel production plants are mostly perceivedas having a low potential for energy-saving or energy-recovery measures, when compared with those processes inthe chain that entail high temperature levels upstream and downstream. But there are still a number of resourceswithin these production units that can provide remarkable contributions to energy savings and also reduce theemission output to zero. Today’s highly productive and high quality linked pickling and cold-rolling facilities(PLTCM) are certainly a classic example of how energy-saving measures can be optimized to the limits of thestate-of-the-art technology. Many of the measures in place are not immediately obvious: but there are a number ofsmall processes that can provide a substantial contribution to the goal of keeping overall energy consumption andemission output as lean as possible.In addition to measures already in place, there are new and quite promising developments: for example, rolllubrication systems in tandem cold mills have a remarkable potential to further decrease primary energy input andreduce oil consumption. There are other developments in the tandem mill and pickling line to come, with verysimilar goals. This article provides a brief outline of SIEMENS VAI solutions in the field of pickling and cold rollingthat meet the goal of making these processes even more energy-, material-, and emission-saving, and thereforemore environment-friendly.
