(EECR-78)Approaching the minimum of energy input – selected activities of ThyssenKrupp Steel Europe for decreasing the specific energy consumption in integrated metallurgical plants

摘要

Coming from the breakdown of energy use inGermany and ThyssenKrupp Steel Europe AG theplant configuration is shown. New production plantsare shortly presented, followed by new technologiesfor further improving the energy efficiency in hot stripmills and subsequent treatment plants. In integratedsteel mills all changes in plants and production haveinfluence on the energy management and newchallenges can appear. The targets for the energymanagement are, to use by-product gasescompletely and at the same time to minimizeadditional costs for power and natural gas. Lots ofsingle steps have to be done already in the past inorder to improve the energy efficiency at existingplants. In view of new challenges to increasingenergy costs and CO_2-emission-trading system inEurope the process has been intensified two yearsago. Smaller steps can be done by the staff, butbigger steps require further investments. By thismethods up to 40 Mio a in sum will be savedsustainably and the process is still going on.
