Mejora de la eficiencia energética de instalaciones siderúrgicas mediante el desarrollo de un sistema integrado de información energética

Abstract

The reduction of energy consumption is today of extremely large interest for the steel production. To identify possibilities of energy efficiency improvement, the availability of suitable energy consumption data is essential. Usually, these data are only available as time series without relation to products or process conditions. This work presents progress made for the improvement of the energy balance of the factory by means of the development of an integrated energy information system that offers unprecedented prospects for the analysis of energy consumption in the steel manufacturing process. In order to achieve this ambitious goal, it has been created an energy information database at which the energy consumption is directly assigned to the different intermediate or final products, and to connect it with the production conditions, which are stored in the quality and process databases. Based on this information, automatic procedures for different evaluation purposes have been implemented taking into account both environmental and technical aspects.
