AN INTRODUCTION TO ENERGY MANAGEMENT

2021-4-25  The iron and steel industry is the second-largest consumer of energy among all industrial sectors, with energy costs representing around 2025% of the total input - costs for iron and steel producers. Lowering these costs has therefore become one of the most important priorities for steel producers (Horvath, 2012).
