In 2005, an ambitious program was started to reduce casting furnace energy consumption in Rio Tinto Alcan (RTA) casthouses. In 2008, a major reduction step was reached by implementing this energy efficiency program in all plants, focusing on the energy efficiency of each casthouse in terms of consumption (m3 of gas) and specific energy consumption (MJ/t of cast metal).
To further reduce energy consumption, a new strategy was recently developed and is described in this paper. The main tool of this strategy is a standardized energy efficiency indicator. This indicator takes into account not only intrinsic furnace operating parameters such as burner efficiency and pressure control but also some specific production characteristics (casthouse layout, hot liquid temperature, mass of scrap metal, and alloy ingredients). It allows comparing adequately energy efficiency between casthouses and identifying best practices and improvement potentials. Some industrial applications of this tool are also presented.
