Seven Steps to Energy Efficiency for Foundries

The 7Epsilon approach offers metalcasters a structured methodology for organizational knowledge management and process improvement. Comparing energy consumption with process output Three-phase improvement process Eradicating defects, non-conformities Interdisciplinary knowledge assessments

On an annual casting production of 95 million metric tons, with ferrous alloys costs conservatively set at $1.2 per kg, the total foundry market is well in access of $100 billion. Approximately 15% of these costs are energy costs ($15 billion) and 75-80% of the costs are in the melting process alone. A 10% saving in energy efficiency is equivalent to a saving of $1.5 billion along with substantial reduction in harmful greenhouse gas emissions.
