Abstract
Almost all ferrous foundries use press scrap as the main charge material. In this study, we tried to reduce the melting energy by optimizing the shape and size of press scrap. The experiment was conducted using 3t/h medium frequency induction melting furnaces at two foundries. In the case of the improved condition, customized press scrap was used for initial charging, and small press scrap was used for additional charging. The energy reduction effect of the improved condition was enhanced by reinforcing the cleaning process of the return scrap surface. The reduction ratios of the melting energy basic unit by the improved condition at the two foundries were almost the same (23.3 and 23.9%). The improved condition was very effective in both foundries with different basic unit levels. The reasons for energy reduction and the economic effects of the improved condition were described.
