Abstract

The CISDI-GreenEAF innovatively applies the top-side-chute for charging for improving the cold zone of electric-arc furnace (EAF) requiring preheating scrap. It can greatly reduce the operating power consumption during EAF melting by combined use of fume for preheating scrap. The enclosed charging mode and specially-designed structure contribute to less emission of dust and fume during charging while enhancing the metal yield. Thanks to the extraordinary fume temperature control at scrap preheating procedure and fume quenching technology as developed by CISDI, for restraining the regeneration of dioxin.
