In electric arc furnace (EAF) steelmaking, reduction in electricity consumption and Increased productivity can be realized by preheating the scrap up to 700°C by sensible heat in offgas. The environmental preheating and continuous charging (EPC) system combines the advantages of 100% scrap preheating and continuous scrap feeding through its chambers, without opening the EAF roof. This paper compares the EPC to the existing systems.
