Electromagnetic stirring in electric arc furnace

Electromagnetic stirring in electric arc furnace (EAF EMS) was the first application for low-frequency electromagnetic stirring in the metal industry. Meanwhile, EAF technology has developed rapidly and this article will discuss the present state-of-the-art electromagnetic stirring systems. More importantly, the paper will present the impact of EMS on the EAF process and the potential for improvements in productivity and operating cost which can be predicted. Improvements to EAF operations from EAF EMS in the following aspects of the process will be discussed: scrap melting, homogenization, steel deoxidation, slag reduction, decarburization and tapping.
