Energy Analysis of EAF With Electromagnetic Stirring

摘要

In this study, electromagnetic stirring (EMS) for electric arc furnace (EAF) application is investigated. The objective is to analyze EAF operations with and without EMS in order to provide necessary information to understand the benefits of EMS. Static material balance and energy balance models are built up including major chemical reactions. Impact of melt bath stirring on scrap melting is analyzed. Major conclusions of the energy analysis are that EMS has significant impact on scrap melting, especially for large pieces of scrap; shorter melting time is expected with improved temperature and chemical composition homogenization; in addition, EMS has significant environmental impact.
