Abstract
Modern EAF processes are subject to the cost-optimized production of raw steel melt in combination with very flexible productivity. Excellent mixing of the steel melt helps to improve mass and heat transfer, in order to accelerate the melting of scrap and direct reduced iron (DRI), decarburization, homogeneous superheating, alloy distribution, and to avoid skull formation. Direct bottom gas purging not only promotes efficiently mixing of the steel melt in the entire steel bath but also provides constant gas bubble columns to avoid CO boiling retardation. Since few years EAF gas purging systems are experiencing a comeback as state-of-the-art EAF technology world-wide. Recent case studies and new developments on refractory and gas control units are presented. It is shown that gas purging systems represent a safe and modern EAF technology to increase energy efficiency with minimum pay-back period.
Control on the entire gas purging technology from refractory to valve control and purging strategy is crucial for high reliability and availability of the purging system. With years of purging experience, RHI/INTERSTOP presents an entirely revised gas control system for application at the EAF, BOF, ladles etc in secondary metallurgy.
