20 YEARS OF EXPERIENCE WITH SCRAP PREHEATING TECHNOLOGY

Abstract

More and more countries worldwide implement new rules and regulations to improve energy efficiency and cut CO2 and hazardous off-gas emissions. Thus electric steelmakers need technology that keeps costs low, increases productivity and helps them adhere to environmental regulations. Decades of knowledge in preheating technology, and several different innovative applications which had been solution for many unique cases have been brought together and announced in 2010. EAF Quantum was designed as a pragmatic solution that meets requirements for high energy and cost efficiency, increased productivity and lowest emissions. Whether scrap, partly hot metal or direct-reduced iron (DRI) is charged, EAF Quantum is the solution for highly productive electric steelmaking at extra low conversion costs.
