In previous years, productivity was the main focus for the steel industry as the market was booming. Situation changed and the market downturn forced the industry to work on the efficiency of the equipment. Furthermore, more countries in the world are implementing new rules and regulations not only concerning energy efficiency and CO2 emissions, but also hazardous off gas emissions. The right approach of SIEMENS VAI Metals Technologies is the EAF QUANTUM. This re-designed and optimized furnace concept stands for minimum conversion costs, maximized output and environmental compliance. Through the utilization of the furnace offgas during the heat cycle, 100% of scrap can be preheated prior to final melting in the furnace vessel. This means considerable energy and cost savings with the substantial reduction in tap-to-tap times (< 33 minutes). In combination with a big hot heel the melting phase is reduced to pure flat bath operation with lowest flicker. With an optimized and patent pending tapping system called FAST, a renewed variant of scrap charging and retaining technology, latest analyzing technologies and a revolutionary design of the offgas-processing system this furnace is the melting aggregate of the future. An energy consumption of 280kWh/t stands for itself.
