Abstract

A new furnace concept with scrap preheating was developed in conjunction with flat bath operation, known under the trademark name. Simetal EAF Quantum™. It enables scrap melting with a specific energy consumption of only 280 kWh per ton of scrap. This new furnace stands for minimum conversion costs, maximized output and environmental compliance. 100% of the charged scrap is preheated through the utilization of the furnace offgas during the heat cycle. This leads to energy and cost savings with a reduction of the tap-to-tap time to 33 minutes. Pure flat bath operation with lowest flicker is the result of an adequate hot heel and a new tapping system. With this patent pending tapping system, a renewed variant of scrap charging and retaining technology as well as a revolutionary design of the offgas-processing system, this furnace is the melting aggregate of the future. An energy consumption of 280 kWh/t in combination with reduced consumptions of oxygen and fuel stands for itself.
