Low conversion costs, high productivity, greater environmental compatibility: Siemens develops new electric arc furnace for efficient electric steel production
The Simetal EAF Quantum electric arc furnace from Siemens combines tried-and-tested elements of preheating furnace technology with a number of new developments. These include a new scrap charging process, an efficient preheating system, a new tilting concept for the lower shell, and an optimized tapping system. A reference furnace with a tapping weight of 100 tons achieves an output of 1.35 million tons of crude steel per year with a tap-to-tap time of 33 minutes. The electrical energy consumption, at just 280 kilowatt-hours per ton, is considerably lower than that of a conventional electric arc furnace. Coupled with a lower consumption of electrodes and oxygen, this results in a total specific conversion cost advantage of around 20 percent.
