The EAF Quantum is designed to handle scrap steel of varying composition and quality. The electrical energy requirement of the electric arc furnace is extremely low because the scrap is preheated. This reduces both the working costs and the CO₂ emissions.
The EAF Quantum developed by Primetals combines proven elements of shaft furnace technology with an innovative scrap charging process, an efficient preheating system, a new tilting concept for the lower shell, and an optimized tapping system. This achieves very short tap-to-tap times. The electric energy consumption is considerably less than that of a conventional electric arc furnace.
Together with the lower consumption of electrodes and oxygen, this gives an overall advantage in the specific conversion cost of around 20 % . In comparison to conventional electric arc furnaces, total CO₂ emissions can also be reduced by up to 30 % per metric t of crude steel.
Guilin Pinggang is privately owned and located in Pingle near Guilin city in Guangxi Province. The enterprise has an annual production capacity of 1.2 million metric t, and produces rebars, wire and other steel elements for the construction industry. Primetals will supply the complete mechanical and electrical process equipment for the new EAF Quantum electric arc furnace and the twin ladle furnace. The balance of plant equipment and services will be provided by a local design institute.
