UK-based plantmaker Primetals Technologies has announced that it will supply two new EAF Quantum electric arc furnaces for Chinese steelmaker Henan Yaxin Steel Group Co., Ltd (Henan Yaxin). Commissioning of both new furnaces is scheduled for the first quarter of 2019.
Primetals Technologies stated that the new production plant into which Henan Yaxin is to integrate these arc furnaces will expedite a transition of the existing induction furnace production and converter steelmaking to a more environmentally-compatible electro-steel process.
Developed by Primetals Technologies, the EAF Quantum combines proven elements of shaft furnace technology with an innovative scrap feeding process, an efficient preheating system, a new tipping concept for the lower shell, and an optimized tap system to attain significantly reduced tap-to-tap times. The electrical energy requirement is considerably less than that of a conventional electric arc furnace. In conjunction with reduced consumption of electrodes and oxygen, a cumulative benefit of around 20 percent is achieved for respective conversion costs. Overall, reductions of up to 30 percent of CO2 emissions per metric ton of crude steel can be attained when compared to conventional arc furnaces.
