Nucor Steel Seattle Inc. placed an order for the installation and commissioning of one complete iEAF system with Tenova Goodfellow Inc. The system includes NextGen hybrid optical/extractive off-gas analysis hardware, iEAF process-control models, proprietary off-gas velocity and temperature optical sensors, as well as a water-detection system. The iEAF technology is designed to reduce operating costs, energy consumption and improve endpoint detection by providing dynamic control of both electrical and chemical energy inputs. It uses full-spectrum off-gas analysis provided by the NextGen system together with off-gas velocity and temperature inputs received from the plant’s PLC network to close a fundamental mass and energy balance for the EAF in real time.
