When fully implemented, the combined technologies will bring a number of operational, safety and environmental benefits including reduced energy consumption, water leak detection, increased productivity and yield and reduced greenhouse gas (GHG) emissions.
Tenova’s technologies are designed to work in tandem to provide a complete process solution that combines leading edge hardware, fundamentally sound process control models, web based automation and the most comprehensive water detection available in the steel industry.
NextGen is a proprietary hybrid multipoint laser/extractive off-gas analysis system that delivers exceptionally fast analytical response times, requires minimal maintenance and reduces hardware and installation costs. A single, multipoint NextGen analyzer will be located in the control pulpit at Faircrest and will provide simultaneous and continuous full spectrum off-gas analysis at both upstream and downstream locations.
iEAF process control software to be installed at Faircrest will dynamically optimize EAF energy consumption, maximize operating cost savings and reduce power-on-time. This complete process control solution uses NextGen off-gas analysis together with proprietary optical off-gas velocity & temperature sensors, a PLC link and a real-time EAF mass & energy balance to dynamically control chemical & electrical energy inputs and to optimize refining & endpoint control practices.
Water detection technology uses NextGen off-gas analysis of both H2 and H2O vapor and proprietary software and is designed to quickly detect and alert Faircrest’s operators when there are abnormally high water levels in the EAF.
TimkenSteel's installation represents the second order for Tenova of this fully integrated solution in North America and it provides TimkenSteel with the most comprehensive technology package of off-gas based EAF process control technology available in the world.
