Tenova Wins Order for Upgrades to Nucor EAF
11/12/2015 - Tenova Goodfellow Inc. has won an order for one of its iEAF control and analysis systems at Nucor Steel Seattle Inc.
In a statement, Tenova Goodfellow said the Nucor Corp. mini-mill is installing the system to reduce operating costs and energy consumption and to improve endpoint detection.
The system includes Tenova’s NextGen hybrid optical/extractive offgas analysis hardware, iEAF process control models, proprietary offgas velocity and temperature optical sensors as well as a water detection system.
The system allows for dynamic, second-by-second control of both electrical and chemical energy inputs in an electric arc furnace. It runs on information received through the system’s NextGen offgas analysis system and offgas velocity and temperature and inputs received from the plant’s programmable logic controller.
Tenova said the NextGen system can boast of faster analytical response time, lower maintenance requirements, and less hardware and installation costs. It also has comprehensive water-leak detection capabilities based on both H2O vapor and H2 analysis.
Tenova said the Seattle mill, which has one EAF and makes angles, channels, flats, rounds and rebar, will be Nucor’s reference site for its NextGen and iEAF technologies.
