According to Tenova, which supplied the system, the system detects and alerts plant operators to abnormal water conditions in the furnace. The equipment is the latest of improvements to the furnace. 

Last year, the mill commissioned Tenova’s NextGen hybrid optical and extractive offgas analysis hardware and its iEAF process control models. Tenova said the upgrades have reduced consumption of electricity and process inputs, such as oxygen and natural gas. 

"Complete system performance has more than doubled from the original estimated savings target determined at the start of the project, with total electrical and chemical energy costs per ton of steel being reduced by over 6%," Tenova said.
