The system uses advanced acoustic sensors and proprietary data processing models to detect the presence of water in the furnace. This provides real-time alarm signals to the operators, Tenova said.

Analysis of the sound and vibration patterns transforms operational noise into diagnostic information, improving process reliability and plant safety. 

While Phase I focused on installation of Tenova’s Acoustic Water Detection System, Phase II extends monitoring to the furnace shaft panels. Tenova said this increases coverage and strengthens the plant’s ability to prevent critical incidents. 

“Our partnership with Toyohashi Plant Works is a testament to the power of long-term collaboration and shared vision. We are proud to support their journey toward more efficient and sustainable steelmaking, and we remain committed to delivering technologies that drive real-world results,” said Marcello Pozzi, chief executive officer of Tenova Goodfellow Inc. 

The companies said the project is focused on improving process efficiency, operational safety and environmental performance in electric arc furnace (EAF) steelmaking. Working together for almost two decades, Toyohashi Plant Works has used Tenova’s process control and furnace optimization solutions to enhance production and reduce emissions.
