Tenova Advances Phase II of Acoustic Water Detection in Japan

Collaboration with Topy Industries enhances furnace monitoring and strengthens long-term partnership at Toyohashi Plant Works

Tenova is starting Phase II of its patented Acoustic Water Detection System at Topy Industries Ltd.’s Toyohashi Plant Works in Japan. This project represents the latest step in a long-standing collaboration focused on improving process efficiency, operational safety, and environmental performance in Electric Arc Furnace (EAF) steelmaking.

For nearly two decades, Toyohashi Plant Works has implemented Tenova’s process control and furnace optimization solutions to enhance production and reduce emissions. The Phase I installation of Tenova’s Acoustic Water Detection System - applied to the 200-ton AC EAF shell - marked the first deployment of this technology in Japan.

The system uses advanced acoustic sensors and proprietary data processing models to detect the presence of water in the furnace, providing real-time alarm signals to operators. By analyzing sound and vibration patterns, it transforms operational noise into actionable diagnostic information, improving process reliability and plant safety.

Phase II extends monitoring to the furnace shaft panels, increasing coverage and strengthening the plant’s ability to prevent critical incidents. This integration reflects both companies’ shared commitment to continuous improvement and sustainable steel production.
