Off-Gas Process Control, Water Detection Technologies Ordered by Indiana Steel Producer

A global company providing steel plant and metals industry equipment and services, including heat treating, was recently selected by an Indiana-based steel producer to install and implement its proprietary off-gas process control and water detection technologies.

 Steel Dynamics Inc., at Pittsboro, Indiana, is the second SDI plant to place an order for Tenova’s combined technologies. With this order, SDI Pittsboro will install Tenova’s hybrid extractive/laser NextGen® off-gas analysis system, iEAF® dynamic process control system and Water Detection Technology® (WDT®) as a fully integrated solution on the plant’s 100 ton AC EAF, providing SDI Pittsboro with the world’s most comprehensive technology package of off-gas based EAF process control technology.

Tenova’s technological package combines EAF process automation, thermodynamic models, process hardware, innovative temperature/velocity sensor technology, and water detection.

NextGen® is a hybrid laser/extractive off-gas analysis hardware system that delivers faster analytical response times, requires minimal maintenance and reduces hardware and installation costs.  NextGen® enables the operator to monitor and control furnace conditions helping to mitigate operational risk.

iEAF® Modules 1, 2 and 3 use NextGen off-gas analysis plus Tenova’s proprietary optical off-gas temperature & flow sensors, a link to the plant’s PLC network and a real-time mass & energy balance to dynamically control and optimize chemical energy & electricity consumption  and improve endpoint control to maximize operating cost savings, reduce electrode consumption, increase yield and reduce power on time.  .
