Bath Level Measurement System Improves Eaf Melting Process Control

Reliable and accurate furnace bath level data during the melting process is invaluable for good decision making and furnace optimization, while obtaining such information rapidly and safely on a regular basis is of paramount importance. This paper shows how a melting process problem was identified as a concern, how a solution was sought and how a real-time measurement system was tested by simple modification to an existing temperature sampling manipulator. Also how, with furnace power on or off, taking reliable hot heel, fill and running levels could be used to assist melting control, aid decision making and improve safety.
