Electric Arc Furnace Camera System Improves Safety and Furnace Turnaround Times for Steel Manufacturers

Press release date: Oct 01, 2012

Trevose, PA – Lenox Instrument Company’s Electric Arc Furnace Camera System has been developed specifically for high-resolution imaging inside an Electric Arc Furnace (EAF).

An Electric Arc Furnace (EAF) is used in steelmaking to heat charged material, usually scrap metal, by means of an electric arc generating furnace temperatures that can reach 3200°F (1760°C).

An EAF consists of a water-cooled refractory lined vessel covered with a retractable lid, through which one or more graphite electrodes enter the furnace to create an arc between the charged material and the electrode(s) generating the heat required to melt the material.

Once proper temperature and chemistry is attained the liquid steel is “tapped” by tilting the furnace and allowing the molten steel to pass through a hole, referred to as a taphole, that passes vertically through the narrow off-center section of the furnace into another vessel for transport to the next operation. After completion of the tapping process the taphole is refilled with a refractory plugging composition, usually sand.

The Lenox Electric Arc Furnace Camera can be installed through a small opening in the furnace wall, above the taphole, allowing the operator to view slag, the tapping process, inspect the condition of the refractory, taphole and spout, and monitor the refilling of the taphole.

The EAF Furnace Camera, available in 24 inch (61 cm), 31 inch (79 cm), and 36 inch (92 cm) lengths, eliminates the need for manual observation with improved safety and furnace turnaround times.   Electric Furnace Camera Systems can also be used to monitor ladle furnaces, transfer ladles, blast furnaces and torpedo cars.

Each Lenox Electric Arc Furnace Camera System is designed, manufactured in the U.S.A. and serviced in-house by Lenox Instrument, and is backed by an industry-leading two-year warranty.
