J.L. Becker, a Gasbarre Furnace Group Company, recently manufactured, shipped and commissioned a complete IQ Furnace line at the East Carolina Metal Treating facility in Raleigh, NC. The system is configured to process 36" wide by 48" long by 36" high workloads that weigh up to 4,000 pounds and includes an integral quench furnace, two temper furnaces, a spray and dunk washer, a powered load transfer cart, a scissors lift table and two stationary load tables. According to Jamie Ramm, president of ECMT, the new line reflects the company''s long tradition of continually improving their ability to provide excellent service to their customers.

The IQ Furnace features a high energy efficient recuperative radiant tube heating system, nitrogen/methanol panel and a double deck elevator which enables multi-load processing. To ease maintenance, the circulating fan assembly is bung mounted, and a catwalk provides access components on the top of the heating chamber. The temper furnaces are both electrically heated and are lined with ceramic fiber insulation. A high convection, bung mounted squirrel cage achieves excellent temperature uniformity throughout the workload area in the temper furnaces. The spray and dunk washer is electrically heated. Dunking, oscillating and spraying sequences are employed to remove quench oil, machine lubricants and other contaminants from workloads in the washer. An oil separation system removes contaminants from the wash solution. A powered double-ended cart transfers workloads throughout the system. To meet AMS 2750 requirements, the equipment is configured to tie into ECMT''s existing SCADA system for data logging.
