J.L. Becker, a Gasbarre Furnace Group Company, recently manufactured, shipped, and commissioned a complete IQ furnace line at the East Carolina Metal Treating (ECMT) facility in Raleigh, North Carolina. The system is configured to process 36-inch-wide by 48-inch-long by 36-inch-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.
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 to components on the top of the heating chamber. The temper furnaces are electrically heated and are lined with ceramic fiber insulation. A high convection, bung-mounted squirrel cage achieves 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.
According to Jamie Ramm, president of ECMT, the new line reflects the company’s long tradition of continually improving its ability to provide excellent service to its customers.
