Gasbarre Furnace Group/J.L. Becker shipped a large-capacity gas-fired temper furnace to a specialty alloy manufacturer located in the northeast U.S. The furnace is designed to temper workloads after hardening. It is capable of processing workloads 32 feet wide x 6 feet long x 4 feet high that weigh up to 40,000 pounds. Temperature uniformity is achieved through five zones of heating, recirculation fans and a custom-designed baffling system. As a result, the furnace is capable of achieving ±10°F from 800°F to 1400°F.

A vertical-lift door and hearth enables the furnace to be installed in the company’s existing J.L. Becker heat-treating system and loaded and unloaded by a J.L. Becker manipulator. The control system incorporates an Allen Bradley MicroLogix PLC and PanelView HMI. A Eurotherm 3216 instrument controls the temperature in each zone.
