Five electrically heated, standard draw batch ovens will be used by East Carolina Metal Treating, Raleigh, N.C., for stress relieving. The ovens have a maximum operating temperature of 1250°F, says oven maker Wisconsin Oven. Guaranteed temperature uniformity of ±10°F at setpoints of 300, 750 and 1250°F was documented with a nine-point temperature uniformity survey in empty oven chambers under static operating conditions, notes the company.
Features of the ovens include a plate-steel outer shell, reinforced steel-plate oven front, lined inner shell and exterior structural reinforcements as required to provide heavy-duty construction. The ovens also include a digital process controller and a digital high limit controller.
