Solar Manufacturing recently shipped five Mentor vacuum furnaces to a company in the southeast United States that provides products to industries including aerospace and medical. The furnaces include a graphite-insulated hot zone, a load weight capacity of up to 250 pounds and a maximum operating temperature of 2400°F (1315°C). They will be used primarily to sinter and stress relieve stainless steel components.

Wisconsin Oven shipped a continuous-duty conveyor oven to a U.S. manufacturer that will use it for stress relieving steel snap rings used in automotive parts. The natural-gas-fired oven has a maximum operating temperature of 650°F and a work zone measuring 2 feet, 2 inches wide x 10 feet long x 1 foot high. When preheated, the oven has sufficient capability to heat 350 pounds of steel parts per hour from 70°F to 550°F. Heated air will be delivered in a horizontal airflow configuration through a fully adjustable boxed duct located along the length and across the height of the work chamber.

Gasbarre Thermal Processing Systems built and commissioned a high-temperature car-bottom furnace for a manufacturer of excavating equipment based in the southern U.S. The furnace has a work zone of 84 inches wide x 144 inches long x 48 inches high with a 16,000-pound load capacity and an operating temperature range of 1000-2282°F (538-1250°C). It will be used for stress relieving, normalizing and other high-temperature processes. The furnace, which replaced an existing furnace, gives the manufacturer improved operating efficiency and higher-temperature processing capabilities.

SECO/VACUUM (SVT), a SECO/WARWICK company, sold a vacuum tempering furnace to a global manufacturer of cutting tools. The furnace, which will be used for tempering and stress relieving metal parts, is part of the company’s expansion and complements another vacuum tempering furnace commissioned earlier in 2019 at the facility. The horizontal, front-loading furnace has an all-metal hot zone for clean vacuum processing. It includes a convection fan and a pressurized gas quench for quick cooling.

Wisconsin Oven Corp. shipped five electrically heated, standard draw batch (SDB) ovens to East Carolina Metal Treating in Raleigh, N.C. The ovens, which have a maximum operating temperature of 1250°F, will be used for stress relieving. The basket dimensions of each oven are 2 feet wide x 3 feet long x 2 feet high. Guaranteed temperature uniformity of ±10°F at setpoints 300°F, 750°F and 1250°F was documented with a nine-point temperature uniformity survey in empty oven chambers under static operating conditions.

Wisconsin Oven Corp. shipped a stress-relieving oven to a company in the technology industry. The natural-gas-fired oven will be used for stress relieving fabricated steel tanks. With a maximum operating temperature of 1250°F and work-chamber dimensions of 10 feet, 1 inch wide x 7 feet, 6 inches long x 6 feet, 8 inches high, the batch unit has the capacity to heat 6,060 pounds of steel from 70° to 1130°F in approximately 120 minutes.

In multiple-burner installations on industrial ovens and furnaces, pulse-firing techniques can improve temperature uniformity, reduce emissions and cut overall fuel costs. Is it right for your process?

SECO/VACUUM, a SECO/WARWICK company, received an order from a global manufacturer to supply a second vacuum furnace to its U.S.-based operations. This second furnace, a vacuum temper furnace for tempering and stress relieving metal parts, is part of the company’s U.S. expansion and becomes a centerpiece in a new processing line. The horizontal, front-loading furnace has an all-metal hot zone for clean vacuum processing.

Whether homogenizing aircraft aluminum after casting or solution heat treating wrought and cast automotive and aircraft components, end users demand the best in heat-treat furnace performance.
