A spring manufacturer received a shipment of two industrial conveyor ovens that will be used to stress-relieve torsion springs. The custom ovens, designed and shipped by Lewco Inc., are rated for a maximum temperature of 650°F (343°C).

Unplanned downtime is one of the biggest challenges and greatest expenses for processors. Principal reasons for unplanned downtime include unexpected equipment maintenance and failure. 

Can-Eng Furnaces International Ltd. was contracted to engineer and commission two large-capacity heat-treatment furnaces for a global producer of highly engineered metal earth-moving, construction and mining equipment.

Can-Eng Furnaces International Ltd. was contracted to engineer and commission two large-capacity heat-treatment furnaces for a global producer of highly engineered metal earth-moving, construction and mining equipment. As part of this turnkey contract, Can-Eng designed and commissioned individual tempering and stress-relieving furnaces.

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 (343°C). When preheated, the oven has sufficient capability to heat 350 lb 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.

A manufacturer of excavating equipment based in the southern United States will use a high temperature car-bottom furnace for stress relieving and normalizing. The furnace, which was built and commissioned by Gasbarre Thermal Processing Systems, has a 16,000-pound load capacity and an operating temperature range of 1000 to 2282°F (538 to 1250°C). 

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.
