Seco/Warwick Engineers Overcome Low Temperature Challenge in Vacuum Furnace for U.S.-Based Global Manufacturer

Seco/Warwick Corp. recently delivered a vacuum furnace to a U.S.-based global industrial manufacturer that has overcome the issue of tight temperature uniformity in a vacuum at low temperatures.

The furnace will operate at 800° F and maintain a +/- 10° F temperature uniformity with 1X10-4 TORR vacuum, in a 12” wide by 6” high by 12” long hot zone. At low temperatures and without an atmosphere, temperature uniformity is difficult because of the lack of convection. The furnace has an operating range of up to 2400°F. Seco/Warwick officials expect to commission the furnace in the first quarter of 2014.

Seco/Warwick Corp. has also commissioned an advanced new furnace design that provides improved durability for stainless steel heat treating. This vacuum furnace is equipped with a 15-bar gas quenching system and a full HMI data retrieval control package for a manufacturer of stainless steel products in the northeast United States.

The Vacuum Team offers vacuum heat treating furnaces for hardening, tempering, annealing, solution heat treating, brazing, sintering, carburizing, carbonitriding, high vacuum, CVD–graphitizing and degassing.  Seco/Warwick has built some of the largest vacuum furnaces in operation today, using advanced technologies like Universal HPQ™ (High Pressure Quench), PreNit® & FineCarb® LPC vacuum carburizing, fully automated control systems and modeling software. Vacuum furnace configurations are available for vertical, horizontal, and elevator style furnaces. Both cylindrical and rectangular hot zones with metallic or graphite heating elements are available.
