Solar Atmospheres Inc. installed a 74-inch-diameter x 72-inch-deep horizontal internal-quench vacuum furnace at its Souderton, Pa., facility. The furnace, which was built by Solar Manufacturing, is designed to quench with argon at 10 bar while utilizing a 600-hp motor running at 460 volts from a variable-speed drive and rear head moveable gas baffle doors. The goal of the system is to be able to quench larger batches of power-generation castings by increasing the cooling rate, eliminating the supplemental use of helium and operating in 100% argon.

The furnace incorporates Solar Manufacturing’s SolarVac 5000 control system, which allows for complete process automation.
