Solar Atmospheres of Western Pennsylvania and Solar Manufacturing, Inc. have announced that construction of the world’s largest vacuum furnace is nearing completion. The multi-million dollar project is expected to be completed in June with the commissioning of the furnace into production in July of 2016. This unique piece of equipment will not only open up new production opportunities within the North American vacuum heat treating markets, but also internationally.
The working hot zone of this high vacuum (three 89 cm / 35″ Varian diffusion pumps) furnace is 2 m / 80″ diameter X 14.6 m / 48′ long with a maximum operating temperature of 1316°C / 2400°F. Thirty five points of temperature will be surveyed to within +/- 10°F per the stringent AMS 2750E specification. The robust US Patented dual load car design will have the capacity to transfer up to 68,039 Kg / 150,000 pounds of material in and out of the furnace.
For dimensionally critical, near net shaped jobs, the dual load car design will also have the capability to maintain the critical support needed at elevated temperatures to keep parts flat to within 0.762 mm / 0.030″.
