Largest Commercial Vacuum Furnace Nearing Completion

/ FEATURED NEWS, HEAT TREAT NEWS INDUSTRIES, HEAT TREATING EQUIPMENT, VACUUM FURNACES

Solar Atmospheres of Western Pennsylvania and Solar Manufacturing, Inc. have been very busy these days building the largest vacuum furnace anywhere in the world.  The working hot zone of this high vacuum (three 35 inch Varian diffusion pumps) furnace is 80 inch diameter X 48 feet long with a maximum operating temperature of 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 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 .030 inches.

All of the major components have been delivered and installed.  The gas and water systems are in place.  The remaining installation of all the electrical components and wiring will occur over the next several weeks.  This 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.

Heat Treat Expansion Complete at McGinnis Rolled Rings

/ ENERGY HEAT TREAT, FORGING, HEAT TREATING EQUIPMENT, PROCESSES
 McInnes Rolled Rings has completed an $8 million, 25,000-square-foot expansion to its current manufacturing facility.  The addition expands its present heat treat size capabilities by providing the ability to quench and temper forgings up to 144 inches in diameter. With separate high agitation water and polymer quench tanks, this new state-of-the-art bay will significantly expand the daily tonnage capacity to ensure the fastest delivery times available in the industry.

McInnes contracted with Can-Eng Furnaces Intl. Ltd. to design and install the most advanced technology to process large diameter product. The furnace & quench tank designs are augmented by a customized material handling system by Dango & Dienthal Hollerbach GmbH capable of processing loads up to 25 tons.  The system’s fast transfer from furnace to quench tank provides optimal and repeatable process controls.

“This new bay nearly doubles our quenched and tempered offerings to the power transmission industry and adds the ability to solution anneal large diameter stainless steel rings. Also, the addition of water quenching improves our ability to meet the high property demands of the custom flange markets,” said Shawn O’Brien, VP Sales & Marketing.

The expanded heat treat operation will officially begin service on March 1, 2016.
