McInnes Rolled Rings, which recently completed an $8 million expansion to its manufacturing facility, has announced that there are now ABS certified. The recent addition expanded 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, the newly built state-of-the-art bay expanded the daily tonnage capacity.
McInnes used Can-Eng Furnaces Intl. Ltd. to design and install the most advanced technology to process large diameter product. The furnace & quench tank designs were augmented by a customized material handling system by Dango & Dienthal Hollerbach GmbH capable of processing loads up to 25 tons. The systemÂ’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.
