L&L Special Furnace Co. shipped a front-loading box furnace to an aerospace manufacturer located in the southeastern United States. The state-of-the-art-facility will be opening soon, and it will be a central part of a heat-treating center for aerospace and military components. The highly uniform furnace has working dimensions of 60 inches wide x 60 inches high x 60 inches deep. There are a series of castable piers and an alloy grid that supply a very stable work platform for various part sizes and configurations.
A 500°F (260°C) top-loading, electrically heated oven is used for heat treating parts. Workspace dimensions measure 96 inches wide x 20 inches deep x 20 inches high.
A vacuum transducer has been developed that combines capacitance diaphragm sensor technology with piezo diaphragm and wide-range MEMS Pirani heat-loss sensor technology.
Editor’s note: The following is an edited (for length) transcription of an interview between SECO/WARWICK’s Tom Hart and Dan Herring, The Heat Treat Doctor. It was part of the company’s E-Seminar held in September 2020.
Bodycote announced the opening of a new heat-treatment facility in Elgin, Ill. The facility is now fully operational and supporting customer requirements. It continues to provide all of the processes and capabilities that were previously offered at Bodycote’s Melrose Park location. In addition, the Elgin facility offers nitriding, Corr-I-Dur, nitrocarburizing and low-pressure carburizing (LPC) to customers from the agricultural, mining, construction, automotive and other manufacturing supply chains in the upper Midwest region.
It all began with a single furnace in New Jersey. William R. Braddock started Braddock Metallurgical with that lone salt pot furnace back in 1953 offering heat-treat services for local machine shops.
Can-Eng Furnaces International Ltd. has been contracted to deliver a number of different furnace types to multiple customers in the United States and Canada for the heating and heat treatment of aluminum and steel closed-die forgings. The furnace configurations either under construction in the company shops or in the early stages of commissioning include rotary hearth, chain conveyor, roller hearth, mesh belt and cast-link belt. These furnaces will be delivered to Georgia, North Carolina and Ontario. They will be used in the production of powertrain, suspension and steering/linkage components for the automotive sector.
