Advanced Atmosphere-Control System for Annealing

Linde LLC, Bridgewater, NJ, has introduced its Hydroflex atmosphere-control system, a universal solution for clean and bright oxide-free annealing of steel, stainless steel, copper, bronze or brass. Applications include automotive, aerospace and military components, construction and industrial equipment, and electrical systems.

“The Hydroflex system can use one or more carrier gases—nitrogen or argon—to maintain the furnace pressure while a controlled ratio of hydrogen helps prevent oxidation,” explains Linde’s Akin Malas. With the Hydroflex technology, many annealing tasks can be completed with nonflammable gas mixtures containing less than 5 percent H2. This contributes to fire safety while optimizing the use of H2 in the process.

“Uses go beyond annealing,” adds Linde’s Grzegorz Moroz. “The control system can help optimize process efficiency and enhance productivity of sintering and brazing operations as well.”
