Mesh belts come in all shapes, sizes, materials and weaves and are used for such diverse applications as case hardening, brazing, sintering and glass-to-metal sealing to name a few. Belts run at temperatures from near ambient to several thousand degrees. They are expected not only to work in the furnaces but also for external part conveyance or in water, oil, brine, polymer and salt quench tanks. Mesh belts are exposed to a multitude of furnace atmospheres ranging from air to pure hydrogen and can be exposed to oxidation, sulfidation, carburization and nitriding. They operate in environments spanning dew points from below -100°F to above +100°F. And most of us expect our belts to perform well beyond normal expectations. How do they survive, and how can we make them last even longer? Let’s learn more.
The January 2017 issue of Industrial Heating features our cover story on a horizontal quench system, the importance of materials science in failure analysis, a new quarterly column, Academic Pulse, and much more.
