High-temperature inert gas conveyor belt furnace

At the Witten site (FORTIS area), the institute has a conveyor belt furnace of the type HTE 1200-200/80-1500 (Kohnle, Birkenfeld), which can be operated under various process gases (argon, hydrogen, nitrogen). In addition, the metered addition of special gases such as monosilane is possible via an additional gas feed. The heating speed and target temperature of the components in this soldering process are determined by the selected belt speed and the furnace temperatures set in the three heating zones of the annealing area. The furnace is equally suitable for soft, hard and high-temperature brazing processes as well as for general heat treatments, including oxidation-sensitive materials.
