Equipment Overview
The Continuous Hydrogen Annealing Furnace, also known as the Hydrogen Atmosphere Pusher Furnace, uses a pusher mechanism to continuously convey materials through the furnace chamber under a pure hydrogen or hydrogen-nitrogen protective atmosphere. It is widely used for degreasing, sintering, annealing, and reduction processes in powder metallurgy, cemented carbide, magnetic materials, tungsten/molybdenum products, and electronic ceramics.
Working Principle
Material enters through a sealed loading chamber, where air is purged and replaced with a hydrogen atmosphere. A pusher mechanism then advances the material step by step through multiple heating zones, where it is heated, held, and cooled according to a preset temperature profile under continuous hydrogen flow. After annealing, the material exits through a sealed unloading chamber. Throughout the process, hydrogen sensors and safety interlocks continuously monitor the atmosphere to ensure safe, stable operation.
