What is nanocrystalline core vacuum annealing furnace?

Nanocrystalline core vacuum annealing furnace is a high-precision heat treatment equipment that performs annealing in a vacuum atmosphere, effectively conduct vacuum crystallization annealing and stress relief annealing for nanocrystalline cores or amorphous cores.

1. Main Structure of vacuum annealing furnace

1）Vacuum Chamber: Sealed furnace body, water-cooled to prevent deformation.

2）Vacuum System: Mechanical pump + diffusion/molecular pump to achieve high vacuum.

3）Heating System: Uses graphite, molybdenum, or tungsten heaters. Temperature range 650°C, and temperature control accuracy: ±1℃.

4) Cooling System: Natural cooling or forced gas cooling (N₂/Ar), and cooling rate adjustable from 5 to 20℃/min.

5) Control System: PLC for precise temperature programming, vacuum and timing control.

2. The Advantages of vacuum annealing furnace

1) Simple structure and easy maintenance with low routine inspection costs.

2) No oxidation or decarburization under vacuum, ensuring a smooth workpiece surface.

3) Stable process and excellent parameter repeatability for mass production.

4) Vacuum annealing furnace is cost-effective, which could meet mass production requirements for standard products.
