Experimental Hydrogen Decrepitation Furnace

Core Features

1. Advanced Heating System: Utilizes a round tube-type hollow heating furnace with resistance wire heating, capable of reaching a maximum operating temperature of 600°C within 60 minutes.
2. High Vacuum Capability: Achieves an ultimate vacuum of 1×10-1 Pa (in cold, empty state) and maintains a low pressure rise rate, ensuring optimal processing conditions.
3. Precise Temperature Control: Offers temperature uniformity of ±3°C within a 500 mm zone, with PID controllable silicon temperature regulation for accurate process control.
4. Automated Control System: Features PLC programming for interlocking protection, computer-controlled temperature, and automated processes including leak detection, hydrogen absorption, dehydrogenation, and cooling.
5. Safe and Reliable Design: Equipped with multiple safety features including over-temperature shut-off, over-pressure alarm, water failure shutdown protection, and hydrogen leak detection.

Advantage

1. Versatility: Suitable for processing a range of materials, including coarse-broken particles and cast pieces, with specific oxygen and nitrogen content limits.
2. Efficiency: Optimized for short processing cycles, with a typical work cycle of no more than 12 hours for normal neodymium-iron-boron material.
3. Automation: Fully automated processes reduce manual intervention, enhancing safety and repeatability.
4. High-Quality Construction: Built with durable materials and advanced technology to ensure long-term reliability and precision.
