Vacuum Heat Treatment Furnace

The Rotary Vacuum Heat Treatment Furnace embodies advanced engineering and innovative features tailored for efficient and uniform hydrogen crushing, dehydrogenation, and cooling processes of NdFeB materials. The hydrogen crushing furnace plays a crucial role in the production of NdFeB permanent magnets, enabling the creation of high-performance magnetic materials with superior magnetic properties.

Core Features and Advantages

1. High Automation & Reliability: Horizontal operation with no tilting, controlled by software for safe, accurate monitoring.

2. Innovative Design: Independent filter system, platform guides for space, and three-stage temp control for efficiency.

Efficient Cooling & Work Environment: Combined natural, air, spray, and immersion cooling reduces steam and radiation.

3. Uniform Production: Handles large volumes (1200kg NdFeB), with a rotating chamber and gas injection for mixing.

4. Advanced Safety: Four layers of overpressure protection, dual temp control, and real-time monitoring for safe operation.

Applications:

The Hydrogen Cracking Furnace is specifically designed for the hydrogen crushing and dehydrogenation processes of NdFeB materials. It is widely used in the production of high-performance permanent magnets for applications in electric vehicles, wind turbines, and other industries requiring high efficiency and reliability.

5. Control System: PLC programmable controller, touch screen interface for intelligent control

6. Safety Devices: Maximum working pressure 0.096MPa, with three levels of safety control

Program and control

1. Start vacuum, negative pressure leak detection, hydrogen filling, argon filling when negative pressure occurs, heating, cooling, furnace opening and closing and other fully automatic operations.

2. Use vacuum instruments that are not affected by the medium, alarm when dehydrogenation is abnormal (such as leakage) and automatically stop heating and argon filling.

3. When hydrogen is filled, if the gas supply is insufficient or fails, when the pressure drops to 0.01MPa, argon is automatically added to 0.04MPa.

4. When discharging, there is a discharging speed setting on the touch screen.

5. When adding, dehydrating and discharging, the manual button is prohibited. The opening and closing of the electric furnace is also interlocked.

6. Human-machine interface: touch screen, temperature, pressure, vacuum display and recording.
