Product Overview

The Hydrogen Processing Magnet System Lab Scale is a versatile, bench-top reactor designed for advanced material research and pilot production. It supports hydrogen crushing (HD), nitriding, and HDDR (Hydrogenation-Disproportionation-Desorption-Recombination) reactions – critical processes for developing high-performance rare-earth magnets and titanium alloys. With a maximum loading capacity of 10kg, rated temperatures up to 800°C, and fully automated pressure/flow/vacuum control, this system enables precise atmosphere processing. Whether you are optimizing Magnet Equipment feedstocks or creating next-generation Heavy Duty Magnets, this lab-scale system delivers repeatable results with minimal material waste. An optional CE-certified explosion-proof electrical package ensures safe operation in hydrogen-rich environments.

Product Features & Advantages

• Multi-process compatibility: Supports hydrogen crushing, nitriding, and HDDR reactions in a single system – eliminates the need for separate reactors for each process. Ideal for R&D on Industrial Magnet Solutions.
• Customized atmosphere adaptation: Equipment design and functional expansion can be tailored to specific process requirements (e.g., mixed gases, high-pressure hydrogen, or ammonia for nitriding).
• Precision automatic control: Hydrogen absorption controlled by both pressure and flow; dehydrogenation via automatic vacuum regulation. Achieve consistent reaction kinetics batch after batch.
• Dual cooling system (air + water): Fast cooldown rates (up to 20°C/min) reduce cycle time between experiments – crucial for process development.
• Two-stage safety relief: First relief at 0.2MPa, second at 0.7MPa. Plus power outage protection (automatic argon purge) ensures safe handling of hydrogen-reactive materials.
• Compact lab-scale footprint: Fits on standard benchtop or in a fume hood, yet capable of processing up to 10kg – bridging the gap between small-scale R&D and pilot production.
• CE certification (optional): Explosion-proof electricals meet international safety standards for hydrogen atmospheres.

Why This System for Magnetic Material R&D?

Conventional tube furnaces lack hydrogen flow control and multi-stage safety relief. Our lab-scale system provides industrial-grade automation (pressure/flow/vacuum loops) at a research budget, enabling you to scale up directly from lab to production – whether you are developing Magnetic Lifting Devices or high-coercivity magnet alloys.

Operational Workflow – Step by Step

1. Load material: Place up to 10kg of magnetic alloy (e.g., NdFeB scrap or Ti alloy) into the reactor chamber.
2. Evacuation & purge: Vacuum pump removes air; backfill with inert gas (Ar) to achieve oxygen-free environment.
3. Set process parameters: On HMI, choose mode (hydrogen crushing, nitriding, or HDDR). Input temperature, hydrogen flow/pressure, and hold time.
4. Hydrogen absorption: System automatically introduces hydrogen under controlled pressure (0.1MPa typical) and flow. Reactor rotates or rolls (optional) for uniform exposure.
5. Reaction monitoring: Real-time data logging of pressure drop, temperature, and hydrogen consumption – indicates reaction completion.
6. Dehydrogenation (if required): Switch to vacuum mode; automatic control removes absorbed hydrogen.
7. Cool down: Activate air + water cooling to reach safe handling temperature.
8. Unload & analyze: Discharge processed powder under inert gas. Ready for milling, pressing, or sintering.

Application Scenarios

• Rare-earth magnet development: Hydrogen decrepitation (HD) of NdFeB and SmCo alloys for producing Heavy Duty Magnets with fine, uniform grain structure.
• HDDR process optimization: Produce anisotropic NdFeB powder directly from cast alloy – essential for bonded magnets and Magnet Equipment components.
• Titanium alloy powder (HDH): Hydrogen-assisted cracking of Ti6Al4V for additive manufacturing and MIM feedstocks.
• Nitriding of magnetic materials: Surface modification of soft magnetic alloys for improved corrosion resistance.
• Recycling of magnet scrap: Hydrogen processing of end-of-life magnets to recover high-purity powder for re-use.

Benefits for Customers

• Accelerated R&D: Multi-process capability (HD, HDDR, nitriding) in one system – reduce capital expenditure on multiple reactors.
• Scalable results: 10kg capacity allows direct scale-up to production-scale hydrogen crushers (e.g., 200kg or 1800kg models).
• Enhanced safety: Two-stage pressure relief + power outage protection + optional CE-certified explosion-proof controls – safe for hydrogen handling.
• Higher material utilization: Precise pressure/flow control minimizes over?hydrogenation and powder oxidation, improving yield for expensive rare-earth alloys.
• Process traceability: Full data logging supports ISO 9001 and IATF 16949 compliance – essential for automotive and aerospace supply chains.
• Flexible customization: Atmosphere process requirements can be adapted (e.g., mixed H?/N?, ammonia, or deuterium).
