Latest Patents

Jingdong Jia's latest patents include the "Nd–Fe–B sintered magnet and methods for manufacturing the same." This invention pertains to a sintered neodymium-iron-boron magnet, which comprises rare-earth elements, additional elements, iron, and boron. The magnet features a rare-earth-enriched phase and a main phase of a Nd2Fe14B crystal structure. The invention ensures that the sum of the maximum magnetic energy product (BH)max and the intrinsic coercive force Hcj is not less than 70. The manufacturing method involves alloy smelting, powder making, powder mixing, press forming, sintering, and heat treatment procedures. By optimizing the component formulation and process conditions, the magnet achieves both a high maximum magnetic energy product and a high intrinsic coercive force.

Another notable patent is the "Apparatus for preparing alloy sheet." This apparatus includes a container for melted alloy liquid positioned in an inductive heating coil, along with a liquid flow stabilization outfit. The design features a quenching wheel that spins the melted alloy liquid into strips, which then become alloy sheets after collision. This innovation allows for good orientation of the magnetic material, ease of post-sinter processing, and suitability for mass production.
