At present, in the process of crushing and pulverizing sintered neodymium iron boron, because the saturated magnetic polarization intensity of sintered neodymium iron boron powder is high, the rare earth content is low, and heavy rare earth is not present, the agglomeration force among the powder is high, particularly the powder is easy to be held together to form large particle clusters among the powder, and oversized crystal grains are formed in the sintering process, so that the magnetic performance of the product can be seriously influenced, and a large potential safety hazard exists.
The prior sintering NdFeB powder production device for preventing agglomeration needs to adopt the following measures:
1. powder dispersion treatment: during the powder preparation process, the raw materials need to be finely crushed and mixed to ensure uniform distribution of the individual components in the powder.
2. Oxidation prevention: in the preparation process of sintered NdFeB powder, inert gases such as argon are needed to prevent oxidation, and harmful gases such as carbon dioxide are avoided.
3. Reducing the temperature: in the sintering process, the sintering temperature needs to be controlled so as not to exceed the melting point of the sintered NdFeB material, so as to avoid melting and agglomeration of the material.
4. And (3) hot pressing preparation: the sintering process can be completed at lower temperature and pressure by adopting a hot pressing preparation method, so that melting and agglomeration of materials are avoided.
5. Surface treatment: after sintering, the surface treatment is carried out on the NdFeB magnet, so that the agglomeration tendency of the material can be further reduced, and the stability and the service life of the magnet are improved.
In summary, the device for producing sintered neodymium iron boron powder for preventing agglomeration needs to take various measures in the preparation process to ensure uniform distribution of powder components, avoid oxidization and overhigh temperature, complete the sintering process by a hot pressing preparation method, and perform surface treatment on the magnet, thereby improving the stability and the service life of the magnet.
