| titleOfInvention | A kind of method that waste and old device performance of sintered NdFeB recovers |
| abstract | The present invention relates to a kind of method for recovering the waste and old device performance of sintered NdFeB.The waste and old device of sintered NdFeB removes water demagnetization removal of impurities through oil removing and goes the processes such as corrosion-resistant coating cleaning-drying vacuum melting to obtain (Nd, R) x (Fe, M) y B z (R refers to substitution Nd heavy rare earth metal Dy, Tb etc. to alloy；M refers to substitution Fe Co, Nb, Ga, Cu, Al etc.).Alloy produces sintered NdFeB device, realizes performance recovery " from the old to the new " with 1~10% new raw material dispensing.The advantage of the invention is that：Technological process is short, and metal recovery rate is high, and energy consumption is low；Equipment is simple, reduced investment, and obtained alloy can be directly used for producing neodymium iron boron, and added value is high；Whole process does not produce waste water, and tail gas is free of nuisance, and after slag recovery valuable constituent, finishing slag is harmless, available for doing building materials.Whole method integrated cost is low, green, can create huge economic and social benefit. |
