Abstract
Способ переработки отходов производства постоянных магнитов, содержащих преимущественно редкоземельные и переходные металлы, включающий восстановление отходов производства, их измельчение, прессование и спекание, отличающийся тем, что, с целью снижения трудоемкости переработки отходов производства постоянных магнитов, содержащих бор, повышения качества переработки и улучшения условий труда, восстановление ведут бором при температуре 1673 - 2073 К, а после восстановления производят дошихтовку редкоземельными и переходными металлами при температуре 1673 - 2173 К.The method of processing waste production of permanent magnets containing predominantly rare earth and transition metals, including the recovery of production waste, their grinding, pressing and sintering, characterized in that, in order to reduce the complexity of processing waste production of permanent magnets containing boron, improve processing quality and improve conditions of labor, the restoration is carried out with boron at a temperature of 1673-2073 K, and after the restoration, the rare-earth and transition metals are finished temperature 1673 - 2173 K.
