Abstract

The invention discloses a rotary magnetic field magnetizing apparatus for a neodymium-iron-boron radiation ring magnet, relates to the field of a radiation direction of the neodymium-iron-boron radiation ring magnet, particularly applicable to saturation magnetization of a sintered neodymium-iron-boron large-diameter radiation ring, and particularly relates to a novel radiation magnetic field generation structure with a rotatable magnetic field framework. The rotary magnetic field magnetizing apparatus mainly comprises a rotary magnetic field magnetizing machine main body, a hydraulic oil cylinder, and an electrical system. By adoption of the rotary magnetic field magnetizing apparatus, the problem that the radiation magnetic field magnetization of the sintered neodymium-iron-boron large-diameter radiation ring cannot be realized is solved; the produced sintered neodymium-iron-boron large-diameter radiation ring can be used as a magnetic levitation bearing and a petrochemical engineering pipeline accessory for extending a petroleum hydrocarbon chain to reduce oil transport resistance, so that the application of the sintered neodymium-iron-boron large-diameter radiation ring is expanded and promoted.

Description

technical field [0001] The invention relates to the field of magnetization in the radiation direction of an NdFeB radiation ring magnet, and is especially suitable for saturation magnetization of sintered NdFeB large-diameter radiation rings, and particularly relates to a new structure for magnetizing a radiation magnetic field with a rotatable magnetic field frame. Background technique [0002] Sintered NdFeB large-diameter radiation ring magnets above 80mm can only be magnetized in radial directions at present, and there is no effective method for magnetizing in radial directions. Therefore, it is a key goal of the industry to develop a device that can magnetize the radiation direction of large-diameter radiation ring products. Contents of the invention [0003] The purpose of the present invention is to propose a magnetizer with a brand-new structure, which is used to produce large-diameter radiation ring magnets that are not currently available in the market for magnet...
