  • METHOD AND SYSTEM FOR PRODUCING SINTERED NdFeB MAGNET, AND SINTERED NdFeB MAGNET PRODUCED BY THE PRODUCTION METHOD
    Publication number: 20120176212
    Abstract: A method and system for producing a slim-shaped sintered NdFeB magnet having a high level of coercive force and high degree of orientation, as well as a sintered NdFeB magnet produced by the aforementioned method or system. A system for producing a slim-shaped sintered NdFeB magnet according to the present invention includes: a filling unit and filling alloy powder; an orienting unit; a sintering furnace; and a conveying unit. The orienting unit is provided with a heating and orienting coil for heating the alloy powder in the molds before and/or after the application of the magnetic field so as to decrease the coercive force of the individual particles of the alloy powder.
