| titleOfInvention | Method for producing R-Fee- 희 rare earth magnetic powder for bonded magnet, magnetic powder produced by this method and method for producing bonded magnet using the magnetic powder, bonded magnet produced thereby |
| abstract | The present invention relates to a method for producing a R-FE-Ｂ rare earth magnetic powder for bonded magnets, a magnetic powder prepared by the same, and a method for producing a bonded magnet using the magnetic powder, and a bonded magnet manufactured by the same. Coarsely pulverizing the phosphorus rare earth sintered magnet product (step 1); A hydrogenation process step (step 2) of charging the pulverized product produced in the step 1 to a vacuum tube furnace and filling hydrogen and raising the temperature of the tube; A phase decomposition step (step 3) of further raising the temperature in the tube in the same hydrogen atmosphere as in step 2; Hydrogen discharge process step (step 4) for exhausting the hydrogen in the tube furnace of step 3; And a recombination process step (step 5) of evacuating the hydrogen pressure in the tube furnace after performing step 4, and a method of manufacturing magnetic powder with improved magnetic properties, thereby improving the magnetic properties. Provided are a magnetic powder prepared and a method for producing a bonded magnet using the magnetic powder, and a bond magnet manufactured thereby. Through the present invention, it is possible to manufacture a magnetic powder having a fine size and uniform composition to improve magnetic properties, and it is advantageous in terms of cost and environmental aspects by recycling waste scrap at low cost. |
