Abstract

PURPOSE:To obtain a magnet of quickly cooled fine powder having excellent magnetic properties by forming ferromagnetic powder by blowing inert gas flow under injecting pressure of 50kg/cm<2> or more to melted rare earth element- transition metal element-boron alloy flow. CONSTITUTION:Melted ferromagnetic alloy (rare earth elementtransition metal element-boron alloy) M having predetermined composition is melted in a high frequency melting furnace 2. The melted alloy M is fed out from a melted alloy nozzle 4 at the bottom of the furnace by the operation of a stopper 3. A slender melted alloy flow from the nozzle 4 is quickly cooled to be formed in fine powder by blowing inert gas of high pressure (50kg/cm<2> or more) injected from a primary nozzle 5. The quickly cooled alloy formed in fine powder is dropped while being further cooled by inert gas flow injected from a secondary nozzle 6, and recovered in a lower cyclone 7. Thus, a magnet of quickly cooled fine powder having excellent magnetic properties is obtained.
