| titleOfInvention | Method for spheroidizing meltable powder |
| abstract | The invention relates to a method for spheroidizing meltable powder, which is characterized by comprising the following steps: (1) replacing air in the meltable powder by using nitrogen-hydrogen reducing gas; (2) preheating and heating the meltable powder in sequence; (3) heating to 235-245 ℃, pushing the powder to the bottom of a barrel-shaped container with tin liquid inside to mix with the tin liquid, and uniformly dispersing; (4) the powder starts to float under the action of buoyancy, the melting and spheroidizing temperature which is suitable for the powder is selected at 250-2200 ℃, and the meltable powder is heated to melt and spheroidize into spheres in the floating process; (5) floating the formed powder balls, cooling and solidifying, accumulating on the surface of molten tin, and overflowing or sucking out and collecting. The invention has the advantages that: the spheroidizing method has wide range of spheroidizing powder materials, can be organic high polymer material powder and also can be inorganic non-metal material powder, and the surface of a sphere extruded and polished by tin liquid has higher smoothness and is more compact in the floating process. |
