A study was made of centrifugal atomization of molten metals in argon at low argon consumption rates [(5.2-7.5) · 10 NTP m/kg]. Output with a single injector attained 30-40 kg/h. Increasing the molten metal head to 0.6-0.8 MPa and decreasing the nozzle diameter to 0.3 mm substantially increased the fineness of the powders. Raising the head still further influenced the effectiveness of atomization to a smaller extent, and decreasing the nozzle diameter to less than 0.3 mm coarsened the powders. Powders of magnesium, aluminum, and Br020 alloy. (20% Sn-Cu bronze) produced by centrifugal atomization of superheated (by about 30-50°K) melts in an inert atmosphere (argon) had spherical particle shapes, which imparted to them good flowability. The oxygen content of the powders was low (less than 0.08%). [ABSTRACT FROM AUTHOR] |
