The invention provides an equipment and technology for preparing superfine spherical
metal powder by means of
ultrasonic vibration and atomization. The
metal powder is prepared by adopting a stepless speed-regulation
ultrasonic vibration wire feeding
system and a vacuum
electron beam generator or multiple
plasma generators to melt and atomize
metal materials in a combined mode. The equipment comprises a vacuum atomizing chamber and a
barrel thereof, the upper portion of the
barrel is communicated with a
vacuum pumping exhaust pipeline and the
electron beam generator, the left end of the
barrel is provided with a front door, the right end of the barrel is provided with a vacuum atomizing chamber rear door, the outer surface of a
powder accumulation hopper, the outer surface of the barrel and the outer surface of the vacuum atomizing chamber front door are each coated with a cooling
water jacket, and an auxiliary mechanical chamber is defined by an atomizing chamber interlayer arranged inside the barrel and the vacuum atomizing chamber rear door. According to the equipment and technology for preparing the superfine spherical
metal powder by means of
ultrasonic vibration and atomization, two
metal powder preparation methods are combined into a whole and selectively used, continuous long-time large-capacity production can be achieved through only one-time starting, and the produced powder is high in purity, fine in particle size, centralized in distribution and significant in spherical appearance characteristic; the equipment occupied space is small, operation is easy, the investment is low, and the running cost is low.
