摘要： A process of producing granules of a reactive metal. The process comprises providing a source of molten reactive metal (41), forming discrete droplets (53) of the molten metal, contacting the droplets while still substantially molten with a fluidized bed of particles (12) maintained at a temperature substantially below the solidus temperature of the metal and freezing the droplets as discrete granules of the reactive metal in the fluidized bed. The invention also provides apparatus for carrying out the method and product produces by the method, including a magnesium-containing additive for aluminum alloying. The use of a fluidized bed for cooling and freezing the droplets avoids problems encountered in prior methods and also makes it possible to provide coatings of various kinds on the surfaces of the granules, if desired.

摘要： An atomizing method for producing metal powder, including splitting molten metal in the vicinity of an exit of a nozzle by introducing the molten metal into a center of the nozzle, wherein gas is flowing through the nozzle. The split molten metal is then further split into fine particles by liquid ejected in an inverse cone shaped flow from a slit surrounding a lower side of the nozzle. The resulting powder is of fine size and spherical or granular shape, and is suitable for metal injection shaping.

摘要： Spherical balls, notably microballs of welding alloys, are produced by passing a melted material through vibrating orifices of a granulation pot, in order to form droplets which solidify when falling, by gravity, into a cooling tower filled with an inert gas. To improve the surface condition of the balls, the inert gas comprises approximately 15 to 150 ppm of oxygen. Moreover, the melted material is subject to ultrasound stirring just before being fed into the granulation pot. The balls are, preferably, dampened at the outlet of the cooling tower by brushes composed of polyamide wires. Besides, the control of the vibration frequency of the vibrating orifices in relation to the percentage of balls meeting the standards enables to improve the output.
