Abstract

<PICT:1022995/C6-C7/1> Lead shot or small spheres of other metals is made by heating the metal above its melting point, feeding it to the downwardly directed outlet of a nozzle to allow successive spherical droplets to form and fall from the outlet, causing the droplets to pass immediately into and through a non-aqueous coolant liquid having a viscosity, specific gravity and temperature such that the droplets are substantially solidified on passing therethrough without distortion of their shape, and allowing the droplets to pass into a body of cooling water which directly supports the non-aqueous liquid. The non-aqueous liquid may be a light weight thin oil or it may be paraffin oil or kerosene to which a small quantity of mineral oil may be added. Metal is melted in a pot A and flows under control of a valve B to a receptacle C in which it is heated to maintain a desired constant temperature by an electric immersion heater, a tubular element D, which may also be heated, feeds a plurality of nozzles E from which the metal flows in the form of droplets under control of adjustable needle valves F. The droplets fall through non-aqueous cooling liquid J in tank H and then into the underlying water layer K. The solidified metal spheres collect on the sloping bottom of the tank and can be removed from the open topped, water-filled part L. The non-aqueous cooling liquid can be circulated through a heat-exchanger to maintain a constant temperature difference between it and liquid metal droplets.ALSO:<PICT:1022995/C1/1> Glass spheres are made by heating the glass above its melting point, feeding the melt to a downwardly directed outlet of a nozzle to allow successive spherical droplets to form and fall from the outlet, causing the droplets to pass immediately into and through a non-aqueous cooling liquid having a viscosity, specific gravity and a temperature such that the droplets are substantially solidified without distortion of their shape on passing therethrough, and allowing the droplets to pass into a body of cooling water which directly supports the nonaqueous liquid.
