    Abstract: In a process of cooling and solidifying molten metal particles, gas substantially free from nascent and molecular oxygen (argon, helium, nitrogen, carbon dioxide and carbon monoxide) is bubbled through a liquid, thereby creating at the surface of the liquid a layer of foam of bubbles containing some of the gas. Additional gas is retained in the space adjacent the foam. Molten metal particles are formed by being centrifugally projected through holes extending through a side wall of a rotating pot disposed within the space. The molten particles are decelerated and cooled by passing into said foam, and rupture some of the bubbles, so that the gas contained within them flows into the space. The particles then leave the foam and pass into the liquid, becoming further cooled, and are thereafter recovered solidified, substantially unoxidized, and with a minimum of distortion, thereby being suitable for forming into strip. New gas-containing bubbles are created by bubbling additional gas through the liquid, so as to maintain the layer of foam.
