(863) 247-31-81 Statistics Granulation of liquid metals is carried out by spraying molten metal and is the simplest and fastest way to manufacture metal powders with a melting point of up to 1600 C: aluminum, copper, zinc, lead, nickel and other metals and alloys. The melt crushing process consists in crushing the stream of the melt with a liquid or mechanical atomization. For spraying, the metal is melted in electric furnaces. Depending on the properties of the molten metal and the requirements for the quality of the powder, spraying is carried out with air, nitrogen, argon, helium, and for protection against oxidation - with an inert gas. The main parameters of the spraying process: pressure and temperature of the gas flow, temperature of the melt. The cooling medium for the spray jet can be water, gas, organic liquid. Under different spraying conditions, droplet powder particles are obtained, spherical and other shapes. Particle sizes are obtained from 1 mm to hundredths of a millimeter. Of the various available methods of metal processing, powder metallurgy occupies a special place, since it makes it possible to obtain not only products of various shapes and purposes, but also to create fundamentally new materials, which are either very difficult or impossible to obtain in another way. Such materials can have unique properties, and in some cases the economic performance of production is significantly increased. With this method, in almost most cases, the metal recycling rate is almost 100%. Bronze Brass Copper Saturday, 08/19/2017
