Аннотация: It is known that the main factor that determines the dispersity of atomization of particles of a metal powder is the blast energy, which is regulated, as a rule, by the speed of supply of the gas-energy carrier to the jet of the melt. The purpose of this work was to study technological regimes and the development on the basis of coПоказать полностьюmputer simulation of technological equipment for dispersing powders of soldering aluminum alloys. For its achievement, technical and technological features of the scheme for obtaining powders from aluminum alloys intended for soldering waveguides are considered. A computer study was carried out in the package of the engineering analysis of Solidworks Flow Simulation of the influence of the geometry of the structural components of the tooling on the parameters of the melt dispersion AK12C10. It was assumed that the velocity of the gas jet - argon at a temperature T = 20 ° C at the site of collision with the melt should be maximum with all other conditions being equal (initial pressure, temperature of the gas and melt). Dependencies necessary and sufficient for the design of structural elements of equipment and technological regimes providing the realization of conditions for the stable flow of the process of metal melt dispersion when obtaining a predetermined value of the powder fraction of 70 μm are established. on a laboratory installation. A description is given of a laboratory apparatus for dispersing a melt of AK12C10, on which a pilot batch of a 70 μm powder with a mass of 400 g was produced and transferred to the JSC «ISS» them. acad. M.F. Reshetnev for industrial tests when soldering aluminum waveguides.
