FIELD: technological processes.
SUBSTANCE: invention relates to the field of additive technologies, in particular to production of large-size ingots from aluminum alloy with equiaxial crystalline grain. Device for manufacturing large-size ingots from aluminum alloy with equiaxial crystalline grain using additive technology with matrix sputtering it contains the liquid aluminum spraying mechanism arranged in the atmospheric pressure chamber and the movable condensation mechanism and the control mechanism located under it. Liquid aluminum spraying mechanism comprises an inlet mechanism, a liquid aluminum chamber and an array of nozzles located at the bottom of the liquid aluminum chamber. Movable condensation mechanism comprises a condensation table located opposite a matrix of nozzles, device for two-dimensional movement of condensation table in horizontal directions and guide device for movement of condensation table in vertical direction. Aluminum alloy ingot is obtained by heating to liquid aluminum chamber to liquid aluminum temperature and maintaining it, filling the chamber with liquid aluminum, nozzles are heated, the chamber is evacuated and the liquid aluminum is sprayed and the ingots are cooled on the condensation table.
EFFECT: obtaining an ingot with a structure in the form of an equiaxial crystal without macroscopic segregation.
