FIELD: chemical industry; metallurgy.
SUBSTANCE: invention relates to the chemical industry and metallurgy, to liquid granulation and is intended for the production of spherical granules of substances of various degrees of purity, including multicomponent solid solutions and compounds, metals and alloys. The device for granulating substances contains a reactor consisting of a housing 2 and a lid 1 connected to an inert gas supply system, with a crucible 5 placed inside with at least one hole, and the hole in the crucible 5 is designed to drain the molten substance 4 with simultaneous filtration, a furnace unit 3 covering the reactor housing in the placement zone of the crucible 5, flasks of the first 7 and second 11 cooling circuits, with the lower edge of the reactor housing immersed in the flask 7 with coolant 6 of the first cooling circuit, placed inside the flask 11 of the second cooling circuit, pre-filled with refrigerant 10 that is water, a coolant with a density of 1.2 to 0.7 g/cm3 is used as the coolant 6 of the primary circuit, the reactor is filled with an inert gas with excess pressure, providing the bubbling process and the circulation of inert gas through a liquid gate formed by the lower edge of the reactor housing 2 and the coolant 6 of the primary circuit, and crucible 5 is made of a material that is not wetted by the melt of the initial substance, but wetted by its oxides.
EFFECT: expansion of the arsenal of tools and the creation of a universal device for granulation of substances (metals or alloys), which can be used for a wide class of materials, materials of various degrees of purity, including high-purity, provided that equipment, basic and auxiliary materials of the required quality and appropriate preparation for the process are used.
