FIELD: process engineering.
SUBSTANCE: invention relates to method and device for adding powder to fluid metal. Method of mixing powder with fluid metal comprises adding powder to fluid metal in its mixing. Fused metal in source 14 under reduced pressure in crucible 12 wherein fused metal is displaced flows from source 14 upward via bypass tube 6. Powder is dispensed from container 1 and displaced by gas. Mix of powder and gas are added to fused metal in bypass tube 6 for mixing therein and feeding into crucible 12. Mixing device has source 14 to feed fused metal and powder container 1. Source 14 is communicated via bypass tube with container arranged above and kept at reduced pressure. Carrier gas feed control unit 4 communicated with mixing chamber 3 nearby outlet of powder container 1. Mixing chamber 3 is communicated with bypass tube 6 to feed powder into fused metal in bypass tube.
EFFECT: better mixing.
