Abstract

A group of the inventions relates to the field of metallurgy, in particular to a method for processing liquid metal in the ladle furnace and a device for realization thereof. The method includes a circulating vacuum pumping liquid metal in the chamber with a vertical partition and simultaneous blowing thereof with gases through the side wall in the increasing space above the surface of liquid metal in the ladle-furnace, at that the liquid metal is continuously mixed with gas in the plasma state from the heating zone of its electric arc through the vacuumized chamber with a vertical partition in the ladle and reagents are supplied on the surface of vacuumized liquid metal. A device for the realization of this method includes a ladle-furnace with liquid metal, lid and electrode(s) in it, the lid set with circulating vacuum vessel with the batcher for reagents and immersed plasmotron in the cavity of the mentioned vacuum vessel, the suction pipe of which is submerged into the volume of the liquid metal, heated with the electric arc. The inventions provide the increasing metal quality due to its efficient refining with gas-reagent media in vacuum without time limit of metal treatment.
