METHOD OF VACUUM REFINEMENT OF LIQUID STEEL IN LADLE Russian patent published in 2009 - IPC C21C7/10

Abstract RU 2348699 C2

FIELD: metallurgy.

SUBSTANCE: invention concerns ferrous metallurgy. Particularly it concerns processing of liquid steel in ladle. Method includes regulation of pressure above the surface of liquid steel and consumption of argon depending on argon content in pumped out gas, changing of carbon monoxide release rate and value of buildup of fluid steel (slag-metal emulsion) in ladle.

EFFECT: excluding of overflow ability of liquid steel over ladle side during the process of vacuum refinement.
