FIELD: metallurgy.
SUBSTANCE: invention relates to the field of metallurgy and can be used in out-of-furnace processing of liquid steel in a steel ladle. The device contains a steel-pouring ladle, at least one combined hearth electrode with holes for injecting inert gas, a current lead combined with an inert gas supply path, and a current-carrying distribution manifold with an opening for inert gas supply. A safety valve is installed in the upper part of the collector, made in the form of a plug made of refractory material, and a water-cooled cavity with a spiral insert is made outside the collector.
EFFECT: invention makes it possible to increase the reliability and safety of operation of a ladle with metal bottom blowing.
