FIELD: metallurgy.
SUBSTANCE: ceramic fire-resistant lock to regulate liquid metal flow contains a casing 12 with lock plug 14, in which a cylindrical insert 30 is located. In the casing a gas supply line 16 is made, it passes to the cylindrical gas channel 38 concentric to the central longitudinal axis of lock.
EFFECT: gas flow passing through the ring channel has high temperature, this excludes melted metal solidification and block of the gas channel in plug.
