FIELD: metallurgy.
SUBSTANCE: intermediate device contains tank with bottom consisting of section of metal melt and slag being. Specified tank sections are connected to each other in the bottom part of tank by means of channel with temporary overlap. Presence of temporary overlap is defined by time of metal melt and slag being in appropriate section. Input of channel for metal discharge and side channel for slag discharge are located at height h1 and h2, at that h1<h2.
EFFECT: receiving of ultrapure steel at the expense of minimisation ingress of furnace slag with metal into ladle.
