FIELD: metallurgy.
SUBSTANCE: proposed device comprises tube including working end wall extending enlarged part, said working end is immersed into fused electrolyte in tapping. Wall enlarged part helps minimise remaining electrolyte entrainment from interface electrolyte/metal in tapping. Said enlarged wall section may be directed along the ladle main direction.
EFFECT: ruled out mixing of electrolyte with metal, in particular, aluminium in tapping from electrolyser.
