FIELD: metallurgy, namely melt metal casting.
SUBSTANCE: ladle bottom includes large numbers of steps and ducts for guiding flow of melt metal to outlet opening of ladle. Steps are designed for retaining slag and ducts provide metal movement towards outlet opening.
EFFECT: enhanced efficiency of draining metal out of ladle, lowered quantity of rejected metal, elimination of early draining of slag through outlet opening, reduced degree of contamination by slag of melt metal discharging from ladle.
