Abstract
A pouring ladle (12) includes a horizontal chamber (22) having an inlet (24) at one end thereof for admitting molten metal into the chamber (22) and a bottom-poured nozzle (28) at an opposite end for discharging the metal into an underlying mold (30). A coreless induction heater (56) surrounds the chamber (22) for heating metal as it flows from the inlet (24) to the outlet nozzle (28). The induction heater (56) may be operated simultaneously with the pouring of metal and be used to pour treated ductile iron without plugging the inductor (56).
