Abstract

PURPOSE: To eliminate the laboriousness of the adjustment in the rate of supply and improve the evenness of inoculation by leading the inoculant to the supply pipe provided with an addition amount adjusting device and letting the same spout into mold well, molten metal falling part or ladle through the use of high velocity air flow.
CONSTITUTION: The inoculant 1 contained in a storage hopper 2 is sent to an injection nozzle 7 through a supply pipe 4 by an addition amount adjusting device 3. When the air having been heated in a heater 12 is spouted to the molten metal well part 8 of a mold 11 through air pipe 6, the inoculant 1 is carried into the mold 11 by the molten metal 9 which is falling into the mold 11 from a pouring ladle 10, thus it evenly distributes and the inoculation is thereby accomplished. The inoculant 1 is added to the molten metal in the pouring ladle 10 or added to the molten metal 9 which is falling from the ladle 10 into the mold 11.
