PURPOSE: To stably, surely and highly precisely execute automatic pouring of molten metal without the difficulty on the controllability by correcting and setting a molten metal pouring set quantity for every pouring by error portion of preceeding pouring quantity.
CONSTITUTION: The actual load value from a load detector 31 is inputted in a pouring quantity error accumulated value arithmetic unit 36 and the actual load value at this time is stored by a signal before starting the pouring of molten metal. The pouring quantity error accumulated value arithmetic unit 36 stores the actual load value at this time from a signal after completing the pouring of molten metal, and from the actual loaded value at the time of starting the pouring and the actual load value at the time of completing the pouring, the actual pouring quantity at each pouring time is calculated. The difference between the actual pouring quantity and the setting value in a pouring quantity setter 34, i.e., an error accumulated value is obtd. and this value is stored. This error accumulated value is inputted in the pouring quantity setter 34 to set a new pouring quantity setting value at the following pouring of molten metal.
