The present invention provides a tilting-type automatic pouring method wherein a very speedy and highly accurate pouring can be realized, which method pours molten metal into a mold by tilting a ladle that holds the molten metal, and the present invention also provides the storage medium for programs used for the method.
The tilting-type automatic pouring method of the present invention uses a) the relationship of (1) the height of the molten metal during backward tilting of the ladle, which height is calculated from the height of the molten metal above the outflow position, which height decreases, when the forward tilting of the ladle stops and from the height of the molten metal that is above the outflow position and that decreases after the backward tilting of the ladle starts, and (2) the weight of the molten metal poured from the ladle into the mold, and b) the model expression for the flow of the molten metal, which expression defines the weight of the molten metal that flows from the ladle into the mold.
In the tilting-type automatic pouring method of the present invention, the final weight of the molten metal that is poured is estimated by assuming that the final weight of the molten metal that is poured from the forward tilting of the ladle to its backward tilting is equal to the sum of the weight of the molten metal that is poured at the start of the backward tilting and the weight of the molten metal that is poured after the start of the backward tilting.
