Abstract
A method for controlling the respective input voltages transmitted to a servomotor that tilts the ladle such that the molten metal that flows from the ladle drops accurately into the pouring gate in the mold, a servomotor that moves the ladle back and forth, and a servomotor that moves the ladle up and down, by using a computer. In the method, a mathematical model of the area on which the molten metal that flows from the ladle will drop is produced, and then the inverse problem of the produced mathematical model is solved. In view of the effect of a contracted flow, the position on which molten metal drops is estimated by the estimating device for estimating the pouring rate and the estimating device for estimating the position on which molten metal will drop.
