PROBLEM TO BE SOLVED: To provide a pouring method by which molten metal flowing from a ladle is accurately fallen into a spout in a mold. SOLUTION: In this method, input voltages to be impressed to a servo-motor for tilting the ladles that the molten metal flowing from the ladle is accurately fallen into the spout in the mold, a servo-motor for moving the ladle to the front and rear direction and a servo-motor for vertically moving the ladle are controlled by using a computer. A mathematical model of the dropping locus for molten metal flowing from the ladle is prepared, a reverse model of the made mathematical model is solved, the falling position of the molten metal is estimated by a falling rate estimating part and a falling position estimation part, and the falling position data is processed by the computer to acquire the input voltages to be impressed to the servo-motor for tilting the ladleso that the molten metal flowing from the ladleis accurately fallen into the spout in the mold, the servo-motor for moving the ladle to the front and rear direction and the servo-motor for vertically moving the ladle, therebycontrolling these three serbo-motor based on the acquired inpu voltages.
