Abstract
To enable a ladle-tilting automatic pouring device to take less time for identification of the parameters and the device to pour highly precisely by sequentially updating pouring model parameters according to the pouring situation, the present pouring control method is based on a mathematical model of a process from input of control parameters to pouring of molten metal, the method including: identifying, using an optimization technique, a flow rate coefficient, a liquid density, and a pouring start angle that is a tilting angle of the pouring ladle when the flowing of the molten metal starts, which are the control parameters in the mathematical model, based on weight of liquid that flows out of the pouring ladle and tilting angle of the ladle that are measured during pouring, and a command signal that controls the tilting of the pouring ladle; and updating the control parameters to the identified control parameters.
