A method for a pouring control and a storage medium for storing programs for causing a computer to carry out a process for controllihg pouring

Abstract

[Problem to be solved] To provide a pouring control method, for a ladle-tilting automatic pouring device, where the operation for identification of the parameters, which normally takes much time to complete, can take less time and the device can pour with a high degree of precision by sequentially updating pouring model parameters according to the pouring situation. [Solution] The present method is a pouring control method for controlling pouring based on a mathematical model of a pouring process from input of control parameters to pouring of molten metal using a pouring ladle in an automatic pouring device with a tilting-type pouring ladle that pours the molten metal into a mold by tilting the pouring ladle that holds the molten metal, and the method comprises: 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 at which flowing out of the molten metal starts, wherein the flow rate coefficient, the liquid density, and the pouring start angle 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.
