AUTOMATIC POURING METHOD AND STORAGE MEDIUM STORING LADLE TILTING CONTROL PROGRAM

Title:

AUTOMATIC POURING METHOD AND STORAGE MEDIUM STORING LADLE TILTING CONTROL PROGRAM

Document Type and Number:

WIPO Patent Application WO/2007/119697

Kind Code:

A1

Abstract:

A method for controlling the automatic pouring by tilting the ladle enabling the pouring to approximate to that by a skilled worker by a computer where a program is previously installed. A method for controlling the servo motor to pour a molten metal by a ladle into a mold in a desired pouring flow pattern when a ladle is tilted to pour the molten metal into the mold by the servo motor controlled by a computer in which a program for performing pouring process is installed. The method is characterized in that a mathematical model from the input voltage to the servo motor to the pouring flow by the ladle is made, the inverse problem of the mathematical model made is solved, the input voltage to the servo motor is determined, and the servo motor is controlled according to the determined input voltage.
