Title:
AUTOMATIC TILT-POURING METHOD AND STORAGE MEDIUM HAVING LADLE TILT CONTROL PROGRAM STORED THEREON
Document Type and Number:
WIPO Patent Application WO/2011/132442
Kind Code:
A1
Abstract:
Provided is a pouring method for precisely dropping a metal melt, which flows from a ladle, to a pouring gate in a mold. A method which uses a computer to control an input voltage applied to a servo motor that tilts a ladle, an input voltage applied to a servo motor that moves the ladle forward and backward, and an input voltage applied to a servo motor that moves the ladle upward and downward, so as to precisely drop a metal melt that flows from the ladle to a pouring gate in a mold, wherein a mathematical model of the falling path of the metal melt that flows from the ladle is created. The falling position of the metal melt is estimated by means of a pouring velocity estimation unit and a falling position estimation unit, by obtaining the inverse model of the mathematical model and considering the effect of contracted flow. Falling position data is processed by the computer, thereby obtaining the input voltages for the servo motor that tilts the ladle, the servo motor that moves the ladle forward and backward, and the servo motor that moves the ladle upward and downward. The three servo motors are controlled in accordance with the obtained input voltages.
