摘要： A method for controlling a ladle to pour molten metal into a sprue of a mold. The method includes obtaining a mathematical model describing a locus of positions where the molten metal flowing from the ladle drops on an upper surface of the sprue. The method further includes solving an inverse problem of the mathematical model, estimating a position where the molten metal drops using a result of the solving of the inverse problem, and determining target voltages to be supplied to servomotors controlling the ladle. At least the target voltage to be supplied to one of the servomotors is determined based on the estimated position. The method also includes controlling the servomotors based on respective target voltages.

摘要： The purpose of the present invention is to provide a method for accurately dropping molten metal that flows from a ladle into a pouring gate in a mold. The present invention includes a method for controlling the respective input voltages transmitted to a servomotor that tilts the ladle such that the molten metal that flows from the ladle drops accurately into the pouring gate in the mold, a servomotor that moves the ladle back and forth, and a servomotor that moves the ladle up and down, by using a computer. In the method, a mathematical model of the area on which the molten metal that flows from the ladle will drop is produced, and then the inverse problem of the produced mathematical model is solved. In view of the effect of a contracted flow, the position on which molten metal drops is estimated by the estimating device for estimating the pouring rate and the estimating device for estimating the position on which molten metal will drop. Then the estimated position is calculated by a computer. Thereby the respective input voltages transmitted to the servomotor that tilts the ladle, the servomotor that moves the ladle back and forth, and the servomotor that moves the ladle up and down, are obtained. Then the three respective servomotors are controlled based on the obtained input voltages.

摘要： A method of automatically pouring molten metal from a ladle into a mold by tilting the ladle. In the method, the height of molten metal located above a molten metal outlet and the weight of molten metal flowing out of the ladle are estimated using an expanded Kalman filter on the basis of: the weight of the molten metal flowing out of the ladle, said weight being measured using a load cell; the voltage inputted to a servo motor; the angle of tilt of the ladle measured by a rotary encoder; and the position of the ladle in the lifting and lowering direction thereof. The sum of the weight of the molten metal flowing out of the ladle when the ladle is tilted rearward, said weight being estimated from the angle of tilt of the ladle and the height of the molten metal located above the molten metal outlet estimated by the expanded Kalman filter, and the weight of the molten metal flowing out of the ladle estimated by the expanded Kalman filter are estimated as the final weight of outflowing molten metal. The estimated final weight of outflowing molten metal is determined whether or not to be greater than or equal to a specific weight of outflow, and the operation of rearward tilting of the ladle is started on the basis of the result of the determination.

摘要： A tilting-type automatic pouring method for pouring molten metal from a ladle with an outflow position into a mold. The method includes tilting the ladle forward to pour molten metal into the mold, measuring a weight of poured molten metal, calculating a flow rate of the molten metal flowing out of the ladle based on the measured weight of poured molten metal, estimating a weight of molten metal that will be poured during a backward tilting. The method also includes estimating a total weight of molten metal based on the measured weight of poured molten metal and the estimated weight of molten metal that will be poured during the backward tilting and comparing the estimated total weight of molten metal to a predetermined weight. When the estimated total weight is equal to or larger than the predetermined weight, the backward tilting is started.

摘要： An electromagnetically driving part for use in opening/closing a valve or the like, comprises a guide cylinder 17 in which a movable core 18 is received slidably, and a fixed core 15 fixed to the guide cylinder 17. The fixed core 15 and the guide cylinder 17 are coupled with each other by welding in a state that the guide cylinder 17 is press-fitted onto the fixed core 15. An air gap 16a is formed between an outer circumferential surface of the fixed core 15 and an inner circumferential surface of the guide cylinder 17. The fixed core 15 and the guide cylinder 17 are welded with each other in a portion where the air gap 16a is formed. Accordingly, it is possible to weld a guide cylinder and a fixed core with each other surely, and to miniaturize an electromagnetically driving part.
