Abstract: [Problem to Be Solved] A pouring control method for controlling an automatic pouring device with a tilting-type ladle is provided. By the method, a lip of a pouring ladle approaches a sprue of a mold without striking any object located within the range of its movement. Also, by the method, the molten metal that runs out of the ladle can accurately fill the mold. [Solution] The pouring control method comprises the steps of setting a target flow rate of molten metal to be poured, generating a voltage to input it to a motor that tilts the ladle (hereafter, the tilting motor) so as to reach the target flow rate of the molten metal based on an inverse model of a mathematical model of molten metal that runs out of a pouring ladle and an inverse model of the tilting motor, estimating the flow rate of the molten metal that runs out of the ladle, estimating the falling position and getting the estimated falling position to be a target position, and generating a trajectory for the movement of the pouring ladle wherein the trajectory causes the height of the lip of the pouring ladle above the level of a sprite of a mold to decrease.

Abstract: A system (5) and method (800) for unit cell casting of titanium or titanium-alloys is disclosed herein. The system (5) comprises an external chamber (45), a crucible (10) positioned within the external chamber (45), an induction coil (15) positioned around the crucible, an internal chamber (40) positioned within the external chamber (45), and a mold (30) positioned within the internal chamber (40). The external chamber (45) is evacuated and a pressurized gas is injected into the evacuated external chamber (45) to create a pressurized external chamber (45). An ingot (20) is melted within the crucible utilizing induction heating generated by the induction coil (15). The internal chamber (40) is evacuated to create an evacuated internal chamber (40). The titanium alloy material of the ingot (20) is completely transferred into the mold (30) from the crucible (10) using a pressure differential created between the external chamber (45) and the internal chamber (40).

Abstract: Monitoring of a line system (1) in which a liquid medium (3) is guided in a line (2). The current pressure of the liquid medium (3) in the line (2) and in the associated current flow are sensed at sensing times. The two values are fed to a computing unit (5). The computing unit (5) calculates a theoretical flow of the liquid medium (3) in the line (2) from the sensed current pressure by taking into account a specified flow function. The flow function describes a physical relationship between the theoretical flow of the liquid medium (3) and the current pressure of the liquid medium (3). The computing unit (5) determines an individual degree of clogging on the basis of the current flow and the theoretical flow. On the basis of a number of determined individual degrees of clogging and by using stochastic methods, the computing unit (5) calculates an interval within which a degree of clogging of the line system (1) lies with a probability to be defined. The line system (1) is monitored by using the size of the interval and/or the position of the interval with respect to first limits for the degree of clogging that are defined beforehand.

Abstract: Methods and computer-based systems analyze designs for casting parts from molds. An input including that defines a part to be cast is received, including a mold design for the part and/or a set of graphical triangles that visually represent the part. Based on the received design, an undercut region and associated parting line location are determined. The orientation or directionality of the part for the casting may further be determined. Hotspots in the design are further identified. Based on these identified features, feeder dimensions and position are determined for the part to be cast. Directional solidification areas are further identified, and the identified characteristics are output or used to determine improved casting parameter. The part may then be poured into a casting using a mold with the determined characteristics.
