Abstract: A twin roll casting system includes a pair of counter-rotating casting rolls having an adjustable nip therebetween, a casting roll controller configured to adjust the nip between the casting rolls in response to control signals; a cast strip sensor measuring a parameter of the cast strip and generating strip measurement signals; and an iterative learning control (ILC) controller receiving the strip measurement signals and providing control signals to the casting roll controller. The ILC controller includes a fault detection algorithm receiving the control signals and the strip measurement signals and generating a fault detection signal indicating when a fault condition is detected and an iterative learning control algorithm to generate the control signals. The fault detection algorithm indicates a fault condition when it detects the control signal exceeding an upper control saturation threshold or the ILC controller operating a state that is not guaranteed as stable.

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 sprue of a mold to decrease.

Abstract: Automated processes that dynamically control rate of delivery of molten metal to a mold during a casting process. Such automated processes can use dynamic metal level variation, control pin pulses and/or oscillation during the mold fill and transient portion of the cast. It has been found that such pulses keep metal flowing in a manner that addresses problems, particularly at the beginning of an ingot cast, associated with metal meniscus contracting and pulling away from the mold on the short faces and corners.

Abstract: A shaped metal casting made in an aggregate mold comprises fine solidification microstructure that is finer than the solidification microstructure of an analogous metal casting made from conventional molding processes. The solidification microstructure may be up to five times finer than the solidification microstructure of a conventionally prepared casting. In preferred embodiments, as a result of directional solidification, the fine solidification microstructure is substantially continuous from a distal end of the casting to a proximal end of the casting, and exhibits greatly enhanced soundness. Because of the control of the uniformity of freezing of the casting, its properties are substantially uniform.

Abstract: The vertical filling level of electrically conductive material in a cavity of a metallurgical vessel is measured by a system including a transmitting conductor for generating an electromagnetic field when connected to an alternating power source, and a receiving conductor which senses the electromagnetic field for generation of an output signal. The conductors are arranged inside a metal casing of the vessel to co-extend with a mutual spacing defining a spacing area that faces the cavity and extends along the periphery in an essentially closed loop. The mutual spacing is selected such that changes in the output signal is dominated by changes to the electromagnetic field caused by local changes in the amount of the conductive material adjacent the spacing. Part of the spacing area defines a vertical measurement region slanted along the periphery so as to diverge from the horizontal and vertical directions of the vessel.
