    Abstract: A roll press method according to an embodiment comprises a roll gap measuring step for measuring a roll gap between an outer peripheral surface of the first roll and an outer peripheral surface of the second roll at one or more positions in a width direction of the first roll while rotating the first roll and the second roll and storing the measured roll gap and rotation angles of the first roll and the second roll in association with each other; and a roll press step for adjusting, according to the rotation angles, a position in the facing direction of the first roll by the adjustment mechanism such that the roll gap is kept within a predetermined variation range with respect to a target value and pressurizing the work by using the first roll in which positions are adjusted in accordance with the rotation angle and the second roll.

    Abstract: A leakage of a molten metal is suppressed at the time of pouring.A control method for an automatic pouring apparatus according to one embodiment includes: calculating a dropping position of a molten metal on a horizontal surface passing through a height position of a sprue, a flow velocity of the molten metal in the dropping position, and a radius of a sectional surface of the molten metal on the horizontal surface, on the basis of a dropping trajectory of the molten metal flowing out from a discharge port, generating an objective function which is relevant to a total weight of the molten metal flowing into a mold from a ladle and depends on a distance between the discharge port and the center of the sprue in a predetermined direction, on the basis of the dropping position, the flow velocity of the molten metal in the dropping position, the radius of the sectional surface of the molten metal on the horizontal surface, a radius of the sprue, a flow rate of the molten metal flowing out from the discharge port, and a density of the molten metal, and calculating the distance between the discharge port and the center of the sprue in the predetermined direction, in which the total weight of the molten metal flowing into the mold from the ladle is maximized, on the basis of the objective function.

    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.
