Abstract: To enable a ladle-tilting automatic pouring device to take less time for identification of the parameters and the device to pour highly precisely by sequentially updating pouring model parameters according to the pouring situation, the present pouring control method is based on a mathematical model of a process from input of control parameters to pouring of molten metal, the method including: identifying, using an optimization technique, a flow rate coefficient, a liquid density, and a pouring start angle that is a tilting angle of the pouring ladle when the flowing of the molten metal starts, which are the control parameters in the mathematical model, based on weight of liquid that flows out of the pouring ladle and tilting angle of the ladle that are measured during pouring, and a command signal that controls the tilting of the pouring ladle; and updating the control parameters to the identified control parameters.

Abstract: A method for managing a casting process based on measured properties of molding sand is provided so that casting defects or energy used can be reduced by changing the molding conditions for the mold to be produced or changing the steps after molding. The method for managing a casting process based on the properties of the molding sand comprises a step (1) of measuring the properties of the molding sand just before the molding sand is supplied to a molding machine (40) and a step (2) of determining if the measured properties of the molding sand comply with predetermined properties, wherein, if by the step of determining it is found that the measured properties do not comply with the predetermined properties, a mold is molded to have less strength than that of a mold that is molded by using molding sand whose properties do comply with the predetermined properties.

Abstract: To provide a machine and method for efficiently pouring and definitely filling only a desired cavity with molten metal to cause the molten metal to solidify there. The automatic pouring machine (1) that has an ability to pressurize having a ladle (2) for pouring molten metal into a mold (A) comprises a pouring unit (10) that can move a ladle in the direction parallel to, and in the direction perpendicular to, a line (L) of molds where a plurality of molds are transported and a unit (20) for pressurizing the molten metal that is supported by the pouring unit and that supplies pressurized gas and a granular material to the mold into which molten metal has been poured. The unit (20) supplies the pressurized gas and the granular material to the mold that is next to the mold into which the pouring unit pours molten metal.
