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.

The present invention relates to the production field of casting technique, in particular to an automatic pouring method and system for a heat preserving furnace pouring platform. By collecting an inclined effluent angle of a heat preserving furnace of the heat preserving furnace pouring platform, a pouring reference datum angle of the heat preserving furnace satisfying the pouring amount is obtained. If the inclined angle of the heat preserving furnace is equal to the pouring reference datum angle, the heat preserving furnace stops inclining. After a predetermined time, a molten steel image from a diversion trench discharge hole to a pouring mold gate is collected, and a molten steel flow velocity value is obtained according to the molten steel image. The extracted molten steel flow velocity value is compared with a corresponding predetermined velocity range. When the molten steel flow velocity value exceeds the corresponding predetermined velocity range, the inclined pouring angle of the heat preserving furnace is adjusted to control the flow velocity of the molten steel within the corresponding predetermined velocity range, so as to solve the problems of the existing technology that the inaccurate control on the pouring angle causes molten steel waste when the heat preserving furnace automatically pours, and the pouring efficiency is low.

The present invention provides a tilting-type automatic pouring method wherein a very speedy and highly accurate pouring can be realized, which method pours molten metal into a mold by tilting a ladle that holds the molten metal, and the present invention also provides the storage medium for programs used for the method.

The tilting-type automatic pouring method of the present invention uses a) the relationship of (1) the height of the molten metal during backward tilting of the ladle, which height is calculated from the height of the molten metal above the outflow position, which height decreases, when the forward tilting of the ladle stops and from the height of the molten metal that is above the outflow position and that decreases after the backward tilting of the ladle starts, and (2) the weight of the molten metal poured from the ladle into the mold, and b) the model expression for the flow of the molten metal, which expression defines the weight of the molten metal that flows from the ladle into the mold.

In the tilting-type automatic pouring method of the present invention, the final weight of the molten metal that is poured is estimated by assuming that the final weight of the molten metal that is poured from the forward tilting of the ladle to its backward tilting is equal to the sum of the weight of the molten metal that is poured at the start of the backward tilting and the weight of the molten metal that is poured after the start of the backward tilting.
