Tilting-type automatic pouring method and storage medium

A storage medium that comprises programs that operates a computer wherein the backward tilting of a ladle is started, by using a model expression for the flow of molten metal that flows from the ladle into a mold, and estimating the final pouring weight,

• wherein the computer comprises and operates as following means:
• a storage means that stores the model expression for the flow of the molten metal;
• a calculating means that calculates the angle of the tilting of the ladle when it actually starts pouring the molten metal, based on the angle of the tilting of the ladle when it should start pouring, which angle is determined by a load cell;
• a calculating means that calculates the volume of the molten metal in the ladle at the start of pouring, based on the angle of the tilting of the ladle when it actually starts pouring;
• a calculating means that calculates the height of the molten metal in the ladle during the backward tilting of the ladle, which height is calculated based on the difference between the height of the molten metal above the outflow position, when the forward tilting of the ladle stops, and the height of the molten metal that is above the outflow position and that decreases after the backward tilting of the ladle starts;
• a calculating means that calculates the weight of the molten metal that is poured after the start of the backward tilting of the ladle;
• a calculating means that calculates the weight of the molten metal poured at the start of the backward tilting of the ladle;
• a converting means that converts the weight of the molten metal that flows from the ladle into the mold to the weight of the molten metal that is poured, which the load cell measures as the weight of the molten metal poured;
• a calculating means that calculates the final weight of the molten metal that is poured 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;
• and
• a means to determine whether the final weight that is estimated as the one that should be poured is equal to the predetermined weight to be poured.
