Title:
AUTOMATIC POURING METHOD AND FACILITY THEREFOR
Document Type and Number:
WIPO Patent Application WO/2010/146909
Kind Code:
A1
Abstract:
Disclosed are an automatic pouring method and a facility therefor obviating the needs to drain the molten metal to be drained from the ladle by preventing the molten metal from remaining in the ladle. The method includes a step of determining a set weight of the molten metal received by a ladle and the number of molds into which the molten metal can be poured from the ladle on the basis of data about the mold numbers of the molds, the type of the products to be cast, and the set weight of the molten metal to be poured, a step of allowing the ladle to receive the molten metal the weight of which is more than the set weight of the molten metal, a step of calculating the difference between the actual weight of the molten metal received by the ladle and the set weight of the molten metal, a step of calculating a target weight of the molten metal by adding part of the calculated difference in weight to the set weight of the molten metal poured into a mold to be supplied with the molten metal, and a step of pouring the molten metal into the mold to be supplied with the molten metal using the target weight of the molten metal as a target. Pouring the molten metal is repeated multiple times corresponding to the number of molds into which the molten metal can be poured by means of ladle, and the ladle is emptied after the molten metal is poured into the last one of the number of molds into which the molten metal can be poured.
