The present invention provides pouring equipment of a tilting-type that can appropriately pour molten metal at a high speed corresponding to the speed of molding. It also provides a method of pouring the molten metal. The pouring equipment has a holding furnace supplying the molten metal by being tilted, a pouring ladle pouring the molten metal supplied from the holding furnace into molds that are intermittently transported, a device for measuring weight of the molten metal in the pouring ladle, and equipment for control that controls the tiltings of the holding furnace and the pouring ladle. The equipment for control has a device for storing results from measurements and devices for calculating the first and second flow rate. The equipment controls the tilting of the ladle so that the ladle pours the molten metal into the mold according to the flow pattern of the product.

Pouring equipment and method of pouring using the pouring equipment

Provided herein is an automatic pouring method and equipment for the same that enable to inhibit the generation of residual molten metal in a ladle and thus the molten metal to be discharged therefrom can be eliminated. The method includes the steps of determining a set weight of the molten metal to be received in the ladle and number of pieces of the molds that could be poured with the ladle based on data on assigned numbers of respective molds to be poured, types of products to be cast, and set weights of the molten metal to be poured, receiving a weight of the molten metal that is greater than the set weight of the molten metal in the ladle, deriving a difference in weight between the actual weight of the molten metal that is received in the ladle and the set weight of the molten metal in the ladle, deriving a target weight of the molten metal to be poured by adding a part of the derived difference in weight to the set weight of the molten metal to be poured into the mold to be poured, and pouring the molten metal into the mold to be poured to target the target weight of the molten metal to be poured. The pouring of the molten metal is repeated by number of times that equals to the number of pieces of the molds that could be poured with the ladle such that the ladle would be emptied when the last mold in the number of pieces of the molds that could be poured with the ladle is poured.

Automatic pouring method and facility therefor

An automatic pouring method whereby a tilting automatic pouring device can pour at high speed, accommodating high-speed molding on a high-speed molding line. The method includes: a step wherein a pouring hopper, which can hold an amount of molten metal sufficient for multiple pours, is tilted forward, thereby pouring the molten metal from the hopper into a casting mold; a step wherein the pouring hopper is tilted backward, thereby stopping the aforementioned pouring into the casting mold; and a step wherein a set of casting molds, including the casting mold for which the aforementioned pouring has been completed, are moved at intervals. During the period from the beginning of the step in which molten metal is poured into the casting mold to the end of the step in which the set of casting molds is moved at intervals, whenever the weight of molten metal in the pouring hopper is less than a prescribed weight, molten metal is continually supplied to the pouring hopper by tilting a holding furnace forward.
