A water-cooled centrifugal pipe casting machine includes a sector ladle tilting system, a pouring runner, a pipe mold and a pipe removing device. The pipe mold is provided to a travel system, and rotation of the pipe mold is controlled by a pipe mold rotating system. By using a servo motor driving the sector ladle tilting system, by using a parallel four-bar linkage structure tilting a sector ladle, and by using a variable frequency motor controlling the movements of a rack and a gear of a travel driving system, a constant amount of hot metal flowing out of the sector ladle per unit time can be ensured and a constant traveling speed of the centrifugal pipe casting machine are achieved. As such, uniformity of the wall thickness of the casting pipes can be ensured, the quality thereof can be improved, and materials required can be saved.

A casting mold supporting structure is provided herein which includes a support roller for supporting a part of a casting mold that is used in centrifugal casting. The casting mold has a supported surface (that is, a side surface of an end portion of the casting mold which end portion has a circular truncated cone shape) at which the casting mold is supported by the support roller. The supported surface is inclined with respect to a rotation axis of the casting mold.

A system for transporting material is provided. The system includes a container and a robot having a material-handling device for inserting the material into the container and removing the material from the container. The system also includes a track assembly having a track and at least one platform on which the robot and the container are mounted such that the robot and the container are movable along the track via the at least one platform.

A leakage of a molten metal is suppressed at the time of pouring.

A control method for an automatic pouring apparatus according to one embodiment includes: calculating a dropping position of a molten metal on a horizontal surface passing through a height position of a sprue, a flow velocity of the molten metal in the dropping position, and a radius of a sectional surface of the molten metal on the horizontal surface, on the basis of a dropping trajectory of the molten metal flowing out from a discharge port, generating an objective function which is relevant to a total weight of the molten metal flowing into a mold from a ladle and depends on a distance between the discharge port and the center of the sprue in a predetermined direction, on the basis of the dropping position, the flow velocity of the molten metal in the dropping position, the radius of the sectional surface of the molten metal on the horizontal surface, a radius of the sprue, a flow rate of the molten metal flowing out from the discharge port, and a density of the molten metal, and calculating the distance between the discharge port and the center of the sprue in the predetermined direction, in which the total weight of the molten metal flowing into the mold from the ladle is maximized, on the basis of the objective function.

A system and method of manufacturing an aluminum fuel cell cradle includes providing a negative cast mold having cavities to form the cradle and providing a feeding mechanism disposed about the mold and in fluid communication with the cavities thereof. The feeding mechanism includes a plurality of primary risers connected to and in fluid communication with cavities. The method further includes melting a first metallic material to define a molten metallic material, and moving the mold to a vertical casting orientation about a rotational axis, while feeding molten metallic material through the runner to the cavities, and cooling the molten metallic material to define a solidified metallic material. A second solidification time in the risers is greater than a first solidification time in the mold such that shrinkage of the solidified metallic material occurs in the risers away from the mold.
