| 20090090483 | Control of casting machine - Control is provided over the pouring of iron in the casting of iron pipe in a centrifugal casting machine. The initial flow of molten iron from the pouring ladle into the trough actuates an electric eye. A second electric eye is actuated when the molten iron has filled the pouring ladle. The centrifugal casting machine is rolled up to surround the trough, the bell end of the pipe to be formed being at the end of the trough. The molten iron is poured into the casting machine trough and flows into the bell section of the pipe being cast. The casting machine is then moved away from the trough end to form the rest of the pipe. | 04-09-2009 |

| 20100108285 | DEVICE FOR LOW-PRESSURE CASTING, A METHOD FOR FILLING INERT GAS IN THE DEVICE, AND METHOD FOR PRODUCING A CAST - The object of the present invention is to provide a device for low-pressure casting wherein the stalk or the guiding hole is filled with inert gas by causing the space formed over the molten metal in the pressurizing room to communicate with the stalk or the guiding hole. The device for low-pressure casting ( | 05-06-2010 |
| 20120097359 | AUTOMATIC FOR AUTOMATIC POURING - Provided is an automatic pouring method whereby even a tilting automatic pouring device can pour at high speed, accommodating high-speed molding on a high-speed molding line. Said method includes: a process wherein a pouring tank, which can hold an amount of molten metal sufficient for multiple pours, is tilted forward, thereby pouring the molten metal from inside said tank into a casting mold; a process wherein the pouring tank is tilted backward, thereby halting the aforementioned pouring into the casting mold; and a process wherein a set of casting molds, including the casting mold for which the aforementioned pouring had completed, are moved at intervals. During the period from the beginning of the process in which molten metal is poured into the casting mold to the end of the process in which the set of casting molds is moved at intervals, whenever the weight of molten metal in the pouring tank is less than a prescribed weight, molten metal is continually supplied to the pouring tank by tilting a holding furnace forward. | 04-26-2012 |

| 20140262118 | CENTRIFUGAL CASTING METHOD AND APPARATUS - A method and apparatus for centrifugal casting, in which transfer functions are developed relating the fluidity of molten metal, for example iron of varying composition, to casting machine movement for a particular mold in order to cast objects, for example pipe, having desired and uniform characteristics, including wall thickness. Fluidity is calculated for each pour of molten metal based on the measured pour temperature and measured liquidus arrest temperature. A drive system controlled by a programmable logic controller moves the casting machine in accordance with the output of the transfer functions based on the calculated fluidity. | 09-18-2014 |
| 20140262119 | INTERMITTENT MOLTEN METAL DELIVERY - Automated processes that dynamically control rate of delivery of molten metal to a mold during a casting process. Such automated processes can use dynamic metal level variation, control pin pulses and/or oscillation during the mold fill and transient portion of the cast. It has been found that such pulses keep metal flowing in a manner that addresses problems, particularly at the beginning of an ingot cast, associated with metal meniscus contracting and pulling away from the mold on the short faces and corners. | 09-18-2014 |
| 20140262120 | CENTRIFUGAL CASTING METHOD AND APPARATUS - A method and apparatus for centrifugal casting, in which transfer functions are developed relating the fluidity of molten metal, for example iron of varying composition, to casting machine movement for a particular mold in order to cast objects, for example pipe, having desired and uniform characteristics, including wall thickness. Fluidity is calculated for each pour of molten metal based on the measured pour temperature and measured liquidus arrest temperature. A drive system controlled by a programmable logic controller moves the casting machine in accordance with the output of the transfer functions based on the calculated fluidity. | 09-18-2014 |
| 20150290708 | TILTING GRAVITY CASTING APPARATUS AND TILTING GRAVITY CASTING METHOD - In a tilting gravity casting apparatus, a die includes a ladle that stores a molten metal and the molten metal is poured through a runner into a cavity of the die when the die is tilted. The apparatus includes a block member for blocking the runner, a pressing pin for pressing the molten metal in the cavity, a controller that controls operation of driving the block member and the pressing pin, and a first molten metal sensing sensor disposed in the runner. The controller is configured to start driving the block member and the pressing pin based on a detection signal outputted from the first molten metal sensing sensor. | 10-15-2015 |
| 20160023270 | DIE CASTING APPARATUS AND DIE CASTING METHOD - In a die casting apparatus, during feeding of molten metal by an electromagnetic pump, a molten metal level sensor repeatedly detects a during-feeding level of the molten metal stored in a molten metal holding furnace; a control unit corrects a molten metal feeding voltage to a during-feeding voltage based on the repeatedly detected during-feeding level of the molten metal such that an amount of the molten metal fed by the electromagnetic pump coincides with a prescribed amount; the control unit applies the during-feeding voltage to the electromagnetic pump to cause the electromagnetic pump to feed the molten metal from the molten metal holding furnace into a plunger sleeve; and casting is performed through an injecting operation in which the molten metal fed into the plunger sleeve is extruded by a plunger tip to be injected into a cavity. | 01-28-2016 |
