20090188644 | CONTROL METHOD FOR SUPPLYING INERT GAS DURING METAL MOLDING - A control method for supplying an inert gas from an inert gas source to a storage container for a molten metal through a gas feed path provided with a flow sensor for monitoring the gas flow rate and a solenoid valve for opening and closing the gas feed path for use with metal molding. The control method comprises; turning off the solenoid valve at a temperature of the storage container is equal to or lower than a preset temperature, and turning off the flow sensor; turning on the solenoid valve at the temperature of the storage container has reached the preset temperature, and turning on the flow sensor; and stopping the output of the heater of the storage container when a flow rate of the inert gas is equal to or lower than the preset amount; these steps are controlled in accordance with a command signal from a controller. | 07-30-2009 |
20100132906 | METHOD OF CASTING A METAL ARTICLE - During the casting of the metal article, a mold is lowered from a furnace assembly into a body of an inert gas. A stream having a thermal conductivity greater than the thermal conductivity of the inert gas is directed against a first portion of the mold to initiate solidification of molten metal in the first portion of the mold. The stream is subsequently directed against portions of the mold disposed in the body of inert gas and disposed above the first portion of the mold to initiate solidification of molten metal and portions of the mold above the first portion of the mold. The stream may be formed of a molten metal. Alternatively, the stream may be formed of an inert gas in which particulate is entrained. | 06-03-2010 |
20100212855 | CASTING PROCESS FOR ALUMINUM ALLOYS - The invention relates to a casting process for an aluminum alloy containing at least about 0.1% of Mg and/or at least about 0.1% of Li in which a liquid surface of said alloy is put into contact with a dried gas including at least about 2% of oxygen by volume and with a water partial pressure lower than about 150 Pa throughout most of the solidification process. | 08-26-2010 |
20100236745 | APPARATUS AND METHOD FOR RECYCLING MAGNESIUM ALLOY SCRAP - The present invention is directed, in general, to an apparatus for recycling magnesium alloy scrap. In particular, an apparatus for recycling magnesium alloy scrap includes a melting furnace formed with a tapping part, having a first filter for removing impurities present in molten scrap, and capable of being tilted toward the tapping part; a first cleaning furnace disposed on a side of the melting furnace, having a gas injecting part for injecting an inert gas in the molten metal and capturing and removing impurities present in the molten metal, and capable of being tilted; a second cleaning furnace disposed on a side of the first cleaning furnace, and having a pump to tap a predetermined amount of the molten metal supplied from the first cleaning furnace and a second filter to remove impurities in pumped molten metal; and an ingot forming furnace disposed on a side of the second cleaning furnace, and configured to form an ingot using the predetermined molten metal supplied from the second cleaning furnace. | 09-23-2010 |
20110186259 | Utilization of Carbon Dioxide And/Or Carbon Monoxide Gases in Processing Metallic Glass Compositions - A method of forming an iron based glass forming alloy. The method may include providing a feedstock of an iron based glass forming alloy, melting the feedstock, casting the feedstock into an elongated body in an environment comprising 50% or more of a gas selected from carbon dioxide, carbon monoxide or mixtures thereof. | 08-04-2011 |
20130032304 | POUR LADLE FOR MOLTEN METAL - A method of forming a casting using a casting apparatus is disclosed, the method including the steps of lowering a ladle having a hollow interior into a source of molten material and an aperture facilitating flow into the hollow interior, filling the interior of the ladle with the molten material through the aperture, introducing an inert gas into a portion of a nozzle, removing the ladle from the source of molten material, causing the nozzle to contact a casting mold, and pressurizing the hollow interior with an inert gas to cause the molten material to flow into the casting mold. | 02-07-2013 |
20130206351 | FORMING METAL PREFORMS AND METAL BALLS - A process and tools for forming and/or releasing metal preforms, metal shapes and solder balls is described incorporating flexible molds or sheets, injection molded metal such as solder and in the case of solder balls, a liquid or gaseous environment to reduce or remove metal oxides prior to or during metal (solder) reflow to increase surface tension to form spherical or substantially spherical solder-balls. | 08-15-2013 |
