In a casting device, positions of discharge ends discharging cooling gas, of respective gas supply nozzles are adjusted in response to movement of a mold. This makes it possible to stably achieve high cooling performance for the mold by blowing of the cooling gas. To adjust the positions of the respective discharge ends, the gas supply nozzles are advanced or retreated, or are expanded or contracted. Further, a cooling chamber may include a radiation cooling portion that cools the mold by radiation, and the radiation cooling portion is disposed below the gas supply nozzles that are provided directly below a heat shielding body partitioning a heating chamber and the cooling chamber.

Steam exhaust ports are located around a perimeter of a direct chill casting pit, at various locations from below the top of the pit to the pit bottom to rapidly remove steam from the casting pit with addition of dry excess air. Gas introduction ports are also located around a perimeter of the casting pit and configured to introduce an inert gas into the casting pit interior.

In a casting device, when a mold varied in outer size depending on a position passes through a heat shielding portion between a heating chamber and a cooling chamber, a flexible portion of a heat shielding body is bent to fit the outer size of the mold.

Methods of manufacturing a semiconductor processing chamber showerheads may include forming a melted aluminum alloy composition, cooling the melted aluminum alloy composition at a rate of at least 103 K/sec to form solid aluminum alloy particles, and forming a core region of a showerhead from the solid aluminum alloy particles. The core region of the showerhead may include an inner core region and an outer core region that may be coupled together. The inner core region may define a plurality of apertures. The outer core region may define a channel that receives a heating element. The methods may include coating the core region with one of aluminum or aluminum oxide and joining a peripheral edge of the outer core region with an inner edge of a metallic annular liner. The metallic annular liner may have a lower thermal conductivity than the core region of the showerhead.

A casting apparatus for manufacturing a cast product from molten metal includes a molten metal and a cooling portion. The molten metal contacts a surface for contact with the molten metal. The cooling portion forms a cooling flow passage. The cooling flow passage is configured to cool the molten metal contacting surface. At least a part of an inner surface of the cooling flow passage is constituted of a welding portion formed by welding, the welding portion sealing the cooling flow passage. The welding portion is constituted such that an exposure to the molten metal becomes equal to or less than a predetermined ratio with respect to an area of the welding portion constituting the inner surface of the cooling flow passage.

A casting and outputting system is provided. The system includes a casting machine, a disc body, a transfer device, a special fixture, a cooling tank, a collection device and a waste plate rack. The transfer device is configured to drive the special fixture to take out anode plates cast on the disc body, place a qualified one of the anode plates in the cooling tank, place an unqualified one of the anode plates on the waste plate rack, lift the anode plate cooled in the cooling tank, and place the cooled anode plate on the collection device for stacking.
