Description of the invention (υ The centrifugal vacuum cavity protected by the present invention, semi-deposition and other operations are all made in series), tight and meticulous holes, etc.), it is not easy and low to shape the cavity and mechanical Add and lose, and change the gas to dissolve in the defect of 孑 L, adopt the phenomenon of general dissociation, but the traditional alloy centrifugation is studied from this, research and design, and the design of the near-net true design, especially the mention of its casting technology The method is guided by a true continuous casting to intercept the whole, and then the user needs to make the required method. Because of the high cost and time-consuming gravity casting, the solid casting is also made by centrifugal casting The inventor finally created a cavity, which provides a centrifugal casting aluminum alloy with high temperature and high temperature process, and a forging alloy casting embryo that operates in the ion cavity by using the bottom pouring method and gas. The block material is first forged and mechanically processed (the rough cavity of the vacuum cavity; the thickness per embryo (> 200mm) is about 80%). If you want to improve this method, However, because the solubility of the high temperature body is reduced, it is not suitable to be made by gravity. Although it has a large scale, the film is rolled and clamped in the molten metal, and it is suitable for the manufacture of a vacuum chamber. In order to greatly improve the transfer, etching and epitaxy of the habit, the vacuum cavity such as AA6 0 6 1, AA5XXX makes its crystal structure more like turning, milling, and drilling. It is mechanically processed into a larger size, making the material larger. If it is taken, it will cause various defects in the production rate. Lu alloy metal liquid will easily produce pores and shrinkage. If there is no pressure, there will be turbulence, and defects such as debris, so Experience. 'After continuous casting, but the production is lacking, this is a centrifugal casting aluminum alloy vacuum for this hair.

Description of the invention (2) The method for making the lunar body is after the Ming alloy ingot is heated and refined into a metal liquid, and an inert gas is injected into the pouring tank to reduce oxides. The method of generating and reducing m at the bottom reduces the impact of molten metal flow to reduce the inclusion of inclusions. In addition, the purpose is to provide a method for fabricating a centrifugal casting alloy vacuum cavity. Among them, y · », under the hair, and around the rotating metal mold; Reduction of oxidation = protected inert gas, which can reduce the demand of the near-net vacuum cavity milk =, and the molding conforms to characteristic i.
