Abstract

The invention discloses a gold base alloy casting blank melting and casting integrated device and a utilization method thereof. The gold base alloy casting blank melting and casting integrated device comprises a melting pot, a fireproof material cylinder, a cooling base, an outer cylinder, a heating induction coil and a magnetic stirring device. The utilization method of the gold base alloy casting blank melting and casting integrated device comprises putting gold into the melting pot and inserting the melting pot into the fireproof material cylinder; piping inert gas or reducing gas into the outer cylinder; heating the metal inside the melting pot to be melted through magnetic fields, adding other metal or alloy and performing alloying; enabling the melting pot with the fusant to descend to an annual boss of the cooling base and cooling the fusant to cast the fusant which is gradually solidified from bottom to upper during the cooling process. The gold base alloy casting blank melting and casting integrated device has the advantages of being simple in structure, convenient to operate and low in integral cost and enabling prepared gold base alloy to be uniform in ingredient and less in internal defect. The gold base alloy casting blank melting and casting integrated device and the utilization method thereof have good application prospects.

Description

technical field [0001] The invention belongs to the technical field of material processing equipment, and in particular relates to an integrated melting and casting device for a gold-based alloy billet and an application method thereof. Background technique [0002] Since the 1990s, the electron source has been used to generate electrons, which are accelerated and focused in a vacuum to form a high-speed energy particle beam to bombard the solid surface (target). The magnetron sputtering technology in which the atoms on the surface of the target are excited and deposited on the surface of the substrate to form a coating has many advantages such as high film formation density, good adhesion, and environmental protection. At present, it has become a hot spot of research and development and attention in the field of new materials at home and abroad. [0003] As a new functional material, gold-based alloy not only maintains the original characteristics of pure gold, such as cor...
