[0056] The cooling base 7 is provided with a cavity. The cooling base 7 is provided with a cooling medium inlet 9 and a cooling medium outlet 8 respectively connecting the cavity with the outside of the outer cylinder 2. The outer cylinder 2 is also provided with an air inlet 10 and an outlet Port 17;

[0057] A clamp 4 is sleeved on the outer wal...

Example Embodiment

[0079] Example 2

[0080] The structure of the integrated device for melting and casting of the gold-based alloy casting billet is the same as that of the first embodiment.

[0081] 1. The lifting rod is inserted into the socket, not connected to the socket;

[0082] 2. The magnetic stirring device is a permanent magnet stirring device, which is arranged at the bottom of the outer cylinder;

[0083] 3. The material of cooling base 7 is heat-resistant stainless steel;

[0084] The method of use is the same as in Example 1, the difference is:

[0085] 1. Apply current to the heating induction coil through the high-frequency power supply to generate a magnetic field, and heat the metal material in the crucible through the magnetic field; to prevent splashing, first preheat Al, Y, In, Co, Cu and Zn to 200°C ; When the Au in the crucible is melted, use the feeding rod to press Al, Y, In, Co, Cu and Zn into the Au melt through the feeding port to carry out the alloying process of the gold-bas...

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...
