Embodiment 1

[0038] The continuous vacuum ingot casting equipment of a kind of silver alloy of present embodiment is as figure 1 and figure 2 As shown, it includes a vacuum chamber 1 and a crystallizer 5. The vacuum chamber 1 is provided with a graphite crucible 3, the wall of the graphite crucible 3 is provided with a heating device, and the bottom of the graphite crucible 3 is provided with a liquid silver outlet. The silver liquid outlet is connected with the crystallizer 5, and the periphery of the crystallizer 5 is provided with a cooling device 8, and the liquid silver liquid outlet is provided with a traction device for drawing liquid silver to the crystallizer and pulling out the solid silver formed in the crystallizer , the pulling device is located in the crystallizer 5, and can move up and down in the crystallizer 5.

[0039] The device has a simple structure and is easy to operate.

[0040] The working principle of this embodiment is:

[0041] Put four silver plates with a...

Embodiment 2

[0062] The continuous vacuum ingot casting method of a kind of silver alloy of the present embodiment is to utilize the continuous vacuum casting equipment of a kind of silver alloy of embodiment 1, and concrete operation steps are as follows:

[0063] The sealing flange 52 is locked to seal the crystallizer 5,

[0064] The drawing die 75 is arranged on the liquid silver liquid outlet of the graphite crucible 3, and the liquid silver liquid outlet is sealed at the same time, so that the silver ingot is heated by the heating device in the vacuum chamber 1 to fully melt into liquid silver,

[0065] Then loosen the sealing flange 52,

[0066] The hydraulic system drives the traction mold 75 to move down to the crystallizer 5 through the connector 72 and the traction rod 71. The traction speed of the hydraulic system is 80mm / min. The hydraulic system is outwardly drawn by 5mm and then retracted by 2mm. Repeat this continuously.

[0067] Once the liquid silver in the drawing die 7...

Abstract

The invention relates to the technical field of metal casting, in particular to a continuous vacuum casting device and method for silver alloy. The device comprises a vacuum cavity and a crystallizer. A crucible is arranged in the vacuum cavity. A heating device is arranged on the wall of the crucible. A liquid silver outlet is formed in the bottom of the crucible and communicated with the crystallizer. A cooling device is arranged on the periphery of the crystallizer. A traction device used for dragging liquid silver to the crystallizer and dragging formed solid silver in the crystallizer out is arranged at the liquid silver outlet and located in the crystallizer and can move vertically in the crystallizer. The device is simple in structure and convenient to operate. Continuous vacuum casting of silver alloy can be achieved. According to the casting method, continuous silver alloy casting under the vacuum environment can be achieved, and the operation process is simple and easy to achieve.

Description

technical field [0001] The invention relates to the technical field of metal casting, in particular to continuous vacuum ingot casting equipment and an ingot casting method for silver alloys. Background technique [0002] In general industrial production, most smelting is carried out in a non-vacuum state. Silver absorbs a large amount of oxygen in a molten state. In a molten state, silver can dissolve oxygen 21 times its own volume. This property of silver gives smelting and Casting brings difficulties, it makes the silver alloy easy to volatilize at high temperature or splash from the high temperature cooling process, resulting in a lot of loss, and in the smelting process, it is easy to infiltrate other impurity elements, and the final smelted silver ingot has many defects ,low quality. [0003] In order to solve the above technical problems, vacuum is generally used to cast silver alloys. There is a silver alloy vacuum ingot casting equipment in the prior art, which inc...
