specific Embodiment approach 1

[0007] Embodiment 1: This embodiment is a spray deposition method with optional metal droplet size. The existing spray deposition method is to fill the molten metal 1 in the crucible 6, with reference to figure 1 , the injection cavity 7 is set under the crucible 6, the molten metal 1 is sprayed out through the nozzle 3 at the lower end of the crucible, atomized by the atomization system 10 and then sprayed onto the ingot 4 for deposition. Since the existing spraying method cannot separate the metal droplets of different particle sizes, the metal particles of different sizes sprayed from the nozzle 3 after atomization can only be sprayed on the billet without selection. Affects the deposition quality, so this embodiment connects the molten metal 1 in the existing spray deposition equipment to the charge source 2, the purpose is to charge the molten metal 1, and then charge the molten metal 1 in the molten metal nozzle of the existing spray deposition equipment An electric fie...

specific Embodiment approach 2

[0008] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the setting of the electric field is that one metal plate 8 is connected to the positive pole of the power supply, the other metal plate is connected to the ground, and the metal plate is connected to the ground instead of the negative pole. The connection has the advantages of being convenient, simple and easy to operate.

specific Embodiment approach 3

[0009] Embodiment 3: This embodiment differs from Embodiments 1 and 2 in that a magnetic field is used instead of an electric field. The molten metal 1 in the spray deposition equipment is connected to the charge source 2, referring to image 3 , A magnetic field is set between the molten metal nozzle 3 and the ingot 4, and the direction of the magnetic field is perpendicular to the extension line of the molten metal nozzle 3 axis. The magnet described in this embodiment is a permanent magnet, refer to image 3 , Figure 8 , the N pole and S pole of the permanent magnet are respectively arranged on both sides of the 3-axis extension line of the molten metal nozzle, so that a magnetic field is generated between the N pole and the S pole, and the magnetic field force will have an impact on the ejected charged metal particles Make it deflect, so as to achieve the same purpose of separating metal particles with different particle sizes as in the first embodiment. Similarly, in ...

Abstract

The ejecting and sediment method choosing the size of the metal liquid drop deals with the ejecting sediment method. Aiming to the drawback of existing ejecting sediment method incapable of gain the high quality billet, the invention provides the ejecting sediment method of choosing the size of the metal liquid drop, the metal melting liquid (1) and the charge source (2) in the ejecting sediment setting are connected, the electric field or the magnetic field or the electromagnetism field is fixed between the nozzle (3) and the billet (4), the direction of the electric field and the magnetic field is vertical with the prolonged line of the axes of the metal melting drop nozzle (3), the placed electric field power and the magnetic field power of the metal liquid drop gushed from the nozzle (3) are controlled to reach the reverse direction. The invention adopt the restricting method of connecting the electric field, the magnetic field or the electromagnetism field, the metal liquid drop ejected from the ejecting sediment can be separated, the separated little size of the metal liquid drop is used for producing the billet to improved the quality of the billet highly.

Description

technical field [0001] The invention relates to a spray deposition method. Background technique [0002] The existing spray deposition method can only do simple spray forming. For the atomized metal droplets of different sizes, the existing spray deposition method does not have the separation function. As we all know, when the size of the metal droplet deposited on the billet The quality of the billet will only improve when it is uniform and finer. However, the existing spray deposition method cannot separate the atomized metal droplets with different particle sizes, that is, the metal droplets with different particle sizes sprayed after atomization All must be deposited on the billet, which makes the product quality can not be improved. Contents of the invention [0003] Aiming at the disadvantage that the existing spray deposition method cannot obtain high-quality ingots, the present invention provides a spray deposition method that can separate metal droplets in the sp...
