Description

Technical Field

[0001] The present invention relates to the technical field of gas atomization powder making, and particularly relates to an atomizer diversion tube, an atomizer diversion tube assembly, and an atomizer. Background Art

[0002] The patent with the patent number JP1994025716A (hereinafter referred to as D1) discloses a method for preparing metal powder. In D1, an electric current and a magnetic field are applied to generate a downward Lorentz force on the metal liquid flowing axially in the liquid guide tube, so as to prevent the metal liquid from being blocked due to insufficient flow velocity in the liquid guide tube. D1 also mentions that the electric current flowing through the metal liquid can self-heat and keep warm the metal liquid, which can further prevent blockage.

[0003] However, it is found in actual experiments that when the Lorentz force sufficient to affect the flow velocity of the metal liquid is generated, the self-heating of the metal liquid becomes very serious, which not only affects the quality of the final product, but also reduces the service life of the liquid guide tube. In addition, after the Lorentz force is applied to the metal liquid, it will also cause the turbulence of the metal liquid. Regarding the above defects, D1 was finally withdrawn, and it has not been applied to equipment in the past nearly twenty years, nor is there any further research result or related patent to prove it.

[0004] It is found in the experiment that to generate a Lorentz force sufficient to affect the flow velocity of the metal liquid, the applied current I needs to be between 100 A and 1000 A, and the magnetic field strength B needs to be between 0.25 T and 1 T. That is to say, the applied current needs to exceed 100 A, and the adjustment range and degree of the magnetic field strength B are relatively limited. For those skilled in the art, to solve the problems of overheating and metal liquid turbulence, since the current I cannot be further reduced, only the resistance of the self-heating metal liquid can be reduced. However, the metal liquid in the liquid guide tube is a conductive whole, and the amount of the metal liquid flowing through the liquid guide tube at the same time is also certain, and the resistivity of the metal liquid is also a fixed value, so the size of the resistance of the self-heating cannot be changed, making it infeasible to adjust the size of the resistance of the self-heating metal liquid. Therefore, D1 has technical problems to be solved urgently. Summary of the Invention

[0005] To solve the technical problems existing in the background art, the present invention provides an atomizer diversion tube, which includes a tube body with diversion holes and two embedded components. Two grooves are symmetrically arranged on the inner wall of the tube body with respect to the axial direction of the tube body. Both grooves penetrate one end wall of the tube body and form openings on the end wall. The two embedded components are respectively embedded into the two grooves through the two openings and restore the diversion holes. The embedded component specifically includes a first connection part and a second connection part. Both the first connection part and the second connection part extend from the bottom of the groove to the opening side and are arranged in sequence along the axial direction of the tube body. The first connection part is close to the outer wall of the tube body. The second connection part specifically includes a plurality of first connection units and a plurality of second connection units. The plurality of first connection units and the plurality of second connection units are arranged at intervals in sequence along the axial direction of the tube body. Both the first connection part and the plurality of first connection units are made of high-temperature resistant conductive materials, and the first connection part and the plurality of first connection units are in electrical contact.

[0011] Further, it further includes: a magnetic field generating unit for generating a magnetic field that completely covers or partially covers the area of the diversion hole;

[0012] The current direction, the magnetic field direction, and the axial direction of the diversion tube are perpendicular to each other in pairs, so that when there is molten metal flowing along the axial direction of the diversion tube in the diversion tube, the molten metal generates a Lorentz force distributed along the axial direction of the diversion tube.

[0013] Further, the current direction and magnitude and / or the magnetic field direction and magnitude are adjustable.

[0014] The present invention also provides an atomizer, which is equipped with an atomizer diversion tube or an atomizer diversion tube assembly.

[0028] Embodiment 1

[0029] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9, Embodiment 1 proposes an atomizer flow guide tube assembly, including a flow guide tube, a current generating unit 4, and a magnetic field generating unit 5. The flow guide tube specifically includes a tube body 1 having a flow guide hole 12 and two embedded components 2. Two grooves 11 are axially symmetrically arranged on the inner wall of the tube body 1 relative to the axis of the tube body 1. Both of the two grooves 11 penetrate through one end wall of the tube body 1 and form openings on the end wall. The two embedded components 2 are respectively embedded into the two grooves 11 through the two openings and restore the flow guide hole 12. The embedded component 2 specifically includes a first connection portion 21 and a second connection portion. Both the first connection portion 21 and the second connection portion extend from the bottom of the groove 11 to the opening side and are arranged in sequence along the axis of the tube body 1. The first connection portion 21 is close to the outer wall of the tube body 1. The second connection portion specifically includes a plurality of first connection units 22 and a plurality of second connection units 23. The plurality of first connection units 22 and the plurality of second connection units 23 are arranged at intervals in sequence along the axis of the tube body 1. Both the first connection portion 21 and the plurality of first connection units 22 are made of high-temperature resistant conductive materials, and the first connection portion 21 and the plurality of first connection units 22 are in electrical contact; the inner side walls of the plurality of first connection units 22 and the plurality of second connection units 23 of one embedded component 2 are smoothly transitioned with the inner side wall of the tube body 1, and the inner side walls of the plurality of first connection units 22 and the plurality of second connection units 23 of the other embedded component 2 are also smoothly transitioned with the inner side wall of the tube body 1, thereby restoring the flow guide hole 12 arranged coaxially with the flow guide tube. In addition, the two embedded components 2 are respectively adaptively installed in the two grooves 11. Here, the adaptation specifically means that the plurality of first connection units 22 and the plurality of second connection units 23 are arranged at intervals in sequence along the axis of the tube body 1, and the contact surfaces are adaptively fitted without gaps. In addition, the electrical contact formed between the first connection portion 21 and the plurality of first connection units 22 can also be understood as that the first connection portion 21 and the plurality of first connection units 22 are adaptively fitted without gaps, and at the open end, the top surface of the embedded component 2 is smoothly transitioned with the end face of the open end of the tube body 1.

[0030] The two output electrodes of the current generating unit 4 are respectively electrically connected to the two first connection portions 21; the magnetic field generating unit 5 is used to generate a magnetic field that completely covers or partially covers the area of the flow guide hole 12; wherein, the current direction, the magnetic field direction, and the axis of the flow guide tube are perpendicular to each other in pairs, so that when there is molten metal flowing along the axis of the flow guide tube in the flow guide tube, the molten metal generates a Lorentz force distributed along the axis of the flow guide tube, and the current direction and magnitude and / or the magnetic field direction and magnitude are adjustable. An external electrode 3 located outside the tube body 1 is installed on the first connection portion 21. The electrical connection between the current generating unit 4 and the two first connection portions 21 can be realized by respectively electrically connecting the two output electrodes of the current generating unit 4 to the two external electrodes 3.

[0031] When the first connecting portion 21 and multiple first connecting units 22 are integrally formed, the second connecting unit 23 can first install the embedded component 2 by laterally embedding it into adjacent two sets of first connecting units 22 in a one-to-one correspondence manner, and then integrally embed the embedded component 2 into the groove body 11. When multiple second connecting units 23 are made of high-temperature resistant conductive materials, and multiple second connecting units 23, multiple first connecting units 22, and the first connecting portion 21 are integrally formed, directly integrally embedding the embedded component 2 into the groove body 11 can achieve the goal.

[0032] In addition, the embedded component 2 can also be fixed in the groove body 11 by means of bonding, clamping, welding, etc.

[0033] The first connecting portion 21 and multiple first connecting units 22 are specifically made of high-purity high-strength graphite with low resistivity. This material has an extremely high melting point. It should be noted that when this material is used, it is only for the preparation of metal powders that will not have carbon element penetration into the molten metal.

[0034] The pipe body 1 can be made of high-temperature resistant ceramic materials.

[0035] It should be noted that although the molten metal flowing through the diversion pipe is an interconnected whole, it seems that as long as the molten metal flowing through the entire diversion pipe is energized, current can be generated, and the molten metal can self-heat and keep warm to prevent blockage of the package, and the downward Lorentz force can be generated by the molten metal to further prevent blockage of the package.

[0036] However, the inventor found in actual research that the resistivity of the vast majority of molten metals is significantly greater than that of the relevant components in the circuit, making the molten metal in the entire circuit the main heating body. As disclosed in D1, when connecting the molten metal through two electrodes, only the molten metal flowing through the shortest path between the two electrodes generates current, self-heats, and generates Lorentz force. And since the molten metal is still flowing, local stress is extremely likely to cause turbulence. Moreover, due to the small cross-sectional area of the molten metal flowing through the shortest path between the two electrodes and the relatively large resistivity of the molten metal itself, the resistance of the self-heating molten metal is extremely large. Therefore, when the current remains unchanged, the self-heating of the molten metal is extremely serious, making D1 unable to be realized.

[0037] In the solution proposed in Embodiment 1, in the axial direction of the tube body 1, there are multiple first connection units 22 and multiple second connection units 23, and both the multiple first connection units 22 and the multiple second connection units 23 are in contact with the first connection portion 21. When the multiple first electrical connection units 22 are conductive, and if the multiple second connection units 23 are made of a non-conductive high-temperature resistant material, a loop is formed between two first connection units 22 at the same height relative to the axial direction of the tube body 1 in the two embedded components 2 and the molten metal flowing through the shortest path between the two first connection units 22, and current can be generated between them. It should be noted that for the embedded component 2, there are multiple first connection units 22, that is to say, multiple loops will be formed. It should be further pointed out that since the two embedded components are the same and are symmetrically arranged relative to the axial direction of the tube body 1, the lengths of the shortest paths between a set of first connection units 22 corresponding to the multiple loops are equal. That is to say, current will be generated in multiple loops, and the multiple loops are in parallel, which can be equivalent to the cross-sections of multiple resistors being superimposed, and the resistance of the heated molten metal can be reduced several times. Based on this, a suitable Lorentz force can be applied to the molten metal, and the heat generated by the large current flowing through the molten metal can be greatly reduced, thus solving the consequences caused by excessive self-heating of the molten metal mentioned in the background art. In Embodiment 1, the axial length, quantity, and width of the first connection unit 22 can be adjusted according to the actual current magnitude and the self-heating situation of the molten metal.

[0038] Embodiment 1 also proposes an extreme case:

[0039] The first connection portion 21 and the multiple first connection units 22 are integrally formed, the multiple second connection units 23 are all made of high-temperature resistant conductive materials, and the multiple second connection units 23, the multiple first connection units 22, and the first connection portion 21 are integrally formed. Based on the above technical features, the two embedded components 2 are both an integrally formed whole and are respectively adaptively installed in two slots 11 that are symmetrically arranged relative to the axis of the tube body 1. It can be deduced that the two embedded components 2 are arranged in parallel, and the conductor parts exposed in the diversion holes 12 are also arranged in parallel. The molten metal flowing between the two embedded components 2 has continuity in the axial direction of the tube body 1, and current will be generated in all of them, maximizing the cross-sectional area of the self-heating molten metal and minimizing the resistance, and the problem of serious self-heating can be controlled. In addition, the molten metal flowing through the diversion holes 12 will be subject to the Lorentz force as a whole, and the turbulence caused by the Lorentz force can be avoided as much as possible.

[0040] Embodiment 2

[0041] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5Embodiment 2 proposes an atomizer flow guide tube, comprising a tube body 1 with a flow guide hole 12, and two embedded components 2. Two grooves 11 are arranged symmetrically relative to the axial direction of the tube body 1 on the inner wall of the tube body 1. The two grooves 11 penetrate one end wall of the tube body 1 and form openings on the end wall. The two embedded components 2 are respectively embedded in the two grooves 11 through the two openings and restore the flow guide hole 12. The embedded component 2 specifically includes a first connecting portion 21 and a second connecting portion. The first connecting portion 21 and the second connecting portion are both extended from the bottom of the groove body 11 to the opening side and are arranged in sequence along the axial direction of the tube body 1. The first connecting portion 21 is close to the outer wall of the tube body 1. The second connecting portion specifically includes a plurality of first connecting units 22 and a plurality of second connecting units 23. The plurality of first connecting units 22 and the plurality of second connecting units 23 are arranged in sequence in the axial direction of the tube body 1. The first connecting portion 21 and the plurality of first connecting units 22 are both made of high temperature resistant conductive material, and the first connecting portion 21 and the plurality of first connecting units 22 are in electrical contact. The first connection part 21 is provided with an external electrode 3 outside the tube body 1. The first connection part 21 and the plurality of first connection units 22 are integrally formed. The plurality of second connection units 23 are made of high temperature resistant conductive material, and the plurality of second connection units 23, the plurality of first connection units 22 and the first connection part 21 are integrally formed.

[0042] The flow guide tube can be applied to the atomizer flow guide tube assembly proposed in Example 1. The specific structure and working principle have been described in detail in Example 1 and will not be repeated here.

[0043] Example 3

[0044] Embodiment 3 proposes an atomizer equipped with an atomizer flow guide tube or an atomizer flow guide tube assembly, and the flow guide tube is arranged vertically, and also includes a high-pressure gas generating unit, and the high-pressure gas outlet of the high-pressure gas generating unit is highly coupled with the flow guide tube outlet in terms of geometric position.

[0045] Example 4

[0046] In the process of preparing powder by vacuum air atomization in the prior art, especially some new alloy powders containing high aluminum content or high titanium content, the raw alloy becomes very viscous and dissipates heat very quickly after being melted into molten metal, which easily blocks the tundish or liquid guide tube, resulting in tundish blockage. It is difficult to obtain alloy powder products with a fine powder yield that meets the standard by the existing vacuum air atomization method.

[0047] An atomizer including an atomizer guide tube assembly proposed in Example 1 or Example 2 is proposed, wherein the tube body 1 is made of boron nitride ceramic material, the first connecting part 21 uses metal tungsten as the conductive material, the first connecting unit 22 is made of high-purity and high-strength graphite material, and the diameter of the guide hole 12 is designed to be 6 mm.

[0048] Taking the atomizer proposed in Embodiment 4 as an example, a high-entropy alloy powder FeCrNiCoAl0.2Ti0.3 containing Al and Ti is prepared by the following process.

[0049] The first step is to assemble raw materials; according to the alloy atomic ratio Fe:Cr:Ni:Co:Al:Ti = 1:1:1:1:0.2:0.3, raw materials are configured, and the raw materials are put into the intermediate-frequency induction crucible of the vacuum induction furnace and heated into molten metal.

[0050] In the second step, the molten metal flows downward through the liquid guide tube. The current generated by the current generating unit 4 will form a parallel circuit between multiple groups of first connection units 22, and self-heating insulation will be formed for the molten metal between each parallel circuit, which can effectively neutralize the excessive heat loss of the aluminum-containing alloy, prevent clogging of the package. At the same time, since multiple circuits are in parallel, it is equivalent to the cross-sections of multiple resistors being superimposed, which can reduce the resistance of the heated molten metal several times, thereby effectively preventing overheating. At the same time, in the extreme case, when both the first connection unit 22 and the second connection unit 23 are made of tungsten metal conductive materials, the heat generation can be minimized. At the same time, the downward Lorentz force generated acts on all the molten metal in the liquid guide tube. Since the molten metal has consistency and the liquid guide tube has consistency, the Lorentz force also has consistency, thereby effectively preventing turbulence.

[0051] According to the actual situation, the Lorentz force can also be adjusted by adjusting the current magnitude and the magnetic field magnitude.

[0052] In the third step, both the flow rate and the flow volume of the high-pressure gas can be controlled by the high-pressure gas generation control unit, and the high-pressure gas outlet of the high-pressure gas generation unit is highly coupled with the outlet of the diversion tube in terms of geometric position, so as to impact the molten metal flowing out of the liquid guide tube with high-pressure gas and then fall to form metal powder.

[0053] The results show that clogging of the package did not occur, and after screening and sorting the obtained powder, it is shown that the yield of fine powder has been greatly improved.

[0054] Embodiment 5

[0055] In the prior art, in the process of preparing CuAl10 alloy powder by vacuum gas atomization method, due to the presence of Al in the raw materials, the viscosity of the molten metal composed of this alloy is very high, and during the movement of the molten metal in the diversion tube, the heat diffusion speed is fast, making the diversion tube extremely prone to clogging.

[0056] A nebulizer incorporating a nebulizer duct assembly as proposed in Embodiment 1 or Embodiment 2 is presented. Among them, the tube body 1 is made of boron nitride ceramic material, the first connection part 21 uses tungsten metal as the conductive material, the first connection unit 22 is made of high-purity and high-strength graphite material, the diameter of the diversion hole 12 is designed to be 5 mm, and both the first connection part 21 and the first connection unit 22 are made of high-purity and high-strength graphite material with low resistivity.

[0057] Using the nebulizer proposed in this Embodiment 5, the CuAl10 alloy powder is prepared through the following process.

[0058] The first step is to assemble raw materials; according to the mass ratio of Al: 9.5 - 10.5% and the balance of Cu, the raw materials are configured, and the raw materials are placed in the intermediate-frequency induction crucible of a vacuum induction furnace and heated into molten metal.

[0059] The second step is that the molten metal flows downward through the liquid guide tube. The current generated by the current generating unit 4 will form a parallel circuit between multiple groups of the first connection units 22, and self-heating insulation will be formed for the molten metal between each parallel circuit, which can effectively neutralize the excessive heat loss of the aluminum-containing alloy and prevent blockage of the package. At the same time, since multiple circuits are in parallel, it is equivalent to the cross-sections of multiple resistors being superimposed, which can reduce the resistance of the heated molten metal by several times, thereby effectively preventing overheating. At the same time, in the extreme case, when both the first connection unit 22 and the second connection unit 23 are made of tungsten metal as the conductive material, the heat generation can be minimized. At the same time, the downward Lorentz force generated acts on all the molten metal in the liquid guide tube. Since the molten metal has uniformity and the liquid guide tube has uniformity, the Lorentz force also has uniformity, thereby effectively preventing turbulence.

[0060] According to the actual situation, the Lorentz force can also be adjusted by adjusting the magnitude of the current and the magnitude of the magnetic field.

[0061] The third step is that the flow rate and flow volume of the high-pressure gas can both be controlled by the high-pressure gas generation control unit, and the high-pressure gas outlet of the high-pressure gas generation unit is highly coupled with the outlet of the diversion tube in terms of geometric position, so as to impact the molten metal flowing out of the liquid guide tube with high-pressure gas and then fall to form metal powder.

[0062] The results show that blockage of the package did not occur, and after screening and sorting the obtained powder, it shows that the yield of fine powder has been greatly improved.

[0063] As mentioned above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
