Currently, arc melting is widely used in research institutions and laboratories. Most current arc melting furnaces are used in laboratories to melt various metal alloys. After melting, the sample needs to be removed and sent to a diffractometer for in-situ optical measurements and particle scattering measurements.

[0003] This experimental method has a low degree of automation and cannot perform multi-station material melting. For scenarios requiring vacuum melting, frequent vacuuming is required, resulting in very low melting efficiency. Summary of the Invention

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figure 1-4A multi-station automated electric arc furnace includes a base 1, with multiple casters 11 below the base 1, a worktable 2 on the base 1, a vacuum hood 4 on the worktable 2, a sample tray 3 inside the vacuum hood 4, and multiple placement slots on the sample tray 3; multiple samples are placed through the placement slots.

[0032] The workbench 2 is equipped with a sealing ring 23 corresponding to the vacuum hood 4. The workbench 2 also has a mounting rack 21 for installing the sample tray 3. The vacuum hood 4 contains a clamping mechanism 8 for moving materials, and a turning mechanism 9 for flipping materials on one side. The side wall of the vacuum hood 4 has an extraction port 41 connected to a vacuum pump, which can be a vacuum pump. The base 1 has a lifting mechanism for raising the vacuum hood 4. The lifting mechanism facilitates the placement and removal of samples by raising and lowering the vacuum hood 4. The clamping mechanism 8 clamps and moves the materials, and the turning mechanism 9 flips the materials to ensure complete melting.

[0033] Both the workbench 2 and the sample tray 3 are provided with a clearance opening 31 in the middle. A sample tray 222 is provided in the clearance opening 31. A lifting mechanism is provided at the lower end of the sample tray 222 to drive the sample tray 222 to rise and fall. The clearance opening 31 facilitates the lifting mechanism to drive the sample tray 222 to rise and fall, so that the sample tray 222 can be lifted and sent into the melting furnace 6 for melting.

[0034] A smelting furnace 6 is vertically mounted on the upper end of the vacuum hood 4. The feed inlet at the lower end of the smelting furnace 6 is connected to the upper end of the vacuum hood 4, facilitating the feeding of the sample tray 222 into the smelting furnace 6. A hoisting mechanism 7 is provided above the vacuum hood 4 for lifting. The hoisting mechanism 7 facilitates the overall movement of the equipment.

[0035] Based on the above technical solution, when metal smelting is required, the metal material to be smelted is placed in the placement slot of the sample tray 3. The lifting mechanism is activated to lower the vacuum chamber 4, which, in conjunction with the sealing ring 23, achieves a sealed state within the vacuum chamber 4. After sealing, the vacuum pump is activated to evacuate the vacuum chamber 4, ensuring a vacuum atmosphere during metal smelting. During smelting, the clamping mechanism 8 is activated to clamp the sample from the sample tray 3 and place it on the sample tray 222. The lifting mechanism is activated to raise the sample tray 222 and send it into the smelting furnace 6. The smelting furnace 6 is then activated for smelting. After smelting, the sample tray 222 is reset. The flipping mechanism 9 is activated to flip the material, and the lifting mechanism is activated again to send the material into the smelting furnace 6 for smelting. After smelting, the sample tray 222 is reset again, and the clamping mechanism 8 clamps the smelted material from the sample tray 222 back into the placement slot, allowing for the next smelting operation. After completing multi-station smelting, the material can be removed for in-situ optical measurements and particle scattering measurements. This significantly improves the efficiency of smelting multiple metal samples.

[0036] In this technical solution, such as Figure 1-3 As shown, an observation window 42 is provided on the side wall of the vacuum chamber 4, and a camera 421 is correspondingly provided on the outside of the observation window 42. The camera 421 facilitates visual recognition, thereby improving the accuracy of sample clamping and ensuring stable sample clamping.

[0037] In this technical solution, such as Figure 1-4 As shown, the melting furnace 6 includes a furnace cavity 61 and an electric arc melting lance 62 disposed above the furnace cavity 61. The furnace cavity 61 is made of transparent quartz material. A cooling ring 63 is provided on the lower part of the side wall of the furnace cavity 61, and cooling water flows through the cooling channel in the cooling ring 63. The material is melted by the electric arc melting lance 62. The quartz furnace cavity 61 facilitates the observation of the material during melting. The cooling ring 63 is used to cool the molten metal material. The quartz furnace cavity 61 also facilitates in-situ optical measurement and particle scattering measurement of the molten metal by directly using a diffractometer. Specifically, after all the metal material is melted, the entire equipment is hoisted to the diffractometer by the hoisting mechanism 7, the material is then sent to the sample tray 222 by the clamping mechanism 8, and then sent to the furnace cavity 61 by the lifting mechanism. In-situ optical measurement and particle scattering measurement are performed using the diffractometer, and multiple metal samples are measured sequentially.

[0038] In this technical solution, such as Figure 1-3 As shown, the clamping mechanism 8 includes a first linear motor 81 mounted on both sides of the sample tray 3 on the worktable 2. Each first linear motor 81 has a first slide block 811, and each slide block 811 has a vertically mounted mounting bracket 82. A second linear motor 83 is horizontally mounted between the mounting brackets 81, and each second linear motor 83 has a second slide block 831. A clamping jaw 84 is vertically mounted on the second slide block 831. The clamping jaw 84 can be either an electric clamping jaw or an actuated clamping jaw. By having the two first linear motors 81 drive the clamping jaw 84 to move in the X-axis direction, and the second linear motor 83 drives the clamping jaw 84 to move in the Y-axis direction, the clamping jaw 84 can move horizontally, facilitating the clamping of materials on the sample tray 222.

[0039] In this technical solution, such as Figure 1-3As shown, the material turning mechanism 9 includes a third linear motor 91 horizontally fixed to the side wall of the vacuum chamber 4 via a bracket, a third slide block 911 slidably mounted on the third linear motor 91, a vertically mounted mounting plate 92 on the third slide block 911, and a material turning gripper 93 horizontally mounted on the mounting plate 92. The material turning gripper 93 extends into the vacuum chamber 4 and can clamp and turn the material. A sealing sleeve 931 is fitted on the outside of the material turning gripper 93. The material turning gripper 93 can be an electric gripper or a pneumatic gripper. The third linear motor 91 drives the material turning gripper 93 to move in the radial direction of the sample tray 3, so as to move the material turning gripper 93 to the sample tray 222 to turn the material. The sealing sleeve 931 can be a bellows seal to ensure the sealing effect in the vacuum chamber 4 while the third slide block 911 slides.

[0040] In this technical solution, such as Figure 1-3 As shown, the lifting mechanism includes multiple second cylinders 5 vertically mounted on the base 1, and multiple ear plates fixedly connected to the telescopic ends of the second cylinders 5 on the side wall of the vacuum chamber 4. The lifting and lowering of the vacuum chamber 4 is controlled by the second cylinders 5 to facilitate the placement and retrieval of samples.

[0041] In this technical solution, such as Figure 1-3 As shown, multiple stabilizing rods 51 are vertically mounted on the base 1, and each stabilizing rod 51 is slidably fitted with a sliding sleeve 44, which is fixedly installed on the side wall of the vacuum chamber 4. The design of the stabilizing rods 51 and the sliding sleeves 44 facilitates the stable raising and lowering of the vacuum chamber 4, ensures the contact effect between the vacuum chamber 4 and the sealing ring 23, and guarantees the sealing effect of the vacuum chamber 4.

[0042] In this technical solution, such as Figure 1-3 As shown, the lifting mechanism includes a first cylinder 22 located below the workbench 2 for lifting the sample tray 222. A sealing cover 221, which is sealed to the lower surface of the workbench 2, is provided on the outside of the first cylinder 22. The lifting of the sample tray 222 is controlled by the first cylinder 22 to facilitate the feeding of materials into the melting furnace 6 for melting. The sealing cover 221 ensures the sealing effect of the sealing cover 4.

[0043] In this technical solution, such as Figure 1-3 As shown, the hoisting mechanism 7 includes a top plate 71 above the melting furnace 6, with multiple connecting columns 72 connecting the top plate 71 to the vacuum hood 4, and multiple hoisting rings 73 on the top plate 71. The hoisting rings 73 facilitate the overall hoisting of the equipment, so that the equipment can be sent into the diffractometer for sample measurement.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
