[0002] A vacuum melting furnace is a device used to melt materials and prepare alloys at high temperatures. Its main feature is that it can operate under low pressure or vacuum conditions to prevent oxidation reactions or other gases from reacting adversely with alloy materials during the melting process. This type of equipment is often used in industry and scientific research to produce high-quality nickel-based alloys.

[0003] In the vacuum melting furnace disclosed in the publication number CN206772001U, although the utility model realizes the automatic flipping of the crucible by the cooperation of the hydraulic cylinder and the main shaft, it not only solves the problem of inconvenient manual operation, but also uses the channel inside the main shaft to isolate the power line of the heating component inside, thereby preventing the driving mechanism such as the hydraulic cylinder from being affected by high temperature and achieving good sealing.

[0004] However, the vacuum melting furnace has the following disadvantages:

[0005] (1) The vacuum melting furnace is not convenient for fully mixing the raw materials by stirring, which reduces the production quality of the alloy;

[0006] (2) The vacuum melting furnace is not convenient for adding raw materials into the melting furnace or removing finished products through the magnetic attraction structure, which reduces the convenience of using the vacuum melting furnace. Utility Model Content

[0013] Through the above technical solution and the setting of the electromagnet, the purpose of magnetically attracting raw materials or finished products is achieved.

[0014] As a further improvement of the above solution, an observation tube is connected through one side of the top of the round cover close to the cylinder, and an observation mirror is fixedly connected inside the observation tube.

[0015] Through the above technical solution, by providing the observation mirror, the user can observe the smelting conditions inside the smelting furnace body through the observation mirror.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model is provided with a stirring component. When the user uses the smelting furnace, the user adds raw materials into the smelting furnace body through the adding component, connects the servo motor to the external power supply, rotates the transmission rod to drive the stirring rod to stir the raw materials in the smelting furnace body, and fully mixes the raw materials. When the smelting is completed, the stirring rod stops rotating when the servo motor is powered off, so that the vacuum smelting furnace can fully mix the raw materials through stirring, thereby improving the production quality of the alloy.

[0022] The utility model provides an adding component. When the user uses the smelting furnace, the user energizes the electromagnet and the external power supply to generate magnetic force. Then the user can add metal raw materials to the bottom of the electromagnet through the insertion slot.

Then the user observes the position of the metal raw materials through the observation mirror. When the metal raw materials are located at a suitable position, the user disconnects the power supply of the electromagnet to make the metal raw materials fall into the smelting furnace body. Finally, the user controls the electric push rod to retract and stop when the closing plate is located in the cylinder near the round cover, providing a sealed environment for the smelting furnace body. After the reaction is completed, the user can again take away the finished product inside the smelting furnace body through the electric push rod and the electromagnet, so that the vacuum smelting furnace can add raw materials or take away the finished product inside the smelting furnace through the magnetic attraction structure, thereby improving the convenience of using the vacuum smelting furnace.

When the melting is completed, the stirring rod 203 stops rotating when the servo motor 202 is powered off, so that the vacuum melting furnace can fully mix the raw materials by stirring, thereby improving the efficiency of the melting furnace. In order to improve the production quality of the alloy, a round cover 3 is overlapped on the top of the smelting furnace body 1, and an opening is opened in the middle of the top of the round cover 3, and a cylinder 4 is sleeved inside the opening. An adding component 5 is fixedly connected to the top of the cylinder 4. By setting the adding component 5, when the user uses the smelting furnace, the electromagnet 502 is energized with an external power supply to make the electromagnet 502 generate magnetic force, and then the user can add metal raw materials to the bottom of the electromagnet 502 by inserting the slot 11. When the metal raw materials are magnetically attracted by the electromagnet 502, the user connects the electric push rod 501 to the external power supply so that the electric push rod 501 drives the electromagnet 502 to descend, and then the user observes the position of the metal raw materials through the observation mirror 7. When the metal raw material is at a suitable position, the user disconnects the power supply of the electromagnet 502, so that the metal raw material falls into the smelting furnace body 1. Finally, the user controls the electric push rod 501 to recycle and stop when the closing plate 503 is located in the cylinder 4 near the round cover 3, providing a sealed environment for the smelting furnace body 1. After the reaction is completed, the user can use the electric push rod 501 and the electromagnet 502 to take out the finished product inside the smelting furnace body 1 again, so that the vacuum smelting furnace can add raw materials to the inside of the smelting furnace or take out the finished product through the magnetic attraction structure, which improves the convenience of using the vacuum smelting furnace. Insertion grooves 11 are provided on both sides of the cylinder 4. Through the setting of the insertion grooves 11, the purpose of facilitating the addition of metal raw materials to the bottom of the electromagnet 502 is achieved;

The arrangement of the lower connecting flange 8 and the upper connecting flange 9 achieves the purpose of facilitating the removal of the round cover 3;

[0037] The bottom of the lower connecting flange 8 is fixedly connected to a shell 10, and the surface of the shell 10 is fixedly connected to a servo motor 202.

[0038] The implementation principle of a vacuum melting furnace for melting nickel-based alloys in the embodiment of the present application is as follows: when using the melting furnace, the user energizes the electromagnet 502 and the external power supply to make the electromagnet 502 generate magnetic force, and then the user can add metal raw materials to the bottom of the electromagnet 502 through the insertion slot 11. When the metal raw materials are magnetically attracted by the electromagnet 502, the user connects the electric push rod 501 to the external power supply so that the electric push rod 501 drives the electromagnet 502 to descend, and then the user observes the position of the metal raw materials through the observation mirror 7. When the metal raw material is in a suitable position, the user disconnects the power supply of the electromagnet 502 to make the metal raw material fall into the smelting furnace body 1. Finally, the user controls the electric push rod 501 to retract and stop when the closing plate 503 is located in the cylinder 4 near the round cover 3, providing a sealed environment for the smelting furnace body 1. After turning on the smelting furnace, the user connects the servo motor 202 to an external power supply and rotates the transmission rod 201 to drive the stirring rod 203 to stir the raw materials inside the smelting furnace body 1. After the reaction is completed, the user can use the electric push rod 501 and the electromagnet 502 again to take out the finished product inside the smelting furnace body 1.
