Description

Technical Field

[0001] This utility model relates to the field of electroslag remelting technology, and more specifically, to a high-temperature alloy electroslag remelting device. Background Technology

[0002] Electroslag remelting is a special smelting process that uses the resistance heat of molten slag for secondary refining. It can effectively remove impurities, gases and inclusions from metals, and improve the crystal structure and mechanical properties of metals. It is especially important for the preparation of high-end materials such as high-temperature alloys and special steels.

[0003] In the prior art, such as Chinese Patent No. CN221588639U, an electroslag remelting furnace and electroslag remelting equipment are disclosed. This document describes a cooling water flow chamber located inside the side wall of the crystallizer. Cooling water flows in from the bottom, circulates within the chamber, and then flows out from the other end, thereby removing heat generated during the crystallization process. However, this device uses a single cooling water flow chamber with a large volume. When the cooling water flows within the chamber, it easily leads to uneven water distribution, with high cooling intensity in areas closer to the inlet and weaker cooling in areas farther from the inlet, resulting in uneven circumferential and axial cooling of the crystallizer. Utility Model Content

[0004] This invention provides a high-temperature alloy electroslag remelting device that ensures consistent water flow in each channel and enables rapid circulation of cooling water, avoiding flow differences caused by varying water path lengths and solving the problem of uneven water distribution in traditional devices.

[0005] To achieve the above objectives, this utility model proposes a high-temperature alloy electroslag remelting device, comprising a furnace, a water inlet assembly, and a drainage assembly. Multiple heat dissipation channels are equally spaced along the axial direction within the furnace shell. These channels extend circumferentially along the furnace. Each heat dissipation channel has a water inlet at one end and a water outlet at the other end, extending to the outer wall of the furnace. The water inlet assembly is connected to the multiple water inlets and injects cooling water into the multiple heat dissipation channels through these inlets. The drainage assembly is connected to the multiple water outlets and discharges the cooling water from the multiple heat dissipation channels through these outlets.

[0006] Preferably, the furnace has a furnace cavity at the top, and the heat dissipation channels are distributed around the outer periphery of the furnace cavity.

[0007] Preferably, an ingot is fixedly connected to the inner wall of the furnace cavity, and a molten metal pool is formed on the top of the ingot.

[0008] Preferably, a lifting mechanism is installed above the furnace, and an electrode is fixedly connected to the output end of the lifting mechanism. The lifting mechanism is used to drive the electrode to move vertically.

[0009] Preferably, it also includes a mounting base, the top of which is fixedly connected to the bottom of the furnace.

[0010] Preferably, the water inlet assembly includes multiple water inlet tanks and water injection pipes. The water inlet tanks are fixedly connected to the outer wall of the furnace and communicate with the water inlet. The water injection pipes are fixedly connected to the multiple water inlet tanks.

[0011] Preferably, the drainage assembly further includes multiple drainage channels and drainage pipes. The drainage channels are fixedly connected to the outer wall of the furnace and communicate with the water outlet. The drainage pipes are fixedly connected to the multiple drainage channels.

[0012] Preferably, the outer wall of the water injection pipe and the drain pipe is provided with multiple water distribution pipes, and the water injection pipe and the drain pipe are respectively connected to the corresponding water inlet tank and the drain tank through the water distribution pipes.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By employing multiple axially spaced heat dissipation channels, each extending circumferentially along the furnace, a single, large flow cavity is replaced, achieving uniform coverage of the cooling area, avoiding localized cooling blind spots, and ensuring cooling uniformity. The water inlet assembly is connected to multiple water inlets, allowing cooling water to be injected into all heat dissipation channels simultaneously, ensuring consistent water flow in each channel, and enabling rapid circulation of cooling water. This avoids flow differences caused by varying water path lengths, solving the problem of uneven water distribution in traditional devices.

[0015] 2. The heat dissipation channels are distributed around the outer perimeter of the furnace cavity, which can directly cool the areas with concentrated heat, improve heat transfer efficiency, and the surrounding layout can ensure more even cooling around the furnace cavity, avoiding local overheating or insufficient cooling.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a high-temperature alloy electroslag remelting device includes a furnace 2, a water inlet assembly, and a drainage assembly. Multiple heat dissipation channels 6 are equally spaced along the axial direction inside the furnace 2 shell. The heat dissipation channels 6 extend circumferentially along the furnace 2. Each heat dissipation channel 6 is independent and not interconnected. One end of each heat dissipation channel 6 has a water inlet 8, and the other end has a water outlet 7. The water outlet 7 and the water inlet 8 extend to the outer wall of the furnace 2. The water inlet assembly is connected to the multiple water inlets 8 and injects cooling water into the multiple heat dissipation channels 6 through the water inlets 8. The drainage assembly is connected to the multiple water outlets 7 and discharges the cooling water from the multiple heat dissipation channels 6 through the water outlets 7.

[0022] Multiple axially spaced heat dissipation channels 6 are arranged circumferentially to ensure that cooling water can evenly cover the furnace shell 2, avoiding local differences in cooling intensity. The water inlet assembly is connected to multiple water inlets 8 to achieve synchronous distribution of cooling water, making the water flow in each channel more uniform and rapid, the cooling more stable, and improving the circumferential and axial cooling uniformity of the furnace 2.

[0023] like Figure 2 As shown, the furnace 2 has a furnace cavity 3 on the top, and heat dissipation channels 6 are distributed around the furnace cavity 3. They can directly cool the heat concentration area, improve the heat transfer efficiency, and the surrounding layout can ensure that the cooling around the furnace cavity 3 is more balanced, avoiding local overheating or insufficient cooling.

[0024] like Figure 2 As shown, an ingot 4 is fixedly connected to the inner wall of the furnace cavity 3. The ingot 4 is made of graphite material. A molten metal pool 5 is opened on the top of the ingot 4. The molten metal pool 5 is used to contain high-temperature alloy raw materials and slag.

[0025] like Figure 1 As shown, a lifting mechanism 15 is installed above the furnace 2. An electrode 14 is fixedly connected to the output end of the lifting mechanism 15. The lifting mechanism 15 is used to drive the electrode 14 to move vertically and adjust the distance between the electrode 14 and the molten metal pool 5.

[0026] The lifting mechanism 15 is an electric lifting platform, and its output end is fixedly connected to the electrode 14 via a flange.

[0027] like Figure 1As shown, the remelting device also includes a mounting base 1, the top of which is fixedly connected to the bottom of the furnace 2. The mounting base 1 is made of cast iron and has an anti-slip pad on the bottom to enhance the stability of the device.

[0028] like Figures 1-3 As shown, the water inlet assembly includes multiple water inlet tanks 9 and water injection pipes 10. The water inlet tanks 9 are fixedly connected to the outer wall of the furnace 2 and are connected to the water inlet 8. The water injection pipes 10 are fixedly connected to the multiple water inlet tanks 9. The drainage assembly also includes multiple drainage tanks 11 and drainage pipes 12. The drainage tanks 11 are fixedly connected to the outer wall of the furnace 2 and are connected to the water outlet 7. The drainage pipes 12 are fixedly connected to the multiple drainage tanks 11. The outer walls of the water injection pipes 10 and the drainage pipes 12 are provided with multiple water distribution pipes 13. The water injection pipes 10 and the drainage pipes 12 are connected to the corresponding water inlet tanks 9 and drainage tanks 11 through the water distribution pipes 13.

[0029] The furnace 2 is fixed on top of the mounting base 1, ensuring that the ingot 4 is securely installed on the inner wall of the furnace chamber 3, and the molten metal pool 5 is located on top of the ingot 4. The height of the electrode 14 is adjusted by the lifting mechanism 15 so that the lower end of the electrode 14 extends into the molten metal pool 5, completing the preparation work before electroslag remelting.

[0030] The implementation principle of this application is as follows: when starting, the cooling water flows into each branch pipe 13 through the water injection pipe 10, and then into the corresponding heat dissipation channel 6 through the water inlet 9 and the water inlet 8. The cooling water flows in the heat dissipation channel 6 that extends around the furnace 2, absorbs the heat of the furnace cavity 3, and then quickly flows out from the water outlet 7 to the drain trough 11. Finally, it is discharged through the branch pipe 13 and the drain pipe 12, so as to realize the rapid circulation of cooling water.

[0031] When the power supply to electrode 14 is turned on, the lifting mechanism 15 drives electrode 14 to move vertically to a suitable position. Electrode 14 generates an electric arc with the slag in the molten metal pool 5, causing the high-temperature alloy raw material in the molten metal pool 5 to melt. During the melting process, the cooling water in the heat dissipation channel 6 continuously removes heat and controls the temperature of the furnace cavity 3.

[0032] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
