[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0021] Referring to Figs. 1-2 A rapid melting device for recycling of recycled steel materials mainly comprises a support 1, a high-frequency induction furnace 2 and a loading and unloading mechanism. The support 1 serves as the basic support structure of the entire device, ensuring the stability and durability of the device. The high-frequency induction furnace 2 is vertically installed on the support 1 and is the core melting component of the device, responsible for rapidly heating the steel material to a molten state. The loading and unloading mechanism is installed on the support 1 below the high-frequency induction furnace 2 and is used to cooperate with the high-frequency induction furnace 2 to take and place the steel material.

[0022] Specifically:

[0023] The high-frequency induction furnace 2 is designed uniquely, with both the upper and lower furnace openings being open, facilitating the rapid taking and placing of the steel material. The furnace body, as the carrier of the high-frequency induction coil 8, is made of high-temperature-resistant and corrosion-resistant materials to ensure stable operation in a long-term high-temperature environment. The high-frequency induction coil 8 is installed in the furnace body through an insulating support 1, and a high-frequency control power supply 9 for cooperating with the high-frequency induction coil 8 is also installed on the support 1. When the high-frequency control power supply 9 provides high-frequency alternating current to the coil, a strong alternating magnetic field will be generated around the coil, which in turn generates eddy currents in the steel material placed therein, achieving rapid heating and melting of the steel material.

[0024] The loading and unloading mechanism is a bridge connecting the high-frequency induction furnace 2 and the steel material, and its design fully considers the convenience and efficiency of operation, mainly including a lifting mechanism and a translation mechanism. The lifting mechanism includes a furnace base 4 for cooperating with the lower furnace opening of the high-frequency induction furnace 2 and a lifting driving device 5 for driving the vertical lifting action of the furnace base 4. A smelting crucible 3 for storing steel materials is also installed on the furnace base 4, which facilitates the vertical lifting of the smelting crucible 3 and the steel materials therein to the lower furnace opening of the high-frequency induction furnace 2. The furnace base 4, as the load-bearing component of the lifting mechanism, is closely matched with the lower furnace opening of the high-frequency induction furnace 2, ensuring the stability of the steel materials during the smelting process. Preferably, the furnace base 4 and the high-frequency induction furnace 2 at the lower furnace opening are both arranged in a stepped manner. The lifting driving device 5 uses a lifting driving cylinder to control the lifting action of the furnace base 4, which has the advantages of fast response speed and high control precision. A positioning groove is also provided on the top of the furnace base 4 for cooperating with the positioning protruding column 10 at the bottom of the smelting crucible 3, further enhancing the stability of the smelting crucible 3 during the lifting process.

[0025] The translation mechanism is responsible for moving the lifting mechanism and the smelting crucible 3 to the designated position along the horizontal direction. Specifically, it includes a translation base 6 and a translation driving device 7 for driving the horizontal movement of the translation base 6. The lifting driving device 5 is vertically fixedly installed on the translation base 6, and the furnace base 4 is transversely fixedly installed on the driving end of the lifting driving device 5. The translation driving device 7 also uses a translation driving cylinder to control the horizontal movement of the translation base 6. A sliding block 11 is also installed on the translation base 6, and a slide groove is provided on the support 1 to cooperate with the sliding block 11. The sliding block 11 is slidingly installed in the slide groove. This design not only enhances the stability of the translation mechanism, but also reduces the frictional resistance during movement, improving the efficiency of movement.

[0026] In actual use, in order to ensure the accuracy of the movement of the translation base 6 and ensure that the furnace base 4 can accurately butt joint with the lower furnace opening of the high-frequency induction furnace 2, a limit switch 12 for cooperating with the translation base 6 is also installed on the support 1 directly below the high-frequency induction furnace 2. When the translation base 6 moves to the designated position, the limit switch 12 will be triggered, thereby controlling the translation driving device 7 to stop moving, ensuring the accurate positioning of the smelting crucible 3 and the steel materials during the smelting process.

[0027] The actual use process of the device is as follows:

[0028] 1. Place the steel materials to be smelted into the smelting crucible 3, ensuring that the steel materials are placed stably and tightly to avoid movement or dumping during the smelting process;

[0029] Place the smelting crucible 3 containing the steel materials on the positioning groove of the furnace base 4, ensuring that the positioning protruding column 10 closely cooperates with the positioning groove to enhance the stability of the smelting crucible 3;

[0030] 2. Start the lifting drive cylinder to vertically lift the furnace base 4 and the smelting crucible 3 to the furnace mouth of the high-frequency induction furnace 2;

[0031] After the furnace base 4 is lifted to the designated position, start the translation drive cylinder to move the translation base 6 and the furnace base 4 in the horizontal direction to directly below the high-frequency induction furnace 2;

[0032] Ensure that the translation base 6 stops moving when it moves to the limit switch 12 to ensure accurate positioning of the smelting crucible 3 and the steel material during the smelting process;

[0033] 3. Start the high-frequency control power supply 9 of the high-frequency induction furnace 2 to make the high-frequency induction coil 8 generate a strong alternating magnetic field, thereby generating eddy currents in the steel placed therein, achieving rapid heating and melting of the steel;

[0034] During the smelting process, the power and frequency of the high-frequency control power supply 9 can be adjusted as needed to control the smelting speed and temperature;

[0035] At the same time, the completion of the smelting process can be judged by observing the flame color at the upper furnace mouth and the melting state of the steel material in the smelting crucible 3;

[0036] 4. When the steel is completely melted, turn off the high-frequency control power supply 9 and stop heating the high-frequency induction furnace 2;

[0037] Start the lifting drive cylinder to vertically lower the furnace base 4 and the smelting crucible 3 to the designated position;

[0038] Start the translation drive cylinder to move the translation base 6 and the furnace base 4 in the horizontal direction to the unloading area;

[0039] In the unloading area, the smelting crucible 3 is removed from the furnace base 4, and the molten steel is poured out for subsequent processing.

[0040] In summary, the rapid smelting device for recycling steel materials achieves rapid smelting and efficient recycling of steel materials through ingenious design, has the advantages of convenient operation, strong stability, high smelting efficiency, etc., and provides strong technical support for the recycling of recycled steel materials.
