[0018] Preferably, a power control box is installed on the top of the bottom plate, and the power control box is located on one side of the bearing seat. A shell is installed on the top end of the power control box. A three-phase low-frequency power supply is installed inside the shell.

[0019] Preferably, the usage method of this automatic alloy steel melting equipment is as follows:

[0020] S1. Place the alloy steel raw materials to be processed inside the storage box. The storage box stores the alloy steel raw materials. When feeding is required, the telescopic rod shortens and drives the movable plate to move towards the inside of the storage shell, so that the two movable plates open. The raw materials enter the inside of the transfer pipe under the influence of gravity. The transfer pipe guides the steel raw materials into the inside of the crucible, which is convenient for the device to automatically control the addition of raw materials;

[0021] S2. The power control box transmits power to the electromagnetic induction coil. When the electromagnetic induction coil is energized to generate an alternating magnetic field, eddy current is generated on the pipe wall to heat up, and the inner crucible and raw materials are heated. When the temperature rises above Celsius, the raw materials can be completely melted into a metal liquid state. During the heating process, the temperature sensor senses the temperature change, and the temperature sensor transmits the sensed temperature to the power control box. The power control box controls the operating frequency of the heating structure to control the temperature change;

[0022] S3. During the melting of the metal, the three-phase low-frequency power supply operates and transmits power to the electromagnetic induction coil. When a low-frequency current is passed through the electromagnetic induction coil, a low-frequency traveling magnetic field will be generated. The magnetic field passes through the bottom of the crucible and acts on the metal solution. Inductive electromotive force and current are generated in the metal solution, and the current acts with the magnetic field to generate electromagnetic force, which thus drives the metal solution to rotate directionally, playing a role in stirring, making the alloy steel raw materials fully mixed, and improving the quality of the alloy steel;

[0023] S4. After the stirring of the metal solution is completed, the electric adjusting rod extends to drive the movable seat at the top to move backward. The movable seat drives the assembly shaft to move and drives the displacement of the limit groove. The limit groove drives the bottom end of the outer box to tilt backward, adjusting the angle of the crucible inside the outer box. The outer box adjusts the angle with the connecting seat and the connecting shaft as the center, making the crucible tilt and the drainage port tilt downward. The metal solution flows out under the guidance of the drainage port, and the metal solution is transmitted to the inside of the casting mold under the guidance of the output port for alloy steel mold processing.

[0024] Preferably, in the step S3, the following steps are further included:

[0025] S31. During the heating process of the electromagnetic induction coil, the inside is separated from the outside through the heat insulation layer, slowing down the heat transfer between the inside and the outside, realizing energy recovery, and avoiding the situation of energy waste.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. The present invention is equipped with an electromagnetic induction coil. During the melting of the metal, the three-phase low-frequency power supply operates and transmits power to the electromagnetic induction coil. When a low-frequency current is passed through the electromagnetic induction coil, a low-frequency traveling magnetic field will be generated. The magnetic field passes through the bottom of the crucible and acts on the metal solution. Inductive electromotive force and current are generated in the metal solution, and the current acts with the magnetic field to generate electromagnetic force, which thus drives the metal solution to rotate directionally, playing a role in stirring, making the alloy steel raw materials fully mixed, and improving the quality of the alloy steel.

[0028] 2. The present invention is equipped with a storage box and a telescopic rod. The transfer pipe fixes the storage box at the top. The alloy steel raw materials to be processed are placed inside the storage box. The two movable plates are closed together, and the storage box stores the alloy steel raw materials. When blanking is required, the telescopic rod shortens, driving the movable plates to move inward into the receiving shell, causing the two movable plates to open. The raw materials enter the interior of the transfer pipe under the influence of gravity, and the transfer pipe guides the steel raw materials into the interior of the crucible, facilitating the automatic control of raw material addition by the device.

[0029] 3. The present invention is equipped with an electric adjustment rod. After the stirring of the molten metal is completed, the electric adjustment rod extends, driving the movable seat at the top to move backward. The movable seat drives the assembly shaft to move, driving the displacement of the limit groove. The limit groove drives the bottom end of the outer box to tilt backward, adjusting the angle of the crucible inside the outer box. The outer box adjusts the angle with the connecting seat and the connecting shaft as the center, causing the crucible to tilt and the drainage port to tilt downward. By controlling the length of the electric adjustment rod, the tilting angle of the crucible is adjusted. Due to the tilting of the crucible, the drainage port guides the molten metal to flow out, and the molten metal is transmitted into the interior of the casting mold under the guidance of the output port for alloy steel mold processing.

[0030] 4. The present invention is equipped with a top cover and a connecting plate. The top cover fixes the connecting plates at both ends. The connecting plates fix the support pipes. The inner side of the support pipe limits the fastening screws through threads. Rotating the fastening screws moves them toward the outer side walls of the outer box. The fastening screws abut against the outer side walls of the outer box to ensure the stability of the connecting plates, facilitating the fixing of the top cover at the top by the connecting plates, enabling the top cover to stably fix the material storage assembly. After the processing is completed, the user separates the connecting plate from the outer box by removing the fastening screws and removes the top cover, facilitating the user to maintain the interior of the melting device and extending the service life of the melting device.

[0052] Furthermore, the usage method of this alloy steel automatic melting equipment is as follows:

[0053] S1. Place the alloy steel raw materials to be processed inside the storage box 25. The storage box 25 stores the alloy steel raw materials. When feeding is required, the telescopic rod 23 shortens to drive the movable plate 24 to move toward the inside of the storage shell 22, causing the two movable plates 24 to open. The raw materials enter the inside of the transmission pipe 21 under the influence of gravity.

[0054] S2. The power control box 36 transmits power to the electromagnetic induction coil 6. The energized alternating magnetic field of the electromagnetic induction coil 6 generates eddy current heat on the pipe wall, heating the inner crucible and raw materials. The temperature rises above 1580 degrees Celsius, enabling all the raw materials to be melted into a metal liquid state. During the heating process, the temperature sensor 20 senses the temperature change, and the temperature sensor 20 transmits the sensed temperature to the power control box 36. The power control box 36 controls the operating frequency of the heating structure to control the temperature change;

[0055] S3. During the melting of the metal, the three-phase low-frequency power supply 38 operates and transmits power to the electromagnetic induction coil 6. When a low-frequency current is passed through the electromagnetic induction coil 6, a low-frequency traveling magnetic field is generated.

Inductive electromotive force and current are generated in the metal solution, and the current interacts with the magnetic field to generate an electromagnetic force, thereby driving the metal solution to rotate directionally, playing a stirring role, enabling the alloy steel raw materials to be fully mixed, and improving the quality of the alloy steel;

[0056] S4. After the stirring of the metal solution is completed, the electric adjusting rod 33 extends to drive the movable seat 32 at the top to move backward. The movable seat 32 drives the assembly shaft 31 to move, driving the displacement of the limit groove 30. The limit groove 30 drives the bottom end of the outer box 1 to tilt backward, adjusting the angle of the crucible 7 inside the outer box 1. The outer box 1 adjusts the angle with the connecting seat 26 and the connecting shaft 27 as the center, causing the crucible 7 to tilt and the drainage port 8 to tilt downward. The metal solution flows out under the guidance of the drainage port 8, and the metal solution is transmitted to the inside of the casting mold under the guidance of the output port 12 for alloy steel mold processing.

[0057] Further, in the step S3, the following steps are further included:

[0058] S31. During the heating process of the electromagnetic induction coil 6, the inside is separated from the outside through the heat insulation layer 2, slowing down the heat transfer between the inside and the outside, realizing energy recovery, and avoiding energy waste.

[0059] Working principle: Place the alloy steel raw material to be processed inside the storage box 25. The storage box 25 stores the alloy steel raw material. When blanking is required, the telescopic rod 23 shortens, driving the movable plate 24 to move towards the inside of the receiving shell 22, causing the two groups of movable plates 24 to open. The raw material enters the inside of the transmission pipe 21 under the influence of gravity. The transmission pipe 21 guides the steel raw material into the inside of the crucible 7, facilitating the automatic control of raw material addition by the device. The control box 36 transmits electricity to the electromagnetic induction coil 6. The electromagnetic induction coil 6 generates an alternating magnetic field when energized, causing eddy current heating on the pipe wall. The crucible and the raw material inside are heated, and the temperature rises above 1580 degrees Celsius, enabling the raw material to be completely melted into a metal liquid state. During the heating process, the temperature sensor 20 senses the temperature change. The temperature sensor 20 transmits the sensed temperature to the control box 36. The control box 36 controls the operating frequency of the heating structure to control the temperature change. During the melting of the metal, the three-phase low-frequency power supply 38 operates and transmits electricity to the electromagnetic induction coil 6. When a low-frequency current is passed through the electromagnetic induction coil 6, a low-frequency traveling magnetic field is generated. The magnetic field passes through the bottom of the crucible 7 and acts on the metal solution. An induced electromotive force and current are generated in the metal solution. The current acts with the magnetic field to generate an electromagnetic force, thereby driving the metal solution to rotate directionally, playing a stirring role, enabling the alloy steel raw material to be fully mixed, and improving the quality of the alloy steel. After the stirring of the metal solution is completed, the electric adjusting rod 33 extends, driving the movable seat 32 at the top to move backward. The movable seat 32 drives the assembly shaft 31 to move, driving the displacement of the limit groove 30. The limit groove 30 drives the bottom end of the outer box 1 to tilt backward, adjusting the angle of the crucible 7 inside the outer box 1. The outer box 1 adjusts the angle with the connecting seat 26 and the connecting shaft 27 as the center, causing the crucible 7 to tilt and the drainage port 8 to tilt downward. The metal solution flows out under the guidance of the drainage port 8. The metal solution is transmitted to the inside of the casting mold under the guidance of the output port 12 for alloy steel mold processing. During the heating process of the electromagnetic induction coil 6, the inside is separated from the outside through the heat preservation layer 2, slowing down the heat transfer between the inside and the outside, realizing energy recovery, and avoiding energy waste.
