[0018] The present invention provides Figure 1-Figure 7A nickel-based high-temperature alloy vacuum induction melting equipment shown in the figure comprises a box body 1, a feeding mechanism 2 is arranged inside the box body 1, a reciprocating motion mechanism 3 is arranged on one side of the feeding mechanism 2, and a quenching mechanism 4 is arranged inside the box body 1; the quenching mechanism 4 comprises a support block 5 fixedly connected to the bottom of the box body 1, a water outlet hole 6 is opened inside the support block 5, a water outlet pipe 7 is fixedly connected to one side of the outer wall of the support block 5, the water outlet pipe 7 passes through one side of the outer wall of the box body 1 and is fixedly connected to the box body 1, a special-shaped ring 8 is fixedly connected to the top of the support block 5, a first bellows 9 is fixedly connected to the top of the special-shaped ring 8, and the first bellows 9 passes through the outer wall of the box body 1. The outer wall of the special-shaped ring 8 is fixedly connected to the box body 1, and the outer shell 10 is rotatably connected inside. Circular holes 11 are opened at both ends of the outer shell 10. A special-shaped water inlet pipe 12 is penetrated on one side of the outer wall of the outer shell 10. The special-shaped water inlet pipe 12 is located inside the outer shell 10 and is fixedly connected to a plurality of nozzles 13 at one end. A second bellows 14 is fixedly connected to the outer wall of the special-shaped water inlet pipe 12 away from the nozzle 13. The second bellows 14 penetrates one side of the outer wall of the box body 1 and is fixedly connected to the box body 1.

At the same time, the shell 10 reciprocates and intermittently rotates in the support block 5, so that the water flow sprayed from the nozzle 13 is evenly sprayed on the alloy 29, and the alloy 29 is evenly quenched to reduce the deformation of the alloy 29 during quenching. The water vapor generated during the coolant quenching rises, first passes through the special-shaped water inlet pipe 12 with coolant inside, and part of the water vapor condenses into liquid and descends, and part of the water vapor enters the first bellows 9.

The first rod 19 drives the rack 18, and the rack 18 drives the incomplete gear 17 to deflect back and forth.

[0019] Furthermore, in the above technical scheme, the feeding mechanism 2 includes four first shafts 23 rotatably connected to the box body 1, one of the first shafts 23 passes through one side of the outer wall of the box body 1, a feeding roller 24 is fixedly connected to the outer peripheral surface of the first shaft 23, a gear 25 is fixedly connected to the outer peripheral surface of the first shaft 23, and a first bevel gear 26 is fixedly connected to the end of the first shaft 23 away from the feeding roller 24, a second bevel gear 27 is meshed with one side of the outer wall of the first bevel gear 26, and a second shaft 28 is fixedly connected inside the second bevel gear 27, the second shaft 28 is rotatably connected to the box body 1, and the second shaft 28 is fixedly connected to the cam 22. The feeding roller 24, the first gear 25 and the first bevel gear 26 are driven to rotate by the first shaft 23, so that the four feeding rollers 24 rotate synchronously, driving the alloy 29 to move forward at a uniform speed, and the second shaft 28 is used to drive the cam 22 to rotate, so that the feeding mechanism 2 drives the reciprocating motion mechanism 3 to work.

[0020] Furthermore, in the above technical solution, the four feeding rollers 24 on the four first shafts 23 are fitted in pairs, and an alloy 29 is rollingly connected between the two feeding rollers 24. The alloy 29 runs through the box body 1 and the outer shell 10. The four gears 25 on the four first shafts 23 are meshed in pairs, and the alloy 29 is moved to the quenching mechanism 4 at a uniform speed through the feeding rollers 24.

[0021] Furthermore, in the above technical solution, a support plate is fixedly connected to one side of the outer wall of the box body 1, a motor 30 is fixedly connected to the top of the support plate, an output shaft of the motor 30 is fixedly connected to a first shaft 23 that passes through one side of the outer wall of the box body 1, the first bellows 9 is fixedly connected to an external air pump, the second bellows 14 is fixedly connected to an output end of an external water pump, the water outlet pipe 7 is fixedly connected to an external water storage tank, and the output power is provided by the motor 30 to drive the feeding mechanism 2 and the reciprocating motion mechanism 3 to work, and cooperate with the quenching mechanism 4 to quench the alloy 29, absorb the water vapor, and recover the coolant after quenching.

[0022] Furthermore, in the above technical solution, an electromagnetic heating device is provided on one side of the outer wall of the box body 1, and an induction coil 31 is fixedly connected to one side of the outer wall of the electromagnetic heating device. The induction coil 31 passes through one side of the outer wall of the box body 1 and is fixedly connected to the box body 1. The induction coil 31 is spirally distributed on the outside of the alloy 29. A high-density magnetic field is generated in the induction coil through the electromagnetic heating device, and a large eddy current is generated in the alloy 29. The alloy 29 relies on its own internal resistance to generate heat and electromagnetic heating.

[0023] The specific implementation method is as follows: when working, the motor 30, the external water pump and the external air pump are started, and the coolant is injected into the second bellows 14, and the coolant is sprayed out from the nozzle 13 through the special-shaped water inlet pipe 12. The motor 30 drives the feeding mechanism 2 to pass the alloy 29 through the induction coil 31 and the quenching mechanism 4 at a uniform speed. The alloy 29 passing through the induction coil 31 is heated, and the feeding mechanism 2 drives the reciprocating mechanism 3 to work, and the reciprocating mechanism 3 drives the incomplete gear 17 to reciprocate, and the incomplete gear 17 drives the shell 10 to rotate in the support block 5, and the nozzle 13 in the shell 10 reciprocates accordingly. The water sprayed from the nozzle 13 is evenly sprayed on the outer peripheral surface of the nozzle 13, thereby reducing the bending deformation of the alloy 29 during quenching, and at the same time, the water vapor generated during quenching The air rises, and part of the water vapor contacts the special-shaped water inlet pipe 12 and condenses, and then enters the water outlet 6 in the support block 5 along with the coolant heated after quenching, and then is discharged for recovery. The normal quenching alloy 29 will bend due to deformation, and when the feeding roller 24 in the feeding mechanism 2 drives the alloy 29 to move, there is friction between the feeding roller 24 and the alloy 29. The alloy 29 needs to overcome the friction to bend and deform, so the feeding mechanism 2 further reduces the deformation of the alloy 29 during quenching. After the heated alloy 29 enters the shell 10, the feeding mechanism 2 drives the reciprocating motion mechanism 3, and the reciprocating motion mechanism 3 drives the shell 10 to deflect back and forth, so that the coolant sprayed by the nozzle 13 is evenly sprayed on the outer peripheral surface of the alloy 29. The alloy 29 is uniformly heated and quenched, and the deformation of the alloy 29 during quenching is reduced. The generated water vapor first condenses through the special-shaped water inlet pipe 12 and then flows down, and the air is sucked into the circular hole 11, driving the remaining water vapor to be discharged from the first bellows 9. The condensed water vapor plus the coolant heated after quenching are recycled from the water outlet pipe 7. The alloy 29 is uniformly passed through the induction coil 31 and the quenching mechanism 4 through the feeding mechanism 2. Since the length of the alloy 29 changes due to bending deformation, there is friction between the feeding roller 24 and the alloy 29, so that the alloy 29 needs to overcome the friction to bend and deform, which increases the difficulty of quenching and deformation of the alloy 29. The device occupies a small area, has a simple structure, is easy to operate, and does not require manual operation. The quenching effect of alloy 29 is good, and the water vapor and the coolant after quenching are recycled, so that the water vapor will not scald the personnel, the water vapor in the box body 1 is reduced, and the rust rate of parts is reduced. This implementation method specifically solves the problem that thin-walled parts are often quenched by pipe spraying in the prior art. When the pipe is sprayed on alloy 29, one side contacts first and the other side contacts later, resulting in inconsistent cooling speed, and alloy 29 will become soft after quenching, so that alloy 29 will deform after quenching, and the water vapor generated during quenching may scald the staff. Part of the coolant during quenching splashes out, causing humidity in the surrounding area, accelerating the rust of surrounding iron products, and affecting the service life of the device.

[0024] The present invention also provides a smelting method using the above-mentioned nickel-based high-temperature alloy vacuum induction melting equipment, the method comprising the following steps: Step 1: When working, start the motor 30, the external water pump and the external air pump, and inject the coolant into the second bellows 14, and the coolant is sprayed out from the nozzle 13 through the special-shaped water inlet pipe 12; Step 2: The motor 30 drives the feeding mechanism 2 to pass the alloy 29 through the induction coil 31 and the quenching mechanism 4 at a uniform speed. The alloy 29 passing through the induction coil 31 is heated, and the feeding mechanism 2 drives the reciprocating mechanism 3 to work. The reciprocating mechanism 3 drives the incomplete gear 17 to reciprocate, and the incomplete gear 17 drives the housing 10 to rotate in the support block 5. The nozzle 13 in the housing 10 reciprocates accordingly, and the water sprayed by the nozzle 13 is evenly sprayed on the outer peripheral surface of the nozzle 13, thereby reducing the bending deformation of the alloy 29 during quenching. The water vapor generated during quenching rises, and part of the water vapor contacts the special-shaped water inlet pipe 12 and condenses, and then enters the water outlet hole 6 in the support block 5 along with the coolant heated after quenching, and is then discharged for recovery. Normal quenching deformation of the alloy 29 will cause bending, and when the feeding roller 24 in the feeding mechanism 2 drives the alloy 29 to move, there is friction between the feeding roller 24 and the alloy 29. The alloy 29 needs to overcome the friction to bend and deform, so the feeding mechanism 2 further reduces the deformation of the alloy 29 during quenching.
