Description

Technical Field

[0001] The invention belongs to the technical field of heat treatment, in particular to a nickel-based alloy heat treatment device. Background Art

[0002] Heat treatment of nickel-based alloys is a key step in optimizing their mechanical properties, corrosion resistance, and high-temperature stability through processes such as solution treatment, aging, annealing, and quenching. When nickel-based alloy workpieces need to be quenched to improve performance, they need to undergo pretreatment, heating, insulation, and cooling. During the cooling process, a lifting device will lift the frame containing the nickel-based alloy workpiece into the quenching tank until the workpiece cools to the required temperature.

[0003] However, after long-term use, quenching oil will oxidize and polymerize, producing sludge and gum, increasing viscosity and reducing cooling capacity; or dissolved oxygen in water will cause metal ions to precipitate, forming a large amount of impurities such as scale. During the quenching cooling process, oxide impurities such as iron oxide may form on the surface of the workpiece, affecting the quenching effect of the workpiece; there are impurities in the water or oil in the quenching medium, such as oil stains, which may also adhere to the surface of the workpiece, causing quality problems such as oxidation, contamination, and spots, affecting the appearance and surface quality of the workpiece; impurities may also form oxide films on the surface, increasing the thermal resistance between the quenching medium and the workpiece surface, affecting the quenching cooling rate and reducing the quenching effect; and, when the high-temperature workpiece first contacts the coolant, the surface quickly vaporizes to form a steam film. If the steam cannot dissipate in time, it will hinder subsequent cooling, affecting the quenching effect and causing the heat treatment effect of the nickel-based alloy workpiece to be affected.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings shown in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1:

[0035] In order to effectively solve the above problems, as shown in the accompanying drawings of the specification Figures 1-11 As shown, a nickel-based alloy heat treatment equipment includes a quenching tank 1, a cooling circulation system, a liquid inlet 11, and a liquid outlet 12; the cooling circulation system is a conventional component of the quenching tank 1, and the cooling liquid is transported into the quenching tank 1 through the liquid inlet 11, and the cooling liquid is withdrawn from the liquid outlet 12 and then flows back into the inlet through the cooling circulation system to circulate the cooling liquid in the quenching tank 1;

[0036] Also includes:

[0037] A liquid outlet pipe 13 is provided at the liquid outlet end 12 in the quenching tank 1, and a rotating pipe 14 is rotatably connected in the liquid outlet pipe 13. The top of the rotating pipe 14 is connected to the No. 1 motor 15 provided in the quenching tank 1, and a rotating plate 16 is distributed in an annular manner on the rotating pipe 14; suction holes 17 are distributed in an annular manner near the top of the rotating pipe 14, and the rotating pipe 14 is provided with an ejection hole 18 above the suction hole 17. An ejection pipe 19 is provided in the quenching tank 1, and the top of the rotating pipe 14 passes through the ejection pipe 19, and the ejection pipe 19 is rotatably connected to the rotating pipe 14; the inner walls of the top and bottom of the ejection pipe 19 are respectively located above and below the ejection hole 18, and a three-way valve is provided in the ejection pipe 19, and one end is connected to the liquid outlet end 12, and the other end faces the quenching tank 1;

[0038] A pump 2 is installed on one side of the quenching tank 1 and is connected to the ejection pipe 19 to pump the solution in the rotating tube 14 into the ejection pipe 19. A float box 21 is provided in the quenching tank 1, and the float box 21 slides on the inner wall of the quenching tank 1, and the edge of the float box 21 contacts the surface of the liquid outlet pipe 13. A circulation pipe 22 is provided in the quenching tank 1, and the circulation pipe 22 is close to the liquid outlet end 12. Both ends of the circulation pipe 22 are connected to the quenching tank 1. A circulation pump 23 is installed at the part of the circulation pipe 22 away from the port, and a comprehensive monitoring instrument 24 is installed on the circulation pipe 22.

[0039] The liquid outlet pipe 13 can also be installed at the liquid inlet end 11. The liquid outlet pipe 13 of the liquid inlet end 11 works when cleaning the quenching pool 1 and stops working when quenching. The liquid outlet pipe 13 of the liquid outlet end 12 continues to work, thereby improving the filtering and cleaning efficiency of the coolant; the pump 2 is a conventional device for the flow of coolant. The pump 2 extracts the coolant in the liquid outlet pipe 13 through the suction hole 17 on the rotating pipe 14, and enters the ejection pipe 19 through the ejection hole 18. The filtered coolant is re-ejected into the quenching pool 1 through the ejection pipe 19; the circulating pump 23 is a conventional device for sucking coolant, and the comprehensive monitor 24 is a conventional coolant detection instrument, such as a laser sensor. The sensor displays the particle size level in real time and can set the alarm threshold; the inlet of the circulation pipe 22 is divided into three parts, which are respectively located in the upper layer, middle layer and bottom layer of the quenching tank 1. The middle of the circulation pipe 22 is merged into a pipe, where the integrated monitor 24 is installed. The outlet of the circulation pipe 22 is distributed on the surface of the liquid outlet pipe 13 and faces the bottom of the liquid outlet pipe 13; the top of the float box 21 is a hollow box, and a sealing plug is provided at the bottom of the float box 21, so that the coolant can be gathered in the float box 21, and by removing the sealing plug, the coolant passes through the bottom of the float box 21. The density of the float box 21 is less than that of the coolant or air is stored in the inner wall of the float box 21 to increase buoyancy;

[0040] Specific working process: in the working interval of the quenching pool 1, the impurities contained in the coolant include floating, suspended and deposited impurities, and the impurities in the quenching pool 1 need to be filtered. The No. 1 motor 15 drives the rotating plate 16 to rotate through the rotating tube 14, and the rotating plate 16 drives the coolant in the liquid outlet pipe 13 to rotate. The coolant is affected by the centrifugal force, so that the impurities contained in it are thrown to the inner wall of the liquid outlet pipe 13, and the coolant remains around the rotating tube 14; then, the pump 2 draws the coolant around the rotating tube 14 into the ejection pipe 19 through the suction hole 17 and the ejection hole 18, and sprays it into the quenching pool 1 through the ejection pipe 19, and the coolant in the liquid outlet pipe 13 is reduced. The contaminated coolant in the quenching pool 1 enters the liquid outlet pipe 13 under the influence of gravity, and the coolant is filtered inside the liquid outlet pipe 13, and then ejected from the ejection pipe 19, thereby achieving the effect of filtering impurities during the circulation of the coolant in the quenching pool 1, reducing the impurity content in the coolant, and avoiding excessive impurity content that affects the heat treatment effect of the nickel-based alloy workpiece;

[0041] During the cleaning of the quenching tank 1 during the working interval, the worker places the float box 21 on the liquid surface in the quenching tank 1. The float box 21 floats on the liquid surface of the coolant, and the ejection pipe 19 sprays the filtered coolant to the top of the float box 21. The filtered coolant is collected in the float box 21, and the sealing plug at the bottom of the float box 21 is in a sealed state. The filtered coolant is stored in the float box 21, separating the two coolants to avoid mixing and affecting each other, thereby reducing the filtering efficiency of the coolant. Moreover, compared with the method of transporting the coolant to the external filtering equipment through a pipeline, the time-consuming method leads to a long working interval of the quenching tank 1, which reduces the quenching efficiency and requires regular replacement and cleaning of the filtering equipment at a cost of extra time and cost.

[0042] As the coolant in the float box 21 increases, the coolant at the bottom of the float box 21 decreases. As the coolant at the bottom decreases, the float box 21 descends along the quenching pool 1, and with the coolant gathered inside and its own weight, it scrapes the inner wall of the quenching pool 1 and the surface of the liquid outlet pipe 13, reducing impurities attached to the quenching pool 1, improving the cleanliness, and avoiding secondary contamination of the coolant. This achieves the effect of filtering the coolant while cleaning the inside of the quenching pool 1. The combination of these two effects improves the cleanliness of the workpiece quenching environment, thereby improving the quenching effect.

[0043] After the coolant at the bottom of the float box 21 is completely pumped out and filtered, the worker removes the sealing plug through a conventional electric lifting device, and the coolant passes through the sealing plug and returns to the quenching pool 1. The float box 21 floats to the top of the quenching pool 1 due to its own floating effect, and the floating, suspended and deposited impurities in the quenching pool 1 are pumped out, filtered and collected in the liquid outlet pipe 13. Some floating impurities will also adhere to the bottom of the float box 21. After the worker moves the float box 21 away from the quenching pool 1 through the electric lifting device, the impurities adhered to the bottom of the float box 21 are away from the quenching pool 1 and the coolant, thereby improving the cleanliness of the quenching pool 1 and thus improving the quenching effect. At this time, the float box 21 can be placed on the ground, and the worker can quickly clean the box-shaped float box 21 by conventional cleaning methods.

[0044] When quenching begins after filtration, the liquid inlet end 11 transports the coolant to the liquid outlet end 12, and the coolant is then drawn into the liquid outlet end 12 by the liquid outlet pipe 13, and is discharged into the quenching tank 1 through the liquid inlet end 11 again through the cooling circulation system, so that the coolant forms a flowing effect; when the workpiece is immersed in the coolant, the flowing coolant, on the one hand, flushes the workpiece, takes away impurities, and prevents them from adhering to the surface of the workpiece, affecting the surface cleanliness after quenching, thereby improving the quenching effect; on the other hand, when the high-temperature workpiece just contacts the coolant, the surface quickly vaporizes to form a steam film. If the steam cannot escape in time, it will hinder subsequent cooling. Therefore, the steam film is destroyed by the flushing effect of the flowing coolant, thereby improving the subsequent cooling effect, which helps workers to more accurately control the cooling rate, thereby improving the quenching effect;

[0045] During quenching, the coolant flows toward the liquid outlet 12. During the flow, the circulating pump 23 draws the coolant from the upper, middle, and lower layers of the quenching pool 1 through the three inlets of the circulating pipe 22. By drawing the coolant from multiple locations to test samples, the comprehensiveness of the test is improved, and the test accuracy is improved. When the coolant passes through the middle part of the circulating pipe 22, the comprehensive monitor 24 detects the coolant passing through. Workers use the test data of the coolant after quenching to assist in judging the quenching quality. For example, if the amount of impurities such as metal debris and oxide scale in the quenching liquid increases, it may indicate that the surface of the workpiece is severely oxidized or localized shedding occurs during the quenching process, which indirectly reflects whether the quenching temperature and holding time are reasonable. Alternatively, if the concentration of the water-based quenching liquid deviates from the set value, it will directly affect the cooling capacity. If the concentration is too low, the cooling rate may be close to that of water, increasing the risk of cracking. If the concentration is too high, the cooling efficiency may be reduced, resulting in insufficient hardness.

[0046] During the coolant circulation process, the liquid outlet pipe 13 filters the coolant to reduce impurities in the coolant and prevent the coolant containing impurities from contacting the workpiece, which affects the workpiece and the detection data, resulting in a chain reaction. Moreover, when the quenching pool 1 is cleaned during working intervals, the circulation pipe 22 can also detect whether the coolant filtration meets the standards, which facilitates the workers to control the cleaning time. Moreover, the circulation pump 23 flushes the tested coolant to the surface of the liquid outlet pipe 13. When the floating box 21 does not contact the circulation pipe 22, the outlet of the circulation pipe 22 flushes the impurities attached to the surface of the liquid outlet pipe 13 to the bottom and is sucked away by the liquid outlet pipe 13, thereby improving the impurity removal efficiency. In addition, even if some impurities are not washed away but adhere to each other, the circulation pipe 22 will continue to suck and spray, accelerate the flow of coolant, and promote the impurities in the coolant to adhere to the surface of the liquid outlet pipe 13, which is convenient for the floating box 21 to scrape and clean them.

[0047] Example 2:

[0048] On the basis of the first embodiment, a lifting platform 25 is provided in the middle of the bottom of the quenching pool 1, and a protrusion 26 is distributed in an annular manner on the top of the lifting platform 25, one side of the protrusion 26 is a vertical surface and the other side is an inclined surface; a tray 27 with a T-shaped cross section is provided on the top of the lifting platform 25, and the center of the rod-shaped bottom of the tray 27 is located in the square groove 28 opened in the center of the lifting platform 25, and a block 29 is slidably connected in the square groove 28, and a No. 2 motor 3 is provided in the block 29 and connected to the rod-shaped bottom of the tray 27; a ball 31 is provided at the bottom of the tray 27 to roll along the surface of the protrusion 26; A clamping block 32 is slidably connected to the tray 27 via a spring; an extension tube 33 is provided at the bottom of the liquid outlet pipe 13, and one end of the extension tube 33 is close to the middle position of the quenching tank 1, and suction grooves 34 are evenly provided on the top of the extension tube 33; the lifting platform 25 can also be located near the liquid inlet end 11, and the installation position can be determined according to actual needs; the nickel-based alloy workpiece is placed in a conventional loading basket, and is placed in the quenching tank 1 with the loading basket to complete the quenching work in large quantities; the loading basket is made of conventional high-temperature resistant material, and the loading basket is a frame structure, and the coolant enters the loading basket through the holes to contact the workpiece;

[0049] The extension tube 33 is slidably connected to a closing plate 35 via a spring. The closing plate 35 is evenly provided with closing grooves 36. The suction groove 34 coincides with the closing grooves 36. The lifting platform 25 is provided with a connecting rope 37, and one end of the connecting rope 37 is connected to the closing plate 35. A guide wheel 38 is provided at the bottom of the quenching tank 1. The middle part of the connecting rope 37 is wound around the guide wheel 38.

[0050] The bottom of the quenching tank 1 is evenly provided with scraping strips 39, which surround and contact the outer surface of the closing plate 35;

[0051] Scrapers 4 are provided on both sides of the closing plate 35. The scrapers 4 are located between adjacent scraper bars 39 and contact the bottom of the quenching tank 1. The suction groove 34 is located at the top and both sides of the extension tube 33, and the closing groove 36 is partially located at the top of the closing plate 35 and partially located on both sides.

[0052] Specific work flow: When cleaning the quenching pool 1, the conventional lifting platform 25 drives the tray 27 to the bottom of the quenching pool 1 to avoid affecting the descent of the floating box 21; during quenching, the lifting platform 25 rises away from the liquid surface, and the worker places the loading basket loaded with workpieces on the top of the tray 27 through the electric lifting device. The block 32 on the top of the tray 27 is squeezed and moved away from the center of the tray 27 until the loading basket is completely placed on the tray 27. The block 32 is located in the hole of the loading basket, so that the block 32 is no longer squeezed and retracts through the spring to fix the loading basket on the tray 27; then, the No. 2 motor 3 drives the tray 27 to rotate by a conventional driving method. Since the No. 2 motor 3 is installed in the block 29, the block 29 can be raised and lowered in the square groove 28 but cannot rotate, so that the second motor 3 can drive the tray 27 to rotate; when the tray 27 drives the ball 31 to rotate past the protrusion 26, it rolls along the inclined surface of the protrusion 26 to the vertical surface and falls on the top of the lifting platform 25, causing vibration. The block 29 slides up and down in the square groove 28, so that the tray 27 drives the workpiece in the loading basket to rotate and vibrate at the same time. The rotation and vibration can destroy the steam film formed on the surface of the workpiece, promote the coolant to penetrate the workpiece surface faster, and avoid uneven cooling rate caused by localized steam film residue. For example, if the steam film on a certain part of the workpiece is not broken in time, it may cause insufficient hardness or stress concentration in that area, affecting the quenching effect;

[0053] Moreover, if impurities such as oxide scale are generated after the coolant contacts the workpiece, the rotation and vibration can vibrate them from the gaps between the workpieces through mechanical force, causing the impurities to loosen and weaken the adhesion, and then throw them out through centrifugal action to avoid local cooling obstruction caused by impurity deposition; moreover, the coolant enters from one side of the loading basket and flows out from the other side, making the coolant contact with different temperatures on both sides of the loading basket. At the same time, the impurities generated will also flow from one side to the workpiece on the other side, which will affect the quenching effect of the workpieces on both sides for a long time, while the rotation will make the workpieces on each side contact the flowing coolant in turn. While cooling evenly, impurities are thrown away by centrifugal action to improve the cooling effect. In addition, workers can install the inlet of the circulation pipe 22 on the inner wall of the quenching tank 1 near the lifting platform 25, so that impurities can be thrown near the circulation pipe 22, prompting the impurities in the quenching process to be sucked and detected by the circulation pipe 22, providing quenching data to workers more quickly and improving the detection effect. The circulation pipe 22 can also be used to suck and discharge impurities to the liquid outlet pipe 13, preventing impurities from scattering in the coolant for a long time, making it difficult to collect, and improving the cleanliness of the coolant.

[0054] Furthermore, the liquid outlet pipe 13 draws coolant through the suction groove 34 on the extension pipe 33, so that the suspended and impurities about to settle are drawn away with the coolant, so that the coolant flowing through the workpiece drives the impurities to flow along a unified flow path, thereby preventing the impurities from being scattered in the coolant and adhering to the inner wall of the quenching tank 1 or the surface of the workpiece, causing the quenching tank 1 to need frequent cleaning and affecting the quenching efficiency. In addition, the extension pipe 33 can also expand the suction range of the liquid outlet pipe 13 and improve the impurity removal efficiency.

[0055] When the lifting platform 25 rises, the closing plate 35 is pulled by the pull rope to move, so that the suction groove 34 and the closing groove 36 coincide with each other, and the suction grooves 34 on both sides of the extension tube 33 are covered and sealed by the closing plate 35. The suction groove 34 at the top of the extension tube 33 coincides with the closing groove 36 at the top of the closing plate 35, and the coolant begins to be sucked, that is, the extension tube 33 sucks in the direction of the impurities being thrown upward, thereby accelerating the efficiency of the impurities being sucked away and improving the cleanliness of the quenching pool 1; when the lifting platform 25 descends, the pull rope is loosened, and the closing groove 36 is reset by the spring. The cooling fluid is forced to move along the bottom of the quenching tank 1, thereby preventing the impurities from being deposited at the bottom of the quenching tank 1 and contaminating the coolant. This can affect the quenching effect of the workpiece and the detection of the coolant after quenching by the circulating pipe 22.

[0056] During the reciprocating movement of the closing plate 35, the scraper 39 passes through the scraper 39, and the scraper 39 scrapes the surface of the closing plate 35 to clean impurities, thereby reducing the workload of cleaning the quenching pool 1, shortening the quenching work interval time, and improving the quenching efficiency; and, when the closing plate 35 reciprocates, the closing plate 35 drives the scraper 4 to move, and the scraper 4 scrapes up the impurities deposited on the bottom of the quenching pool 1. Since the impurities scraped and lifted here are close to the suction groove 34, these impurities are sucked away while being scraped, avoiding scattering, thereby improving the impurity removal effect, thereby improving the cleanliness of the coolant, and then improving the detection effect; and, moreover, the top of the scraper 4 can also be connected to the sub-plate through a spring sliding connection. After the float box 21 contacts the sub-plate, the lifting platform 25 rises and falls a short distance, so that the scraper 4 drives the sub-plate to scrape the bottom of the float box 21, cleaning the impurities attached to the bottom of the float box 21, and the cleaned impurities flow into the suction groove 34 with the coolant, thereby improving the cleanliness and reducing the influence of impurities on the detection work.

[0062] Specific working process: The rotating pipe 14 sucks the coolant located at the upper part of the liquid outlet pipe 13, and the quenching pool 1 replenishes the coolant into the liquid outlet pipe 13 through the extension pipe 33, so that the coolant in the liquid outlet pipe 13 forms a flow path from bottom to top. During the coolant flow process, the rotating plate 16 drives the coolant to rotate, and the impurities in the coolant are affected by the centrifugal effect and move into the deep part of the annular groove 41 to contact the sponge layer;

[0063] Furthermore, the annular groove 41 divides the interior of the liquid outlet pipe 13 into multiple centrifugal chambers. Each chamber can be regarded as a small centrifugal unit, causing the coolant to undergo multiple centrifugal effects during the flow process, thereby extending the separation path between impurities and liquid and improving separation efficiency. Furthermore, the presence of the annular groove 41 disrupts the laminar flow state of the fluid and intensifies the turbulence of the coolant, making it easier for impurity particles to break away from the fluid streamline and be thrown toward the groove wall. At the same time, the centrifugal force causes the impurities to settle near the groove wall, preventing them from being re-suspended due to fluid disturbance.

[0064] Moreover, high-density metal particles such as nickel-based alloy debris tend to deposit on the tank wall under the action of centrifugal force; low-density impurities such as oil stains and bubbles tend to gather in the center of the fluid. Workers can set oil drainage components such as oil-absorbing sponges in the rotating tube 14 for further removal. One liquid outlet pipe 13 can achieve graded separation of multiple types of impurities, which helps to improve the detection effect of the circulation pipe 22. It can also cooperate with the detection function of the circulation pipe 22 on the coolant, making it easier for workers to understand the usage status of the coolant, and to formulate quenching process adjustments for nickel-based alloy workpieces based on the usage status, thereby improving the quenching effect.

[0065] In addition, the annular groove 41 may adopt a streamlined profile, such as an arc-shaped groove wall, which can enhance the centrifugal effect while reducing the flow resistance of the coolant, making it easier to achieve the needs of online continuous processing and improving practicality;

[0066] After the impurities come into contact with the sponge layer, they are continuously affected by the centrifugal force, and the sponge layer collects the impurities on the surface, and due to the friction force on the sponge surface, the impurities can be prevented from being affected by the flow and moving up; when too many impurities adhere to one side of the sponge layer, the electric push rod 46 drives the lifting ring 45 to descend, and the conical surface of the lifting ring 45 contacts and squeezes the linkage plate 44, so that the linkage plate 44 is guided by the conical surface and moves out of the rotating plate 16, and the linkage plate 44 contacts the cleaning plate 43 and drives the cleaning plate 43 to rotate around the annular groove 41. While the cleaning plate 43 scrapes the inner wall of the annular groove 41, it passes through and drives the rotating shaft 42 to rotate through friction, and the rotating shaft 42 drives the sponge layer to rotate, converting the sponge toward the surface inside the liquid outlet pipe 13, so that the sponge layer can collect impurities in turn, thereby increasing the amount of impurities collected and improving the collection efficiency; when the electric push rod 46 replaces the lifting ring 45 to rise, the lifting ring 45 moves away from the linkage plate 44, and the linkage plate 44 is affected by the spring to retract into the inside of the rotating plate 16, and the cleaning plate 43 gradually stops;

[0067] After a long period of filtration, impurities need to be discharged. The worker pulls up the sealing sleeve 48, and the sealing sleeve 48 rises to the connecting groove 49 and overlaps with the annular groove 41, so that the annular groove 41 is connected to the sampling groove 47. The lifting ring 45 descends and drives the cleaning plate 43 to rotate through the linkage plate 44. The cleaning plate 43 drives the rotating shaft 42 to rotate. The coolant in the liquid outlet pipe 13 passes through the sponge layer and flows into the sampling groove 47. The impurities collected on the surface of the sponge layer are filled into the sampling groove 47, completing the purpose of cleaning the sponge layer and discharging impurities, thereby improving the continuous working capacity; and the circulation pipe 22 is used for online monitoring, and its monitoring capability is limited. Workers need to take samples regularly to detect the impurity components in the coolant and detect the impurities filtered out in the quenching liquid, which can directly reflect the status of the quenching process and provide key basis for process optimization, equipment maintenance and quality control, thereby improving the quenching effect.

[0068] Example 4:

[0069] On the basis of the third embodiment, scrapers 5 are evenly arranged in the annular groove 41, and the scrapers 5 contact the side of the sponge layer away from the center of the liquid outlet pipe 13;

[0070] Specific working process: when the rotating shaft 42 drives the sponge layer to rotate through the connection between the annular groove 41 and the sampling groove 47, the scraper 5 scrapes the surface of the sponge layer, scraping the impurities collected on the surface of the sponge layer into the inside of the collecting groove, and at the same time, squeezes the sponge layer to squeeze out the oil and other flocculent impurities collected inside the sponge layer, thereby improving the cleaning efficiency and increasing the amount of impurities collected, making sampling and testing convenient; and, when the coolant passes through the annular groove 41, it is blocked by the sponge layer and the flow rate is slow, thereby reducing the amount of coolant entering the sampling groove 47 and avoiding affecting the sampling work.
