Description

Technical Field

[0001] The present invention relates to the technical field of forging heat treatment, and specifically discloses a heat treatment cooling device for stainless steel forgings used in nuclear power. Background Art

[0002] Austenitic steel is a stainless steel material with excellent corrosion resistance and high-temperature strength, and is widely used in the nuclear power field. The manufacturing process of nuclear power austenitic stainless steel forgings mainly includes two links: forging and heat treatment. After forging, heat treatment process is also required to further improve the performance and quality of the forgings. Generally speaking, the heat treatment process is divided into two types: (1) Solution treatment, heating the forging to a certain temperature to make it reach a uniform tissue state, and then rapidly cooling; (2) Quenching treatment, heating the forging to a certain temperature and then rapidly cooling to further improve its hardness and strength. Therefore, the cooling device is indispensable in the heat treatment process of nuclear power stainless steel forgings. The cooling device is divided into three cooling methods according to different cooling speeds: air cooling, pit cooling, and furnace cooling. The cooling speed in the air is faster than that in the sand pit and in the furnace.

[0003] Combined with carbon tool steel, alloy tool steel, bearing steel and other steel grades with relatively high carbon content, if slow cooling is adopted after forging, network carbide will precipitate at the grain boundary, which will seriously affect the service performance of the forgings. Therefore, such forgings need to be air-cooled, blown or sprayed with rapid cooling first after forging, and then the forgings are placed in a sand pit or furnace for slow cooling. Austenitic steel is a steel grade without phase change, and there is no phase change during the post-forging cooling process, so air cooling treatment can be directly adopted.

The heat treatment cooling device provided by the present invention can solve the problem that the workpiece after heat treatment in the background art is easily affected by natural factors during the cooling process, resulting in a reduction in performance.

[0005] Based on the above retrieval and combined with the existing technology, it is found that in the prior art, when air cooling treatment is carried out on the heat-treated stainless steel forgings, the air flow blows downward from the upper direction of the forging, and the air flow will contact the top of the forging for the first time. However, the bottom and side surfaces of the forging can only contact the air flow after the forging rotates. As a result, the entire surface of the forging cannot be evenly contacted with the air flow at the first time, and the forging will be deformed due to different temperature differences, resulting in poor cooling effect of the entire heat treatment cooling device. Therefore, a heat treatment cooling device for stainless steel forgings used in nuclear power is proposed to improve the above problems. Summary of the Invention

[0036] The first implementation mode: The present invention provides a heat treatment cooling device for stainless steel forgings used in nuclear power. Please refer to Figures 1 - 10, including a machine body 7. An inner cavity 17 is provided inside the machine body 7, and a ventilation opening 24 is provided at the middle position of the top of the inner cavity 17. An air-cooling assembly is provided at the top of the ventilation opening 24. A water storage tank 5 is fixedly installed at the bottom of the machine body 7, and a support truss 1 is fixedly installed at the bottom of the water storage tank 5. The air-cooling assembly includes an air-cooling unit 2 fixedly installed on one side of the top of the support truss 1. The exhaust end of the air-cooling unit 2 is fixedly installed with a ventilation duct 13. A flow guide cover 11 is fixedly installed between the exhaust end of the ventilation duct 13 and the top of the ventilation opening 24. A flow equalizing plate 33 is fixedly installed on the inner wall of the flow guide cover 11. An inlet and outlet 22 communicating with the inner cavity 17 is provided at one end of the machine body 7, and a support assembly 8 for supporting a forging body 27 is inserted inside the inlet and outlet 22. A displacement assembly for driving the support assembly 8 to move out and move in is installed on the machine body 7. First shunt plates 16, second shunt plates 29, third shunt plates 31, and fourth shunt plates 32 are fixedly installed on the inner walls at both ends of the inner cavity 17 from outside to inside in sequence. The gaps between the first shunt plates 16, second shunt plates 29, third shunt plates 31, and fourth shunt plates 32 are provided as air flow shunt channels, and the air flow shunt channels communicate with the ventilation opening 24. The first shunt plates 16, second shunt plates 29, third shunt plates 31, and fourth shunt plates 32 are all designed as irregular arcs, and the bottom ends of the first shunt plates 16, second shunt plates 29, third shunt plates 31, and fourth shunt plates 32 are distributed from top to bottom along both sides of the forging body 27. The top ends of the first shunt plates 16, second shunt plates 29, third shunt plates 31, and fourth shunt plates 32 are flush. A diversion groove 25 is provided inside the machine body 7. The diversion groove 25 surrounds the inner cavity 17. Air guide openings 30 communicating with the inner cavity 17 are provided at the top of both inner walls of the diversion groove 25. Oblique grooves 18 are provided at both corners of the top of the machine body 7, and air exhaust openings 21 communicating with the bottom of the oblique grooves 18 are provided on both inner walls of the diversion groove 25. Oblique seats 28 are fixedly installed on both inner walls of the diversion groove 25 near the air exhaust openings 21 at equal distances. By using the above air-cooling unit 2, direct air-cooling operation can be carried out on the nuclear power stainless steel forging, so that the cooling speed of the stainless steel forging is faster. And by using the partitioning effects of the above first shunt plates 16, second shunt plates 29, third shunt plates 31, and fourth shunt plates 32, the cold air flow blown into the inner cavity 17 by the air-cooling unit 2 is circulated along multiple air flow channels, so that multiple cold air flows can agitate around the stainless steel forging, enabling the nuclear power stainless steel forging to come into contact with the cold air flow in the first time all around. This replaces the existing cooling method of directly blowing the cold air flow on the top of the stainless steel forging, so that the surface of the stainless steel forging can come into contact with the air flow evenly in the first time, avoiding the problem of deformation of the stainless steel forging caused by the temperature difference during contact, and improving the cooling effect of the entire heat treatment cooling equipment.

[0037] In the present invention, heat dissipation grooves 20 which are equidistantly communicated with the inside of the diversion groove 25 are formed in the inner walls of the two inclined grooves 18, and heat dissipation fins 12 are fixedly installed on the inner walls of the heat dissipation grooves 20. A return port 26 is formed at the middle position of the top of the water storage tank 5 and at the middle position of the bottom of the diversion groove 25. As Figure 1 , Figure 5 , Figure 6 shown, since the temperature outside the body 7 is lower than the temperature inside, water molecules in the discharged air flow condense into a liquid state on the inner wall of the diversion groove 25, and with the function of the heat dissipation fins 12, the condensation speed of the water molecules is faster, so that the condensed water can fall to the bottom of the diversion groove 25 and enter the water storage tank 5 along the return port 26 for collection, enabling the entire cooling device to achieve the performance of recovering condensed water.

[0038] In the present invention, the support assembly 8 includes a sealing cover plate 801 that is hermetically clamped to the inner wall of the inlet and outlet 22, and two connecting plates 802 are fixed to both ends of the outer wall of one side of the sealing cover plate 801. Two support rails 23 are fixedly installed on the inner wall of the inner cavity 17. Slide seats 804 that are slidably arranged in the support rails 23 are fixedly installed on one side of each connecting plate 802. One end of each connecting plate 802 is fixed with the same limiting baffle 803. Two support shafts are rotatably connected between one side of the limiting baffle 803 and one side of the sealing cover plate 801. Support gears 805 are fixedly installed on both support shafts. The forging body 27 is placed on the two support gears 805. A rotating mechanism is arranged at one end of the two support shafts. The rotating mechanism includes drive wheels fixedly installed at one end of the two support shafts, and a drive belt 807 is connected between the two drive wheels. A rotating motor 806 for driving the support shafts and the drive belt 807 to rotate is fixedly installed on the other side of the sealing cover plate 801. As Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 shown, by adopting the above support assembly 8 and rotating mechanism, the forging body 27 can be placed on the two support gears 805, facilitating the support of the forging body 27, and the rotating motor 806 in the rotating mechanism drives the support shafts, the drive belt 807 and the support gears 805 to rotate, so as to drive the forging body 27 to rotate slowly under the rotational propulsion of the support gears 805, enabling the surface of the forging body 27 to come into contact with the cold air flow more fully, and further improving the cooling effect and cooling speed of the entire cooling device.

[0039] In the present invention, the displacement assembly includes mounting seats 19 fixedly installed at one end of the outer walls on both sides of the body 7, and hydraulic cylinders 10 are fixedly installed on one side of each mounting seat 19. A movable plate 9 is fixedly installed between the piston ends of the hydraulic cylinders 10 and one side of the sealing cover plate 801. As Figure 1 , Figure 3As shown, by using the above displacement component, the movable plate 9 and the sealing cover plate 801 can be driven to move back and forth under the telescopic action of the hydraulic cylinder 10, which is convenient for driving the support component 8 and the stainless steel forging to enter and exit the machine body 7, realizing the performance of convenient feeding and discharging.

[0040] In the present invention, a control box 3 is fixedly installed on one side of the top of the support truss 1, and a controller is arranged in the control box 3. The controller is electrically connected to the air-cooling unit 2 and the rotating motor 806, as Figure 1 and Figure 2 shown. By using the above controller, the operation of the air-cooling unit 2 and the rotating motor 806 can be controlled, which is convenient for controlling the entire cooling equipment to work.

[0041] In summary, the working principle of the present invention is as follows: During work, the staff places the forging body 27 between the two support gears 805 on the support component 8, and uses the hydraulic cylinder 10 in the displacement component to adjust the positions of the movable plate 9 and the support component 8, so that the sealing cover plate 801 fits into the inlet and outlet 22, and the forging body 27 also enters the inner cavity 17. At this time, the staff starts the air-cooling unit 2 through the controller, and the cold air flow generated by the air-cooling unit 2 flows along the ventilation duct 13, and the cold air flow is made to flow evenly by the flow equalizing plate 33 in the air deflector 11 and then enters the inner cavity 17 along the ventilation port 24. Thus, the air-cooling operation of the nuclear power stainless steel forging is directly carried out by the air-cooling unit 2. When the cold air flow enters the inner cavity 17, the cold air flow is made to flow along multiple air flow channels by the partitioning action of the first flow dividing plate 16, the second flow dividing plate 29, the third flow dividing plate 31 and the fourth flow dividing plate 32, so that multiple cold air flows can agitate around the forging body 27, so that the periphery of the nuclear power stainless steel forging can come into contact with the cold air flow at the first time. Then, the used cold air flow is discharged along the diversion groove 25, the air guide port 30 and the air outlet 21. And when the air flow is discharged, since the temperature outside the machine body 7 is lower than the internal temperature, the water molecules in the discharged air flow condense into a liquid state on the inner wall of the diversion groove 25, and with the cooperation of the heat dissipation fins 12, the condensation speed of the water molecules is faster, so that the condensed water can fall to the bottom of the diversion groove 25 and enter the water storage tank 5 along the return port 26 for collection, so that the entire cooling equipment can realize the recovery of the condensed water; and during the air-cooling process, the staff can control the operation of the rotating motor 806 in the rotating mechanism through the controller, and drive the support shaft, the transmission belt 807 and the support gear 805 to rotate by the rotation mode of the rotating motor 806, so as to drive the forging body 27 to rotate slowly under the rotating propulsion action of the support gear 805, so that the surface of the stainless steel forging can come into contact with the cold air flow more fully.

[0042] The second implementation mode: Referring to Figure 1 、 Figure 2 and Figure 3, on the basis of Embodiment 1, the following structure is added in this embodiment, so that this application has the function of recycling condensate water. The specific settings are as follows: A condensate water return assembly is provided between the storage water tank 5 and the air-cooled unit 2. The condensate water return assembly includes an installation port opened on one side of the storage water tank 5, and a liquid level sensor 6 is fixedly installed on the inner wall of the installation port. A water pump 4 is fixedly installed on the top side of the support truss 1 close to the storage water tank 5. The water pump 4, the liquid level sensor 6 and the controller are electrically connected. The water inlet end of the water pump 4 is fixedly installed with a water suction pipe 15 inserted into the storage water tank 5. The water drainage end of the water pump 4 and the water inlet end of the air-cooled unit 2 are fixedly installed with a return pipe 14. By using the above condensate water return assembly, the liquid level in the storage water tank 5 can be detected by the liquid level sensor 6. When the liquid level in the storage water tank 5 reaches a certain height, the liquid level signal is transmitted to the controller, and the water pump 4 is controlled to work, so as to introduce the return water in the storage water tank 5 into the air-cooled unit 2, realizing the performance of recycling condensate water.
