Description

Technical Field

[0001] The present application relates to the field of alloy smelting and processing, and in particular to an integrated processing technology for high-temperature resistant nickel-based alloys. Background Art

[0002] GH4080A alloy has high heat resistance, high strength and high deformation resistance at high temperatures, which increases the difficulty of forging. To facilitate subsequent forging processing, it is smelted in a large furnace and the alloy liquid is introduced into a smaller mold to form smaller alloy blocks, which reduces the difficulty of subsequent forging processing. However, large furnaces process a large amount of volume at one time, which is not conducive to the integrated manufacturing of small-volume alloys. At the same time, the metal raw materials and alloy liquid need to be transferred in multiple containers in a relatively exposed environment, which involves many processing steps and is difficult to process. In particular, the alloy and alloy liquid are easily exposed and oxidized, which affects the quality of the finished product.

[0003] By processing the nickel-based alloy raw materials into particles or powder state and placing them into a crucible for heating, small-batch targeted processing can be achieved to meet the smelting, processing and manufacturing of small-volume alloys. The overall processing and manufacturing equipment is small in size and can integrate the material placement, smelting, molding, cooling and compression into an integrated processing equipment to achieve integrated processing.

[0004] However, elements such as Cr and Al in nickel-based alloys are easily oxidized, and the large surface area of ​​particles or powders will intensify oxidation (especially in an air atmosphere), forming oxide slag that affects the purity of the alloy. Since traditional crucible heating and insulation need to be carried out in a relatively open environment, the gas protection atmosphere is difficult to effectively adjust and control, causing oxidation of some alloy liquids; at the same time, the traditional use of crucibles to melt and insulate the alloy liquid requires manual or automated equipment to transfer and dump the crucible. Traditional processing equipment and processing technology have low operating efficiency, especially for high-temperature resistant nickel-based alloys. The temperature around the processing equipment is high, and some sensing probes and equipment cannot operate continuously for a long time. Summary of the Invention

[0005] In view of the above problems, an embodiment of the present application is proposed to provide an integrated processing technology for high-temperature resistant nickel-based alloys.

[0006] In response to the above problems, the present invention provides an integrated processing technology for high-temperature resistant nickel-based alloys. The invention simplifies the relevant structure, and the alloy processing is automatically carried out in a relatively closed small range, realizing efficient smelting and integrated processing of high-temperature resistant nickel-based alloys.

[0007] In order to solve the above problems, the technical solution adopted by the present invention is: A high-temperature resistant nickel-based alloy integrated processing technology comprises the following steps: S1, placing high-temperature resistant nickel-based alloy raw materials in a high-temperature resistant crucible according to a mass ratio, and heating to above the melting point of the high-temperature resistant nickel-based alloy to obtain an alloy liquid; S2, insulating the alloy liquid after being heated for a predetermined time, and stirring and mixing the alloy liquid during the insulation process, using a high-temperature resistant nickel-based alloy integrated processing equipment, the high-temperature resistant nickel-based alloy integrated processing equipment comprising an insulation device, an inclined insulation channel being provided inside the insulation device, and the alloy liquid being insulated through the insulation channel; driving the insulation channel to deflect and flip as a whole to achieve insulation stirring and insulation diversion of the alloy liquid in the insulation bin; S3, discharging the alloy liquid after insulation and flowing into a casting mold for casting and forming.

[0008] Preferably, the high-temperature resistant nickel-based alloy is in a granular or powdered state. Before use, the granules or powder are placed in an inert gas protection drying oven and dried at 100-150° C. for 2-4 hours.

[0009] Preferably, the insulation channel is composed of multiple insulation bins, which are cylindrical structures. Insulation covers are provided on both sides of the insulation bins, and guide ports are opened on the side walls of the insulation covers for the alloy to pass through. The guide ports on the left and right sides of the same insulation bin are located on opposite sides.

[0010] Preferably, when the guide port on the lower side is controlled to be at the lowest point, the guide port is located at the bottom to guide the molten alloy liquid, and the molten alloy liquid is guided to a lower insulation bin for storage and insulation.

[0011] Preferably, during the heat preservation and stirring process, the heat preservation channel is controlled to deflect back and forth within a small angle range as a whole, thereby driving the alloy liquid in the heat preservation chamber to oscillate back and forth at a predetermined position.

[0012] Preferably, during the heat preservation and diversion process, the heat preservation channel is controlled to deflect 180° as a whole, the heat preservation channel is controlled to flip as a whole, and the positions of the diversion ports on both sides of the heat preservation chamber are swapped.

[0013] Preferably, the casting mold is placed in a heat preservation device for preheating, and the casting mold is preheated to 190-400° C. A conveyor line is provided at the bottom of the heat preservation device to carry and transport the casting mold.

[0014] Preferably, a driving component is provided in the heat preservation device to control the deflection and rotation of the heat preservation channel, and the conveying line is electrically connected to the driving component.

[0015] Preferably, a pumping device and a valve group are provided in the conveying channel. The valve group is located on the side close to the heating device. During the insulation process, the valve group is controlled to be closed, and the pumping device pumps protective gas into the insulation channel. The protective gas flows toward the bottom of the insulation channel and finally flows out from the material guide pipe into the insulation device.

[0016] Preferably, the high temperature resistant crucible is a high purity graphite crucible, and the inner wall of the graphite crucible is provided with an anti-corrosion coating.

[0017] The beneficial effects of the present invention are: Compared with the existing technology, the insulation channel can replace the traditional crucible to perform insulation stirring and insulation diversion on the alloy liquid. The insulation stirring can promote the efficient mixing of various components in the alloy liquid. The insulation diversion can realize the automatic transfer of the alloy liquid. The alloy processing is carried out in a relatively closed small range, which reduces the difficulty of protective atmosphere protection and avoids the oxidation of the alloy. At the same time, there is no need to install stirring and diversion devices in a small space, which simplifies the relevant structure and realizes the efficient smelting integrated processing of high-temperature resistant nickel-based alloys.

DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] The composition of the nickel-based high-temperature resistant alloy GH4080A is as follows (by mass fraction): Cr is 18%-21%; Fe ≤ 1.5%; Mn ≤ 0.4%; Si ≤ 0.8%; P ≤ 0.02%; S ≤ 0.015%; Al is 1%-1.8%; Ti is 1.8%-2.7%; C is 0.04%-0.10%; Co ≤ 2.0%; B ≤ 0.008%; Cu ≤ 0.2%; the balance is Ni and unavoidable impurities; the melting point of the alloy is 1405 ° C, and the density is 8.15 g / cm 3 It is a precipitation-hardenable alloy with excellent high-temperature (maximum 815°C) tensile properties; it is suitable for manufacturing bolts; exhaust valves for diesel engines for ships and tanks and other parts.

[0026] Refer to the attached Figure 1 - Attachment Figure 5 A high-temperature resistant nickel-based alloy integrated processing technology is used to manufacture the above-mentioned high-temperature resistant nickel-based alloy, comprising the following steps: Step 1: Raw material selection; select high-temperature resistant nickel-based alloy raw materials according to the proportion. The raw materials are in small size and can be selected in granular or powder form. Store in a drying room with a temperature of 20-25°C and a humidity of ≤30%RH; before use, place the granules or powder in a vacuum drying oven, preferably in an inert gas protection drying oven, and dry at 100-150°C for 2-4 hours to remove moisture adsorbed by the raw materials and prevent the formation of pores during smelting.

[0027] Step 2: Heating and melting; the high-temperature resistant nickel-based alloy raw materials are proportioned according to mass. Taking into account the loss of some elements, the alloy ratio can be adjusted and increased according to production parameters; a high-temperature resistant crucible is selected to accommodate the above raw materials, and then the crucible and the above raw materials are heated to above the melting point of the high-temperature resistant nickel-based alloy.

[0028] The above-mentioned crucible is preferably a high-purity graphite crucible, and an anti-corrosion coating is provided on the inner wall of the graphite crucible. The above-mentioned anti-corrosion coating is preferably a zirconia coating. The melting point of zirconia is as high as 2715°C, which is far higher than the alloy melting temperature. Zirconia is an inert ceramic and has extremely low reactivity with active elements such as Cr, Mo, and Ti in the alloy, which can prevent the crucible material from being corroded by the melt and introducing impurities; at the same time, zirconia itself is a non-conductor. During batch melting, the crucible wall thickness is relatively thin (usually 5~10mm), which will not significantly shield the electromagnetic induction magnetic field. Heat can be induced by the alloy melt itself (or with auxiliary heating by a graphite crucible), meeting the energy transfer requirements of electromagnetic induction heating; and the zirconia layer has good thermal shock stability (not easy to crack when suddenly changing from room temperature to high temperature), which is suitable for rapid electromagnetic induction heating.

[0029] The crucible is baked in a vacuum or inert atmosphere (300-500°C, 1-2 hours) before use to remove moisture and volatile components in the crucible.

[0030] The above heating can be carried out by traditional heating means or by electromagnetic induction heating. The staff places the above crucible in the electromagnetic heating coil, and induction heats the graphite crucible and the alloy inside by electromagnetic induction heating. The melting point of graphite is higher than that of the above high-temperature resistant nickel-based alloy, and it can play an auxiliary heating role on the outside. During the heating process, the electromagnetic induction power supply is started, and the alloy is heated to above the melting point at a reasonable heating rate (such as 5-10℃ / min). The actual melting temperature needs to be 50-100℃ higher than the melting point, that is, 1455-1505℃. During the heating process, the temperature is monitored in real time by an infrared thermometer or thermocouple.

[0031] The pre-treated alloy particles / powder are evenly loaded into the crucible. The filling can be layered and vibrated moderately to ensure that the material is dense, which is conducive to heat transfer during electromagnetic induction heating.

[0032] Step 3: Insulation and mixing; Insulate the alloy liquid after heating for a predetermined time in step 2 for 15-30 minutes. Stir and mix the alloy liquid during the insulation process to promote uniform mixing of various internal components and ensure the quality of the finished product. The above operations are carried out in a special insulation area, isolated from the air under an inert gas atmosphere to avoid oxidation of internal components and the addition of impurities.

[0033] The above operation uses an integrated high-temperature resistant nickel-based alloy processing equipment, which includes a heating device 100 and an insulation device 200. The heating operation in step two can be achieved through the heating device 100. The heating device 100 and the insulation device 200 are connected through a conveying channel 110 to realize the transfer of alloy liquid.

[0034] The insulation device 200 as a whole is a relatively closed structure. An inclined insulation channel 210 is provided inside the insulation device 200. The alloy liquid is insulated through the insulation channel 210. Support components 220 are installed on both sides of the insulation device 200 to support the insulation channel 210 to maintain relative stability in the inclined state. The insulation channel 210 as a whole is a hollow columnar structure, which can store and orderly transfer the alloy liquid to achieve insulation and transportation of the alloy liquid. The insulation channel 210 can replace multiple crucibles to store and transport the alloy liquid. There is no need to set up corresponding handling structures and transfer structures. The above functions can be achieved through one insulation channel 210. At the same time, the insulation channel 210 is in a relatively closed state along the length direction, and the left and right sides of the insulation channel 210 are in an open state to allow the alloy liquid to pass through.

[0035] Specifically, the insulation channel 210 is composed of multiple insulation bins 500. The insulation bins 500 are cylindrical structures. Insulation covers 510 are provided on both sides of the insulation bins 500. The side walls of the insulation covers 510 are provided with guide ports 511 for the alloy to pass through. The guide ports 511 on the left and right sides of the same insulation bin 500 are located on opposite sides. By controlling the insulation bins 500 to rotate to different angles, the storage and diversion of the molten alloy liquid can be achieved.

[0036] Specifically, when the guide port 511 on the lower side is controlled to be at the lowest point, the guide port 511 can be located at the bottom to guide the molten alloy liquid, and the molten alloy liquid is guided to a lower insulation bin 500 for storage and insulation.

[0037] The guide port 511 on the lower side is controlled to be at the highest point. The guide port 511 can be at the topmost position. At this time, the insulation bin 500 and the inner wall of the insulation cover 510 form a relatively closed structure. The insulation bin 500 can form an insulation chamber 5001 to store the alloy liquid, preventing the alloy liquid from continuing to flow toward the next insulation bin 500, thereby realizing storage, heating and insulation of the insulation bin 500.

[0038] The flow guide ports 511 of two adjacent heat-insulating bins 500 are interconnected, allowing the molten alloy liquid to flow downward. The two adjacent heat-insulating bins 500 can form a large storage container, which can separate different batches of alloy liquid.

[0039] For example, there are four insulation bins 500 arranged adjacent to each other from top to bottom. When the alloy liquid in the first insulation bin 500 at the highest point flows to the second insulation bin 500 at the second highest point, the alloy liquid in the third insulation bin 500 simultaneously flows into the fourth insulation bin 500 for insulation storage; after the alloy liquid finishes flowing, the first insulation bin 500 and the third insulation bin 500 are in an empty state, preparing in advance for the subsequent inflow of alloy liquid.

[0040] Continuing the above operation, when the alloy liquid in the second insulation bin 500 flows into the third insulation bin 500, the alloy liquid in the fourth insulation bin 500 flows out into the mold for casting; at the same time, the newly heated alloy liquid can be put into the first insulation bin 500 for storage, and the above steps are repeated to control the orderly flow and insulation of the alloy liquid in multiple insulation bins 500. The alloy liquid can be stored and transported within a smaller size range, and it is only necessary to control the insulation bin 500 to be within the protection range of the inert gas, thereby avoiding the oxidation and introduction of impurities of the alloy liquid during the insulation and mixing process to the greatest extent; and the inner wall size of the insulation bin 500 is small, and there are only openings on both sides for the alloy liquid to pass through. The insulation bin 500 is controlled by inert gas to be in a slightly positive pressure state, which is relatively controllable and easy to adjust, with lower cost and more accurate control effect.

[0041] It should be noted that two adjacent insulation bins 500 are fixed to each other to form an integral insulation channel 210. The above description is based on four insulation bins 500 as an example. According to the needs of alloy insulation, the above insulation bins 500 can be selected in multiple numbers; the support assembly 220 is rotatably connected to the corresponding insulation bin 500, and can control the insulation channel 210 to rotate around its own axis as a whole. At the same time, a driving assembly 230 is provided in the insulation device 200, which can drive the insulation channel 210 to deflect and flip as a whole, thereby realizing stirring and diversion of the alloy liquid in the insulation bin 500.

[0042] During the insulation and stirring process, controlling the insulation channel 210 to deflect back and forth within a small angle as a whole can drive the alloy liquid in the insulation bin 500 to oscillate back and forth at a predetermined position without adding a separate stirring tool. By controlling the insulation channel 210 to deflect back and forth as a whole, oscillation and stirring can be achieved in multiple insulation bins 500, thereby promoting the mixing of various components in the alloy liquid during the insulation process and improving the quality of the finished alloy.

[0043] During the insulation and diversion process, the insulation channel 210 is controlled to deflect 180° as a whole, and the insulation channel 210 is controlled to flip over as a whole. At this time, the diversion ports 511 on both sides of the insulation bin 500 flip to the highest point position or the lowest point position, so as to realize the flipping and diversion of the alloy liquid after stirring, and the alloy liquid in the high-position insulation bin 500 flows into the adjacent low-position insulation bin 500 for re-storage and insulation stirring; after the insulation channel 210 flips 180° as a whole, the insulation channel 210 continues to be controlled to repeatedly deflect at a small angle. During the repeated deflection process, the alloy liquid can pass through the small-sized diversion port 511 during the reciprocating deflection process, and the inner wall of the diversion port 511 can act as a stirring tool, exerting a tangential force on the alloy liquid in the flow process, further promoting the stirring and mixing inside the alloy liquid, and improving the quality of the final finished alloy.

[0044] In the above manner, the alloy liquid can flow in sequence and be kept warm and stirred in the insulation channel 210, and different batches of alloy liquid flow in an orderly manner toward a lower position. The alloy liquid in the insulation bin 500 at the bottom is discharged from the guide pipe 211 after turning 180°, and is cast into the corresponding casting mold 300 to achieve calibration; the guide pipe 211 here is in a connected state with the guide port 511 on the outside of the bottom insulation bin 500, thereby achieving the diversion of the alloy liquid.

[0045] Step 4: alloy liquid casting; the alloy liquid after insulation is finally discharged and flows into the casting mold 300 for casting and molding. The casting mold 300 here is set in the insulation device 200, and the insulation device 200 is also in a protective atmosphere to avoid the introduction of impurities during the casting process; the casting mold 300 is preheated to 190-400℃ to reduce the temperature difference between the alloy liquid and the mold, avoid cold shut and insufficient pouring defects, and reduce thermal stress at the same time, and apply a release agent on the surface of the mold cavity, such as graphite emulsion, to facilitate subsequent demolding; control the casting speed (such as 0.5-1.5m / s, adjusted according to the size of the mold cavity) to ensure that the alloy liquid fills the cavity smoothly to avoid splashing and air being drawn in.

[0046] The casting mold 300 is placed in the insulation device 200 for preheating. Multiple casting molds 300 are arranged along the length direction of the insulation channel 210. A conveyor line 400 is provided at the bottom of the insulation device 200 to carry and transport the casting mold 300. Multiple casting molds 300 are arranged horizontally, and the insulation channel 210 is arranged inclined. During the movement, the casting mold 300 gradually approaches the insulation channel 210 to achieve preheating and temperature rise.

[0047] At the same time, the conveying line 400 here is electrically connected to the driving component 230. After the driving component 230 controls the insulation channel 210 to deflect 180° for the first time, the alloy liquid flows into the insulation bin 500 at the bottom for the last storage and insulation. At the same time, the corresponding casting mold 300 is controlled by the conveying line 400 to move to the bottom of the guide pipe 211 to prepare for casting; after the driving component 230 controls the insulation channel 210 to deflect 180° for the second time, the alloy liquid flows out from the guide pipe 211, and the alloy liquid flows out directly into the casting port at the upper end of the casting mold 300 to realize the casting of the alloy liquid once. The above steps are repeated subsequently to realize the continuous casting of multiple groups of alloy liquid.

[0048] Finally, it should be noted that a pumping device and a valve group are provided in the conveying channel 110. The valve group is located on the side close to the heating device 100. During the insulation process, the valve group is controlled to be closed, and the first side of the insulation channel 210 is controlled to be in a relatively closed state. The protective gas is pumped into the insulation channel 210 through the pumping device. Since the outer side is in the state of the valve group being closed, the protective gas can flow toward the bottom of the insulation channel 210, and finally flow out from the guide pipe 211 into the insulation device 200. The protective gas can fill the insulation channel 210 to avoid insulation. The alloy liquid is oxidized during the warming process, and during the casting process, the alloy liquid and the protective gas flow out synchronously, the alloy liquid can be cast in a protective atmosphere, and the oxidation of the alloy liquid during the casting process is avoided to the greatest extent; and the protective gas is directly discharged into the conveying line 400, the overall sealing of the conveying line 400 is good, the protective gas can be retained in the conveying line 400, especially on the side close to the guide tube 211, to achieve overall protection on the outermost side. Through the above method, the alloy liquid can be controlled to be processed in a protective atmosphere to the greatest extent, and alloy oxidation can be avoided.

[0049] It should also be noted that the insulation channel 210 and the conveying channel 110 are connected by a rotating seal, which can ensure that the alloy liquid is normally delivered to the first insulation bin 500 at the highest position. During the operation, electromagnetic induction heating is first realized to heat the alloy to a molten state. The alloy liquid in the graphite crucible can be manually delivered to the conveying channel 110. The conveying channel 110 is also arranged at an angle. The alloy liquid inside can automatically flow into the first insulation bin 500 under the action of gravity for subsequent insulation stirring and diversion. Subsequent operations are carried out automatically without manual participation, which greatly improves the efficiency of alloy integrated processing.

It is certainly within the scope of protection of the present invention for those skilled in the art to apply the concept of the present invention to the production of other alloys without departing from the technical solution of the present invention.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
