[0002] The high-temperature alloy bar roughing forming process optimizes the material structure and enhances the mechanical properties by precisely controlling the heating temperature and deformation parameters. This method not only effectively improves the quality of forgings, but also significantly improves production efficiency by reducing the number of heating times and processes. As one of the core technologies of precision forging, it is widely used in the production of high-temperature alloy forgings with strict requirements on material properties, ensuring that the final product meets the stringent standards of high-end manufacturing and promoting the progress and development of industrial technology.

[0003] However, the conventional high-temperature alloy bar roughing forming method still has the following problems: insufficient heat treatment uniformity: uneven heating may cause local overheating or overcooling of the material, affecting the final forming quality; cracks and defects: under high temperature conditions, the material is prone to cracks or surface defects, especially when the heating temperature and forming pressure are not properly controlled; tool wear: high-temperature alloys cause greater wear on molds and tools, and molds need to be replaced or repaired frequently; process complexity: precise control of heating, forming and cooling processes is relatively complicated, which can easily lead to operational difficulties and inconsistencies; high energy consumption: high-temperature heating and treatment processes consume a lot of energy, which increases production costs. It is urgent to improve the current forming methods to address the above problems. Summary of the invention

The material drying includes placing the cleaned alloy rod blank in a drying furnace, setting the temperature to 100-120°C, the drying time is 30 minutes, and ensuring that there is enough space between the rod blanks to avoid uneven drying caused by mutual contact. The material preheating includes heating the alloy rod blank to 400°C in a preheating furnace and maintaining it for 1 hour to reduce the impact of temperature difference on subsequent heating.

[0014] As a further technical solution of the present invention, the selected heating furnace selects to use a resistance furnace or an induction furnace and uses argon protection.

[0015] As a further technical solution of the present invention, the controlled heating time needs to be based on the diameter of the rod blank and the thermal conductivity of the material, usually 1-2 hours, to ensure that the material reaches a uniform heating temperature. The controlled heating rate needs to gradually increase the temperature during the heating process to avoid thermal stress caused by excessive heating. The rate is set to 5-10°C / min and adjusted in time according to the material reaction.

[0016] As a further technical solution of the present invention, the initial upsetting needs to use a high-pressure cylinder to apply pressure, and the pressure is set to 1800Mpa to ensure initial forming.

The controlling of the forming speed includes setting the forming speed to 0.7mm / s to ensure that the material maintains good fluidity during the deformation process, and monitoring the forming process in real time to adjust the speed to maintain stable deformation.

[0017] As a further technical solution of the present invention, the control of the mold temperature includes heating the mold to 250°C to avoid adhesion or wear caused by overcooling of the mold during high-temperature forming, regularly checking the mold temperature to ensure that the mold maintains a stable working temperature during the forming process, and the selected mold material needs to be H13 high-chromium steel, and the mold is regularly inspected and maintained to prevent wear and deformation from affecting the forming quality.

[0018] As a further technical solution of the present invention, the selected cooling method includes placing the upsetting alloy rod blank in a cooling furnace, gradually reducing the furnace temperature to room temperature, with a cooling rate of 5°C / h, and wrapping the rod blank with an insulating material and then slowly cooling it. The insulating material is selected as ceramic fiber. The cooling time needs to be set to 12-24 hours according to the size and material properties of the rod blank.

[0019] As a further technical solution of the present invention, the controlling annealing temperature includes controlling the furnace temperature to 1000°C and using a temperature control device to maintain stability. The controlling annealing time includes maintaining it for 4-6 hours according to the size of the rod blank to ensure uniform internal structure. The quenching includes selecting oil as a cooling medium and controlling the cooling rate to 5°C / s. The tempering requires setting the temperature of the tempering furnace to 600°C to reduce the brittleness after quenching, and maintaining the tempering temperature for 3 hours to achieve the desired physical properties.

[0020] As a further technical solution of the present invention, the dimension measurement includes precise measurement using a laser measuring instrument or a three-dimensional coordinate measuring machine, and it is necessary to check whether the diameter, length and shape of the rod blank meet the design tolerance. The surface inspection includes using ultrasonic flaw detection to check surface defects, and repairing or reprocessing the defects found to ensure the integrity of the final product.

[0021] As a further technical solution of the present invention, the hardness test includes using a Brinell hardness tester to perform a hardness test, and selecting multiple points for testing to ensure that the hardness of the material is uniform, and the hardness range is controlled to be HB 200-220. The microstructure inspection includes using a metallographic microscope to observe the microstructure of the material, and inspecting the grain structure, phase distribution and possible inclusions to ensure that the material standards are met and the grain size is controlled to be ≤10μm.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The present invention effectively removes the oxide layer and impurities on the surface of the rod blank through refined material processing steps, including pickling, drying and preheating, ensuring the purity and drying uniformity of the material. At the same time, preheating reduces the influence of temperature differences in the subsequent heating process, laying a solid foundation for high-quality forming. In the heating process, a resistance furnace or an induction furnace combined with argon protection is used to ensure the purity and uniformity of the heating process. Reasonable heating temperatures and times are set for different alloys to avoid local overheating or overcooling and optimize the microstructure of the material. In addition, the gradually increased heating rate and real-time monitoring and adjustment further reduce thermal stress and protect the integrity of the material. This series of heating control measures not only improves the quality of forgings, but also reduces energy consumption and costs in the production process, with significant economic benefits.

[0024] 2. The present invention ensures the stability and accuracy of the rod blank during the deformation process and avoids excessive deformation and internal defects by combining high-pressure initial upsetting with subsequent upsetting with gradual pressure reduction, and precisely controlling the forming speed and mold temperature. H13 high-chromium steel is selected as the mold material, and regular inspection and maintenance are carried out to effectively extend the service life of the mold and reduce the impact of tool wear on the forming quality. In the cooling stage, a slow cooling method of gradual cooling and wrapping with insulation materials is adopted to effectively prevent thermal stress and deformation caused by excessive temperature difference and optimize the organization and performance of the material. Subsequent annealing, quenching and tempering treatments further refine the grain structure, improve the strength, toughness and comprehensive performance of the material, and ensure that the forgings meet the stringent standards of the high-end manufacturing industry.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, in an embodiment of the present invention, a method for upsetting a high-temperature alloy bar blank based on a high-temperature resistant medium comprises the following steps:

[0034] S1: Material handling;

[0035] S2: Material heating;

[0036] S3: upsetting forming;

[0037] S4: Cooling;

[0038] S5: post-processing;

[0039] S6: Inspection and quality control;

[0040] The material processing includes material cleaning, material drying, and material preheating. The material heating includes selecting a heating furnace, controlling the heating temperature, controlling the heating time, and controlling the heating rate. The upsetting forming includes initial upsetting, subsequent upsetting, controlling the forming speed, controlling the mold temperature, and selecting the mold material. The cooling includes selecting a cooling method and controlling the cooling time. The post-processing includes controlling the annealing temperature, controlling the annealing time, quenching, and tempering. The inspection and quality control include dimensional measurement, surface inspection, hardness testing, and microstructure inspection.

[0041] Through fine material processing and heating control, the purity and uniform heating of the billet are ensured; the optimized upsetting process and die design ensure the precision and stability of the forming; reasonable cooling and post-processing improve the organization and performance of the material. This method effectively reduces production defects, improves the product qualification rate, and meets the high-quality requirements of high-temperature alloy forgings in the high-end manufacturing industry.

[0042] Preferably, the material cleaning includes using a pickling solution to clean the alloy bar blank to remove the surface oxide layer and impurities, the pickling solution uses a mixed solution of sulfuric acid and hydrofluoric acid, and the sulfuric acid concentration is 8%, the hydrofluoric acid concentration is 3%, the immersion time is 20 minutes, and the cleaning method uses a high-pressure water gun with a pressure of 5-7Mpa. The material drying includes placing the cleaned alloy bar blank in a drying furnace, setting the temperature to 100-120°C, the drying time is 30 minutes, and ensuring that there is enough space between the bar blanks to avoid uneven drying caused by contact with each other. The material preheating includes heating the alloy bar blank to 400°C in a preheating furnace and maintaining it for 1 hour to reduce the impact of temperature difference on subsequent heating.

[0043] The above-mentioned material cleaning, drying and preheating steps significantly improve the quality of the pre-forming preparation of high-temperature alloy billets. Pickling effectively removes the surface oxide layer and impurities, and high-pressure water gun flushing enhances the cleanliness; the drying furnace ensures uniform and rapid dehydration to avoid uneven drying; preheating effectively reduces the temperature difference between the inside and outside of the billet, laying a good foundation for the subsequent heating process. This series of pretreatment measures significantly improves the purity and uniformity of the formed parts, laying a solid foundation for the production of high-quality high-temperature alloy forgings.

[0044] Preferably, the selected heating furnace is a resistance furnace or an induction furnace, and is protected by argon gas. The controlled heating temperature needs to be set separately for different alloys, where the nickel-based high-temperature alloy needs to be set to 1100-1200°C, and the cobalt-based high-temperature alloy needs to be set to 1150-1250°C.

[0045] Selecting a resistance furnace or induction furnace and using argon protection for heating ensures the purity and uniformity of the high-temperature alloy billet during the heating process. Setting appropriate heating temperatures for different alloys, such as 1100-1200℃ for nickel-based alloys and 1150-1250℃ for cobalt-based alloys, effectively avoids overheating or overburning, while optimizing the microstructure of the alloy, providing an ideal material state for subsequent upsetting. This precise temperature control strategy significantly improves the quality and performance of high-temperature alloy forgings.

[0046] Preferably, the controlled heating time is based on the diameter of the rod blank and the thermal conductivity of the material, usually 1-2 hours, to ensure that the material reaches a uniform heating temperature. The controlled heating rate is required to gradually increase the temperature during the heating process to avoid thermal stress caused by too fast heating. The rate is set to 5-10°C / min and adjusted in time according to the material reaction.

[0047] By precisely controlling the heating time and heating rate, the uniformity and stability of the high-temperature alloy billet during the heating process are ensured. Reasonable heating time settings, based on the billet diameter and material thermal conductivity, ensure that the material reaches the target temperature fully and evenly. The gradually increased heating rate, combined with timely adjustments in combination with material reactions, effectively avoids the thermal stress problem caused by over-rapid heating. This series of heating control measures creates an ideal material state for subsequent upsetting and improves the overall quality and performance of the forging.

[0048] Preferably, the initial upsetting needs to use a high-pressure cylinder to apply pressure, and the pressure is set to 1800Mpa to ensure initial forming. The subsequent upsetting needs to gradually reduce the pressure to 1200Mpa to complete precise forming and avoid excessive deformation of the material. The controlling of the forming speed includes setting the forming speed to 0.7mm / s to ensure that the material maintains good fluidity during the deformation process, and monitoring the forming process in real time, and adjusting the speed to maintain stable deformation.

[0049] The upsetting process of high-temperature alloy billets can be optimized by precisely controlling the pressure and forming speed of the initial and subsequent upsetting. The high-pressure initial upsetting ensures the stability of the initial forming, while the subsequent gradual pressure reduction achieves precise forming and avoids excessive deformation of the material. The reasonable setting of the forming speed and real-time monitoring and adjustment ensure that the fluidity of the material is well maintained during the deformation process, and improves the dimensional accuracy and surface quality of the formed parts. This series of upsetting process measures significantly improves the overall quality and consistency of high-temperature alloy forgings.

[0050] Preferably, controlling the mold temperature includes heating the mold to 250°C to avoid adhesion or wear caused by overcooling of the mold during high-temperature forming, regularly checking the mold temperature to ensure that the mold maintains a stable operating temperature during the forming process, selecting the mold material to use H13 high-chromium steel, and regularly checking and maintaining the mold to prevent wear and deformation from affecting the forming quality.

[0051] Controlling the mold temperature to 250°C effectively prevents adhesion and wear problems caused by mold overcooling during high-temperature forming. At the same time, regular monitoring ensures the stability of mold temperature, providing a guarantee for high-quality forming. H13 high-chromium steel is selected as the mold material, which further extends the mold life with its excellent heat and wear resistance. Regular mold inspection and maintenance can detect and deal with wear and deformation in a timely manner, ensure the continuity of the forming process and the stability of the product, and improve overall production efficiency and product quality.

[0052] Preferably, the selected cooling method includes placing the alloy rod blank after upsetting in a cooling furnace, gradually reducing the furnace temperature to room temperature, with a cooling rate of 5°C / h, and slowly cooling the rod blank after wrapping it with an insulating material, wherein the insulating material is selected to be ceramic fiber, and the cooling time is set to 12-24 hours according to the size and material properties of the rod blank.

[0053] The gradual cooling method combined with the slow cooling strategy of ceramic fiber insulation materials effectively avoids the thermal stress and deformation of high-temperature alloy billets caused by excessive temperature differences during the cooling process. Reasonable cooling rate and time settings ensure the uniformity and stability of the material during the cooling process, which is conducive to optimizing the microstructure and performance of the material. This cooling method not only improves the dimensional accuracy and surface quality of the forgings, but also extends the service life of the material, providing high-quality high-temperature alloy forgings for the high-end manufacturing industry.

[0054] Preferably, the controlling of the annealing temperature includes controlling the furnace temperature to 1000°C and using a temperature control device to maintain stability, the controlling of the annealing time includes maintaining it for 4-6 hours according to the size of the billet to ensure uniform internal structure, the quenching includes selecting oil as a cooling medium and controlling the cooling rate to 5°C / s, the tempering requires setting the temperature of the tempering furnace to 600°C to reduce the brittleness after quenching, and maintaining the tempering temperature for 3 hours to achieve the desired physical properties.

[0055] By carefully controlling the annealing temperature and time, the uniformity of the internal structure of the high-temperature alloy billet is ensured, and the overall performance of the material is improved. During the quenching process, the rapid and stable cooling rate further optimizes the microstructure of the material. The subsequent tempering treatment not only effectively reduces the brittleness caused by quenching, but also achieves the required physical properties of the material by precisely controlling the tempering temperature and time. This series of post-processing processes significantly improves the strength, toughness and comprehensive performance of high-temperature alloy forgings, meeting the strict requirements of high-end manufacturing on material performance.

[0056] Preferably, the dimension measurement includes precise measurement using a laser measuring instrument or a three-dimensional coordinate measuring machine, and it is necessary to check whether the diameter, length and shape of the rod blank meet the design tolerance. The surface inspection includes using ultrasonic flaw detection to check surface defects, and repairing or reprocessing the defects found to ensure the integrity of the final product. The hardness test includes using a Brinell hardness tester to perform a hardness test, and selecting multiple points for testing to ensure that the hardness of the material is uniform, and the hardness range is controlled to be HB 200-220. The microstructure inspection includes using a metallographic microscope to observe the microstructure of the material, and check the grain structure, phase distribution and possible inclusions to ensure that the material standards are met and the grain size is controlled to be ≤10μm.

[0057] Through strict dimensional measurement, surface inspection, hardness test and microstructure inspection, the high precision and high quality of high temperature alloy forgings are ensured. Accurate dimensional measurement and surface flaw detection ensure the geometric accuracy and integrity of the product; multi-point hardness test and microstructure analysis verify the uniformity and microstructure of the material, ensuring that the performance of the forgings meets the standards. This series of inspection and quality control measures not only improves the product qualification rate, but also enhances customers' trust in the products, and wins a good reputation for the company in the high-end manufacturing industry.
