Description

Technical Field

[0001] The invention relates to the field of homogenization forging methods and radial forging machinery, and in particular to intelligent forging equipment and method for processing seamless steel pipes. Background Art

[0002] Seamless steel pipes made of titanium alloys have excellent mechanical properties, such as high strength, low density, and good corrosion resistance. Titanium alloys are often used to make seamless steel pipes in some specific application fields. For example, in the fields of aerospace, chemical equipment, marine engineering, and high-end sports equipment, titanium alloy seamless steel pipes are favored due to their excellent performance.

[0003] For example, the publication number is CN114178452B, and the name is a seamless steel pipe radial forging equipment and forging method thereof, which includes a vertically arranged frame, with axial feed components and lubrication systems respectively arranged on both sides of the frame; a hammer forging component is arranged on the frame; the hammer forging component includes two symmetrically arranged steering wheels in a circular ring structure, each steering wheel rotates around its own axis, and a group of hammer head assemblies are arranged in each steering wheel, each group of hammer head assemblies includes a plurality of hammer heads movably arranged in the steering wheel, and the plurality of hammer heads are evenly arranged in a ring with the center of the steering wheel as the center; each hammer head is matched with a hydraulic cylinder, and the hydraulic cylinder drives the hammer head to reciprocate along the radial direction of the steering wheel; the two turntables rotate around their own axes, so as to realize the hammer forging of different circumferential parts of the hollow steel ingot by the hammer head, and the hollow steel ingot does not need to perform rotational motion during the entire forging process, thereby improving the positioning accuracy, and further improving the radial forging efficiency and dimensional accuracy of the seamless steel pipe.

[0004] However, the above-mentioned is an all-round hammering treatment of the hollow steel ingot after production, and is not a hammering treatment of the solid titanium alloy cylindrical blank roll. Since the hollow steel ingot is not compacted inside the solid titanium alloy cylindrical blank roll, the overall density of the material cannot be adjusted by hammering to reduce potential stress concentration points. Moreover, the hollow steel ingot after the above-mentioned hammering has not undergone surface treatment, so that the internal stress of the titanium alloy cylindrical blank roll during the plastic deformation process of the forging process cannot be completely released, thereby increasing the possibility of crack initiation, and the surface of the produced seamless steel pipe has not been treated and has poor wear resistance and corrosion resistance. Therefore, the present application provides an intelligent forging equipment and method based on seamless steel pipe processing to meet the needs. Summary of the invention

[0005] The purpose of this application is to provide an intelligent forging device and method for seamless steel pipe processing, which can effectively solve the problems raised in the above background technology.

The inner wall of the inner supporting tube is provided with three groups of stabilizing frames distributed in a circular array, and pressure rollers are rotatably installed inside the stabilizing frames.

[0009] Among them, the coating processing mechanism also includes an outer cylinder, which is installed on one side of the insulation layer, and the inner ring shell is installed on the inner wall of the outer cylinder to form a sealed space. The outer surface of the outer cylinder is provided with a plurality of double-way tubes connected to the interior of the cone spray piece, and a plurality of powder spraying ring tubes are commonly connected to the interior of the double-way tubes. The outer surface of the outer cylinder is provided with a plurality of connecting tubes distributed in a circular array, and the outer surfaces of the plurality of connecting tubes are commonly provided with ventilation ring tubes.

[0010] Among them, the forging hammer mechanism includes a supporting cylinder frame, which is installed inside the supporting frame and on one side of the outer cylinder.

[0012] Wherein, the hammer pressing mechanism includes an arc-shaped pushing assembly, and the arc-shaped pushing assembly includes a mounting ring, the mounting ring is mounted on one end of the push rod, and one end of the mounting ring is connected to an arc top plate.

[0013] Wherein, the hammer pressing mechanism includes a wave pushing assembly, and the wave pushing assembly includes a sleeve, and the sleeve is installed at one end of the top rod, and one end of the sleeve is connected to the ridge top plate.

[0014] Wherein, the surface of the ridge top plate is in a wave shape.

[0015] The present invention also provides a method for using the intelligent forging equipment for processing seamless steel pipes, and the specific method of use is as follows: Step 1: The titanium alloy cylindrical blank roller is fed into the forging hammer mechanism through the conveying roller, and the forging hammer mechanism is used to hammer the titanium alloy cylindrical blank roller through the hammer pressing mechanism. The titanium alloy cylindrical blank roller closes the small internal gaps and holes by hammering, thereby reducing the pores and shrinkage inside the material; Step 2: After being hammered by the forging hammer mechanism, the titanium alloy cylindrical blank roller is sent to the coating treatment mechanism for surface treatment, and the coating treatment mechanism simultaneously sprays a surface modifier and an oxidizing protective gas onto the surface of the titanium alloy cylindrical blank roller, thereby performing a coating treatment on the surface of the titanium alloy cylindrical blank roller; Step three, after the surface of the titanium alloy cylindrical blank roller is sprayed with a modifier and an oxidizing protective gas through a coating treatment mechanism, the titanium alloy cylindrical blank roller will be sent into the interior of the temperature control mechanism for heating treatment, so that the titanium alloy cylindrical blank roller is shaped through the supporting and correcting mechanism when it is in a high temperature state, thereby refining the grain structure and enhancing the mechanical properties of the material. Moreover, the surface modifier and the oxidizing protective gas adsorbed on the surface of the titanium alloy cylindrical blank roller can obtain a more uniform and fine grain structure after hot forging, thereby improving the overall strength and toughness of the material, and forming a strengthening layer on its surface to increase wear resistance and corrosion resistance.

[0016] In summary, the technical effects and advantages of the present invention are as follows: 1. The present invention can force metal to flow and fill small gaps and holes inside the material through the hammering force of the forging hammer mechanism, reduce the pores and shrinkage inside the material, not only improve the overall density of the material, but also reduce potential stress concentration points, thereby enhancing the reliability of the material. In addition, during the forging process, the titanium alloy is subjected to repeated plastic deformation, resulting in the original coarse grains being broken into finer grains. Grain refinement helps to improve the strength and toughness of the material. For the titanium alloy cylindrical blank roller, its performance depends to a large extent on the ratio and distribution of the α phase and the β phase. Appropriate forging technology can optimize the distribution of these phases to make it more uniform, thereby improving the overall performance of the material. Due to grain refinement and the reduction of internal defects, the titanium alloy cylindrical blank roller after the all-round hammering treatment of the forging hammer mechanism has higher tensile strength, yield strength and hardness. The plastic deformation during the forging process helps to release internal stress and reduce the possibility of crack initiation, thereby improving the fracture toughness and fatigue life of the material.

[0017] 2. The present invention can form a coating that is uniform and closely fits the substrate by simultaneously spraying a surface modifier and an oxidizing protective gas onto the surface of the titanium alloy cylindrical blank roller. The coating can not only provide additional wear resistance and corrosion resistance, but also react with the substrate material during the subsequent heating process to form a more solid bonding interface. Under high temperature conditions, the oxidizing protective gas (such as argon or nitrogen) can effectively prevent the titanium alloy surface from contacting oxygen in the air, avoid unnecessary oxide scale formation, and maintain surface quality. When the titanium alloy cylindrical blank roller is heated in the temperature control mechanism, it is in a high temperature state, which helps to activate the atomic diffusion mechanism, so that the grains can be rearranged and refined. The refinement not only enhances the strength and toughness of the material, but also improves its mechanical properties. The surface adsorbed modifier may react metallurgically with the titanium alloy substrate at high temperature to form a strengthening layer with excellent wear resistance and corrosion resistance.

DETAILED DESCRIPTION

[0021] 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.

[0022] Example 1, Reference Figures 1 to 15 An intelligent forging device for seamless steel pipe processing is shown, comprising a titanium alloy cylindrical blank roller 2 and a temperature control mechanism 1 for heating and raising the temperature of the titanium alloy cylindrical blank roller 2, a supporting and correcting mechanism 6 for shaping and straightening the titanium alloy cylindrical blank roller 2 is arranged on one side of the temperature control mechanism 1, a supporting frame 3 is arranged on one side of the temperature control mechanism 1, a forging hammer mechanism 4 for simultaneously hammering the titanium alloy cylindrical blank roller 2 in multiple directions is arranged inside the supporting frame 3, a hammer pressing mechanism 7 for controlling the hammering shape of the surface of the titanium alloy cylindrical blank roller 2 is arranged inside the forging hammer mechanism 4, and a coating treatment mechanism 5 for changing the surface performance of the titanium alloy cylindrical blank roller 2 is arranged between the hammer pressing mechanism 7 and the temperature control mechanism 1; It is worth noting that the titanium alloy cylindrical blank roller 2 is fed into the forging hammer mechanism 4 through the conveying roller, and the forging hammer mechanism 4 hammers the titanium alloy cylindrical blank roller 2 through the hammer pressing mechanism 7, and the titanium alloy cylindrical blank roller 2 closes the small internal gaps and holes by hammering, thereby reducing the pores and shrinkage inside the material; Among them, the hammering force can force the metal to flow, fill the small gaps and holes inside, reduce the porosity and shrinkage inside the material, which not only improves the overall density of the material, but also reduces potential stress concentration points, thereby enhancing the reliability of the material. In addition, during the forging process, the titanium alloy is subjected to repeated plastic deformation, causing the original coarse grains to be broken into finer grains. Grain refinement helps to improve the strength and toughness of the material.

[0023] For the titanium alloy cylindrical blank roller 2, its performance depends to a large extent on the proportion and distribution of α phase and β phase. Appropriate forging process can optimize the distribution of these phases and make them more uniform, thereby improving the overall performance of the material. Due to grain refinement and reduction of internal defects, the titanium alloy cylindrical blank roller 2 after all-round hammering treatment by the forging hammer mechanism 4 has higher tensile strength, yield strength and hardness. The plastic deformation during the forging process helps to release internal stress and reduce the possibility of crack initiation, thereby improving the fracture toughness and fatigue life of the material.

[0024] After being hammered by the forging hammer mechanism 4, the titanium alloy cylindrical blank roller 2 is sent to the coating treatment mechanism 5 for surface treatment, and the coating treatment mechanism 5 simultaneously sprays the surface modifier and the oxidizing protective gas to the surface of the titanium alloy cylindrical blank roller 2, thereby performing coating treatment on the surface of the titanium alloy cylindrical blank roller 2; After the surface of the titanium alloy cylindrical blank roller 2 is sprayed with a modifier and an oxidizing protective gas through the coating treatment mechanism 5, the titanium alloy cylindrical blank roller 2 will be sent to the interior of the temperature control mechanism 1 for heating treatment, so that the titanium alloy cylindrical blank roller 2 is shaped through the supporting and correcting mechanism 6 when it is in a high temperature state, thereby refining the grain structure and enhancing the mechanical properties of the material. Moreover, the surface modifier and the oxidizing protective gas adsorbed on the surface of the titanium alloy cylindrical blank roller 2 can obtain a more uniform and fine grain structure after hot forging, thereby improving the overall strength and toughness of the material, and forming a strengthening layer on its surface to increase wear resistance and corrosion resistance. Finally, the titanium alloy cylindrical blank roller 2 is sent to the pipe rolling machine to be made into a seamless steel pipe.

[0025] Among them, by simultaneously spraying a surface modifier and an oxidizing protective gas onto the surface of the titanium alloy cylindrical blank roller 2, a coating that is uniform and tightly fits the substrate can be formed. The coating not only provides additional wear resistance and corrosion resistance, but also reacts with the substrate material during the subsequent heating process to form a more solid bonding interface. Under high temperature conditions, oxidizing protective gases such as argon or nitrogen can effectively prevent the titanium alloy surface from contacting oxygen in the air, avoid unnecessary oxide scale formation, and maintain surface quality.

[0026] When the heating treatment is carried out in the temperature control mechanism 1, the titanium alloy cylindrical blank roller 2 is in a high temperature state, which helps to activate the atomic diffusion mechanism so that the grains can be rearranged and refined. The refinement not only enhances the strength and toughness of the material, but also improves its mechanical properties. The modifier adsorbed on the surface may undergo metallurgical reaction with the titanium alloy matrix at high temperature to form a strengthening layer with excellent wear resistance and corrosion resistance.

[0027] When shaping is performed in the support and correction mechanism, the titanium alloy cylindrical blank roller 2 can be more easily adjusted to the desired size and shape at high temperature. By shaping at high temperature, the residual stress after cooling can be reduced, thereby reducing the risk of deformation or cracking due to stress concentration during subsequent use.

[0028] Moreover, the titanium alloy cylindrical blank roll 2 processed through all the above-mentioned processes is finally sent to the pipe-rolling machine to be made into seamless steel pipes. These steel pipes have high strength, good toughness and excellent corrosion resistance, and are very suitable for applications in extreme environments, such as aerospace, marine engineering and chemical industries.

[0029] Embodiment 2: Based on the forging hammer mechanism 4 provided in Embodiment 1, this embodiment provides a further technical solution of the forging hammer mechanism 4.

[0030] The forging hammer mechanism 4 includes a support cylinder frame 41, which is installed inside the support frame 3 and on one side of the outer cylinder 54. A waste opening 45 is provided at the bottom of the outer surface of the outer cylinder 54, and a plurality of mounting grooves 44 distributed in a circular array are provided on the outer surface of the support cylinder frame 41.

[0031] A reciprocating cylinder 42 is disposed inside the mounting groove 44 , an air spraying member 43 is disposed at one end of the reciprocating cylinder 42 , a pressure air pipe 46 is disposed inside the air spraying member 43 , a plug rod 47 is disposed inside the reciprocating cylinder 42 , and a push rod 48 is disposed on one side of the plug rod 47 .

[0032] It is worth mentioning that after the titanium alloy cylindrical blank roller 2 is transported to the interior of the support drum frame 41, the air spray component 43 is controlled by the pressure air pipe 46, and the air spray component 43 is combined with the reciprocating cylinder 42 to belong to the air hammer in the prior art. The plug rod component 47 is controlled by compressed air to reciprocate inside the reciprocating cylinder 42, and the plug rod component 47 will push the push rod 48 to move, and the hammer pressing mechanism 7 is pushed by the push rod 48 to hammer the surface of the titanium alloy cylindrical blank roller 2. The reciprocating cylinders 42 are distributed in a circular array, and can hammer the surface of the titanium alloy cylindrical blank roller 2 at multiple angles and orientations at the same time.

[0033] Among them, since the reciprocating cylinders 42 are distributed in a circular array, it can ensure that the titanium alloy cylindrical blank roller 2 is evenly hammered from multiple angles and directions, thereby achieving uniform deformation of the internal structure of the material and avoiding local stress concentration. Uniform and comprehensive hammering helps to produce consistent plastic deformation throughout the workpiece volume, thereby promoting grain refinement and improving the overall strength and toughness of the material. Multi-directional hammering helps to close small gaps and holes inside the material and reduce pores and shrinkage.

[0034] Embodiment 3: This embodiment provides a technical solution for the arc-shaped pushing component 8 in the hammer pressing mechanism 7.

[0035] The hammer pressing mechanism 7 includes an arc-shaped push assembly 8 , and the arc-shaped push assembly 8 includes a mounting ring 82 . The mounting ring 82 is mounted on one end of the push rod 48 , and one end of the mounting ring 82 is connected to an arc top plate 81 .

[0036] It is worth mentioning that when the push rod 48 moves, it will drive the mounting ring 82 to move, and the movement of the mounting ring 82 will push the arc top plate 81 to move, so that the arc top plate 81 pushes and hammers on the surface of the titanium alloy cylindrical blank roller 2, and the surface of the arc top plate 81 is in an arc shape. Through the cooperation of multiple groups of arc top plates 81, the titanium alloy cylindrical blank roller 2 can be hammered in multiple directions.

[0037] Among them, the curved shape of the arc top plate 81 can better fit the surface contour of the titanium alloy cylindrical blank roller 2, ensuring a more uniform distribution of force during the hammering process, producing consistent plastic deformation on the entire workpiece surface, and avoiding local excessive force or stress concentration. Through the coordinated work of multiple groups of arc top plates 81, a larger surface area can be covered and pressure can be applied from multiple angles, further enhancing the uniformity of deformation. Uniform and comprehensive hammering helps to close small gaps and holes inside the material and reduce pores and shrinkage.

[0038] Embodiment 4: This embodiment provides a technical solution for the wave pushing assembly 9 in the hammer pressing mechanism 7.

[0039] The hammer mechanism 7 includes a wave push assembly 9, which includes a sleeve 92. The sleeve 92 is installed at one end of the push rod 48. One end of the sleeve 92 is connected to a ridge top plate 91, and the surface of the ridge top plate 91 is wavy.

[0040] It is worth mentioning that when the push rod 48 moves, it will drive the sleeve 92 to move, and the sleeve 92 will drive the rib top plate 91 to hammer the surface of the titanium alloy cylindrical blank roller 2. Because the surface of the rib top plate 91 is wavy, when the rib top plate 91 hammers the surface of the titanium alloy cylindrical blank roller 2, the surface of the titanium alloy cylindrical blank roller 2 is distorted, which can increase the coverage area of ​​the coating when the subsequent coating processing mechanism 5 sprays.

[0041] Among them, the wavy shape of the ridge top plate 91 will cause micro-distortion or unevenness on the surface of the titanium alloy cylindrical blank roller 2 during the hammering process. The increase in surface roughness can significantly improve the adhesion and coverage area of ​​the coating material during subsequent coating treatment, because more coating material can be embedded in these tiny bumps and depressions to form a mechanical locking effect.

[0042] By increasing the surface roughness, the physical bond between the coating and the substrate is strengthened, thereby improving the overall bonding strength and durability of the coating. The impact force during the hammering process helps to activate the diffusion mechanism of atoms inside the titanium alloy and promote grain refinement, which not only enhances the hardness and strength of the material, but also improves its toughness.

[0043] Embodiment 5: Based on the coating processing mechanism 5 proposed in Embodiment 1, this embodiment provides a technical solution for the coating processing mechanism 5.

[0044] The coating treatment mechanism 5 comprises an inner ring shell 56 and a plurality of cone spraying parts 55 for spraying the surface modifier. The inner wall of the inner ring shell 56 is provided with a plurality of spray holes 57 for spraying the oxidizing protective gas.

[0045] The coating processing mechanism 5 also includes an outer cylinder 54, which is installed on one side of the insulation layer 12, and an inner ring shell 56 is installed on the inner wall of the outer cylinder 54 to form a sealed space. The outer surface of the outer cylinder 54 is provided with a plurality of double-way tubes 53 connected to the inside of the cone spray piece 55, and a plurality of powder spraying ring tubes 58 are commonly connected to the inside of the double-way tubes 53. The outer surface of the outer cylinder 54 is provided with a plurality of connecting tubes 52 distributed in a ring array, and the outer surfaces of the plurality of connecting tubes 52 are commonly provided with ventilation ring tubes 51.

[0046] It is worth noting that, after the titanium alloy cylindrical blank roller 2 is hammered by the hammer pressing mechanism 7, the titanium alloy cylindrical blank roller 2 will be sent into the interior of the inner ring shell 56, and the powder spraying ring tube 58 will spray the surface modifier to the interior of the cone spraying part 55 through the double-way pipe 53, and the surface modifier will be sprayed on the surface of the titanium alloy cylindrical blank roller 2 through the cone spraying part 55, and the cone spraying part 55 is distributed in a ring array, which can spray the surface of the titanium alloy cylindrical blank roller 2 in all directions, and after the surface modifier is sprayed, it is heated by the temperature control mechanism 1 to ensure the good combination and uniform distribution of the surface modifier and the titanium alloy cylindrical blank roller 2; Moreover, when the conical spray piece 55 is sprayed on the surface of the titanium alloy cylindrical blank roller 2, the ventilation ring tube 51 will fill the oxidizing protective gas into the cavity between the outer tube 54 and the inner ring shell 56 through the connecting tube 52, and the gas will be sprayed on the surface of the titanium alloy cylindrical blank roller 2 through the jet hole 57. The jet hole 57 can spray the oxidizing protective gas on the surface of the titanium alloy cylindrical blank roller 2 in all directions, so that the nitrogen oxide protective gas atoms are diffused into the surface layer of the titanium alloy cylindrical blank roller 2 during the subsequent heating process of the titanium alloy cylindrical blank roller 2 inside the temperature control mechanism 1, forming a layer of anti-oxidation layer with higher hardness, thereby improving wear resistance and corrosion resistance.

[0047] Among them, by spraying the surface modifier and combining it with subsequent heating treatment, the surface modifier can be well combined with the surface of the titanium alloy cylindrical blank roller 2 to form a layer of antioxidant layer with high hardness. The protective layer not only improves the wear resistance of the material, but also effectively resists the erosion of corrosive media. The design of the cone spray parts 55 distributed in a ring array ensures that the surface modifier can be sprayed on the surface of the titanium alloy cylindrical blank roller 2 in an all-round and uniform manner. The ventilation ring tube 51 fills the oxidizing protective gas into the cavity between the outer cylinder 54 and the inner ring shell 56 through the connecting tube 52, and sprays it onto the surface of the titanium alloy cylindrical blank roller 2 through the jet hole 57, which helps to prevent unnecessary oxidation reactions of the titanium alloy during high-temperature heating, thereby maintaining its original characteristics and performance. During the heating process, the atoms in the nitrogen oxide protective gas can diffuse into the surface layer of the titanium alloy cylindrical blank roller 2, forming a surface layer with higher hardness and better oxidation resistance.

[0048] Embodiment 6: Based on the temperature control mechanism 1 proposed in Embodiment 1, this embodiment provides a technical solution for the temperature control mechanism 1.

[0049] The temperature control mechanism 1 comprises a heat-insulating layer 12 , a support frame 11 is arranged on the outer surface of the heat-insulating layer 12 , a support frame 3 is installed on one side of the support frame 11 , and a graphite heating inner tube 13 is arranged on the inner wall of the heat-insulating layer 12 .

[0050] The support and correction mechanism 6 includes an inner support tube 61, which is fixedly installed on one side of the insulation layer 12. The inner wall of the inner support tube 61 is provided with three groups of stabilizing frames 62 distributed in a circular array, and pressure rollers 63 are rotatably installed inside the stabilizing frames 62.

[0051] It is worth noting that after the titanium alloy cylindrical blank roller 2 is transported to the interior of the insulation layer 12, the titanium alloy cylindrical blank roller 2 is heated by the graphite heating inner tube 13, and then the titanium alloy cylindrical blank roller 2 is sent to the position of the pressing roller wheel 63 for straightening treatment; Among them, graphite, as an excellent electric heating material, has good electrical conductivity and high temperature resistance, can provide uniform and efficient heating effect, ensure that the titanium alloy cylindrical blank roller 2 is heated evenly during the entire heating process, and reduce stress concentration or deformation caused by uneven temperature. Appropriate heat treatment can promote grain refinement in the titanium alloy, thereby improving the mechanical properties of the material, such as strength, hardness and toughness. By controlling the heating temperature and time, the internal microstructure of the titanium alloy can be optimized to achieve the optimal state.

[0052] The heated titanium alloy material will shrink to a certain extent when cooling, and the prior straightening treatment can help reduce the rebound effect of the material after cooling. Heat treatment combined with straightening treatment can help release the residual stress inside the material and reduce stress concentration problems caused by work hardening or rapid cooling.

[0053] The present invention also provides a method for using the intelligent forging equipment for processing seamless steel pipes, and the specific method of use is as follows: Step 1: The titanium alloy cylindrical blank roller 2 is fed into the forging hammer mechanism 4 through the conveying roller, and the forging hammer mechanism 4 hammers the titanium alloy cylindrical blank roller 2 through the hammer pressing mechanism 7. The titanium alloy cylindrical blank roller 2 closes the small internal gaps and holes by hammering, thereby reducing the pores and shrinkage inside the material; Step 2: After being hammered by the forging hammer mechanism 4, the titanium alloy cylindrical blank roller 2 is sent to the coating treatment mechanism 5 for surface treatment, and the coating treatment mechanism 5 simultaneously sprays a surface modifier and an oxidizing protective gas onto the surface of the titanium alloy cylindrical blank roller 2, thereby performing a coating treatment on the surface of the titanium alloy cylindrical blank roller 2; Step three, after the surface of the titanium alloy cylindrical blank roller 2 is sprayed with a modifier and an oxidizing protective gas through the coating treatment mechanism 5, the titanium alloy cylindrical blank roller 2 will be sent to the interior of the temperature control mechanism 1 for heating treatment, so that the titanium alloy cylindrical blank roller 2 is shaped by the supporting and correcting mechanism 6 when it is in a high temperature state, thereby refining the grain structure and enhancing the mechanical properties of the material. Moreover, the surface modifier and the oxidizing protective gas adsorbed on the surface of the titanium alloy cylindrical blank roller 2 can obtain a more uniform and fine grain structure after hot forging, thereby improving the overall strength and toughness of the material, and forming a strengthening layer on its surface to increase wear resistance and corrosion resistance. Finally, the titanium alloy cylindrical blank roller 2 is sent to the pipe rolling machine to be made into a seamless steel pipe.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
