Description

Technical Field

[0001] This invention relates to a nickel-based alloy welding material for waste incinerators and its production process, belonging to the field of welding material technology. Background Technology

[0002] Waste incinerators are common waste treatment facilities. The incineration process generates high temperatures and corrosive environments, making material selection crucial. Nickel-based alloys, as high-performance materials, are frequently used in the welding and component manufacturing of incinerators.

[0003] Chinese invention patent CN117415503A discloses a corrosion-resistant nickel-based alloy welding electrode and its manufacturing process. The electrode includes a central stranded welding wire, a fastening mesh surrounding the central stranded welding wire, a polyethylene film surrounding the fastening mesh, an outer layer of stranded welding wire on the outside of the polyethylene film, a combustion accelerant placed in the pores formed between the polyethylene film and the central stranded welding wire, and a protective layer surrounding the outer layer of stranded welding wire. Anti-slip strips are spaced around the protective layer. When the outer welding wire is stranded on the central welding wire body, its staggered arrangement with the central welding wire guide strips guides the stranded wire, preventing changes in the twist pitch, improving the uniformity of the distribution between the central and outer welding wires, enhancing stability, and improving product quality. Furthermore, the positioning strips prevent the outer welding wire from moving away from the central welding wire guide direction and becoming loose, further improving product quality. However, in the existing technology, a central welding wire guide strip is set on the central welding wire body to guide the outer welding wires during stranding, which increases the processing difficulty of the central welding wire and increases the production cost.

[0004] Therefore, there is a need for a nickel-based alloy welding material for waste incinerators and its production process to reduce production difficulty and cost. Summary of the Invention

[0005] The technical problem to be solved by this invention is to overcome the shortcomings of the prior art and provide a nickel-based alloy welding material for waste incinerators and its production process to reduce production difficulty and cost.

[0006] The technical solution adopted by the present invention to solve the above problems is as follows: a nickel-based alloy welding material for waste incinerators, comprising a central stranded welding wire, a fastening mesh surrounding the central stranded welding wire, a polyethylene film surrounding the fastening mesh, an outer layer of stranded welding wire surrounding the polyethylene film, a combustion aid disposed in the pores formed between the polyethylene film and the central stranded welding wire, and a protective layer surrounding the outer layer of stranded welding wire; the central stranded welding wire comprises a central welding wire, and outer welding wires are stranded around the periphery of the central welding wire. The peripheral welding wire includes multiple first peripheral wires and multiple second peripheral wires. The multiple first peripheral wires and multiple second peripheral wires correspond one-to-one and interlock. The diameter of the first peripheral wire is larger than the diameter of the second peripheral wire. The point where the second peripheral wire abuts the first peripheral wire is located on the side of the first peripheral wire axis closer to the central welding wire. The central welding wire is a hollow structure, and multiple grooves are provided on the outer peripheral wall of the central welding wire. Each of the multiple grooves corresponds to a multiple of the first peripheral wires, and the first peripheral wires are inserted into the grooves. The central stranded welding wire also includes multiple clamps, which are spaced apart along the length of the central welding wire and are clamped on the outer periphery of the outer welding wire.

[0007] Preferably, the fastening mesh includes multiple first reinforcing wires and multiple second reinforcing wires, the multiple first reinforcing wires and multiple second reinforcing wires intersecting and winding around a central stranded welding wire.

[0008] Preferably, the protective layer is provided with anti-slip strips at intervals around its perimeter.

[0009] Preferably, both the central stranded welding wire and the outer stranded welding wire are made of nickel-based alloy.

[0010] A manufacturing process for nickel-based alloy welding materials for waste incinerators includes the following steps: Step S1: Preparation of the center stranded welding wire; Step S1.1: Twist multiple first outer perimeter wires and multiple second outer perimeter wires onto the central welding wire, with the multiple first outer perimeter wires and multiple second outer perimeter wires arranged alternately. Step S1.2: Press multiple first peripheral wires toward the direction of the center welding wire, and make multiple first peripheral wires correspond and abut with multiple second peripheral wires one by one. At the same time, the pressing of the first peripheral wires causes the outer peripheral wall of the center welding wire to be concave, which is the groove. Step S1.3: Place multiple clamps at intervals along the length of the central welding wire on the outer periphery of the outer welding wire; Step S2: Installing the fastening net; The prepared central stranded welding wire is passed through a forming machine, which intersects and winds multiple first reinforcing wires and multiple second reinforcing wires onto the central stranded welding wire. Step S3: Applying the combustion accelerant; After the fastening mesh is wrapped around the center stranded welding wire, it passes through a mold containing a combustion accelerator, and the combustion accelerator in the mold is evenly applied to the outer surface of the center stranded welding wire. Step S4: Wrapping with polyethylene film; After the combustion enhancer is evenly applied to the center stranded welding wire, the whole thing passes through the coating machine. As the center stranded welding wire moves, the coating machine tightly wraps the polyethylene film around its outside. Step S5: Twisting of the outer layer welding wire; A central stranded welding wire processed in step S4 is twisted together with multiple outer stranded welding wires to obtain the stranded welding wire body. Step S6: Covering with the protective layer; A protective layer is applied to the outer periphery of the stranded welding wire body obtained in S5; Step S7: Preparation of anti-slip strips; The stranded welding wire covered with the protective layer in step S6 is passed through a trimming machine. The trimming machine cuts off the excess scrap material of the protective layer, and then a ring of anti-slip strips is set at intervals on the protective layer around the stranded welding wire body to finally obtain the required stranded welding wire.

[0011] Preferably, step S1.2 is performed using an extrusion device; The extrusion equipment includes a base, an extrusion seat is provided on the base, a rotating tube is horizontally inserted through the extrusion seat, the rotating tube is rotatably connected to the extrusion seat, a drive system is connected to the rotating tube, the rotation of the rotating tube is realized by the drive system, and an extrusion mechanism is connected to the rotating tube.

[0012] Preferably, multiple adjusting plates are provided between the fixed plate and the mounting base, and the position of the pressure roller is adjusted by changing the number of adjusting plates.

[0013] Preferably, there are two extrusion mechanisms, which are symmetrically arranged on both sides of the extrusion seat along the axis of the rotating tube.

Compared with the prior art, the advantages of the present invention are as follows: This invention discloses a nickel-based alloy welding material for waste incinerators and its manufacturing process. After the first outer wire is stranded with the central welding wire, the first outer wire is pressed, causing it to create a groove on the outer wall of the central welding wire. Thus, the positioning between the first outer wire and the central welding wire is achieved through the cooperation between the first outer wire and the groove.

Detailed Implementation

[0018] like Figures 1 to 4As shown, a nickel-based alloy welding material for a waste incinerator in this embodiment includes a central stranded welding wire 1, a fastening mesh 2 surrounding the central stranded welding wire 1, a polyethylene film 3 surrounding the fastening mesh 2, an outer stranded welding wire 4 surrounding the polyethylene film 3, a combustion aid 5 disposed in the pores formed between the polyethylene film 3 and the central stranded welding wire 1, a protective layer 6 surrounding the outer stranded welding wire 4, and anti-slip strips 7 spaced apart around the protective layer 6. The central stranded welding wire 1 includes a central welding wire 11, and a peripheral welding wire 12 is stranded around the outer periphery of the central welding wire 11. The peripheral welding wire 12 includes multiple first peripheral wires 121 and multiple second peripheral wires 122. The multiple first peripheral wires 121 and multiple second peripheral wires 122 correspond one-to-one and interlock. The specific number of first peripheral wires 121 is six. The diameter of the first peripheral wires 121 is larger than the diameter of the second peripheral wires 122. The point where the second peripheral wires 122 and the first peripheral wires 121 interlock is located on the side of the axis of the first peripheral wires 121 closer to the central welding wire 11. The central welding wire 11 is a hollow structure, and multiple grooves 13 are provided on the outer peripheral wall of the central welding wire 11. The multiple grooves 13 correspond one-to-one with multiple first peripheral wires 121, and the first peripheral wires 121 are inserted into the grooves 13. The central stranded welding wire 1 also includes a plurality of clamps 14, which are spaced apart along the length of the central welding wire 11, and the clamps 14 are clamped on the outer periphery of the outer welding wire 12. Both the central stranded welding wire 1 and the outer stranded welding wire 4 are made of nickel-based alloy. Nickel-based alloy refers to a class of alloys that have high strength and certain resistance to oxidation and corrosion at high temperatures of 650℃ to 1000℃. The fastening mesh 2 includes multiple first reinforcing wires 21 and multiple second reinforcing wires 22. The multiple first reinforcing wires 21 and multiple second reinforcing wires 22 intersect and are wound around the central stranded welding wire 1. The fastening mesh 2 is made of stainless steel. A manufacturing process for nickel-based alloy welding materials for waste incinerators includes the following steps: Step S1: Preparation of the center stranded welding wire 1; Step S1.1: Twist multiple first peripheral wires 121 and multiple second peripheral wires 122 onto the center welding wire 11, and arrange the multiple first peripheral wires 121 and multiple second peripheral wires 122 alternately. Step S1.2: Press multiple first peripheral wires 121 toward the center welding wire 11, and make multiple first peripheral wires 121 correspond to and abut with multiple second peripheral wires 122 one by one. At the same time, the pressing of the first peripheral wires 121 causes the outer peripheral wall of the center welding wire 11 to be recessed, which is the groove 13. Step S1.3: Place multiple clamps 14 at intervals along the length of the central welding wire 11 on the outer periphery of the outer welding wire 12; Step S2, fastening net 2; The prepared central stranded welding wire 1 is passed through a forming machine, which intersects and winds multiple first reinforcing wires 21 and multiple second reinforcing wires 22 onto the central stranded welding wire 1. Step S3, application of combustion accelerator 5; After the fastening mesh 2 is wrapped around the center stranded welding wire 1, it passes through a mold containing a combustion accelerator 5, and the combustion accelerator 5 in the mold is evenly applied to the outer surface of the center stranded welding wire 1. Step S4: Wrapping with polyethylene film 3; After the combustion enhancer 5 is evenly applied to the center stranded welding wire 1, the whole thing passes through the plastic coating machine. As the center stranded welding wire 1 moves, the plastic coating machine tightly wraps the polyethylene film 3 around its outside. Step S5: Twisting of the outer layer welding wire; A central stranded welding wire 1, which has been processed in step S4, is twisted together with multiple outer stranded welding wires 4 to obtain the stranded welding wire body. Step S6, covering with protective layer 6; A protective layer 6 is applied around the stranded welding wire body obtained in S5. Step S7, preparation of anti-slip strip 7; The stranded welding wire covered with protective layer 6 in step S6 is passed through a trimming machine. The trimming machine cuts off the excess scrap material of protective layer 6. Then, a ring of anti-slip strips 7 is set at intervals on the protective layer 6 around the body of the stranded welding wire to finally obtain the required stranded welding wire. When twisting in steps S1 and S5, the tension must be adjusted properly. If the tension is too low, the outer wires will be uneven in tightness and the structure will be loose, which will have adverse effects on the welding arc. If the tension is too high, the tensile strength of the multi-stranded welding wire will decrease significantly and it will be easy to break. The stranded welding wire obtained in step S7 should have good directionality, good rigidity, good wire feeding stability and high yield strength to ensure that the welding wire can be stably melted and enter the molten pool during the welding process. Step S1.2 is performed using extrusion equipment 8; like Figures 5 to 9 As shown, the extrusion device 8 includes a base 81, an extrusion seat 82 is provided on the base 81, a rotating tube 83 is horizontally passed through the extrusion seat 82, the rotating tube 83 is rotatably connected to the extrusion seat 82, a drive system is connected to the rotating tube 83, the rotation of the rotating tube 83 is realized by the drive system, and an extrusion mechanism 84 is connected to the rotating tube 83. The extrusion mechanism 84 includes a plurality of extrusion components 841, which are evenly distributed circumferentially around the axis of the rotating tube 83, and the specific number of the extrusion components 841 is six. The extrusion assembly 841 includes a pressure roller 8411. The outer peripheral wall of the pressure roller 8411 is provided with an arc-shaped annular groove 8412. The annular groove 8412 matches the first peripheral wire 121. A fixing bracket 8413 is provided on the side of the pressure roller 8411 away from the axis of the rotating tube 83. The fixing bracket 8413 is fixedly mounted on the rotating tube 83 by screws 8414. The fixing bracket 8413 is connected to the mounting base 8416 of the pressure roller 8411 by bolts 8415. Multiple adjusting plates 8417 are provided between the fixed non-removable plate 8413 and the mounting base 8416. The multiple adjusting plates 8417 are stacked and arranged. The position of the pressure roller 8411 is adjusted by changing the number of adjusting plates 8417. Two extrusion mechanisms 84 are provided, and the two extrusion mechanisms 84 are symmetrically arranged on both sides of the extrusion seat 82 along the axis of the rotating tube 83. In the two extrusion mechanisms 84, the distance between the pressure roller 8411 in one extrusion mechanism 84 and the axis of the rotating tube 83 is greater than the distance between the pressure roller 8411 in the other extrusion mechanism 84 and the axis of the rotating tube 83. When the extrusion mechanism 84 is in operation, the central stranded welding wire 1, after being processed in step S1.1, passes through the rotating tube 83, and the annular groove 8412 on the pressure roller 8411 abuts against the first peripheral wire 121. The pressure roller 8411 extrudes the first peripheral wire 121, causing the first peripheral wire 121 to be pressed into the direction closer to the central welding wire 11. During operation, the rotating tube 83 is rotated by the drive system, and the rotation of the rotating tube 83 drives the pressure roller 8411 to rotate synchronously, so that the pressure roller 8411 is always in contact with the spiral first outer wire 121. When the central stranded welding wire 1 passes through the rotating tube 83, it first performs the extrusion action through the extrusion mechanism 84, which has a large distance between the pressure roller 8411 and the axis of the rotating tube 83. The drive system includes a drive wheel 85 and a driven wheel 86. The driven wheel 86 is mounted on the outer peripheral wall of the rotating tube 83. The drive wheel 85 is driven by a motor 87. The drive wheel 85 and the driven wheel 86 are connected by a transmission belt 88. When the motor 87 starts, it causes the drive wheel 85 to rotate. The rotation of the drive wheel 85 drives the rotating tube 83 to rotate through the transmission belt 88. It should be noted that, since the center welding wire 11 is a hollow structure, protective gas can be filled inside the hollow structure, thereby improving the protection of the welding area and reducing the contamination of oxidation and molten metal. In summary, after the first peripheral wire 121 is twisted around the central welding wire 11, pressing the first peripheral wire 121 causes it to create a groove 13 on the outer periphery of the central welding wire 11. Thus, the positioning between the first peripheral wire 121 and the central welding wire 11 is achieved through the cooperation between the first peripheral wire 121 and the groove 13. Furthermore, the positioning of the second peripheral wire 122 is achieved by the first peripheral wire 121 abutting against the second peripheral wire 122. Finally, the radial positioning of the peripheral welding wire 12 is achieved through the clamp 14. This avoids the need for a guide strip for the central welding wire 11, reducing production difficulty and costs.
