Description

Technical Field

[0001] This invention belongs to the field of testing equipment technology, and specifically relates to a surface wear condition detector for slab / rectangular billet crystallizers and its testing method. Background Technology

[0002] During operation, the surface of the crystallizer is in direct contact with high-temperature molten steel, enduring extremely high temperatures, pressures, and the scouring force generated by the flowing molten steel. As the continuous casting process continues, wear inevitably occurs on the crystallizer surface. Uneven wear on the crystallizer surface will lead to inconsistent cooling rates in different parts of the billet during the cooling process, resulting in uneven stress distribution within the billet. This not only affects the surface quality of the billet, causing defects such as cracks and dents, but may also lead to major production accidents such as steel leakage in severe cases, causing huge economic losses to the enterprise. Therefore, accurate detection of the wear condition of the slab / rectangular billet crystallizer surface is a key link in ensuring the smooth operation of continuous casting production and improving billet quality.

[0003] Furthermore, during the inspection of slab / rectangular billet crystallizers, the crystallizers can be collected in one location and inspected sequentially by a single detector. However, it is also possible to collect the crystallizers in one location or, due to limitations, to inspect them all at once. In such cases, the detector needs to be moved to the location of the crystallizers for individual inspection, requiring the detector to be portable. To address these issues, this invention provides a surface wear condition detector for slab / rectangular billet crystallizers. Summary of the Invention

[0004] To address the aforementioned technical problems, the technical solution adopted by this invention is: a surface wear condition detector for slab / rectangular billet crystallizers, comprising:

[0005] The base is composed of two frame one and two frame two connected together. Guide rails are fixedly installed on the two frame twos, and sliders are slidably installed on the guide rails. The sliders are connected to the linear motion component.

[0006] A horizontal adjustment mechanism; the horizontal adjustment mechanism includes a base plate one and a connecting plate two, the base plate one is movably mounted on the frame two, the connecting plate two is located on the base plate one, and the base plate one and the connecting plate two are connected by an adjustment component.

[0007] A lifting mechanism; the lifting mechanism is mounted on the connecting plate 2, and the lifting mechanism includes a base plate 2 and a rack, the base plate 2 and the connecting plate 2 are detachably connected, and the rack is movably mounted on the base plate 2;

[0008] A rotating mechanism; the rotating mechanism is connected to a rack and pinion, and includes a mounting frame on which a detection mechanism is fixedly mounted. The detection mechanism includes a three-dimensional profile detector. When detection is performed, the rack and pinion drive the rotating mechanism and the three-dimensional profile detector to move vertically, adjusting the height of the three-dimensional profile detector relative to the slab / rectangular billet crystallizer, and adjusting the detection angle of the three-dimensional profile detector relative to the slab / rectangular billet crystallizer through the rotating mechanism.

[0009] Furthermore, the linear motion assembly includes two connecting plates, which are respectively fixedly connected to two sliders. The two connecting plates are connected to the base plate by bolts. Each connecting plate is connected to a timing belt. The timing belt is rotatably mounted on the frame, and both timing belts are connected to a rotating shaft. The rotating shaft is connected to the output shaft of the motor through a coupling. The motor is fixedly mounted on the frame.

[0010] Furthermore, the linear motion assembly includes two linear motors, which are respectively fixedly mounted on two frames. The extended ends of the linear motors are connected to the sliders, and the sliders are connected to the base plate.

[0011] Furthermore, the adjustment assembly includes a support rod and two electric cylinders. The two ends of the support rod are respectively hinged to the base plate and the connecting plate. One end of the electric cylinder is hinged to the base plate, and the extended end of the electric cylinder is connected to the connecting plate via a fisheye bearing.

[0012] Furthermore, the horizontal adjustment mechanism also includes a cable carrier mounted on the base plate, which is used to store cables.

[0013] Furthermore, the lifting mechanism also includes a connecting box, which is fixedly connected to the second base plate. A gear is rotatably installed inside the connecting box. The gear meshes with a rack, and the rack passes through the connecting box and slides with it. One end of the rack extends into the lower part of the second base plate and connects to the rotating mechanism. The gear is connected to a joint module, which is mounted on the connecting box.

[0014] Furthermore, the lifting mechanism also includes a second support rod and a protective cover. The second support rod is fixedly connected to the second base plate and slides with the rack. The protective cover is fixedly installed above the second base plate and is U-shaped. The second support rod is fixedly installed inside the protective cover.

[0015] Furthermore, the lifting mechanism also includes a cable carrier 2 mounted on the base plate 2, which is used to store cables.

[0016] Furthermore, the rotating mechanism includes an upper connecting plate, one side of which is fixedly mounted on the end of the rack located below the second base plate, and the other side of which is fixedly connected to a hollow servo motor. The hollow servo motor is fixedly connected to a lower connecting plate, and the output end of the hollow servo motor passes through the lower connecting plate and is connected to a mounting frame. The mounting frame is fixedly connected to a three-dimensional contour detector.

[0017] On the other hand, this invention discloses a detection method for a surface wear condition detector for slab / rectangular billet crystallizers, comprising the following steps:

[0018] S1: Place the base above the slab / rectangular billet crystallizer;

[0019] S2: Start the electric cylinder to make the electric cylinder adjusting connecting plate two reach a horizontal state. At this time, the rotating mechanism, lifting mechanism and three-dimensional contour detector are in the initial position and there is no deflection.

[0020] S3: Start the linear motion component, which drives the three-dimensional contour detector to move along the long side of the slab / rectangular billet crystallizer and detect the slab / rectangular billet crystallizer through the three-dimensional contour detector until it reaches the corner;

[0021] S4: Start the rotating mechanism to rotate the three-dimensional profile detector 90°, and then drive the three-dimensional profile detector to move along the narrow or wide face of the slab / rectangular billet crystallizer through the linear motion component until it reaches the next corner;

[0022] S5: Repeat the movements of S3 and S4 until the three-dimensional profile detector has finished detecting the same horizontal plane of the slab / rectangular billet crystallizer;

[0023] S6: Start the lifting mechanism to move the 3D contour detector to the next detection plane, and repeat S3-S5 until all detections are completed.

[0024] The advantages of this invention compared with the prior art are: (1) This invention drives the three-dimensional contour detector to move through the horizontal adjustment mechanism, the lifting mechanism and the rotating mechanism to complete the detection of the wear state of the surface of the slab / rectangular billet crystallizer. The structure is simple and easy to use; (2) The two linear motion components disclosed in this invention can adapt to a variety of application scenarios and can be flexibly selected according to the actual detection needs, which improves the detection efficiency; (3) The rotating mechanism can drive the three-dimensional contour detector to perform scanning detection angle adjustment, and the height can be adjusted through the lifting mechanism. It can comprehensively obtain all surface conditions of the slab / rectangular billet crystallizer and obtain accurate detection results. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example: Figure 1 — Figure 9 The slab / rectangular billet crystallizer surface wear condition detector shown includes:

[0043] The base consists of two frames 11 and two frames 12 connected together. Guide rails 15 are fixedly installed on the two frames 12, and sliders 14 are slidably installed on the guide rails 15. The sliders 14 are connected to the linear motion component.

[0044] Specifically, the frame serves as the mounting base for the entire testing instrument. When testing the slab / rectangular billet crystallizer 6, the frame is positioned above it. Frame 11 and Frame 2 12 can be connected by bolts or welding. When Frame 11 and Frame 2 12 are made of carbon fiber, welding is not permitted; they should be connected in a way that does not damage them, such as using clips. Of course, this embodiment focuses on the testing of the slab / rectangular billet crystallizer 6; it is understood that this embodiment remains applicable even if the crystallizer is rectangular.

[0045] In addition, a foot is installed under each frame 11, which serves to provide support and shock absorption. A cable chain 3 is installed on frame 2 12, which is used to store the cables of the linear motion components.

[0046] In this embodiment, the dimensions of the base are 955mm*3000mm*302mm.

[0047] A horizontal adjustment mechanism; the horizontal adjustment mechanism includes a base plate 21 and a connecting plate 24. The base plate 21 is movably mounted on the frame 2 12, and the connecting plate 24 is located on the base plate 21. The base plate 21 and the connecting plate 24 are connected by an adjustment component.

[0048] Specifically, a circular hole is provided at the center of the substrate 21 and the connecting plate 24. The diameter of the circular hole is large enough to allow the mounting bracket 44 and the three-dimensional contour detector 51 to pass through smoothly, as well as to allow the rack 34 to pass through smoothly, so as not to interfere with the rack 34 driving the rotation mechanism and the lifting and lowering of the three-dimensional contour detector 51.

[0049] Lifting mechanism; The lifting mechanism is installed on the connecting plate 24. The lifting mechanism includes a base plate 233 and a rack 34. The base plate 233 is detachably connected to the connecting plate 24. The rack 34 is movably installed on the base plate 23.

[0050] Specifically, the connecting plate 24 and the base plate 33 are disassembled or connected by the locking device 35.

[0051] A rotating mechanism is connected to a rack 34. The rotating mechanism includes a mounting frame 44, on which a detection mechanism is fixedly mounted. The detection mechanism is a three-dimensional profile detector 51. When detection is performed, the rack 34 drives the rotating mechanism and the three-dimensional profile detector 51 to move in the vertical direction, adjusting the height of the three-dimensional profile detector 51 relative to the slab / rectangular billet crystallizer 6. The rotating mechanism adjusts the detection angle of the three-dimensional profile detector 51 relative to the slab / rectangular billet crystallizer 6.

[0052] like Figures 1-9 As shown, when inspecting the wear condition of the slab / rectangular billet crystallizer 6, the frame is fixed directly above the slab / rectangular billet crystallizer 6. At the same time, the connecting plate 24 is adjusted by adjusting the component to make the connecting plate 24 horizontal. The lifting mechanism is adjusted to be directly above the slab / rectangular billet crystallizer 6. Then, the height and angle of the three-dimensional contour detector 51 are adjusted by the lifting mechanism and the rotation mechanism respectively to perform all-round inspection of the slab / rectangular billet crystallizer 6.

[0053] In this embodiment, the test length of the slab / rectangular billet crystallizer 6 is in the range of 200mm to 600mm; the depth is in the range of 1000mm to 1200mm; the measurement accuracy of the three-dimensional contour detector 51 is not less than 0.05mm, the measurement resolution is not less than 0.002mm, and the motion accuracy of the three-dimensional contour detector 51 during movement is not less than 0.01mm.

[0054] After the 3D contour detector 51 completes the scanning (for the slab / rectangular billet crystallizer 6), the data is transmitted to the host computer via wireless or wired communication. The host computer software can import the collected data into the model library and perform calculations and analyses to obtain the multi-tapered condition, surface flatness, and surface wear of the crystallizer. The host computer software intuitively presents the taper condition of the multi-tapered surface of the tested crystallizer to the user through data tables, data curves, and 3D model diagrams. The data results can be presented as a 3D contour map, and the 3D test data can be exported for modeling in software such as Ansys. The data results can also be presented as a 2D unfolded diagram of the 3D contour map, which can clearly show the asymmetric wear of the crystallizer. It is known that the same crystallizer can be measured multiple times at different usage cycles, and a graph showing the relationship between crystallizer wear and time and usage cycles can be generated and compared with the acceptable limit value of crystallizer surface wear. It should be noted that the data obtained through computer software analysis is prior art, which can be known and used by those skilled in the art. How to use software for data analysis is not the focus of this invention and will not be elaborated here.

[0055] The linear motion assembly includes two connecting plates 16, which are fixedly connected to two sliders 14 respectively. The two connecting plates 16 are bolted to the base plate 21. Each connecting plate 16 is connected to a timing belt 17, which is rotatably mounted on the frame 12. Both timing belts 17 are connected to a rotating shaft 18, which is connected to the output shaft of a motor 19 via a coupling. The motor 19 is fixedly mounted on the frame 11.

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, when inspecting the slab / rectangular billet crystallizer 6, the three-dimensional contour detector 51 needs to move along the long side of the slab / rectangular billet crystallizer 6. Specifically, the motor 19, fixedly mounted on a frame 11, is started, causing the output shaft of the motor 19 to drive the rotating shaft 18 to rotate via a coupling. A synchronous pulley that cooperates with the synchronous belt 17 is fixedly mounted on the rotating shaft 18, causing the synchronous pulley on the rotating shaft 18 to drive the synchronous belt 17 to rotate, thereby causing the synchronous belt 17 to drive the connecting plate 16 to move horizontally. The connecting plate 16 is connected to the slider 14, and the slider 14 slides along the horizontal direction of the guide rail 15, which serves as a guide. It can be seen that in this embodiment, the motor 19 is a dual-axis motor, that is, two output shafts. In use, the two output shafts are connected to the two rotating shafts 18 via couplings respectively. In this embodiment, the total weight of the linear motion component and the base is 210kg, which is relatively heavy and not conducive to transportation, but the translational accuracy is stable, making it suitable for long-term use in a fixed position. During testing, simply move the slab / rectangular billet crystallizer 6 under the base.

[0057] During the horizontal movement of the connecting plate 16, the base plate 21, which is bolted to the connecting plate 16, will move, thereby realizing the horizontal movement of the three-dimensional contour detector 51.

[0058] The linear motion assembly includes two linear motors 13, which are fixedly mounted on two frames 12 respectively. The extended ends of the linear motors 13 are connected to sliders 14, and sliders 14 are connected to base plate 21.

[0059] In another embodiment, such as Figure 1 , Figure 5 As shown, the linear motion assembly includes two linear motors 13. When inspecting the slab / rectangular billet crystallizer 6, the three-dimensional contour detector 51 needs to move along the long side of the slab / rectangular billet crystallizer 6. Specifically, the linear motors 13 are activated, causing the extended ends of the linear motors 13 to drive the slider 14 to slide horizontally on the guide rail 15. The slider 14 is connected to the base plate 21, so the base plate 21 also moves horizontally, thereby changing the horizontal detection position of the three-dimensional contour detector 51. In this embodiment, the slider 14 and the base plate 21 can be connected by bolts. In this embodiment, the total weight of the linear motor and base is 40kg, which is lightweight and easy to transport, allowing for inspection in different locations. The detection range is small, but the detection accuracy is still guaranteed.

[0060] The adjustment assembly includes a support rod 22 and two electric cylinders 23. The two ends of the support rod 22 are hinged to the base plate 21 and the connecting plate 24, respectively. One end of the electric cylinder 23 is hinged to the base plate 21, and the extended end of the electric cylinder 23 is connected to the connecting plate 24 through a fisheye bearing.

[0061] like Figure 1 , Figure 6 As shown, when adjusting the level of the connecting plate 24, one or two electric cylinders 23 can be selectively activated to extend or retract the extension end of the electric cylinder 23, thereby adjusting the angle of the connecting plate 24 to be horizontal, ensuring that 3 and 4 are in the initial position, which can improve the detection accuracy of 5. During the adjustment process, the support rod 22 will move accordingly. The function of the support rod 22 is to support the connecting plate 24 and assist in the angle change of the connecting plate 24.

[0062] The horizontal adjustment mechanism also includes a cable carrier 25 disposed on the base plate 21, which is used to store cables.

[0063] like Figure 6 As shown, a cable carrier 25 is mounted on a substrate 21. The cable carrier 25 can accommodate the cable connected to the electric cylinder 23, thus ensuring that the detection effect is not affected by the cable scattering. In this embodiment, the substrate 21 is made of carbon fiber material, and the cable carrier 25 is made of nylon material.

[0064] The lifting mechanism also includes a connecting box 32, which is fixedly connected to the second substrate 33. A gear is rotatably installed inside the connecting box 32. The gear meshes with a rack 34, and the rack 34 passes through the connecting box 32 and slides with the connecting box 32. One end of the rack 34 extends into the lower part of the second substrate 33 and is connected to the rotating mechanism. The gear is connected to the joint module 37, which is mounted on the connecting box 32.

[0065] like Figure 1 , Figure 7 As shown, during the inspection of the slab / rectangular billet crystallizer 6, it is necessary to inspect the slab / rectangular billet crystallizer 6 at different depths, so it is necessary to adjust the height of the three-dimensional contour detector 51.

[0066] During the process of adjusting the height of the three-dimensional contour detector 51, the rack 34 needs to drive the three-dimensional contour detector 51 to rise and fall. Specifically, the joint module 37 installed on the connecting box 32 is activated, so that the extended end of the joint module 37 drives the gear to rotate in the connecting box 32. At this time, the rack 34, which meshes with the gear, moves up or down along the support rod 36. During the process of the rack 34 moving up or down, the rotating mechanism installed below the rack 34 will drive the three-dimensional contour detector 51 to move up or down together, thereby detecting the different heights of the slab / rectangular billet crystallizer 6.

[0067] In this embodiment, the specific information of the joint module 37 is shown in Table 1:

[0068] Table 1: Parameters of Joint Module 37

[0069]

[0070] The lifting mechanism also includes a second support rod 36, which is fixedly connected to the second base plate 33, and the second support rod 36 is slidably engaged with the rack 34.

[0071] like Figure 1 , Figure 8 As shown, support rod 36 guides the sliding of rack 34. In this embodiment, support rod 36 is made of carbon fiber material, model T300, with a diameter of 40mm and a length of 2200mm.

[0072] In another embodiment, as those skilled in the art will know, the second support rod 36 can be replaced with a guide rail (which has the same function and material as the guide rail 15), and a slider (which has the same function and material as the slider 14) can be added to the guide rail, so that the rack 36 is fixedly connected to the slider, which can also achieve smooth sliding of the rack 34.

[0073] The lifting mechanism also includes a protective cover 31, which is fixedly installed above the second base plate 33. The protective cover 31 is U-shaped, and the second support rod 36 is fixedly installed inside the protective cover 31.

[0074] In this embodiment, the protective cover 31 covers the outside of the second support rod 36, serving a protective function, while the second support rod 36 serves as a guide for the rack 34.

[0075] The lifting mechanism also includes a cable carrier 38 mounted on the base plate 33, which is used to store cables.

[0076] like Figure 1 As shown, the cable carrier 2 38 houses the cables used to control the joint module 37. The cable carrier 2 38 can make the wiring neater, keep the work site clean, and prevent the cables from scattering or breaking.

[0077] The rotating mechanism includes an upper connecting plate 41. One side of the upper connecting plate 41 is fixedly installed at one end of the rack 34 located below the base plate 33. The other side of the upper connecting plate 41 is fixedly connected to a hollow servo motor 42. The hollow servo motor 42 is fixedly connected to a lower connecting plate 43, and the output end of the hollow servo motor 42 passes through the lower connecting plate 43 and is connected to a mounting frame 44. The mounting frame 44 is fixedly connected to a three-dimensional contour detector 51.

[0078] like Figure 1 , Figure 9As shown, during the process of adjusting the height of the three-dimensional contour detector 51 by raising and lowering the rack 34, there is a need to adjust the detection angle of the three-dimensional contour detector 51. At this time, it is necessary to adjust the shooting angle of the three-dimensional contour detector 51, that is, the range of the scanning area 52 (the range shown in the scanning area 52 is the range that the three-dimensional contour detector 51 can scan). Specifically, the hollow servo motor 42 is started, so that the extended end of the hollow servo motor 42 drives the mounting bracket 44 to rotate at a certain angle, thereby realizing the adjustment of the range of the scanning area 52 to meet the detection needs.

[0079] After the inspection is completed, the three-dimensional contour detector 51 can be reset by the joint module 37 and the hollow servo motor 42.

[0080] Furthermore, the present invention also provides a detection method for a surface wear condition detector for slab / rectangular billet crystallizers, comprising the following steps:

[0081] S1: Place the base above the slab / rectangular billet crystallizer 6;

[0082] S2: Start the electric cylinder 23 to adjust the connecting plate 24 to a horizontal state. At this time, the rotating mechanism, the lifting mechanism and the three-dimensional contour detector 51 are in the initial position and there is no deflection.

[0083] S3: Start the linear motion component, so that the linear motion component drives the three-dimensional contour detector 51 to move along the long side of the slab / rectangular billet crystallizer 6, and the three-dimensional contour detector 51 detects the slab / rectangular billet crystallizer 6 until it reaches the corner;

[0084] S4: Start the rotating mechanism to drive the three-dimensional contour detector 51 to rotate 90°, and then drive the three-dimensional contour detector 51 to move along the narrow or wide surface of the slab / rectangular billet crystallizer 6 through the linear motion component until it reaches the next corner;

[0085] S5: Repeat the movements of S3 and S4 until the three-dimensional contour detector 51 has finished detecting the same horizontal plane of the slab / rectangular billet crystallizer 6;

[0086] S6: Start the lifting mechanism to move the 3D contour detector 51 to the next detection plane, and repeat S3-S5 until all detections are completed.

[0087] Furthermore, during the inspection process, the 3D contour detector 51 uploads the collected data to the data processing software for analysis via data acquisition software. The data processing software can graphically display 3D stereoscopic cloud maps, 2D unfolded maps, and 2D slice maps from different viewpoints of the crystallizer. It can also display information such as wear amount, maximum wear amount, taper condition, and foot roller deviation at different locations in data form. Simultaneously, the data processing software can compare the scanning results with those of a brand new crystallizer, a crystallizer with a refurbished state, and the same crystallizer with different throughput rates.

[0088] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Under the concept of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
