The continuous casting slab sample edge slag removal processing method comprises the following steps: when the switch striker contacts the proximity switch within a preset time, the first driving mechanism drives the punch to move upward, and the workbench drives the clamp to move to a station; when the switch striker does not contact the proximity switch within a preset time, the first driving mechanism drives the punch to move upward along the vertical direction, and the second driving mechanism drives the second driving mechanism to move along the horizontal direction. When the excessive edge slag is punched and cut, the position of the punch is changed to reduce the material resistance from the continuous casting slab sample itself, the acting force of the punch is more concentrated, the punching and cutting effect of the punch on the excessive edge slag on the continuous casting slab sample is improved, and the whole process automation of the continuous casting slab sample edge slag removal processing is realized.

Description

Technical Field

[0001] This invention relates to the field of billet testing technology, and more specifically, to a method for removing edge slag from continuously cast slab samples. Background Technology

[0002] During steel production, steel mills must conduct low-magnification inspections on steel products. This involves analyzing the location, size, composition, and morphology of minute defects within continuously cast steel billets, such as inclusions, delamination, shrinkage cavities, holes, white spots, bubbles, cracks, and porosity, to determine if the steel meets quality requirements. Simultaneously, the continuous casting process and procedures must be monitored and guided in real time to ensure the production of qualified products.

[0003] Low-magnification specimens of continuously cast slabs are cut from the continuously cast and rolled steel billets using flame cutting, which results in cutting slag at the cutting exit. The cutting slag is not conducive to the processing of low-magnification specimens of continuously cast slabs. Before subsequent processing, the slag needs to be cleaned manually using tools such as hammers, chisels, and drills. However, manual removal is difficult to meet the needs of rapid steel production and testing, and the labor intensity of workers is high, the risk factor is high, and the degree of automation is low. Summary of the Invention

[0004] To at least partially solve the above problems, the present invention provides a method for removing edge slag from continuously cast slab samples. This method is based on a continuously cast slab sample processing device, which includes a punch, a first driving mechanism, a second driving mechanism, a proximity switch, a switch block, a worktable, and a fixture. The first driving mechanism is driven by the punch to move the punch vertically. The second driving mechanism is driven by the first driving mechanism to move the first driving mechanism laterally. The fixture is connected to the worktable and is used to fix the continuously cast slab sample. The proximity switch is connected to the first driving mechanism, and the switch block is connected to the punch. When the punch moves vertically downwards, the switch block gradually approaches the proximity switch until it contacts it. When the punch moves vertically upwards, the switch block releases contact with the proximity switch and gradually moves away from it. The proximity switch is electrically connected to the first driving mechanism, the second driving mechanism, and the worktable.

[0005] The method for removing edge slag from the continuously cast slab sample includes the following steps:

[0006] S1: Fix the continuous casting slab sample using a clamp;

[0007] S2: First, the second driving mechanism drives the first driving mechanism to move laterally, and then the first driving mechanism drives the punch to move vertically, so that the punch punches the molten slag on the edge.

[0008] S3: When the switch block contacts the proximity switch within a preset time, the first drive mechanism drives the punch to move upward, and the worktable moves the fixture one station; when the switch block does not contact the proximity switch within a preset time, the first drive mechanism drives the punch to move vertically upward, and the second drive mechanism drives the second drive mechanism to move horizontally.

[0009] Optionally, when the switch block contacts the proximity switch within a preset time, the proximity switch sends a first signal to the first drive mechanism and the worktable, so that the first drive mechanism drives the punch to move vertically upward and the worktable moves the fixture to the next station.

[0010] If the switch block does not contact the proximity switch within a preset time, the proximity switch sends a second signal to the first drive mechanism and the second drive mechanism, so that the first drive mechanism drives the punch to move vertically upward and the second drive mechanism drives the second drive mechanism to move laterally.

[0011] Optionally, the first driving mechanism includes a first driving device and a first guide seat, the punch is slidably connected to the first guide seat, the first driving device is connected to the second driving mechanism, and the first driving device is drivingly connected to the punch.

[0012] Optionally, the first driving device includes a downward-thrusting cylinder and a cylinder mounting base, the output end of the downward-thrusting cylinder is connected to the punch, and the downward-thrusting cylinder is connected to the second driving mechanism through the cylinder mounting base.

[0013] Optionally, the first guide seat includes a first guide plate and two first limiting plates. The first guide plate is connected to the cylinder mounting seat, and the two first limiting plates are connected to the first guide plate so that a first limiting groove is formed between the two first limiting plates and the first guide plate. The punch is at least partially slidably connected in the first limiting groove.

[0014] Optionally, the proximity switch is connected to one of the first limiting plates via a switch mounting bracket, and the sensing end of the proximity switch faces the first side of the punch, and the switch block is connected to the first side of the punch.

[0015] Optionally, the second drive mechanism includes a second drive device, a second guide seat, and a slide plate. The slide plate is connected to the hydraulic cylinder mounting seat and is slidably connected to the second guide seat. The second drive device is drivenly connected to the slide plate.

[0016] Optionally, the second guide seat includes a second guide plate and two second limiting plates, the two second limiting plates being connected to the second guide plate to form a second limiting groove between the two second limiting plates and the second guide plate, and the slide plate being at least partially slidably connected in the second limiting groove.

[0017] Optionally, the second driving device includes a motor and a lead screw. The motor is connected to the second guide plate, the output shaft of the motor is connected to one end of the lead screw, and the other end of the lead screw is threadedly connected to the slide plate.

[0018] Optionally, the fixture is provided with multiple positioning surfaces, which are respectively used to abut against the side and top surfaces of the continuously cast slab sample.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By connecting the fixture to the worktable, the fixture fixes the continuously cast slab sample to be processed. First, the second drive mechanism drives the first drive mechanism to move laterally, so that the punch reaches the first preset punching position. Then, the first drive mechanism drives the punch to move vertically, so that the punch punches the edge slag. If the proximity switch contacts the switch block within the preset time, it means that the punch has successfully punched the edge slag. The first drive mechanism drives the punch to move upward, so that the punch is lifted and returns to the initial position. The worktable moves the fixture one position to prepare for continuing punching. If the proximity switch does not contact the switch block within the preset time, it means that too much edge slag has melted on the continuously cast slab sample, indicating... If the punch does not complete its punching process, the first drive mechanism drives the punch to move upward back to its initial position. At the same time, the second drive mechanism drives the first drive mechanism to move, so that the punch reaches the second preset punching position. The first drive mechanism then drives the punch downward to continue punching the excess molten edge slag. Since the punch is now far from the molten interface between the edge slag and the continuously cast slab sample, the material resistance encountered from the continuously cast slab sample itself is reduced, making the force of the punch more concentrated and improving the punching effect of the punch on the excess molten edge slag on the continuously cast slab sample. This enables the full automation of the process of removing edge slag from the continuously cast slab sample. Attached Figure Description

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment of the invention provides a method for removing edge slag from a continuously cast slab sample. The method is based on a continuously cast slab sample processing device, which includes a punch 1, a first driving mechanism 2, a second driving mechanism 3, a proximity switch 4, a switch block 5, a worktable 6, and a fixture 7. The first driving mechanism 2 is driven to the punch 1 to move the punch 1 vertically. The second driving mechanism 3 is driven to the first driving mechanism 2 to move the first driving mechanism 2 horizontally. The fixture 7 is connected to the worktable 6 and is used to fix the continuously cast slab sample 100. The proximity switch 4 is connected to the first driving mechanism 2, and the switch block 5 is connected to the punch 1. When the punch 1 moves vertically downward, the switch block 5 gradually approaches the proximity switch 4 until it contacts the proximity switch 4. When the punch 1 moves vertically upward, the switch block 5 releases contact with the proximity switch 4 and gradually moves away from the proximity switch 4. The proximity switch 4 is electrically connected to the first driving mechanism 2, the second driving mechanism 3, and the worktable 6.

[0034] The method for removing edge slag from continuously cast slab samples includes the following steps:

[0035] S1: Fix the continuous casting slab sample 100 using clamp 7;

[0036] S2: First, the second driving mechanism 3 drives the first driving mechanism 2 to move laterally, and then the first driving mechanism 2 drives the punch 1 to move vertically, so that the punch 1 punches the edge molten slag 110.

[0037] S3: When the switch block 5 contacts the proximity switch 4 within a preset time, the first drive mechanism 2 drives the punch 1 to move upward, and the worktable 6 drives the fixture 7 to move one station; when the switch block 5 does not contact the proximity switch 4 within a preset time, the first drive mechanism 2 drives the punch 1 to move vertically upward, and the second drive mechanism 3 drives the second drive mechanism 3 to move horizontally.

[0038] Specifically, punch 1 can be an alloy punch, such as a high-speed steel punch or a tungsten steel punch; fixture 7 can be a mechanical fixture, a vacuum adsorption fixture, a magnetic fixture, a custom fixture, etc. The first drive mechanism 2 and the second drive mechanism 3 are both linear drive mechanisms, such as screw drive devices, gear drive, hydraulic drive, etc. Multiple fixtures 7 are connected on the worktable 6 to process multiple continuously cast slab samples 100 in turn. The worktable 6 is a processing line that can receive system instructions to drive the worktable 6 to move, thereby changing the position of fixture 7; the first drive mechanism 2 drives punch 1 to move vertically, which refers to the Z-axis direction in the figure, and the second drive mechanism 3 drives the first drive mechanism 2 to move horizontally, which refers to the X-axis direction in the figure.

[0039] In this embodiment, by connecting the fixture 7 to the worktable 6, the fixture 7 fixes the continuously cast slab sample 100 to be processed. First, the second driving mechanism 3 drives the first driving mechanism 2 to move laterally, so that the punch 1 reaches the first preset punching position. Then, the first driving mechanism 2 drives the punch 1 to move vertically, so that the punch 1 punches the edge slag 110. If the proximity switch 4 contacts the switch block 5 within a preset time, it means that the punch 1 has successfully punched the edge slag 110. The first driving mechanism 2 drives the punch 1 to move upward, so that the punch 1 is lifted and returns to the initial position. The worktable 6 drives the fixture 7 to move one station to prepare for continuing punching. If the proximity switch 4 does not contact the switch block 5 within the preset time, it means that too much edge slag 110 has melted in the continuously cast slab sample 100. This indicates that punch 1 has not completed its punching process. The first drive mechanism 2 drives punch 1 to move upward back to its initial position. At the same time, the second drive mechanism 3 drives the first drive mechanism 2 to move, so that punch 1 reaches the second preset punching position. The first drive mechanism 2 then drives punch 1 to move downward to continue punching the excess edge slag 110. Since punch 1 is now far from the molten connection between the edge slag 110 and the continuous casting slab sample 100 at the punching position, the material resistance encountered from the continuous casting slab sample 100 itself is reduced, making the force of punch 1 more concentrated and improving the punching effect of punch 1 on the excess edge slag 110 on the continuous casting slab sample 100. This enables the full automation of the process of removing edge slag 110 from the continuous casting slab sample 100.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, when the switch block 5 contacts the proximity switch 4 within a preset time, the proximity switch 4 sends a first signal to the first drive mechanism 2 and the worktable 6, so that the first drive mechanism 2 drives the punch 1 to move vertically upward and the worktable 6 drives the fixture 7 to move to the next station.

[0041] When the switch block 5 does not contact the proximity switch 4 within a preset time, the proximity switch 4 sends a second signal to the first drive mechanism 2 and the second drive mechanism 3, so that the first drive mechanism 2 drives the punch 1 to move vertically upward and the second drive mechanism 3 drives the second drive mechanism 3 to move horizontally.

[0042] Based on this embodiment, a method for processing continuously cast slab samples is provided, including:

[0043] The continuous casting slab sample 100 is fixed by clamp 7;

[0044] The second driving mechanism 3 drives the first driving mechanism 2 to move, so that the punch 1 reaches the first preset punching position. The first preset punching position is a distance a from the punch 1 to the wide side of the continuous casting slab sample 100.

[0045] The first drive mechanism 2 drives the punch 1 downward, causing the punch 1 to punch the edge slag 110. If, during the downward punching, the proximity switch 4 contacts the switch block 5 within a preset time, it indicates that the punch 1 has successfully punched the edge slag 110. The proximity switch 4 sends a first signal to the first drive mechanism 2 and the worktable 6. The first drive mechanism 2 then drives the punch 1 upward, lifting it back to its initial position. The worktable 6 moves the fixture 7 one position to prepare for continued punching. If, within the preset time, the proximity switch 4 does not contact the switch block 5, it indicates that too much edge slag 110 has melted in the continuously cast slab sample 100, meaning the punching is incomplete. The proximity switch 4 sends a second signal to the first drive mechanism 2 and the second drive mechanism 3. The second drive mechanism 3 drives the first drive mechanism 2 to move, causing the punch 1 to reach a second preset punching position. The second preset punching position is based on the first preset punching position but continues away from the wide edge of the continuously cast slab sample 100, for example, at... Figure 5 If the punch moves further away from the distance b, the second preset punching position is the distance a+b between the punch 1 and the 100-width side of the continuous casting slab sample. Then the first drive mechanism 2 drives the punch 1 to move downward to complete the punching.

[0046] In the subsequent punching process, the punch 1 is kept in the first preset punching position to continue punching. The entire punching process will be repeated depending on the melting of the edge slag 110 on the continuously cast slab sample 100.

[0047] The following example illustrates the processing method of the continuously cast slab sample described above, combined with its application in actual production. The width data of the continuously cast slab sample 100 has been input into the system before processing. The side and top surfaces of the continuously cast slab sample 100 are pressed together using the positioning surface in the fixture 7. The second drive mechanism 3 drives the first drive mechanism 2 to move, causing the punch 1 to reach the first preset punching position. This first preset punching position is set at a distance of 2mm from the wide side of the continuously cast slab sample 100. This 2mm distance is equivalent to... Figure 4 At distance a, the lowering cylinder 21 drives the punch 1 to punch the edge slag 110. When the punch 1 punches downwards, the preset time can be set to 5 seconds. That is, if the proximity switch 4 contacts the switch block 5 mounted on the punch 1 within 5 seconds, it indicates that the punch 1 has successfully punched the edge slag 110. The punch 1 then lifts back to its initial position, and the worktable 6 moves the fixture 7 one position to prepare for continued punching. If, during the downward punching, the proximity switch 4 does not contact the switch block 5 within 5 seconds, it indicates that too much edge slag 110 has melted in the continuously cast slab sample 100, and the punch 1 has not completed the punching. At this time, the second driving mechanism 3 drives the first driving mechanism 2 to move, causing the punch 1 to reach the second preset punching position. The second preset punching position is a distance of 2mm + 0.5mm from the wide side of the continuously cast slab sample 100. This 2mm + 0.5mm distance is equivalent to... Figure 5 At a distance of a+b, the punch 1 is positioned closer to the side of the edge slag 110 away from the continuously cast slab sample 100. In other words, the punching position of the edge slag 110 is moved away from the molten connection with the continuously cast slab sample 100, improving the punching effect of the punch 1 on the excessively molten edge slag 110 on the continuously cast slab sample 100. During subsequent punching operations, the lower punch cylinder 21 will move to a position 2mm behind the width of the continuously cast slab sample 100 to continue punching, ensuring that the entire punched surface remains neat after processing. The process involves repeating the above steps depending on the melting condition of the edge slag 110 on the continuously cast slab sample 100. It should be noted that the punch 1 is not limited to the first preset punching position and the second preset punching position. The specific position can be determined based on the melting condition of the edge slag 110. When a large amount of edge slag 110 has melted, multiple punching operations are required. In this case, the punch 1 can be used at the third preset punching position, the fourth preset punching position, etc. This processing method enables the full automation of the process of removing the edge slag 110 from the continuously cast slab sample 100.

[0048] like Figure 1 and Figure 3 As shown, optionally, the first driving mechanism 2 includes a first driving device and a first guide seat, the punch 1 is slidably connected to the first guide seat, the first driving device is connected to the second driving mechanism 3, and the first driving device is drivingly connected to the punch 1.

[0049] In this embodiment, the first driving device is moved by the second driving mechanism 3, thereby driving the punch 1 to move along the first guide seat, so as to realize the punching operation on the edge slag 110.

[0050] like Figure 1 and Figure 3 As shown, optionally, the first driving device includes a lower punch cylinder 21 and a cylinder mounting base 22. The output end of the lower punch cylinder 21 is connected to the punch 1, and the lower punch cylinder 21 is connected to the second driving mechanism 3 through the cylinder mounting base 22.

[0051] In this embodiment, the output rod of the lower punch cylinder 21, i.e., the outer end of the piston rod, is connected to the punch 1. The lower punch cylinder 21 is fixedly mounted on the second drive mechanism 3 through the cylinder mounting seat 22. Thus, under the driving action of the first drive mechanism 2, the second drive mechanism 3 can drive the cylinder mounting seat 22 to move, thereby driving the lower punch cylinder 21 to move, and thus enabling the punch 1 to move synchronously.

[0052] like Figure 1 and Figure 3 As shown, optionally, the first guide seat includes a first guide plate 23 and two first limiting plates 24. The first guide plate 23 is connected to the cylinder mounting seat 22, and the two first limiting plates 24 are connected to the first guide plate 23 so that a first limiting groove is formed between the two first limiting plates 24 and the first guide plate 23. The punch 1 is at least partially slidably connected in the first limiting groove.

[0053] In this embodiment, the two first limiting plates 24 can be fixed to the first guide plate 23 by welding or threaded connection, or they can be integrally formed with the first guide plate 23. The two first limiting plates 24 can be symmetrical about the first guide plate 23. The first guide plate 23 can be a flat plate structure, and the two first limiting plates 24 can be an L-shaped structure, so that the two first limiting plates 24 and the first guide plate 23 together form a rectangular space second limiting groove. The extension direction of the second limiting groove is along the vertical direction, that is, along the Z-axis direction in the figure. At least a part of the punch 1 is integrally formed as a part that slides and cooperates with the second limiting groove, so that the punch 1 can reciprocate in the vertical direction under the limiting and guiding action of the second limiting groove.

[0054] like Figure 2 As shown, the proximity switch 4 is connected to one of the first limiting plates 24 via a switch mounting bracket, and the sensing end of the proximity switch 4 faces the first side of the punch 1. The switch block 5 is connected to the first side of the punch 1.

[0055] Specifically, the proximity switch 4 can be mounted on the first limiting plate 24 by a switch bracket and screws to facilitate the installation and removal of the proximity switch 4 and improve maintenance and replacement efficiency. Since the first limiting plate 24, which is located on the inner side, may be relatively close to the machine frame of the processing line after installation, it may cause inconvenience in the installation and removal of the proximity switch 4. In order to facilitate the installation and removal process of the proximity switch 4, the proximity switch 4 is mounted on the first limiting plate 24, which is located on the outer side.

[0056] like Figure 1 and Figure 3 As shown, optionally, the second drive mechanism 3 includes a second drive device, a second guide seat and a slide plate 33. The slide plate 33 is connected to the cylinder mounting seat 22, the slide plate 33 is slidably connected to the second guide seat, and the second drive device is drivenly connected to the slide plate 33.

[0057] In this embodiment, the hydraulic cylinder mounting base 22 can be fixedly mounted on the slide plate 33 by screws. The slide plate 33 is driven to move on the second guide seat by the second drive device, thereby driving the hydraulic cylinder mounting base 22 to move synchronously. The movement of the hydraulic cylinder mounting base 22 in turn drives the lower punch cylinder 21 to move synchronously, and finally realizes the movement of the punch 1, so that the position of the punch 1 can be changed.

[0058] like Figure 1 and Figure 3 As shown, optionally, the second guide seat includes a second guide plate 34 and two second limiting plates 35. The two second limiting plates 35 are connected to the second guide plate 34 so that a second limiting groove is formed between the two second limiting plates 35 and the second guide plate 34, and the slide plate 33 is at least partially slidably connected in the second limiting groove.

[0059] In this embodiment, the two second limiting plates 35 can be fixed to the second guide plate 34 by welding or threaded connection, or they can be integrally formed with the second guide plate 34. The two second limiting plates 35 can be symmetrical about the second guide plate 34. The cross-section of the second guide plate 34 can be C-shaped. The two second guide plates 34 can be flat plate structures. At least a portion of the two second limiting plates 35 extends into the second guide plate 34, so that the two second limiting plates 35 and the second guide plate 34 together form a second limiting groove for the slide plate 33 to slide. The extension direction of the second limiting groove is horizontal, that is, along the X-axis direction, so that the slide plate 33 can slide in the second limiting groove.

[0060] like Figure 1 and Figure 3 As shown, optionally, the second driving device includes a motor 31 and a lead screw 32. The motor 31 is connected to the second guide plate 34, the output shaft of the motor 31 is connected to one end of the lead screw 32, and the other end of the lead screw 32 is threadedly connected to the slide plate 33.

[0061] In this embodiment, the motor 31 can be bolted to the second guide plate 34 or installed at the corresponding position on the frame of the processing line. The output shaft of the motor 31 is connected to one end of the lead screw 32 through a coupling. The slide plate 33 has a threaded through hole, and the lead screw 32 is threaded into the threaded through hole. The motor 31 receives the signal from the system and drives the lead screw 32 to rotate in both directions, thereby driving the slide plate 33 to move back and forth. That is, it drives the slide plate 33 to move back and forth along the X-axis. Specifically, when the slide plate 33 moves along the positive X-axis, it drives the punch 1 to move towards the edge slag 110. When the slide plate 33 moves along the negative X-axis, it drives the punch 1 to move away from the edge slag 110.

[0062] like Figure 1 and Figure 3 As shown, optionally, the fixture 7 is provided with multiple positioning surfaces, which are respectively used to abut against the side and top surfaces of the continuously cast slab sample 100.

[0063] In this embodiment, the clamp 7 has a slot for accommodating the continuously cast slab sample 100. A portion of the positioning surface is located on the side of the slot, and another portion of the positioning surface is located on the side of the clamp 7 for pressing the side of the continuously cast slab sample 100 away from the edge slag 110. The other portion of the positioning surface is located on the top of the slot for pressing the top surface of the continuously cast slab sample 100, thereby limiting and fixing the continuously cast slab sample 100.

[0064] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
