Description

Technical Field

[0001] This application relates to the field of metallurgical technology, and in particular to a method, apparatus, equipment and medium for detecting the removal of cutting marks on cast billets. Background Technology

[0002] After flame cutting, a cutting nodule is left on the outer arc side of the continuously cast billet. If the cutting nodule is too large, it can cause steel piling problems during the rolling process, resulting in defects such as peeling, scaling, and delamination at the beginning and end. Therefore, the cutting nodule must be removed using a cutting nodule removal device after cutting.

[0003] In the prior art, in order to detect the removal effect of the cutting edge, the lower surface of the cast billet is usually visually inspected to determine whether the cutting edge has been completely removed.

[0004] However, the surface temperature of the billet is high, and personnel need to observe the lower surface of the billet from a distance. This makes it difficult to accurately check whether the cutting edge has been completely removed by visual inspection, and increases the risk of defects such as peeling on the surface of the coil caused by pressing into the coil surface during the rolling process. Summary of the Invention

[0005] In view of the above problems, this application is made to provide a method, apparatus, equipment and medium for detecting the removal of cutting marks on the lower surface of the billet, which can confirm whether the cutting marks on the lower surface of the billet have been removed through dual detection, and can detect whether the cutting marks have been removed more accurately, thereby improving the rolling quality.

[0006] Firstly, this application provides a method for detecting the removal of slab cutting marks, applied to a slab cutting mark removal detection system, the method comprising: After performing the cutting edge removal operation on the lower surface of the billet, if a cutting edge detection device sends a signal indicating that the cutting edge has not been removed, the cutting edge removal status of the billet is adjusted to a pending confirmation status, and an early warning is issued. The cutting edge not removed signal is sent by the cutting edge detection device to the cutting edge removal status detection system after the cutting edge removal operation is performed on the lower surface of the billet and a cutting edge is detected on the lower surface of the billet. After the warning is issued, if a confirmation signal is received that the cutting edge of the billet has not been removed, the cutting edge removal status of the billet will be adjusted to the unremoved status.

[0007] Optionally, after adjusting the state of the cut-off mark removal of the cast billet to a state awaiting confirmation, the method further includes: The status of the cutting nodule removal device is adjusted to an abnormal state, and the cutting nodule removal device is used to perform the cutting nodule removal operation.

[0008] Optionally, the cutting edge detection device includes a probe and a detection circuit. The probe is arranged below the lower surface of the billet, and the central axis of the probe is parallel to the lower surface of the billet and at a set distance. The probe is used to cause the detection circuit to generate a signal indicating that the cut-off mark has not been removed when it comes into contact with a cut-off mark on the lower surface of the billet.

[0009] Optionally, the method further includes: The set distance is determined based on the size of the cutting nodule.

[0010] Optionally, after performing the cutting edge removal operation on the lower surface of the cast billet, the method further includes: If no signal indicating that the cut-off not has been removed is received from the cut-off detection device, the cut-off removal status of the billet is adjusted to the removed status.

[0011] Optionally, after performing the cutting edge removal operation on the lower surface of the billet, if a cutting edge detection device sends a signal indicating that the cutting edge has not been removed, the cutting edge removal status of the billet is adjusted to a pending confirmation status, including: Obtain the average interval time from the time the billet leaves the production line to the rolling process; If the average interval time is greater than the preset time threshold, and after performing the cutting edge removal operation on the lower surface of the billet, a cutting edge detection device sends a signal indicating that the cutting edge has not been removed, then the cutting edge removal status of the billet is adjusted to a pending confirmation status.

[0012] Optionally, after issuing a warning, the method further includes: If a confirmation signal indicating that the cutting edge of the billet has been removed is received, the cutting edge removal status of the billet is adjusted to the removed status.

[0013] Secondly, this application provides a device for detecting the removal of slab cutting marks, applied to a slab cutting mark removal detection system, the device comprising: The first adjustment module is used to adjust the cutting edge removal status of the billet to a pending confirmation status and issue an early warning if it receives a cutting edge detection signal that the cutting edge has not been removed after performing the cutting edge removal operation on the lower surface of the billet; the cutting edge not removed signal is sent by the cutting edge detection device to the cutting edge removal status detection system after performing the cutting edge removal operation on the lower surface of the billet and detecting the presence of cutting edge on the lower surface of the billet. The second adjustment module is used to adjust the cutting edge removal status of the billet to an unremoved status if a confirmation signal of unremoved cutting edge is received after an early warning.

[0014] Thirdly, this application provides an electronic device, including: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the computer instructions to perform the method as described in the first aspect.

[0015] Fourthly, this application provides a computer-readable storage medium storing computer instructions for causing the computer to perform the method described in the first aspect.

[0016] The technical solutions provided in this application embodiment have at least the following technical effects or advantages: This application provides a method, apparatus, device, and medium for detecting the removal of cutting nodules on a cast billet. After performing a cutting nodule removal operation on the lower surface of the cast billet, if a cutting nodule removal signal is received from a cutting nodule detection device, the cutting nodule removal status of the cast billet is adjusted to a pending confirmation state, and an early warning is issued. The cutting nodule removal signal is sent to the cutting nodule removal detection system by the cutting nodule detection device after performing the cutting nodule removal operation on the lower surface of the cast billet. That is, when the cutting nodule detection device detects that there are still cutting nodules on the lower surface of the cast billet after the cutting nodule removal operation has been performed, the cutting nodule removal status of the cast billet is adjusted to a pending confirmation state so that it can enter the secondary confirmation stage. After the early warning, if a confirmation signal of unremoved cutting nodule is received, the cutting nodule removal status of the cast billet is adjusted to an unremoved state. That is, after secondary confirmation, if it is found that there are indeed cutting nodules on the lower surface of the cast billet, the cutting nodule removal status of the cast billet is adjusted to an unremoved state so that the workers can deal with the cast billet in the unremoved state to avoid quality problems caused by direct rolling. This method can confirm whether the cutting edge on the lower surface of the billet has been removed through dual detection, which can more accurately detect whether the cutting edge has been removed, thereby improving the rolling quality.

[0017] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, the same reference numerals denote the same parts throughout the drawings. In the drawings: Figure 1This is a flowchart of a method for detecting the removal of cutting marks on a cast billet, as provided in an embodiment of this application. Figure 2 This is a structural block diagram of a device for detecting the removal of cutting marks on a cast billet, provided in an embodiment of this application. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. It should be understood that the embodiments of this disclosure and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. Unless otherwise specified, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0020] Figure 1 This is a flowchart of a method for detecting the removal of cutting marks on a cast billet, as provided in an embodiment of this application. Figure 1 As shown, this method is applied to a tumor removal detection system, including: Step S110: After performing the cutting edge removal operation on the lower surface of the billet, if a cutting edge detection device sends a signal indicating that the cutting edge has not been removed, the cutting edge removal status of the billet is adjusted to a pending confirmation status, and an early warning is issued.

[0021] Among them, the signal of unremoved cutting edge is sent to the cutting edge removal detection system when the cutting edge detection equipment detects cutting edge on the lower surface of the billet after performing the cutting edge removal operation.

[0022] In this embodiment, the sprue removal detection system is used to detect the removal status of sprue granules on the lower surface of the billet. The sprue granule detection device is used to detect whether there are sprue granules on the lower surface of the billet. The sprue granule removal device is used to perform the sprue granule removal operation to remove the sprue granules. The sprue granule detection device is arranged downstream of the sprue granule removal device, so that the billet passes through the sprue granule removal device first and then passes through the sprue granule detection device, so that the sprue granules are removed first, and then the billet after removal is detected to have any remaining sprue granules.

[0023] This can be understood as follows: after the cutting edge removal operation is performed on the lower surface of the billet, the cutting edge detection equipment detects whether there is a cutting edge on the lower surface of the billet, that is, whether the cutting edge on the lower surface of the billet has been removed; if the cutting edge detection equipment detects a cutting edge on the lower surface of the billet, it generates a cutting edge not removed signal and sends the cutting edge not removed signal to the cutting edge removal status detection system; if the cutting edge removal status detection system receives the cutting edge not removed signal sent by the cutting edge detection equipment, it adjusts the cutting edge removal status of the billet to a pending confirmation status and issues an early warning.

[0024] The early warning system includes sending alarm information to the primary control system, which then displays the alarm information on its screen. The alarm information serves to remind workers that the cutting edge on the lower surface of the cast billet has not been removed. The alarm information includes information about the unremoved cutting edge and an identifier for the cast billet from which the cutting edge was not removed; that is, the screen displays which cast billet has the unremoved cutting edge on its lower surface.

[0025] Step S120: After the warning, if a confirmation signal that the cutting edge of the billet has not been removed is received, the cutting edge removal status of the billet is adjusted to the unremoved status.

[0026] In this embodiment, after an early warning, staff will be informed that the cutting edge on the lower surface of the billet has not been removed. At this point, staff will conduct a secondary verification to confirm the removal status. If staff detects that the cutting edge is indeed present on the lower surface of the billet, a confirmation signal is triggered. If the cutting edge removal detection system receives this signal, it adjusts the billet's cutting edge removal status to "not removed," marking the billet as having an unremoved cutting edge. This allows staff to perform special processing on billets in this unremoved state to prevent rolling quality issues during rolling. This method uses dual detection to confirm whether the cutting edge on the lower surface of the billet has been removed, providing more accurate detection and improving rolling quality. Staff can trigger the confirmation signal by pressing a pre-set button or through other methods.

[0027] The adjusted removal status of the cutting edge can be sent to the three-level control system, which then forwards it to the quality assessment system. Staff members confirm and handle the removal status of the cutting edge based on the assessment results of the quality assessment system.

[0028] Optionally, after step S110, the method includes: Adjust the status of the tumor removal equipment to abnormal state.

[0029] In this embodiment, after the removal of the cutting edge on the lower surface of the billet, if the cutting edge removal detection system receives a signal from the cutting edge detection device indicating that the cutting edge has not been removed, it suspects that the failure to remove the cutting edge is due to a malfunction of the cutting edge removal device. Therefore, the status of the cutting edge removal device is adjusted to an abnormal state so that personnel can inspect the abnormal cutting edge removal device. If the cutting edge removal device does indeed have a problem, it is repaired. This method determines the status of the cutting edge removal device by assessing the cutting edge removal status, reducing the problems of plate and coil defects and increased costs caused by incomplete cutting edge removal.

[0030] Optionally, the cutting edge detection device includes a probe and a detection circuit. The probe is arranged below the lower surface of the billet, and the central axis of the probe is parallel to the lower surface of the billet and at a set distance. The probe is used to generate a signal that the cut-off mark has not been removed when it comes into contact with the cut-off mark on the lower surface of the billet.

[0031] In this embodiment, a probe of a burr detection device is used to detect whether there are burrs on the lower surface of the billet. In one implementation, the probe has a retractable spring structure at its tail end. If there are burrs on the lower surface of the billet, the probe retracts after contacting the burr. The retracted tail end of the probe pushes a conductive mechanism (such as a spring or contact) in the detection circuit to move. After moving to a certain extent, the conductive mechanism causes the two originally separate conductive contacts in the detection circuit to close, making the detection circuit conductive. The conductive circuit generates a burr removal signal. If there are no burrs on the lower surface of the billet, there is no retracted probe, the detection circuit will not be conductive, and no burr removal signal will be generated. The principle of this burr detection device can be understood as similar to that of a limit switch.

[0032] In another implementation: the probe is a tiny elastic body with a strain gauge attached to its tip (the resistance value changes with material deformation). When the probe tip touches the cut-off mark with a very small force, the probe bends. This bending causes a change in the resistance value of the strain gauge. After the detection circuit detects this tiny resistance change, it converts the resistance change into a voltage change signal. When the voltage value exceeds a preset threshold, a cut-off mark not removed signal is generated; when the voltage value does not exceed the threshold, no cut-off mark not removed signal is generated.

[0033] Optionally, the set distance can be determined based on the size of the cut end.

[0034] In this embodiment, the size of the cutting mark on the lower surface of the billet can be detected to determine its size. The distance between the probe and the lower surface of the billet is then set according to the size of the cutting mark, ensuring that the probe can reach the cutting mark and avoiding a distance that is too large to reach it. Therefore, the size of the cutting mark can be positively correlated with the set distance.

[0035] For example, the size of the cutting nodule is 5-7mm, and the range of the set distance is set to 3-5mm.

[0036] Optionally, the method also includes: After performing the cutting edge removal operation on the lower surface of the billet, if no cutting edge removal signal is received from the cutting edge detection device, the cutting edge removal status of the billet is adjusted to the removed status.

[0037] In this embodiment of the application, after performing the cutting edge removal operation on the lower surface of the billet, if no cutting edge removal signal is received from the cutting edge detection device, it means that there is no cutting edge on the lower surface of the billet. Then, the cutting edge removal status of the billet is adjusted to the removed status, so that the billet is marked as having removed cutting edge and can be rolled normally.

[0038] Optionally, step S110 includes: The average interval time from the start of billet removal to rolling is obtained; if the average interval time is less than the preset time threshold, and after the removal of the cutting edge on the lower surface of the billet is performed, a signal indicating that the cutting edge has not been removed is received from the cutting edge detection device, then the cutting edge removal status of the billet is adjusted to the pending confirmation status.

[0039] In this embodiment, as production efficiency improves, the interval between billet removal and rolling becomes increasingly shorter. This short interval makes it impossible for manual inspection of the removal of cutting nodules on the lower surface of each billet. Therefore, the appropriate inspection process can be determined based on the average interval from billet removal to rolling. If the average interval is greater than or equal to a time threshold, it indicates a large average interval, and manual visual inspection is sufficient. If the average interval is less than the time threshold, it indicates a small average interval, and a dual inspection process is used. Specifically, if the average interval is less than the time threshold, and after removing cutting nodules from the lower surface of the billet, a signal indicating that the cutting nodules have not been removed is received from the cutting nodule detection device, the cutting nodule removal status of the billet is adjusted to a pending confirmation state, awaiting manual re-confirmation of whether cutting nodules remain on the lower surface. These two inspection processes allow for more flexible inspection of cutting nodule removal, increasing inspection frequency and efficiency while reducing inspection and production costs.

[0040] Optionally, the method also includes: After the warning is issued, if a confirmation signal indicating that the cutting edge of the billet has been removed is received, the status of the cutting edge removal of the billet will be adjusted to the removed status.

[0041] In this embodiment, after an early warning, if a confirmation signal indicating the removal of cutting marks on the billet is received, it means that during a manual secondary inspection, no cutting marks were found on the lower surface of the billet. Therefore, the confirmation signal is triggered, and the cutting mark removal status of the billet is adjusted to "removed," signifying that the cutting marks have been removed. The cutting mark removal status and identification code of the billet are then sent to the three-level control system and the quality judgment system to achieve automatic transmission and judgment of the inspection results. The operator can trigger the confirmation signal by pressing a designated button or through other means.

[0042] Based on the same concept, embodiments of the present invention also provide a device for detecting the removal of cutting marks on cast billets. Figure 2 This is a structural block diagram of a device for detecting the removal of cutting marks on cast billets, as provided in an embodiment of this application. Figure 2 As shown, the device 200 includes a first adjustment module 201 and a second adjustment module 202.

[0043] The first adjustment module 201 is used to adjust the cutting edge removal status of the billet to a pending confirmation status and issue an early warning if it receives a cutting edge detection signal that the cutting edge has not been removed after performing the cutting edge removal operation on the lower surface of the billet; the cutting edge not removed signal is sent by the cutting edge detection device to the cutting edge removal status detection system after performing the cutting edge removal operation on the lower surface of the billet and detecting the presence of cutting edge on the lower surface of the billet. The second adjustment module 202 is used to adjust the cutting edge removal status of the billet to an unremoved status if a confirmation signal of unremoved cutting edge is received after an early warning.

[0044] Optionally, the device 200 also includes a third adjustment module for: The status of the cutting tip removal equipment is adjusted to an abnormal state, and the cutting tip removal equipment is used to perform the cutting tip removal operation.

[0045] Optionally, the cutting edge detection device includes a probe and a detection circuit. The probe is arranged below the lower surface of the billet, and the central axis of the probe is parallel to the lower surface of the billet and at a set distance. The probe is used to generate a signal that the cut-off mark has not been removed when it comes into contact with the cut-off mark on the lower surface of the billet.

[0046] Optionally, the device 200 also includes a determining module for: Determine the set distance based on the size of the cut end.

[0047] Optionally, the device 200 also includes a fourth adjustment module for: If no signal indicating that the cutting edge has not been removed is received from the cutting edge detection device, the cutting edge removal status of the billet will be adjusted to the removed status.

[0048] Optionally, the first adjustment module 201 is also used for: Obtain the average interval time from the time the billet leaves the production line to the rolling process; If the average interval time is greater than the preset time threshold, and after the cutting edge removal operation is performed on the lower surface of the billet, a cutting edge detection device sends a signal that the cutting edge has not been removed, then the cutting edge removal status of the billet is adjusted to a pending confirmation status.

[0049] Optionally, the device 200 also includes a fifth adjustment module for: If a confirmation signal indicating that the cutting edge of the billet has been removed is received, the status of the cutting edge removal of the billet is adjusted to the removed status.
