Description

Technical Field

[0001] This invention relates to the field of metallurgical technology, and in particular to a method, apparatus, equipment and medium for controlling the tapping of thin slabs. Background Technology

[0002] In the metallurgical industry, a heating furnace is a device (industrial furnace) that heats materials or workpieces (usually metals) to the rolling or forging temperature. On a hot-rolled strip steel production line, the heating furnace area serves as the supplier of heated slabs to the rolling line, and the continuous supply of qualified hot slabs is a prerequisite for stable production on the rolling line.

[0003] During the rolling mill production process, occasionally substandard slabs that do not meet quality requirements will appear. In order to save resources, these substandard slabs will be sent back to the heating furnace for reheating and secondary processing. In addition, sometimes another situation occurs: the slabs after exiting the heating furnace have already been rolled by rough rolling on the rolling mill, meaning the slab thickness has been reduced. However, due to equipment failure in the subsequent process causing a shutdown, the slabs cannot be rolled further and become scrap slabs. These scrap slabs also need to be sent back to the heating furnace for reheating and secondary processing.

[0004] However, since heating furnaces are designed to heat slabs of a fixed thickness (e.g., 237 mm), while substandard slabs are thinner, typically around 100-200 mm (referred to as thin slabs), the tapping of steel after heating these thin slabs requires manual control by the operator. This method has low accuracy and efficiency, and a high risk of error. Therefore, improving the accuracy and efficiency of tapping steel after heating thin slabs is a pressing issue that needs to be addressed. Summary of the Invention

Obviously, the accompanying drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0060] Figure 3 This is a schematic diagram of the structure of an electronic device provided in this application. Detailed Implementation

[0061] This application provides a method for controlling the tapping of thin slabs, which solves the technical problem in the prior art where the tapping of thin slabs after heating in a furnace requires manual control, resulting in low tapping accuracy and efficiency, and a high risk of error.

[0062] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:

[0063] A method for controlling the tapping of thin slabs includes: receiving and responding to a tapping signal of a target slab in a target heating furnace; controlling a walking beam in the target heating furnace to carry the target slab in a positive cyclic motion; monitoring whether the walking beam is in an ascending or high-position state during the positive cyclic motion of the walking beam carrying the target slab; monitoring whether the tapping trigger device of the target heating furnace switches to the target state when the walking beam is in the ascending or high-position state; controlling the tapping trigger device to lock the target state when the tapping trigger device switches to the target state; and controlling the tapping machine of the target heating furnace to perform a tapping action on the target slab while the tapping trigger device is locked in the target state.

[0064] In this embodiment, upon receiving the tapping signal for the target slab, the walking beam is controlled to carry the target slab in a positive cycle to prepare for tapping. During the positive cycle, the walking beam is monitored to see if it is in an ascending or high-position state. When the walking beam is detected to be in an ascending or high-position state, the tapping trigger device is continuously monitored to see if it switches to the target state. When the tapping trigger device switches to the target state, the target state is locked, and the tapping machine is controlled to tap the target slab. Therefore, this embodiment can automatically tap the thin slab after receiving the tapping signal for the target slab, avoiding manual tapping by operators, thereby improving the accuracy and efficiency of tapping thin slabs, reducing the risk of human error, and providing a foundation for improving the rolling rhythm in subsequent processes, thus increasing production efficiency.

[0065] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0066] First, it should be clarified that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0067] During the rolling mill production process, occasionally substandard slabs that do not meet quality requirements will appear. To save resources, these substandard slabs are reheated in the heating furnace for secondary processing. However, since the heating furnace is designed to heat thick slabs of a fixed thickness (e.g., 237mm), while substandard slabs are thinner, typically around 100-200mm (referred to as thin slabs), the heating furnace cannot detect them when tapping steel after heating them, thus failing to trigger the tapping signal. This necessitates manual control by operators, which has low accuracy and efficiency, and a high risk of error. Therefore, improving the accuracy and efficiency of tapping steel after heating thin slabs in the heating furnace is a pressing issue that needs to be addressed.

[0068] To address the aforementioned problems, this embodiment provides the following: Figure 1 The method shown is a method for controlling the tapping of thin slabs, which includes steps S11-S14.

[0069] Step S11: Receive and respond to the tapping signal of the target slab in the target heating furnace, and control the walking beam in the target heating furnace to carry the target slab in a positive cycle motion;

[0070] Step S12: During the positive cyclic motion of the walking beam carrying the target slab, monitor whether the walking beam is in an upward state or a high position.

[0071] Step S13: When the walking beam is in the rising state or high position state, monitor whether the steel tapping triggering device of the target heating furnace has switched to the target state.

[0072] Step S14: When the steel tapping trigger device switches to the target state, control the steel tapping trigger device to lock the target state, and while the steel tapping trigger device is locked in the target state, control the steel tapping machine of the target heating furnace to perform the steel tapping action on the target slab.

[0073] The aforementioned thin slab tapping control method provided in this embodiment can be executed by the controller of the heating furnace.

[0074] Regarding step S11, the steel tapping signal of the target slab in the target heating furnace is received and responded to, and the walking beam in the target heating furnace is controlled to carry the target slab in a positive cycle motion.

[0075] The target slab is a slab with a thickness greater than the height difference between the highest position achievable by the walking beam and the tapping trigger device in the target heating furnace. The position of the fixed beam within the target heating furnace is fixed, while the walking beam moves within a vertical range relative to the fixed beam, for example, within a 100mm vertical range, meaning the walking beam's stroke is 200mm. The tapping trigger device, which can initiate the tapping signal, is installed approximately 170mm above the fixed beam. When the walking beam reaches its highest position, the height difference between the walking beam and the tapping trigger device is 70mm. Therefore, the target slab can only meet the condition of switching the tapping trigger device's state if its thickness exceeds 70mm. For example, when the tapping trigger device is a grating device, only when the target slab thickness exceeds 70mm at its highest position can the grating device be blocked, thus triggering the switching of its state.

[0076] The tapping signal can be generated by the operator touching a virtual button on the screen, or it can be generated when the equipment detects that the target slab is about to be tapped. Upon receiving the tapping signal, it means the target slab needs to be tapped. At this point, the walking beam can be controlled to carry the target slab in a forward cycle. A forward cycle refers to the walking beam moving from the loading end to the tapping end through a rectangular motion of rising, forward, falling, and backward, thus completing one cycle.

[0077] In addition, when a tapping signal is received, the background color of the display device of the target heating furnace can be changed to remind the operator that the current tapping is thin slab tapping, that is, the current tapping mode is thin slab tapping mode.

[0078] Regarding step S12, during the positive cyclic motion of the walking beam carrying the target slab, monitor whether the walking beam is in an upward state or a high-position state.

[0079] The position of the walking beam can be detected by a displacement sensor. During the positive cycle of the walking beam carrying the target slab, the beam rises and moves forward, gradually moving the slab out of the furnace. Monitoring whether the walking beam is in an upward or high-position state during this process includes steps S121-123.

[0080] Step S121: Monitor whether the walking beam is higher than the fixed beam of the target heating furnace;

[0081] Step S122: When the stepping beam is higher than the fixed beam, monitor whether the height difference between the stepping beam and the fixed beam exceeds the preset distance;

[0082] Step S123: When the height difference between the stepping beam and the fixed beam exceeds the preset distance, it is determined that the stepping beam is in an ascending state or a high-position state.

[0083] Monitor whether the stepping beam is higher than the fixed beam. When the stepping beam is higher than the fixed beam, it means that the stepping beam is in the upper position. At this time, it is possible to monitor whether the height difference between the stepping beam and the fixed beam exceeds the preset distance. The preset distance can be set according to the actual situation, such as 10mm, 22mm, 34mm, etc.

[0084] When the walking beam is higher than the fixed beam by a preset distance, the state of the walking beam at this time can be defined as being in an ascending state or a high-position state.

[0085] Regarding step S13, when the walking beam is in the rising state or high position state, monitor whether the steel tapping trigger device of the target heating furnace has switched to the target state.

[0086] When the walking beam is in the rising or high-position state, it can monitor whether the tapping triggering device of the target heating furnace has switched to the target state, or in other words, whether the tapping triggering device is triggered by the target slab. When the tapping triggering device is a grating device, it can monitor whether the grating device is in a state where the light signal is blocked due to the presence of the target slab (i.e., the target state). For example, the initial state of the tapping triggering device is marked as 0, and its mark can be 1 after switching to the target state.

[0087] After the walking beam is in the rising or high position, monitor whether the steel output triggering device has switched to the target state. That is, execute step S13 first and then step S14. This can shorten the time for monitoring the steel output triggering device and save the monitoring resources of step S14.

[0088] Regarding step S14, when the steel tapping triggering device switches to the target state, the steel tapping triggering device is controlled to lock the target state, and while the steel tapping triggering device is locked in the target state, the steel tapping machine of the target heating furnace is controlled to perform the steel tapping action on the target slab.

[0089] When the tapping trigger device switches to the target state, it means that a thin slab (i.e., the target slab) has arrived in the target heating furnace and needs to be tapped. At this time, it is necessary to lock the current target state of the tapping trigger device. If the tapping trigger device is not locked at this time, when the walking beam carries the target slab in positive circulation, it will not be able to trigger the state change condition of the tapping trigger device when the walking beam is in a low position. In this case, the tapping trigger device will think that there is no slab in the heating furnace that needs to be tapped, and thus cannot start the subsequent tapping machine operation. Therefore, once the tapping trigger device is detected to have switched to the target state, it is necessary to lock the current target state of the tapping trigger device.

[0090] In addition, sometimes the tapping triggering device may be mistakenly triggered by iron oxide scale to switch to the target state, but there is no target slab to be tapped at this time. If the tapping triggering device is locked in this situation, it will cause a production accident. Therefore, in order to reduce the impact of such false triggering, when the tapping triggering device switches to the target state, the duration of the switch to the target state can be monitored to see if it exceeds a first preset time. When the duration of the switch to the target state exceeds the first preset time, the tapping triggering device is controlled to lock to the target state. The first preset time can be 0.5 seconds, 1 second, 1.5 seconds, 2 seconds, etc.

[0091] That is, only after the steel tapping triggering device maintains the target state for the first preset time is it considered that the current steel tapping triggering device is in the target state because it is triggered by the target slab, and thus the target state of the steel tapping triggering device can be locked.

[0092] In addition, iron oxide scale may adhere to the tapping trigger device, causing it to remain in the target state for an extended period beyond a preset time. This can lock the target state of the tapping trigger device. To address this false triggering issue, this embodiment continuously monitors for abnormal trigger signals while the target state of the tapping trigger device is locked. Upon receiving an abnormal trigger signal, the device is switched from the target state to the initial state. The abnormal trigger signal can be manually generated by the operator or generated by analyzing image data captured by a camera inside the target heating furnace. This reduces the likelihood of the tapping trigger device being falsely locked due to iron oxide scale, increasing the probability of normal tapping of the target slab.

[0093] While the tapping triggering device is locked in the target state, the tapping machine of the target heating furnace is controlled to perform the tapping action on the target slab. That is, the walking beam will gradually transport the target slab to the direction of the tapping machine, and the tapping machine will transport the target slab from inside the target heating furnace to outside the furnace. During the process of controlling the tapping machine of the target heating furnace to perform the tapping action on the target slab, it is monitored whether the tapping machine in the target heating furnace generates a retraction signal. When the tapping machine generates a retraction signal, the tapping triggering device is controlled to switch from the target state to the initial state.

[0094] When the tapping machine generates a reverse signal, it means that the tapping machine has begun to transport the target slab outside the furnace. At this time, the walking beam can prepare to transport the next slab. To ensure the target slab is transported further away from the target furnace when the tapping machine generates a reverse signal, the duration of the reverse signal can be monitored to see if it exceeds a second preset duration. If the duration exceeds the second preset duration, the tapping triggering device is controlled to switch from the target state to the initial state. The second preset duration can be set according to the production rhythm of subsequent processes in the target furnace. If the subsequent processes require a tighter slab production rhythm, the second preset duration can be shorter; if the subsequent processes require a looser slab production rhythm, the second preset duration can be longer. For example, the second preset duration can be 0.3 seconds, 0.8 seconds, 1.2 seconds, 1.5 seconds, etc. The first and second preset durations can be equal or unequal.

[0095] In summary, this embodiment, upon receiving the tapping signal for the target slab, controls the walking beam to carry the target slab in a positive cycle to prepare for tapping. During the positive cycle, it monitors whether the walking beam is in an ascending or high-position state. When the walking beam is detected to be in an ascending or high-position state, it continues to monitor whether the tapping trigger device switches to the target state. When the tapping trigger device switches to the target state, it locks the target state and controls the tapping machine to tap the target slab. Therefore, this embodiment can automatically tap the thin slab after receiving the tapping signal for the target slab, avoiding manual tapping by operators, thereby improving the accuracy and efficiency of thin slab tapping, reducing the risk of human error, and providing a foundation for improving the rolling rhythm in subsequent processes, thus increasing production efficiency.
