Description

Technical Field

[0001] The present invention relates to the field of smelting technology, and in particular to a coiler control method and related equipment. Background Art

[0002] Hot-rolled strip products cover a wide range of varieties and have a large span of thickness specifications. In addition, the production plan needs to be adjusted accordingly as the contract changes, which results in the phenomenon of continuous switching of thin and thick strip production. When the speed difference between the two pieces of steel in front and behind is too large, it will cause the two pieces of steel to "rear-end" accidents, resulting in scrap and production stoppages. In the existing technology, the method of predicting whether the two pieces of steel can catch up with each other is used to avoid "rear-end" accidents. However, it was found through actual production that due to the influence of factors such as temperature control and speed regulation, the method of predicting whether the two pieces of steel can catch up with each other is flawed. That is, if this safety condition limit is met, the rhythm needs to be sacrificed. In the pursuit of efficiency optimization, controlling the finishing steel feed will seriously affect efficiency.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0049] like Figure 1 As shown, a coiler control method according to an embodiment of the present invention specifically includes the following steps:

[0050] S110, monitoring the rolling task of the hot-rolled steel strip. When the rolling task changes and the changed rolling task requires calling a different coiler, the hot-rolled steel strip produced by executing the rolling task before the change is used as the first steel strip, the hot-rolled steel strip produced by executing the changed rolling task is used as the second steel strip, and the coiler corresponding to the first steel strip is used as the first coiler, and the coiler corresponding to the second steel strip is used as the second coiler.

[0051] For example, the rolling task can be understood as a production task for a type of strip steel, and the change in the rolling task can be understood as: the current rolling task (rolling task before the change) is used to produce type A strip steel, and the rolling task after the change is used to produce type B strip steel.

[0052] For example, when the rolling task has not changed, if the currently running coiler fails and stops working, the strip that last entered the failed coiler will be used as the first strip, the newly put into use coiler will be used as the second coiler, and the strip that entered the new coiler will be used as the second strip.

[0053] S120, acquiring a first distance between the final finishing stand and the pinch roller of the second coiler, a second distance between the final finishing stand and the head of the second steel strip, a third distance between the final finishing stand and the pinch roller of the first coiler, and a fourth distance between the final finishing stand and the tail of the first steel strip, and acquiring an output speed of the final finishing stand and a coiling speed of the first coiler;

[0054] Exemplarily, since the finishing rolling last stand is fixed, the finishing rolling last stand is used as a reference to determine the first distance, the second distance, the third distance and the fourth distance.

[0055] S130: Calculate a first time duration for the head of the second strip to arrive at the second coiler based on the first distance, the second distance, and the output speed, and determine a second time duration for the tail of the first strip to enter the first coiler based on the third distance, the fourth distance, and the coiling speed;

[0056] For example, Figure 2 As shown, the mathematical expression for calculating the first time length of the second strip head arriving at the second coiler based on the first distance, the second distance and the output speed is:

[0057] (S i+1精卷 -H 头 ) / V 精 ;

[0058] The mathematical expression for determining the second time duration for the tail of the first strip to enter the first coiler based on the third distance, the fourth distance, and the coiling speed is:

[0059] (S i精卷 -T 尾 ) / V 卷 ;

[0060] Among them, S i+1精卷 : represents the distance between the final stand of the finishing mill and the pinch roll of the i+1 coiler where the next piece of steel is about to enter, i.e., the first distance; H 头 : represents the distance between the finishing stand and the strip head in the figure, i.e., the second distance; V 精 : represents the speed of the final stand of finishing rolling, i.e., the output speed; S i精卷 : represents the distance between the finishing stand and the pinch roll of the coiler No. i being coiled, i.e., the third distance; T 尾 : represents the distance between the tail of the strip being coiled and the final stand of the finishing mill, i.e., the fourth distance; V 卷 : Indicates the speed of the coiler No. i in production in the figure, that is, the coiling speed.

[0061] S140: Determine whether a difference between the first duration and the second duration satisfies a preset condition, where the preset condition is a time condition determined based on a preparation duration of the second coiler;

[0062] For example, when the difference between the first duration and the second duration meets a preset condition, it can be understood that the difference between the first duration and the second duration is greater than or equal to the preparation time of the second coiler, which is specifically expressed as:

[0063] (S i+1精卷 -H 头 ) / V 精 -(S i精卷 -T尾 ) / V 卷 ≥T 必须 ;

[0064] Among them, T 必须 The preparation time of the second coiler.

[0065] Since the speed may be 0, it is not convenient to use 0 as the denominator, so the condition is transformed into:

[0066] V 卷 (S i+1精卷 -H 头 )-V 精 (S i精卷 -T 尾 )≥T 必须 V 精 V 卷

[0067] When V 卷 (S i+1精卷 -H 头 )-V 精 (S i精卷 -T 尾 )<T 必须 V 精 V 卷 , it is considered that the difference between the first duration and the second duration does not meet the preset condition.

[0068] S150. If the difference between the first time length and the second time length does not meet the preset condition, the target winding speed of the first winder is calculated based on the preset condition, and the first winder is controlled according to the target winding speed.

[0069] By tracking the head and tail of the strip, preparation time is set for the coiler to be put into operation, avoiding production stoppage caused by chasing steel, reducing excessive intervention in the finishing rolling steel feeding, and improving production efficiency and yield rate.

[0070] In a possible implementation, the step of calculating a first time duration for the second strip head to reach the second coiler based on the first distance, the second distance, and the output speed includes:

[0071] Acquiring length data of the second steel strip, and comparing the length data with the first distance;

[0072] If the length data is less than the first distance, obtaining speed change data of the second steel strip after leaving the finishing stand, and calculating a first time duration for the head of the second steel strip to reach the second coiler based on the first distance, the second distance, the speed change data, the length data, and the output speed;

[0073] If the length data is greater than or equal to the first distance, a first time duration for the second strip head to reach the second coiler is calculated based on the first distance, the second distance and the output speed.

[0074] For example, since the strip is slowed down after being produced at a constant speed for a period of time after finishing rolling, when the length data is less than the first distance, there is an error in taking the output speed as the travel speed of the strip. Therefore, the speed change data of the second strip after leaving the finishing last stand is obtained, and the first time it takes for the second strip head to reach the second coiler is calculated based on the first distance, the second distance, the speed change data, the length data and the output speed. That is, the first time it takes for the second strip head to reach the second coiler is obtained more accurately by combining the speed change data of the strip after leaving the finishing last stand, the first distance, the second distance, the length data and the output speed.

[0075] In a possible embodiment, the step of obtaining a first distance between the last finishing stand and the pinch roller of the second coiler, a second distance between the last finishing stand and the head of the second steel strip, a third distance between the last finishing stand and the pinch roller of the first coiler, and a fourth distance between the last finishing stand and the tail of the first steel strip includes:

[0076] Acquiring image data of the area where the finishing rolling stand, the first coiler, and the second coiler are located after the rolling task changes and the second coiler is not put into operation;

[0077] Processing the image data based on image recognition technology to obtain first position information of the finishing stand within the image data, second position information of the pinch roller of the second coiler within the image data, third position information of the head of the second steel strip within the image data, and fourth position information of the tail of the first steel strip within the image data;

[0078] Acquiring setting data of an information acquisition device for capturing the image data;

[0079] The first distance between the last finishing stand and the pinch roller of the second coiler, the second distance between the last finishing stand and the head of the second strip, the third distance between the last finishing stand and the pinch roller of the first coiler, and the fourth distance between the last finishing stand and the tail of the first strip are calculated based on the setting data, the first position information, the second position information, the third position information and the fourth position information.

[0080] For example, through image recognition technology, the first position information, the second position information, the third position information and the fourth position information can be obtained more accurately and quickly without using sensors, reducing hardware and lowering costs.

[0081] In a possible implementation manner, before the step of determining whether the difference between the first duration and the second duration meets a preset condition, the method further includes:

[0082] acquiring initial state information of the second coiler when receiving a target control instruction, wherein the target control instruction is a control instruction for the second steel strip;

[0083] obtaining work requirements for the second steel strip;

[0084] The preparation time of the second coiler for the second steel strip is determined according to the initial state information and the working requirements, and the preset conditions are formulated according to the preparation time.

[0085] Exemplarily, the initial state information can be understood as the distance between the upper pinch roller and the set roller gap. Due to individual differences among winders, when setting preset conditions, the preparation time is determined in combination with the actual state of the winder. For example, when the second winder receives the target control instruction, it is in the shutdown state. The initial state information shows that the distance between the upper pinch roller and the set roller gap is 10 cm. At this time, the time required for the upper pinch roller to press to the set roller gap is long. When the second winder receives the target control instruction, it is in the standby state. The initial state information shows that the distance between the upper pinch roller and the set roller gap is 5 cm. At this time, the time required for the upper pinch roller to press to the set roller gap is short. By obtaining the initial state information of the second winder when receiving the target control instruction, the preset conditions can be formulated more accurately.

[0086] In a possible implementation, the step of controlling the first coiler according to the target coiling speed includes:

[0087] generating an alarm message according to the target winding speed, and sending the alarm message to a preset display device according to a first display rule;

[0088] Obtaining a control instruction for the alarm information, and determining whether a specified speed in the control instruction is consistent with the target winding speed;

[0089] If the designated speed is inconsistent with the target winding speed, determining whether the designated speed is greater than the target winding speed;

[0090] When the designated speed is greater than the target winding speed, controlling the first winding machine based on the designated speed;

[0091] When the designated speed is less than the target winding speed, an error prompt for the control instruction is generated, and the error prompt is sent to the preset display device according to a second display rule.

[0092] Exemplarily, an alarm message is generated based on the target winding speed to provide a reference for technical personnel. That is, when the first winder is controlled according to the target winding speed, a "rear-end collision" will not occur. After considering factors such as subsequent production, the technical personnel will select a specified speed greater than or equal to the target winding speed to control the first winder based on the target winding speed.

[0093] Exemplarily, when the specified speed is less than the target winding speed, an error prompt is generated for the control instruction, and the error prompt is sent to the preset display device according to the second display rule to avoid the impact of incorrect operations of technicians on production.

[0094] Exemplarily, the first display rule may adopt an information display method of screen flashing.

[0095] Exemplarily, the first display rule may adopt an information display method of increasing brightness.

[0096] In a possible implementation, when the designated speed is greater than the target winding speed, the step of controlling the first winder based on the designated speed includes:

[0097] When the designated speed is greater than the target winding speed, comparing the designated speed with a safety threshold;

[0098] If the designated speed is greater than or equal to the safety threshold, a safety warning message is generated and sent to the preset display device according to a third display rule.

[0099] For example, if the coiling speed is too fast, the tail of the strip may have a strong impact on the equipment, leading to a more serious accident. Therefore, the specified speed is limited by a safety threshold to ensure safe production.

[0100] For example, since the production process of strip steel is continuous, if the production speed of the currently produced strip steel is changed, it will affect the overall production process. Therefore, after obtaining the specified speed, the production parameters of other strip steels in the production process (such as the finishing rolling outlet temperature) are reversed based on the specified speed, and combined with the actual production specifications, it is judged whether the reversed production parameters of other strip steels (such as the finishing rolling outlet temperature) meet the safety production requirements. If the reversed production parameters of other strip steels (such as the finishing rolling outlet temperature) do not meet the safety production requirements, in order to ensure control stability, the specified speed needs to be further modified. The modified specified speed can be less than the specified speed before modification, and the modified specified speed is greater than the target coiling speed, which can ensure the stability of control and avoid steel strip tailing.

[0101] On the other hand, Figure 3 As shown, the present application also provides a coiler control system, the system comprising:

[0102] The task monitoring module 201 is used to monitor the rolling task of the hot-rolled strip. When the rolling task changes and the changed rolling task requires the use of different coilers, the hot-rolled strip produced by the rolling task before the change is used as the first strip, the hot-rolled strip produced by the rolling task after the change is used as the second strip, and the coiler corresponding to the first strip is used as the first coiler, and the coiler corresponding to the second strip is used as the second coiler;

[0105] A determination module 204 is configured to determine whether a difference between the first duration and the second duration satisfies a preset condition, wherein the preset condition is a time condition determined based on a preparation duration of the second coiler;

[0106] The control module 205 is used to calculate the target winding speed of the first winder based on the preset conditions if the difference between the first time length and the second time length does not meet the preset conditions, and complete the control of the first winder according to the target winding speed.

[0107] In one possible implementation, Figure 4 As shown, an embodiment of the present application provides a terminal device 300, including: a memory 310, a processor 320, and a computer program 311 stored in the memory 310 and executable on the processor 320. When the processor 320 executes the computer program 311, the terminal device 300 is implemented to: monitor the rolling task of the hot-rolled strip; when the rolling task changes and the changed rolling task requires calling a different coiler, the hot-rolled strip generated by the rolling task before the change is used as the first strip, the hot-rolled strip generated by the rolling task after the change is used as the second strip, the coiler corresponding to the first strip is used as the first coiler, and the coiler corresponding to the second strip is used as the second coiler;

[0109] calculating a first time duration for the head of the second strip to arrive at the second coiler based on the first distance, the second distance, and the output speed, and determining a second time duration for the tail of the first strip to enter the first coiler based on the third distance, the fourth distance, and the coiling speed;

[0110] determining whether a difference between the first time duration and the second time duration satisfies a preset condition, wherein the preset condition is a time condition established based on a preparation time duration of the second coiler;

[0111] If the difference between the first time length and the second time length does not meet the preset condition, the target winding speed of the first winder is calculated based on the preset condition, and the first winder is controlled according to the target winding speed.

[0112] In one possible implementation, Figure 5As shown, an embodiment of the present application provides a computer-readable storage medium 400, on which a computer program 411 is stored. When the computer program 411 is executed by a processor, it is implemented as follows: monitoring the rolling task of a hot-rolled steel strip; when the rolling task changes and the changed rolling task requires calling a different coiler, the hot-rolled steel strip produced by executing the rolling task before the change is used as the first steel strip, the hot-rolled steel strip produced by executing the changed rolling task is used as the second steel strip, and the coiler corresponding to the first steel strip is used as the first coiler, and the coiler corresponding to the second steel strip is used as the second coiler;

[0113] Acquire a first distance between the final finishing stand and the pinch roller of the second coiler, a second distance between the final finishing stand and the head of the second steel strip, a third distance between the final finishing stand and the pinch roller of the first coiler, and a fourth distance between the final finishing stand and the tail of the first steel strip, and acquire an output speed of the final finishing stand and a coiling speed of the first coiler;
