Technical Field
The invention relates to the technical field of steelmaking continuous casting control, in particular to a casting blank production control method and device.
Background
In the continuous casting production process, the primary blank shell and the copper plate are easy to be bonded, the bonding hot spot can move downwards, and once the primary blank shell and the copper plate reach the lower opening of a continuous casting machine, a steel leakage accident can be caused under the action of the static pressure of molten steel. In order to avoid the occurrence of breakout accidents, once a bonding signal is detected in the production process, the continuous casting machine must be decelerated or stopped to ensure that the torn blank shell is healed.

In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Referring to fig. 1, fig. 1 is a flowchart of a casting blank production control method according to an embodiment of the present application. The casting blank production control method of the present embodiment may be executed by a control device communicatively connected to a basic automation device on the continuous casting process site, and the basic automation device. The control device may include a data processing module, a data communication module, a data storage module, and a production plan optimization module. The data communication module establishes communication with the continuous casting process field basic automation equipment through a switch and an Ethernet to complete data transmission; the data storage module stores data related to the production plan; the data processing module acquires production data from the field PLC and the data storage module to calculate; and the production plan optimizing module acquires the production plan from the data storage module, calculates and acquires an updated production plan by calling the data processing module, and stores the updated production plan in the data storage module. The updated production plan is transmitted to the underlying automation device via the data communication module to execute the updated production plan.
The steps of the cast slab production control method according to the present embodiment will be explained in detail below with reference to fig. 1.
Firstly, S101 is executed, and after the occurrence of bonding in the continuous casting production process is identified, the length of the current uncut casting blank and the original casting blank production parameters are obtained, wherein the original casting blank production parameters comprise the planned cutting length and the cutting length sizing specification range of the previous molten steel uncut casting blank.
Specifically, when the continuous casting production is normally carried out, the casting flow is continuously produced and cut into casting billets according to the original casting billet production parameters, wherein the original casting billet production parameters comprise the planned cutting length and the cut length fixed size range of the uncut casting billet of the previous furnace of molten steel, for example, the planned cutting length is 10m, and the cut length fixed size range is 8.3-11.5m, which means that the planned cutting length of each casting billet is 10m, the shortest length cannot be less than 8.3m, and the most common length cannot exceed 11.5m according to the original casting billet production parameters. Because the positions of the bonding points are random, the cutting is carried out according to the original casting blank production parameters, and the casting blank blocks where the bonding points are located become waste blanks, so that the casting blank materials are wasted.
In addition, because the casting flow is continuously produced and cut into casting blocks according to the original casting production parameters, when the bonding in the continuous casting production process is identified, the length of the current uncut casting block refers to the length from the head of the uncut casting block to the molten steel meniscus in the casting flow, and the control method of the embodiment is to control and execute the cutting of the current uncut casting block after the production parameters of the casting flow to be continuously cut at the next moment are updated. It will be appreciated that the bond point must be located at the end of the currently uncut billet.
Next, S102 is executed, and an optimized length value is obtained based on the length of the currently uncut casting block, the planned cutting length, the position of the bonding point, and the preset length before the bonding point.
The preset length x before the bonding point is the distance from the bonding point to one end of the head of the casting blank, and correspondingly, the preset length y after the subsequent bonding point is the distance from the bonding point to one end of the tail of the casting blank. The preset length before the bonding point and the preset length after the bonding point are set according to the possible spread range of the bonding position on site, different production processes may be different, and the preset lengths need to be set by technicians in the field according to site tests and experience. For example, in the present embodiment, the preset length before the bonding point is 2m, and the preset length after the bonding point is 3 m. Indicating that a distance of 2m and 3m needs to be reserved before and after the bonding position, respectively, when cutting.
It should be noted that the position of the bonding point may be monitored by a basic automation device during the production process when bonding occurs, or may be implemented by installing a camera above the casting flow and acquiring a picture to perform image recognition, which is not limited in this embodiment.
Specifically, the obtaining an optimized length value based on the length of the current uncut casting blank, the planned cutting length, the position of the bonding point, and a preset length before the bonding point specifically includes:
according to the planned cutting length, performing virtual uniform cutting calculation on the current uncut casting blank before bonding to obtain a plurality of virtual casting blank blocks with the size of the planned cutting length and virtual bonding blocks comprising bonding points;
and obtaining the value of the length which can be optimized according to the difference value obtained by subtracting the preset length before the bonding point from the distance between the bonding point on the virtual bonding block and the head of the virtual bonding block.
Specifically, after the original casting blank production parameters are obtained, the original casting blank production parameters are updated according to the positions of the bonding points because the current uncut casting blank is not cut, and the calculation of the length value which can be optimized can be firstly performed according to the virtual cutting, which is actually a process of performing cutting calculation on the current uncut casting blank according to the original casting blank production parameters.
Illustratively, corresponding to the example in S101, the length of the currently uncut casting slab is 56.2m, according to the original casting slab production parameters, the planned cutting length of each casting slab is 10m, the number of blocks for cutting the complete casting slab is 5, the cutting length of the number of blocks for the complete casting slab is 50m, and the remaining length is 6.2m, and bonding occurs at 53.2 m, so that the distance from the bonding point to the head of the virtual bonding block is 3.2m, and since the length of the bonding point is 2m, the optimized length value is 3.2-2 ═ 1.2 m.
It should be noted that, since the value of the optimizable length in this embodiment is a difference between a distance from the virtual bond point on the virtual bond block to the head of the virtual bond block and a preset length before the bond point, except for the above example, when the distance from the head of the virtual bond block is smaller than the preset length before the bond point, the value of the optimizable length is a negative number, which indicates that the cast slab before the bond point has no optimizable length, and the adjustment of the production parameters is not required, which will be explained in detail in S103.
Next, S103 is executed, based on the length of the currently uncut casting blank, the position of the bonding point, the preset length before the bonding point, and the preset length after the bonding point, the optimized length value is distributed to the cutting length of the casting blank block before the bonding point on the basis of the original casting blank production parameter, so as to obtain an updated casting blank production parameter.
The length of a casting blank block in the updated casting blank production parameters is within the cutting length fixed-size specification range, and the preset length y behind the bonding point is the distance extending from the bonding point to one end of the tail of the casting blank;
in a specific implementation process, the length value which can be optimized is distributed into the cutting length of the casting billet block before the bonding point on the basis of the original casting billet production parameters, so that the length before the bonding point meets the minimum preset length before the bonding point, and no redundant casting billet material exists; at this time, the cutting position after the bonding point is optimized according to the preset length after the bonding point and the position of the bonding point. Specifically, the cutting position after the bonding point may be set based on the bonding point position identified in S101, the distance from the cutting position of the cutting machine, and the cumulative length of the cut cast slab.
However, due to the randomness of the positions of the bonding points, the specific positions of the bonding points on the obtained ingot including the bonding points (referred to as bonding points for short) are divided into a plurality of cases according to the original casting production parameters, and how to obtain updated casting production parameters in each of the cases will be described below.
In the first case, if the distance from the bonding point to the head of the virtual bonding block is less than or equal to the preset length before the bonding point, the value of the length which can be optimized is set to be zero, the value of the length which can be optimized is distributed into the cutting length of the casting block before the bonding point on the basis of the original casting block production parameters, and the cutting position after the bonding point is determined according to the preset length after the bonding point and the distance from the bonding point to the tail of the virtual bonding block, so that the updated casting block production parameters are obtained.
This situation has been proposed previously, in which, when the distance between the heads of the virtual blocks is less than the preset length before the bond point, the optimizable length value is negative, which indicates that the slab before the bond point has no optimizable length, no adjustment of the production parameters is necessary, and in which the optimizable length value is set to zero. And regarding the cutting position after the bonding point, directly taking the position with the preset length after the bonding point as the cutting position after the bonding point.
In the second case, if the distance from the bonding point to the head of the virtual bonding block is greater than the preset length before the bonding point, the value of the length which can be optimized is distributed into the cutting length of the casting block before the bonding point on the basis of the original casting block production parameters, and the cutting position behind the bonding point is determined according to the preset length after the bonding point and the distance from the bonding point to the tail of the virtual bonding block, so that updated casting block production parameters are obtained.
Specifically, in the second case, the optimized length is a positive number, and since the bonding points are random, the optimized length value is also variable, so that the length of the block ingot may or may not be within the cut length specification range after the optimized length value is distributed to the cut length of the block ingot before the bonding points. Therefore, the second case is divided into two cases, specifically as follows:
case a: if the optimized length value is distributed to the cutting lengths of the one or more first casting blocks before the bonding point on the basis of the original casting blank production parameters, the distributed cutting lengths of the one or more first casting blocks are within the cutting length fixed size specification range, the optimized length value is distributed to the cutting lengths of the first casting blocks on the basis of the original casting blank production parameters, and the sum of the preset length before the bonding point and the preset length after the bonding point is used as the cutting length of the bonding block, so that the updated casting blank production parameters are obtained.
It should be noted that, since the size of the optimized length value is unknown, it may be divided into a first ingot and the cut length of a divided first ingot is within the cut length specification, and therefore, the optimized length value needs to be divided into the cut lengths of one or more first ingots before the bonding point. The specific allocation mode is that based on the preset length before the bonding point and the length after the bonding point, an optimized length value is allocated to the cutting length of a first cast billet block before the bonding billet, and if the allocated first cast billet block is within the cutting length specified range, the operation is finished; otherwise, the length value which exceeds the cutting length specified range is distributed to the cutting length of the first cast billet block before the billet is bonded in the same step, and the like until the length of the bonding block is within the cutting length specified range.
Illustratively, following the example in S102, the optimized length value is 1.2m, the length of the bonded block is 5m, and 1.2m divides the bonded block into the cutting length (10m) of the first ingot before the bonded billet, so that the divided length of the first ingot is 10+ 1.2-11.2 m, and the process is ended within the cutting length sizing range (8.3-11.5 m). The slab length of the penultimate block before the bonded block is not changed by 10m, and the slab length of the penultimate block is not changed by 10 m.
Case b: if the optimized length value is allocated to the cutting length of the one or more first casting blocks before the bonding point on the basis of the original casting blank production parameters, and the cutting length of the allocated one or more first casting blocks exceeds the cutting length fixed size specification range, on the basis of the original casting blank production parameters, the optimized length value is partially or completely allocated to the cutting length of the casting blocks before the bonding point according to the relation between the optimized length value and the cutting length fixed size specification range, so that the updated casting blank production parameters are obtained.
In the case b, since the cutting length of the one or more first ingot after being distributed exceeds the cutting length specification range, and the specific value exceeding the cutting length specification range affects the distribution processing of the value of the optimized length, the relationship between the value of the optimized length and the cutting length specification range can be optimized, and the value of the optimized length can be partially or completely distributed to the cutting length of the ingot before the bonding point, which can be divided into the following cases:
the following conditions are: if the optimized length value is within the cut length fixed size specification range, on the basis of the original casting blank production parameters, the sum of the preset length before the bonding point and the preset length after the bonding point is used as the cut length of the bonding block, and the casting blank blocks with the size of the optimized length value are added before the bonding block (which is equivalent to the fact that the optimized length value is completely distributed into the cut length of the casting blank blocks before the bonding point), so that updated casting blank production parameters are obtained.
Case two: if the value of the length which can be optimized is larger than the maximum value of the cutting length fixed size specification range, on the basis of the original casting blank production parameters, taking x + y as the cutting length of the bonding block, adding a casting blank block with the size being the maximum value of the cutting length fixed size specification range in front of the bonding block, distributing the rest length to one or more second casting blank blocks in front of the casting blank block, and if the distributed one or more second casting blank blocks are in the cutting length fixed size specification range, completing optimization; otherwise, the residual length is divided into the bonding blocks, and the x + y + residual length is used as the cutting length of the bonding blocks to obtain updated casting blank production parameters.
Case (c): if the value of the length which can be optimized is smaller than the minimum value of the cutting length fixed-length specification range, on the basis of the original casting blank production parameters, taking x + y as the cutting length of the bonding block, and dividing the rest length into one or more first casting blank blocks before the bonding block; otherwise, the residual length is divided into the bonding blocks, and the x + y + residual length is used as the cutting length of the bonding blocks to obtain updated casting blank production parameters.
Next, S104 is executed to control the cutting of the current uncut cast slab into cast slab blocks according to the updated cast slab production parameters.
Specifically, after obtaining the updated casting blank production parameters, the data communication module of the embodiment transmits the updated casting blank production parameters to the basic automation device, so as to execute the updated production plan according to the updated casting blank production parameters. And simultaneously, transmitting the updated casting blank production parameters to a data communication module for storage.
In addition, the control device of this embodiment may also be connected with a terminal device for display, for example, an electronic device such as a PC, a notebook, a mobile phone, a tablet, and a wearable device, and may adopt a queue form to display a production plan and an optimization result in real time.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
in the casting blank production control method of the embodiment, in the continuous casting production process, after the occurrence of bonding in the continuous casting production process is identified, the length of a current uncut casting blank and original casting blank production parameters are obtained, wherein the original casting blank production parameters comprise a planned cutting length and a cutting length fixed-size specification range of the previous molten steel uncut casting blank; obtaining an optimized length value based on the length of the current uncut casting blank, the planned cutting length, the position of the bonding point and a preset length before the bonding point; based on the length of the current uncut casting blank, the position of the bonding point, the preset length before the bonding point and the preset length after the bonding point, the optimized length value is distributed into the cutting length of the casting blank block before the bonding point on the basis of the original casting blank production parameters, and updated casting blank production parameters are obtained; wherein the length of the casting blank block in the updated casting blank production parameters is within the cutting length sizing specification range; and controlling to cut the current uncut casting blank into casting blank blocks according to the updated casting blank production parameters. Because the optimized length of the front part of the casting blank block where the bonding point is located in the original casting blank production parameters is distributed into the cutting length of the casting blank block before the casting blank block where the bonding point is located, the length before the bonding point meets the minimum preset length before the bonding point; meanwhile, according to the preset length behind the bonding point, the cutting position of the rear end of the casting billet where the bonding point is located in the original casting blank production parameters is updated, so that no redundant casting blank exists before and after the casting billet where the bonding point is located. When bonding occurs, the method controls the produced casting blank blocks, can avoid the bonding blocks from occupying the length of redundant casting blanks, and reduces the generation of redundant waste blanks, thereby solving the problem of waste of casting blank materials, and achieving the effects of improving the metal yield and reducing the production cost.
Based on the same inventive concept as the previous embodiment, there is provided in this embodiment a casting block production control apparatus for producing a casting block of a bonding point, referring to fig. 2, the apparatus including:
