Description

Technical Field

[0001] The present invention belongs to the technical field of steelmaking and continuous casting, and specifically relates to a method, system and equipment for matching continuous casting data and casting billet numbers based on the requirement of slab feedforward precise weighing. Background Art

[0002] In the field of steelmaking and continuous casting, cutting the continuous casting billet to length is an important step, but the standards for cutting the continuous casting billet to length and rolling the steel by weight are not uniform between the processes. This problem affects the steel consumption and rolling yield of steelmaking, and restricts the further reduction of enterprise costs. To solve this problem, it is necessary to develop a slab feedforward accurate weight determination model to achieve accurate cutting of the billet according to the target weight. However, many process and equipment factors have different degrees of influence on the billet weight, and the process and equipment influencing factors are constantly changing with the continuous casting production process. Therefore, it is necessary to accurately correspond the complex and numerous process and equipment data to each continuous casting billet to provide basic data guarantee for model development.

[0003] The current method for matching continuous casting process data with cut ingot numbers mainly adopts an ingot slice tracking method. For example, the related art discloses that: (1) the number of ingot blocks and ingot slices planned to be produced for each stream is determined based on the weight of molten steel and the ingot plan length information; (2) a virtual ingot number and a virtual ingot slice number are generated for each stream; (3) ingot production process parameters and their corresponding impact area position information are determined based on the equipment status at the production site; (4) the casting length of each stream is obtained in real time, and the casting length of the stream is corrected before the first ingot is cut for each stream of each furnace of steel; (5) the position of the ingot slice is determined for each stream based on the casting length; and (6) the ingot production process parameters collected in real time are positioned on each ingot slice according to steps (3) and (5).

[0004] Although the above process can accurately locate the production process parameters on the ingot slices, when the slice data is divided too finely, all the data of each slice needs to be tracked and stored, which requires high system memory and affects the program running speed. When the slice data is divided coarsely, combining the data on the fixed-length ingot will produce large errors. Moreover, when tracking the slices, due to the slight errors in position and time during the tracking process, after a long period of accumulation, it will affect the accuracy of the data correspondence, making it difficult to achieve continuous, complete and accurate data matching. Summary of the invention

[0005] The present invention provides a method for matching continuous casting data with ingot numbers. The method does not require continuous casting data for accurately locating defective parts of ingots as required for ingot quality tracking. It only needs to take fixed-length ingots as the object and determine the continuous casting process data experienced by the entire ingot. The continuous casting data and ingot numbers can be accurately and reliably matched, thereby providing data guarantee for developing a feedforward accurate weight determination model for slabs.

[0009] It should be further explained that, in the method, real-time tracking of continuous casting process data includes: the time when the ladle starts pouring is defined as the starting time when the ladle slide opening signal is received and the weight of the ladle begins to decrease; the time when the tundish starts pouring is defined as the moment when the tundish stopper mechanism changes from closed to open after the first ladle of the casting is started; the cutting start signal and time are defined as the signal and time when a cutting car clamps the synchronization mechanism and falls, and the cutting car and the ingot start to move synchronously; the real-time total casting length based on the ladle weight at preset time intervals.

[0010] It should be further explained that in step S103, when the casting length of the ladle is between the casting lengths of the billet head and the billet tail on the meniscus, the furnace number is determined according to the following method: When the casting length of the ladle during the pouring is ≥ the casting length of the billet head at the meniscus + (the casting length of the billet tail at the meniscus - the casting length of the billet head at the meniscus) / 2, the billet number of this block is matched to the furnace number of the previous furnace of the pouring; When the casting length of the ladle at the start of pouring is < the casting length of the billet head at the meniscus + (the casting length of the billet tail at the meniscus - the casting length of the billet head at the meniscus) / 2, the billet number of this block is matched to the furnace number of the start of pouring.

[0011] It should be further explained that step S103 also includes: based on the distance from the meniscus of the crystallizer to the last pair of clamping rollers of the sector degree, the length of the crystallizer, the length of each sector segment, and the total casting length of the billet head and billet tail when passing through the start and end positions of each section of the continuous casting machine, the real-time data of the fixed weight influencing factors at each collection time point in the preset time range are matched with the corresponding billet number.

[0012] It should be further explained that step S103 also includes: correction of the casting billet number; The distance from the meniscus of the crystallizer to the starting position of cutting is a fixed length in the design of the continuous casting machine; Starting from the cutting of the first ingot, according to the current total casting length, the casting length data of the ingot head and tail when the meniscus of the crystallizer is formed are deduced; The casting length of the head and tail of each ingot when the meniscus is formed is deduced based on the current total casting length for each ingot that starts to be cut; The current time value is queried according to the casting length of the billet head and billet tail on the meniscus, and the billet number being cut is re-matched and saved in the data table. The billet number of the uncut billet is re-matched according to the casting length and the product of the planned fixed length and the shrinkage coefficient.

[0013] It should be further explained that the method also configures the input items of the billet weight determination model; Set the input items of the billet weight model based on the following steps; Based on the time period from when the billet head is formed on the meniscus to when the billet tail is formed on the meniscus, the temperature of the tundish is continuously measured per second, and the average temperature in the time period is obtained as the tundish temperature, and is set as the input item of the billet weight determination model; The casting speed data of the crystallizer section and the casting speed data of the secondary cooling section are set as input items of the billet weight determination model; Based on the mold section, multiple pulling speed data of the billet head of the billet number are obtained from the time when the meniscus is formed to the time when the billet tail exits the lower mouth of the crystallizer, and the average value of the multiple pulling speed data is taken and set as the input item of the billet weight determination model; In the secondary cooling section, multiple pulling speed data from the time when the head of the billet of the current billet number just enters the secondary cooling zone to the time when the tail of the billet exits the last pair of rollers of the fan-shaped section are obtained, and the average value of the multiple pulling speed data is taken and set as the input item of the billet weight determination model; The flow rate of each branch of the crystallizer cooling water, the water volume of each section of the secondary cooling water circuit, the total pressure of the secondary cooling air and the roll gap value at the lower mouth of the last section of the fan shape are set as input items of the billet fixed weight model.

For the purpose of illustration rather than limitation, specific details such as specific system structures and technologies are proposed to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details.

Therefore, the phrases such as "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments" etc. that appear in different places in the present application do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 The figure is a flow chart of a method for matching continuous casting data with a casting billet number in a specific embodiment, the method comprising: S101: Setting and collecting data information during the continuous casting process; the data information includes: continuous casting plan information and setting information, real-time data of factors affecting fixed weight, and real-time tracking data of the continuous casting process.

[0025] In some embodiments, the planning information and setting information include: furnace number, steel type, planned section size, sizing plan, crystallizer number, crystallizer service life, crystallizer lower mouth width and thickness setting value and other information.

[0026] The real-time data of factors affecting fixed weight is based on the study of factors affecting the density of the ingot to determine the real-time data of the process and equipment that need to be collected, including: the temperature of the tundish with continuous temperature measurement, the casting speed of the casting machine, the flow rate of each branch of the crystallizer cooling water, the water volume of each section of the secondary cooling water circuit, the total pressure of the secondary cooling air, and the roll gap value at the bottom of the last section of the fan shape.

[0027] In order to meet the data required for real-time tracking, the real-time tracking data of the continuous casting process include the time when the ladle starts pouring, the weight of the ladle, the time when the intermediate ladle starts pouring, the real-time total casting length, the cutting start signal and time, and the actual set cutting length.

[0028] S102: Based on the preset collection and storage time interval, read the continuous casting plan information and setting information; and continuously detect the tundish temperature, casting machine pulling speed, the flow rate of each branch of the crystallizer cooling water, the water volume of each section of the secondary cooling water circuit, the total pressure of the secondary cooling air, and the roll gap value of the last section of the fan shape; and track the continuous casting process data in real time.

[0029] Optionally, in this embodiment, the data collection and storage time interval is set to 1s, and all data are stored with time as the index.

[0030] For planning information and setting information data, the furnace number, steel type, planned cross-sectional dimensions, and cut-to-length planning data are read in the manufacturing execution system MES (Manufacturing Execution System). The crystallizer number and crystallizer service life are input by the operator through the software interface before pouring. The crystallizer lower mouth width and thickness setting values ​​are read in the first-level interface of the crystallizer width adjustment system.

[0031] In some specific embodiments, when each batch of ladle is poured, the time of pouring, furnace number, steel type, planned cross-sectional dimensions, sizing plan, crystallizer number, crystallizer service life, crystallizer lower mouth width and thickness setting values, and total casting length at this moment are collected and recorded in a data table indexed by time, wherein the time of pouring, furnace number, steel type, crystallizer lower mouth width and thickness setting value data remain unchanged before the next batch of ladle is poured, the planned cross-sectional dimensions and crystallizer number remain unchanged throughout the entire pouring, and the crystallizer life is automatically increased by 1 after each batch of ladle pouring.

[0032] It should be noted that when the first ladle of the casting is started, the molten steel is poured into the tundish at this moment, and there is no casting length in the crystallizer, so the total casting length is 0m. The first casting of the casting records the time when the tundish starts pouring and the time when the continuous casting machine starts speeding up. From the time when the tundish starts pouring to the time when the continuous casting machine starts speeding up, the total casting length is calculated as 0.4m. After that, the total casting length is collected normally in the system.

[0033] The real-time data collection method of the factors affecting the weight determination in this embodiment can collect and store the tundish temperature, casting machine pulling speed, flow rate of each branch of the crystallizer cooling water, water volume of each section of the secondary cooling water circuit, total pressure of the secondary cooling air, and the roller gap value of the last section of the fan shape at a time interval of 1s after the ladle starts pouring. At the same time, the total casting length at this moment is collected and stored, and all data are stored in the database data table with time as the index.

[0034] In order to meet the data required for real-time tracking, the pouring start time of the large ladle is defined as the starting moment when the ladle slide opening signal is received and the weight of the large ladle decreases; the pouring start time of the tundish is defined as the moment when the tundish stopper mechanism changes from closed to open after the first ladle of the casting is started; the cutting start signal and time are defined as the signal and time when the cutting car clamps the synchronization mechanism and starts to move synchronously with the ingot; the large ladle weight and the real-time total casting length are collected in the system at 1s time intervals; the actual set length of the cutting is collected in the sizing system when the start cutting signal occurs, and all data are stored in the database data table with time as the index.

[0035] S103: When the first furnace of the continuous casting machine starts casting, and after each ingot is cast, a ingot number is generated according to the total casting length and the product of the planned length and the shrinkage coefficient, and the ingot number is assigned to the tail of the cast ingot.

[0036] The pre-generation process of the ingot number in this embodiment is to set the length of the first ingot according to the process after the first furnace of the continuous casting machine starts pouring, and assign the ingot number after the casting is completed, that is, when the tail of this ingot is formed on the meniscus.

[0037] The ingot number of this embodiment is composed of the furnace number and the sequence number, and the ingot number is "furnace number + 0"; based on the total casting length direction, according to the planned fixed length * shrinkage coefficient (such as 1.018), the ingot number is assigned after the tail of each ingot is cast (that is, when the tail of this ingot is formed on the meniscus).

[0038] It should be noted that when the casting length of the ladle is between the casting lengths of the billet head and the billet tail on the meniscus, this billet casting involves two furnace numbers, and the furnace number can be determined according to the following method: When the casting length of the ladle during pouring is ≥ the casting length of the billet head at the meniscus + (the casting length of the billet tail at the meniscus - the casting length of the billet head at the meniscus) / 2, the billet number of this block is matched to the furnace number of the previous furnace during the pouring.

[0039] When the casting length of the ladle at the start of pouring is < the casting length of the billet head at the meniscus + (the casting length of the billet tail at the meniscus - the casting length of the billet head at the meniscus) / 2, the billet number of this block is matched to the furnace number of the start of pouring.

[0040] S104: After the billet number is generated, all data in the planning information and setting information are matched with the billet number according to the casting length of the billet head and billet tail on the meniscus in combination with the preset data table.

[0041] The pre-matching method of the ingot number in this embodiment may include: after the ingot number is generated, querying the data table according to the casting length of the ingot head and the ingot tail on the meniscus to match all the data in the planning information and the setting information with the ingot number.

[0042] The distance from the meniscus of the crystallizer to the last pair of clamping rollers of the sector degree is a fixed value, and the length of the crystallizer and the length of each sector segment are fixed values, which can correspond to the total casting length of the billet head and billet tail when they pass through the start and end positions of each section of the continuous casting machine. The corresponding time range can be queried according to the data table collected and stored at intervals of 1s, and the real-time data of the factors affecting the fixed weight every 1s in this time range can be matched with the corresponding billet number.

[0043] Furthermore, as a refinement and extension of the specific implementation of the above embodiment, the billet number is also corrected after the billet number is matched. The specific implementation process of the billet number correction includes the following methods.

[0044] In view of the fact that the length of a single billet is calculated by the planned length * contraction coefficient as the length of each billet, it is to meet the requirement of predicting the billet weight before cutting, and thus determine the actual billet cutting length according to the parameters of various process equipment. However, the actual billet cutting size cannot completely meet the length of the planned length * contraction coefficient, so the billet number needs to be corrected when the billet is cut.

[0045] For this embodiment, the distance from the meniscus of the crystallizer to the starting position of cutting is a fixed length in the design of the continuous casting machine. Therefore, when the first ingot is cut, the casting length data of the ingot head (the casting length of the first ingot head is 0m when the meniscus of the crystallizer is formed) and the ingot tail when the meniscus of the crystallizer is formed can be inferred according to the current total casting length. Thereafter, the casting lengths of the ingot head and tail when the meniscus is formed can be inferred for each ingot according to the current total casting length.

[0046] The current time value is queried according to the casting length of the billet head and billet tail on the meniscus, and the billet number being cut is re-matched in combination with the preset time range and saved in the data table. The billet number of the uncut billet is re-matched according to the casting length and "planned length * shrinkage coefficient" with this correction.

[0047] After the above modification process, the casting length of the billet head and billet tail of each billet when the meniscus of the crystallizer is formed can be calculated according to the total casting length, and the billet number being cut can be re-matched in combination with the preset time range, which can improve the accuracy of the correspondence between the continuous casting data and the actual billet. In addition, in the continuous casting production process, each billet needs to have a unique billet number to distinguish and track. Through the billet number correction process, it can be ensured that each billet has an accurate and unique billet number.

[0048] In an embodiment of the present invention, based on step S103, an example of a method for processing, calculating and applying data is given below, and its specific implementation scheme is described in a non-limiting manner.

[0049] In this embodiment, the continuous casting process data is matched with the ingot number to meet the demand for accurate weighing of the slab. Since the amount of data generated by each ingot casting process is large, the data needs to be processed and calculated to make it an input item of the ingot weighing model.

[0050] In this embodiment, the planning information and setting information data all change according to the furnace. After matching all the data in the planning information and setting information with the billet number, the planning information and setting information data and the billet number are uploaded to the billet weight determination model.

[0051] It should be noted that the real-time data of the factors affecting the fixed weight corresponding to each ingot number are collected at intervals of 1 second. The corresponding data volume is large. In order to meet the requirements of the fixed weight model, the data needs to be processed. The processing, calculation and application of each data involve the following forms.

[0052] For the continuously measured tundish temperature, the tundish temperature is only related to the current ingot. Therefore, the tundish temperature uses the average value of all continuously measured tundish temperatures collected in seconds from the time when the ingot head corresponding to the ingot number is formed on the meniscus to the time when the ingot tail is formed on the meniscus as an input item of the fixed weight model.

[0053] As for the casting speed of the casting machine, due to the continuity of the ingot, the pulling speed of the entire process from the formation of the meniscus shell to the beginning of the ingot cutting has an important influence on other process parameters (such as light pressure execution data, cooling water volume, etc.), which is the key data affecting the ingot weight.

[0054] Since the cooling and process equipment in each section are obviously different, the degree of influence on the fixed weight is also different. The processing and calculation of the casting speed data are divided into two sections, including the crystallizer section and the secondary cooling section. The two casting speed data are used as input items of the fixed weight model.

[0055] In the crystallizer section, the pulling speed data of the time period from the formation of the billet head at the meniscus to the billet tail exiting the lower mouth of the crystallizer are taken, and the average of the pulling speed data is taken as the pulling speed data of the fixed weight model.

[0056] In the secondary cooling section, the pulling speed data from the time when the head of the billet of this billet number just enters the secondary cooling zone to the time when the tail of the billet leaves the last pair of rollers of the fan-shaped section are taken, and the average of these pulling speed data is taken as the pulling speed data of the fixed weight model.

[0057] For the flow rate of each branch of the crystallizer cooling water, we can take the unit time flow rate data of each branch of the crystallizer cooling water from the time when the head of the billet of this billet number is formed on the meniscus to the time when the tail of the billet exits the lower mouth of the crystallizer, take the average of the unit flow rate data of each branch, and multiply it by the time of the entire billet casting to get the flow rate data of each branch of this billet, which is used as the input item of the fixed weight model.

[0058] The water volume configuration method of each section of the secondary cooling water circuit of the present embodiment can be to obtain the secondary cooling water volume data per unit time in the time range from when the head of the billet of the current billet number just enters a certain secondary cooling zone to when the tail of the billet leaves this secondary cooling zone, take the average of these data, and multiply this average by the time the entire billet has passed to obtain the water volume data of this billet passing through this secondary cooling zone, calculate the flow data of the billet passing through each secondary cooling zone, summarize and sum it up as the sum of the secondary cooling water volumes experienced by this billet, divide the sum of the secondary cooling water volumes of this billet by the planned fixed length of this billet to obtain the total secondary cooling water volume value per unit length, and use this data as an input item of the fixed weight model.

[0059] The total pressure of the secondary cooling air is used as an input item of the fixed weight model. The total pressure data of the secondary cooling air in the time range from when the head of the billet of this billet number just enters the secondary cooling zone to when the tail of the billet leaves the last pair of rollers of the fan-shaped section can be taken, and the average value of these data can be taken as an input item of the fixed weight model.

[0060] In this embodiment, the roll gap value at the bottom of the last section of the sector degree can be considered to be only relevant to this piece of ingot. The roll gap value at the bottom of the last section of the sector degree adopts the average value of all roll gap values ​​at the bottom of the last section of the sector degree collected in seconds corresponding to the ingot number as an input item of the fixed weight model.

[0061] As a preferred method for matching continuous casting data with ingot numbers in this embodiment, another specific implementation of this method will be described in detail below.

[0062] Set and collect data information during the continuous casting process. Data information includes continuous casting plan information and setting information, such as furnace number, steel type, planned cross-section size, fixed-length plan and other data information, which are all pre-set parameters before continuous casting production. At the same time, collect real-time data of factors affecting fixed weight, which can reflect various state changes in the continuous casting process in real time, including tundish temperature, casting machine pulling speed, and flow rate of each branch of crystallizer cooling water. It can also record real-time tracking data of the continuous casting process, specifically, it can record key events and time points in the continuous casting process, such as the time when the large ladle starts pouring, the time when the medium ladle starts pouring, etc.

[0063] When collecting these data, the collection and storage time interval is preset. This can ensure the real-time nature of the data and avoid data redundancy and loss. At the same time, part of the continuous casting plan information and setting information is read in the manufacturing execution system, and the operator configures other relevant information based on the operation interface.

[0064] Next, when the first furnace of the continuous casting machine starts pouring and the ingot casting is completed, the ingot number is generated based on the total casting length and the product of the planned length and the shrinkage coefficient. The ingot number is unique and can represent all the information and data of this ingot. Then, the ingot number is assigned to the end of the cast ingot.

[0065] In order to match the collected data with the billet number, the casting length of the billet head and billet tail on the meniscus is combined with the preset data table. The preset data table is formulated based on the design of the continuous casting machine and actual production experience, and can accurately match the data corresponding to each billet.

[0066] In the implementation process, when the casting length of the ladle is between the casting length of the billet head and the billet tail on the meniscus, the furnace number of the billet is determined according to certain rules. The rules are based on the physical phenomena and production experience in the continuous casting process, which can ensure that the source of each billet can be accurately traced.

[0067] In order to further improve the accuracy and traceability of the data, the ingot number will be corrected. The correction process is based on the actual operation of the continuous casting machine and production data, which can ensure that the ingot number corresponds to the actual ingot produced.

[0068] It can be seen that the method for matching continuous casting data with ingot numbers of the present invention collects various data information during the continuous casting process and matches the information with the ingot number according to certain rules and data tables. This method can improve the automation level and management efficiency of continuous casting production.

[0069] The implementation process of this method is described below with a specific embodiment. Take a steel plant's one-machine-one-stream slab continuous casting machine that can produce slabs with thicknesses of 200mm, 250mm, 300mm and widths of 1800-2450mm as an example. The continuous casting machine uses a combined crystallizer, the length of the crystallizer copper plate is 900mm, the lower mouth of the crystallizer has a foot roller section, and below the foot roller section are curved section 0, arc sections 1-6, straightening sections 7-8, and horizontal sections 9-14. There is no spray water cooling after section 14 until the first cutting point. The flame cutting machine cuts the cast into fixed-length billets and then cuts them again after the second cutting before entering the next process. The distance from the meniscus of the crystallizer to the last pair of clamping rollers in section 14 is 34.2m, and the distance from the meniscus of the crystallizer to the first cutting point is 41.65m.

[0070] S201: Basic data collected, including: ① Planning information and setting information data: furnace number, steel type, planned section size, cut-to-length plan, mold number, mold service life, mold lower opening width and thickness setting value, etc.; ② Real-time data of factors affecting weight determination: By studying the factors affecting the density of the ingot, the real-time data of the process and equipment that need to be collected are determined, including: the temperature of the tundish with continuous temperature measurement, the casting speed of the casting machine, the flow rate of each branch of the cooling water of the crystallizer, the water volume of the cooling water circuit of each section, the total pressure of the secondary cooling gas, and the roll gap value of the last section of the fan shape; ③ To meet the data required for real-time tracking: the time when the large ladle starts pouring, the weight of the large ladle, the time when the tundish starts pouring, the real-time total casting length, the cutting start signal and time, and the actual set length of a cut.

[0071] The above data come from different primary, secondary, and tertiary systems or need to be manually input. Interfaces are established with these systems to enable data collection at a minimum time interval of 1 second.

[0072] S202: Define data collection and storage rules.

[0073] When each batch of ladle is poured, the time of pouring, furnace number, steel type, planned cross-sectional dimensions, length plan, mold number, mold service life, mold lower opening width and thickness setting value, and total casting length at this moment are collected and recorded in a data table indexed by time. The time of pouring is the furnace number of the pouring furnace. The time of pouring, furnace number, steel type, mold lower opening width and thickness setting value data remain unchanged before the next batch of ladle is poured. The planned cross-sectional dimensions and mold number remain unchanged throughout the entire pouring. The mold life is automatically increased by 1 after each batch of ladle pouring.

[0074] It should be noted that when the first ladle of the casting furnace is started, the molten steel is poured into the tundish at this moment, and there is no casting length in the crystallizer, and the total casting length is 0m. The first furnace of the casting furnace records the time when the tundish starts pouring and the time when the continuous casting machine starts speeding up. From the time when the tundish starts pouring to the time when the continuous casting machine starts speeding up, the speeding up is started after the molten steel is cast to a length of 0.4m in the crystallizer. During this period, the total casting length is calculated as 0.4m. After that, the total casting length is normally collected in the system.

[0075] Configure real-time data of factors affecting fixed weight. Specifically, the continuously measured tundish temperature, casting machine pulling speed, flow rate of each branch of crystallizer cooling water, water volume of each section of secondary cooling water circuit, total pressure of secondary cooling air, and roller gap value at the bottom of the last section of fan shape are all collected and stored at intervals of 1s after the ladle starts pouring. At the same time, the total casting length at this moment is collected and stored. All data are stored in the database data table with time as the index.

[0076] In this example, to meet the data required for real-time tracking: the time when the ladle starts pouring is defined as the starting moment when the ladle slide opening signal is received and the ladle weight begins to decrease; the time when the tundish starts pouring is defined as the moment when the tundish stopper mechanism changes from closed to open after the first ladle of the casting is started; the cutting start signal and time are defined as the signal and time when the cutting car clamps the synchronization mechanism and starts to move synchronously with the ingot; the ladle weight and the real-time total casting length are collected in the system at 1s time intervals; the actual set length for cutting is collected in the sizing system when the start cutting signal occurs, and all data are stored in the database data table with time as the index.

[0077] S203: Generation and matching of ingot numbers.

[0078] As for the pre-generation method of the ingot number, after the first furnace of the continuous casting machine starts pouring, the length of the first ingot to be poured is the process setting (such as 0.8m). After the casting of the 0.8m ingot is completed (that is, when the tail of this ingot is formed on the meniscus), the ingot number is assigned. The ingot number is composed of the furnace number and the sequence number. The number of this ingot is "furnace number + 0"; thereafter, according to the planned fixed length * shrinkage coefficient (1.018) on the total casting length, after the tail of each ingot is cast (that is, when the tail of this ingot is formed on the meniscus), the ingot number is assigned.

[0079] It should be noted that when the casting length of the ladle is between the casting length of the billet head and the billet tail on the meniscus, that is, this billet casting involves two furnace numbers, the furnace number can be determined according to the following method: When the casting length when the ladle starts pouring ≥ the casting length of the billet head at the meniscus + (the casting length of the billet tail at the meniscus - the casting length of the billet head at the meniscus) / 2, the billet number of this block is matched to the furnace number of the previous furnace in the pouring furnace; when the casting length when the ladle starts pouring < the casting length of the billet head at the meniscus + (the casting length of the billet tail at the meniscus - the casting length of the billet head at the meniscus) / 2, the billet number of this block is matched to the furnace number of the pouring furnace.

[0080] For example: if the first to fifth ingots (excluding the head ingot) are cast in the current pouring, the first head ingot is 0.8m long, the first two ingots are planned to be 7m long, and the last three ingots are planned to be 8.5m long, then the casting length of the tail of the tenth ingot when the meniscus is formed is: 0.8+7*1.018*2+8.5*1.018*3=41.011m, and the head of the fifth ingot is at the meniscus The casting length during formation is: 41.011-8.5*1.018=31.831m. According to the above formula, 31.831+(41.011-31.831) / 2=36.421m. At this time, the casting length of the ladle is 37.2m, which is greater than 36.421m. The number of this ingot needs to match the furnace number of the previous furnace that is being poured at this time, that is, the furnace number of the first furnace in the pouring.

[0081] Pre-match the ingot number. After the ingot number is generated, all the data in the planning information and setting information can be matched with the ingot number according to its matching furnace number and ladle pouring time.

[0082] The distance from the meniscus of the crystallizer to the last pair of clamping rollers of the sector is a fixed value, and the length of the crystallizer and the length of each sector segment are fixed values, which can correspond to the total casting length of the billet head and billet tail when they pass through the start and end positions of each section of the continuous casting machine. The corresponding time range can be queried according to the data table that collects and stores data at time intervals of 1s, and the number collected every 1s in this time range is matched with the corresponding billet number.

[0083] Correct the billet number. Combined with the above single billet length, the planned length * shrinkage coefficient can be used as the fixed length of each billet. This is to meet the prediction of the billet weight before cutting and determine the actual cutting length of the billet according to the parameters of various process equipment. The actual cutting billet size cannot completely meet the length of "planned length * shrinkage coefficient", so the billet number needs to be corrected when the billet is cut.

[0084] The distance from the meniscus of the crystallizer to the starting position of cutting is a fixed length in the design of the continuous casting machine. Therefore, when the first ingot is cut, the casting length data of the ingot head (the casting length of the first ingot head when the meniscus of the crystallizer is formed is 0m) and the ingot tail when the meniscus of the crystallizer is formed can be deduced according to the current total casting length. After that, the casting length of each ingot head and tail when the meniscus is formed can be deduced according to the current total casting length for each ingot that starts cutting at a cutting position. The current time value is queried based on the casting length of the billet head and billet tail on the meniscus, and the billet number being cut is re-matched and saved in the data table based on this time range. The billet number of the uncut billet is re-matched according to the casting length and "planned length * shrinkage coefficient" with this correction.

[0085] For example, the distance from the meniscus of the crystallizer to the starting point of a cutting is 41.65m. If the first furnace head billet of the casting is currently cut, the total casting length is 42.483m, the time is 13:15:30, the casting length of the head of the head billet when the meniscus is formed is 0, the time is 12:35:00 when the tundish starts pouring, and the casting length of the tail billet when the meniscus is formed is 42.483-41.65=0.833m. The time when the total casting length is 0.833m is 12:37:15 when it is queried in the data table. According to the time range when the billet head and billet tail are formed at the meniscus, all The data is matched to the first billet casting number, replacing the original matching billet number range. The original first billet casting number matching range based on "planned length * shrinkage coefficient" should be 0m to 0.8*1.018=0.8144m of total casting length and the corresponding time range. It is currently corrected to the range from 0m to 0.833m of total casting length and the corresponding time range. At the same time, the billet numbers of uncut billets are re-matched according to the casting length and "planned length * shrinkage coefficient" with this correction, that is, the billet numbers are re-assigned after the casting length of 0.833m and the time of 12:37:15.

[0086] When the tail of the second ingot is cut, the casting length is 49.56m, the time is 13:23:06, the casting length of the head of this ingot when the meniscus is formed (that is, the casting length and time of the head and tail of the previous ingot) is 0.833m, the time is 12:37:15, the total casting length of the tail when the meniscus is formed is: 49.56-41.65=7.91m, the query time is 12:45:50, according to the time range when the second ingot head and tail are formed at the meniscus, all data are matched to the second ingot number, replacing the original matching ingot number range, and at the same time, the ingot number of the uncut ingot is re-matched according to the casting length and "planned length * shrinkage coefficient" with this correction.

[0087] S204: Processing, calculation and application of data.

[0088] In this example, the continuous casting process data is matched with the ingot number to meet the demand for accurate slab weight determination. Since the amount of data involved in each ingot is large, the data needs to be processed and calculated to become the input item of the ingot weight determination model.

[0089] The planning information and setting information data are changed according to the furnace, and are matched with the billet number according to the method described in step S203, and these data are uploaded to the billet weight determination model.

[0090] The real-time data of the weight-fixing influencing factors corresponding to each billet number are collected at intervals of 1 second. The corresponding data volume is large. In order to meet the requirements of the weight-fixing model, the data needs to be processed. The processing, calculation and application methods of each data are as follows: a. Continuously measured tundish temperature: The tundish temperature is only related to the current ingot. Therefore, the tundish temperature uses the average value of all continuously measured tundish temperatures collected in seconds from the time when the ingot head corresponding to the ingot number is formed on the meniscus to the time when the ingot tail is formed on the meniscus as an input item of the fixed weight model.

[0091] b. Casting machine drawing speed: Due to the continuity of the billet, the drawing speed of the entire process from the formation of the meniscus billet shell to the beginning of the billet cutting has an important impact on other process parameters (such as light pressure execution data, cooling water volume, etc.), which is the key data affecting the billet weight. Due to the obvious differences in cooling and process equipment in each section, the degree of influence on the weight is also different. The processing and calculation of the drawing speed data are divided into two sections, including the crystallizer section and the secondary cooling section. The two drawing speed data are used as input items of the weight determination model.

[0092] In the crystallizer section, the pulling speed data of the time period from the formation of the billet head at the meniscus to the billet tail exiting the lower mouth of the crystallizer are taken, and the average of these pulling speed data is taken as the pulling speed data 1 of the fixed weight model; In the secondary cooling section, the pulling speed data of the time range from when the head of the billet of this billet number just enters the secondary cooling zone to when the tail of the billet leaves the last pair of rollers of the fan-shaped section are taken, and the average of these pulling speed data is taken as the pulling speed data 2 of the fixed weight model; c. Flow rate of each branch of cooling water for the crystallizer: Take the unit time flow rate data of each branch of cooling water for the crystallizer from the time when the billet head of the billet is formed on the meniscus to the time when the billet tail exits the lower port of the crystallizer, take the average value of the unit flow rate data of each branch, and multiply it by the time of the entire billet casting to get the flow rate data of each branch of the billet, which is used as the input item of the fixed weight model; d. Water volume of each section of the secondary cooling water circuit: take the secondary cooling water volume data per unit time from the time when the head of the billet of this billet number just enters a certain secondary cooling zone to the time when the tail of the billet leaves this secondary cooling zone, take the average of these data, and multiply this average by the time the entire billet has passed to obtain the water volume data of this billet passing through this secondary cooling zone, calculate the flow data of the billet passing through each secondary cooling zone, and summarize the sum to get the sum of the secondary cooling water volume experienced by this billet, divide the sum of the secondary cooling water volume of this billet by the planned fixed length of this billet to get the total secondary cooling water volume per unit length, and use this data as an input item of the fixed weight model.

[0093] For example, in this example, the continuous casting machine has 10 secondary cooling zones, and the "planned fixed length * shrinkage coefficient" of the billet to be calculated is 8.25m. The average value of the secondary cooling water volume per unit time, the passing time, the total water volume when passing through a single zone, the total water volume, and the total secondary cooling water volume per unit length when the billet passes through each secondary cooling zone are calculated as follows: Table 1 Calculation of secondary cooling water volume

[0094] In this example, the total amount of water experienced by the billet per unit length (1140 L / m) calculated last in the table is used as an input item for the fixed weight model.

[0095] e. Total pressure of secondary cooling air: Take the average value of the total pressure of secondary cooling air in the time range from when the head of the ingot of this ingot number just enters the secondary cooling zone to when the tail of the ingot leaves the last pair of rollers of the fan-shaped section as an input item of the fixed weight model.

[0096] f. Roll gap value at the last section of the sector degree: It is only relevant to the current ingot, so the roll gap value at the last section of the sector degree adopts the average value of all roll gap values ​​at the last section of the sector degree collected by seconds corresponding to the ingot number as an input item of the fixed weight model.
