[0002] Continuous casting is a process of continuously casting liquid metal into billets through a cooling mold. The core of the continuous casting process is to achieve the continuous solidification and forming of liquid metal, and reduce defects such as segregation and shrinkage cavities. The continuous casting drawing speed is the speed at which the billet is drawn out of the mold during continuous casting. The continuous casting drawing speed directly affects the quality of the billet and is a core parameter of the continuous casting process.

[0003] Currently, the continuous casting drawing speed is usually measured by an encoder. A rotary encoder is installed on the motor of the driving roll of the continuous casting machine. By measuring the rotation speed of the driving roll and based on the diameter of the driving roll, the transmission ratio, and the thermal shrinkage coefficient of the billet, the continuous casting drawing speed is calculated. However, the continuous casting drawing speed measured by the encoder is affected by factors such as the setting of the thermal shrinkage coefficient and the wear of the driving roll, which easily leads to a deviation between the measured drawing speed and the actual drawing speed.

[0026] Embodiment 1

[0027] Figure 1 A flowchart of a method for verifying continuous casting drawing speed is provided for Embodiment 1 of the present invention. This embodiment is applicable to the metal casting scenario, especially the continuous casting of liquid metal. This method can be executed by a device for verifying continuous casting drawing speed. The device can be implemented in the form of hardware and / or software, and the device can be configured in an electronic device. As Figure 1 shown, the method includes:

[0028] S110. Determine the length of the continuous casting billet and the casting time corresponding to the continuous casting billet.

[0029] This solution can be executed by the continuous casting control platform, which can be used to manage the continuous casting process of the continuous casting machine. Specifically, the continuous casting control platform can verify the continuous casting speed measured by the encoder at preset time intervals, or can verify the continuous casting speed measured by the encoder in response to an externally triggered verification start event.

[0030] The continuous casting control platform can pre-acquire the length of the continuous casting billet and the casting time of the continuous casting billet. The continuous casting billet can be a cooled continuous casting billet, such as a small square billet. The length of the continuous casting billet can be the length of a single continuous casting billet or the total length of multiple continuous casting billets. If the length of the continuous casting billet is the length of a single continuous casting billet, the casting time can be the difference in cutting times at both ends of the continuous casting billet. If the length of the continuous casting billet is the total length of multiple continuous casting billets, the casting time can be the difference between the cutting start time and the cutting end time of multiple continuous casting billets. The casting time of the continuous casting billet can be determined based on the cutting time of the continuous casting billet. Since the lengths of the continuous casting billets produced by the same continuous casting are the same and there is usually no error, the length of a single billet can be a fixed value.

[0031] To ensure the reliability of the length of the continuous casting billet, the continuous casting control platform can also measure the length of the continuous casting billet through a length measuring instrument. Figure 2 This is a schematic diagram of measuring the length of a continuous casting billet provided in Embodiment 1 of the present invention. As Figure 2 shown, the continuous casting control platform can set two ranging modules, such as laser ranging sensors, infrared ranging sensors, etc. The two ranging modules are respectively used to measure the distances to both ends of the continuous casting billet. The positions of the two ranging modules are known. According to the distance between the first ranging module and the first end of the continuous casting billet, the position of the first end of the continuous casting billet can be determined. According to the distance between the second ranging module and the second end of the continuous casting billet, the position of the second end of the continuous casting billet can be determined. The position of the first end of the continuous casting billet and the position of the second end of the continuous casting billet can be used to determine the length of the continuous casting billet.

[0032] S120. Determine the first continuous casting speed according to the length of the continuous casting billet and the casting time corresponding to the continuous casting billet.

[0033] It can be understood that after obtaining the length of the continuous casting billet and the casting time corresponding to the continuous casting billet, the continuous casting control platform can calculate the ratio of the length of the continuous casting billet to the casting time corresponding to the continuous casting billet to obtain the first continuous casting speed.

[0034] S130. Determine the verification result of the second continuous casting speed according to the first continuous casting speed and the pre-acquired second continuous casting speed; the second continuous casting speed is the continuous casting speed measured based on the encoder deployed on the drive roll motor in the continuous casting machine.

[0035] Among them, the second continuous casting drawing speed can be calculated based on the motor speed of the driving roll in the continuous caster measured by the encoder. The calculation formula of the second continuous casting drawing speed can be expressed as: a represents the thermal shrinkage coefficient of the continuous casting billet, n represents the motor speed, D represents the diameter of the driving roll, and i represents the transmission ratio between the motor and the driving roll. It is easy to understand that the second continuous casting drawing speed is affected by factors such as the setting of the thermal shrinkage coefficient and the change of the driving roll diameter, and there may be a difference from the actual continuous casting drawing speed. Therefore, it is necessary to calibrate the second continuous casting drawing speed to ensure the accuracy of the continuous casting process.

[0036] The continuous casting control platform can use the first continuous casting drawing speed as a reference value, compare it with the second continuous casting drawing speed, determine the difference between the two, and then determine the calibration result of the second continuous casting drawing speed according to the difference between the first continuous casting drawing speed and the second continuous casting drawing speed. Specifically, the continuous casting control platform can determine the calibration result of the second continuous casting drawing speed based on whether the first continuous casting drawing speed is equal to the second continuous casting drawing speed. The continuous casting control platform can also determine the calibration result of the second continuous casting drawing speed according to whether the difference between the first continuous casting drawing speed and the second continuous casting drawing speed is within the first preset range. The continuous casting control platform can also determine the calibration result of the second continuous casting drawing speed according to whether the ratio of the first continuous casting drawing speed to the second continuous casting drawing speed is within the second preset range. The calibration result of the second continuous casting drawing speed can include whether the second continuous casting drawing speed is normal, the difference between the second continuous casting drawing speed and the first continuous casting drawing speed, and the ratio of the second continuous casting drawing speed to the first continuous casting drawing speed, etc.

[0037] The technical solution of the embodiment of the present invention determines the length of the continuous casting billet and the drawing and pouring duration matching the continuous casting billet; determines the first continuous casting drawing speed according to the length of the continuous casting billet and the drawing and pouring duration matching the continuous casting billet; determines the calibration result of the second continuous casting drawing speed according to the first continuous casting drawing speed and the previously obtained second continuous casting drawing speed; the second continuous casting drawing speed is the continuous casting drawing speed measured by the encoder deployed on the driving roll motor of the continuous caster. This technical solution solves the problem that the continuous casting drawing speed measured by the encoder lacks accuracy verification, calibrates the continuous casting drawing speed measured by the encoder based on the drawing and pouring time of the continuous casting billet and the length of the continuous casting billet, which is beneficial to detecting the systematic deviation of the continuous caster and ensuring the reliability of the continuous casting process.

[0038] Embodiment 2

[0039] Figure 3 It is a flowchart of a method for calibrating the continuous casting drawing speed provided by the second embodiment of the present invention. This embodiment is based on the above embodiment and refines the determination process of the length of the continuous casting billet and the drawing and pouring duration. As Figure 3 shown, the method includes:

[0040] S210. Obtain the fixed-length of a single billet, and determine the length of the continuous casting billets of the preset number according to the fixed-length of the single billet.

[0041] It is understandable that the continuous casting billets produced by the continuous casting process should have specific specifications. Therefore, the continuous casting control platform can pre-obtain the specified length of a single continuous casting billet. Calculating the first continuous casting speed based on the length of a single billet and the pouring time is prone to measurement contingency, resulting in a large error in the first continuous casting speed. To reduce the measurement error of the first continuous casting speed and ensure the reliability of the first continuous casting speed, the continuous casting control platform can calculate the length of a preset number of continuous casting billets according to the specified length of a single billet, such as 3 continuous casting billets. The length of the preset number of continuous casting billets can be the product of the specified length of a single billet and the preset number.

[0042] S220. Obtain the cutting start time and cutting end time of a preset number of continuous casting billets.

[0043] The continuous casting control platform can obtain the cutting time of a preset number of continuous casting billets and extract the cutting start time and cutting end time therefrom. It is easy to understand that the cutting start time can be the cutting time of the first end of the first continuous casting billet among the preset number of continuous casting billets, and the cutting end time can be the cutting time of the second end of the last continuous casting billet among the preset number of continuous casting billets. The first end of the continuous casting billet can be the end that is cut first, and the second end of the continuous casting billet is the end that is cut later.

[0044] S230. Determine the pouring time of a preset number of continuous casting billets according to the cutting start time and cutting end time of the preset number of continuous casting billets.

[0045] The difference between the cutting start time and the cutting end time of the preset number of continuous casting billets can be used as the pouring time of the preset number of continuous casting billets.

[0046] S240. Determine the first continuous casting speed according to the length of the preset number of continuous casting billets and the pouring time of the preset number of continuous casting billets.

[0047] The first continuous casting speed can be the ratio of the length of the preset number of continuous casting billets to the pouring time of the preset number of continuous casting billets.

[0048] S250. Determine the verification result of the second continuous casting speed according to the first continuous casting speed and the pre-obtained second continuous casting speed; the second continuous casting speed is the continuous casting speed measured based on the encoder deployed on the driving roll motor in the continuous casting machine.

[0049] This solution determines the first continuous casting speed based on the length and pouring time of a preset number of continuous casting billets, which is beneficial to reducing the time measurement error and ensuring the reliability of the first continuous casting speed.

[0050] In a feasible solution, the determining the verification result of the second continuous casting speed according to the first continuous casting speed and the pre-obtained second continuous casting speed includes:

[0051] Determine the verification result of the second continuous casting speed based on the difference between the first continuous casting speed and the pre-acquired second continuous casting speed.

[0052] In this solution, the continuous casting control platform can calculate the difference between the first continuous casting speed and the second continuous casting speed, compare the difference between the two with the preset deviation threshold. If it is less than or equal to the preset deviation threshold, the second continuous casting speed is normal; if it is greater than the preset deviation threshold, the second continuous casting speed is abnormal. In the case where the second continuous casting speed is abnormal, the continuous casting control platform can further determine the cause of the abnormality of the second continuous casting speed.

[0053] This solution can verify the second continuous casting speed based on the difference between the first continuous casting speed and the second continuous casting speed, which is beneficial to quickly locate the abnormality of the second continuous casting speed and timely adjust the continuous casting process.

[0054] In another feasible solution, the determining the verification result of the second continuous casting speed according to the first continuous casting speed and the pre-acquired second continuous casting speed includes:

[0055] Determine the verification result of the second continuous casting speed according to the ratio of the first continuous casting speed to the pre-acquired second continuous casting speed.

[0056] In this solution, the continuous casting control platform can calculate the ratio of the first continuous casting speed to the second continuous casting speed, and judge whether the ratio of the two is within the preset ratio range. If it is within the preset ratio range, the second continuous casting speed is normal; if it is not within the preset ratio range, the second continuous casting speed is abnormal. In the case where the second continuous casting speed is abnormal, the continuous casting control platform can further determine the cause of the abnormality of the second continuous casting speed.

[0057] This solution can verify the second continuous casting speed based on the ratio of the first continuous casting speed to the second continuous casting speed, which is beneficial to quickly locate the abnormality of the second continuous casting speed and timely adjust the continuous casting process.

[0058] After determining the change characteristics of the verification result, the method further includes:

[0059] If the second continuous casting speed is abnormal, alarm according to the verification result of the second continuous casting speed.

[0060] This solution can alarm according to the verification result of the second continuous casting speed when the second continuous casting speed is abnormal. For example, alarm for abnormalities through means such as sound, indicator lights, and displayed text, which is beneficial to timely detect abnormalities in the continuous casting process, eliminate abnormal factors, and ensure the stable operation of the continuous casting equipment.

[0061] In a preferred solution, the continuous caster is a multi-strand continuous caster; the continuous casting billets include the continuous casting billets produced by each strand;

[0062] Determining the length of the continuous casting billet and the corresponding casting time includes:

[0063] Determining the length of the continuous casting billets for each strand and the corresponding casting time for each strand;

[0064] Determining the first continuous casting speed according to the length of the continuous casting billet and the corresponding casting time includes:

[0065] Determining the first continuous casting speed for each strand according to the length of the continuous casting billets for each strand and the corresponding casting time for each strand;

[0066] Determining the verification result of the second continuous casting speed according to the first continuous casting speed and the pre-acquired second continuous casting speed includes:

[0067] Determining the verification result of the second continuous casting speed for each strand according to the first continuous casting speed for each strand and the pre-acquired second continuous casting speed for each strand.

[0068] It can be understood that the continuous casting machine can be a multi-strand continuous casting machine, and the continuous casting billets produced by each strand of the continuous casting machine can be the same or different. The continuous casting control platform can sequentially determine the length of the continuous casting billets for each strand and the corresponding casting time for each strand, determine the first continuous casting speed for each strand according to the length of the continuous casting billets for each strand and the corresponding casting time for each strand, and then determine the verification result of the second continuous casting speed for each strand according to the first continuous casting speed for each strand and the pre-acquired second continuous casting speed for each strand.

[0069] This solution can realize the verification of the multi-strand continuous casting speeds on one continuous casting machine, which is beneficial to improving the verification efficiency of the continuous casting speed. At the same time, by comparing the verification results of the multi-strand continuous casting speeds, it is beneficial to locate the abnormal reasons for the continuous casting speed, thus ensuring the reliability of the continuous casting process.

[0070] Based on the above solution, the verification result of the second continuous casting speed includes the ratio of the first continuous casting speed to the second continuous casting speed;

[0071] After determining the verification results of the second continuous casting speeds for each strand, the method further includes:

[0072] Obtaining the verification results of the second continuous casting speeds for each strand of the continuous casting machine;

[0073] If there are at least two strands that meet the preset conditions, then determining a correction coefficient according to the verification results of the second continuous casting speeds for each strand; the preset conditions include that the verification results are all abnormal and the product types are the same; the correction coefficient is used to correct the thermal shrinkage coefficient in the calculation formula of the second continuous casting speed.

[0074] After verifying the continuous casting speeds of each strand of the continuous caster, the continuous casting control platform can obtain the verification results of the second continuous casting speeds of each strand of the continuous caster. According to the verification results of the second continuous casting speeds of each strand, it is determined whether there are multiple strands that meet the preset conditions. Among them, the preset conditions include that the verification results are all abnormal and the product types are the same.

[0075] It is easy to understand that for the strands of a continuous caster producing continuous casting billets of the same specifications, if the verification results are all abnormal, it indicates that the abnormal reason for the second continuous casting speed lies in product factors. For example, in the continuous casting production process of a strongly cooled steel type, due to factors such as uneven cooling of the billet and unstable contact between the billet and the driving roller table, it causes the continuous casting control platform to adjust the cooling parameters of the continuous casting process.

[0076] The continuous casting control platform can determine a correction coefficient according to the verification results of the second continuous casting speeds of each strand to correct the second continuous casting speed. In a feasible solution, the verification results of the second continuous casting speed can include the ratio of the first continuous casting speed to the second continuous casting speed, and the correction coefficient can be expressed as: where n represents the number of strands with the same product type, and k1, k2... k n respectively represent the continuous casting speed ratios corresponding to each strand.

[0077] This solution can automatically correct the abnormality of the second continuous casting speed caused by product factors, timely adjust the thermal shrinkage coefficient, and ensure the correctness of the subsequent output of the second continuous casting speed.
