[0026] Embodiment one

[0027] Figure 1 A flow chart of a method for verifying a continuous casting casting speed is provided for the first embodiment of the present application. The present embodiment can be applicable to metal casting scenarios, especially liquid metal continuous casting. The method can be executed by a device for verifying a continuous casting casting speed, which can be realized in the form of hardware and / or software, and can be configured in an electronic device. As shown in the figure, the method comprises: Figure 1

[0028] ​S110, determine the length of the continuous casting billet and the casting time length matched with the continuous casting billet.

[0029] The scheme can be executed by a continuous casting control platform, which can be used to manage the continuous casting process of a continuous casting machine. Specifically, the continuous casting control platform can check the continuous casting speed measured based on an encoder at a preset time interval, or can check the continuous casting speed measured based on the encoder in response to an externally triggered check start event.

[0030] The continuous casting control platform can pre-acquire the length of the continuous casting billet and the casting time length matched with the continuous casting billet. The continuous casting billet can be a cooled continuous casting billet, such as a small square billet, and 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 length can be the difference between the cutting times of the two 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 length can be the difference between the cutting start time and the cutting end time of the multiple continuous casting billets. The casting time length of the continuous casting billet can be determined based on the cutting time of the continuous casting billet. Since the same continuous casting flow produces continuous casting billets with the same length, there is usually no error, so the single billet length 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 by a length measuring instrument. Figure 2 A schematic diagram of the length measurement of the continuous casting billet is provided according to an embodiment of the present application, as shown in Figure 2 The continuous casting control platform can be provided with two distance measuring modules, such as laser distance measuring sensors, infrared distance measuring sensors, etc. The two distance measuring modules are respectively used to measure the distance of the two ends of the continuous casting billet. The positions of the two distance measuring modules are known. According to the distance between the first distance measuring 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 distance measuring 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 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 length matched with the continuous casting billet.

[0033] It can be understood that after obtaining the length of the continuous casting billet and the casting time length matched with 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 length matched with the continuous casting billet to obtain the first continuous casting speed.

[0034] S130, determine the check result of the second continuous casting speed according to the first continuous casting speed and the second continuous casting speed pre-acquired; the second continuous casting speed is the continuous casting speed measured based on an encoder deployed on the upper part of the drive roll motor of the continuous casting machine.

[0035] The second continuous casting speed can be calculated based on the motor speed of the driving roller in the continuous casting machine measured by the encoder. The calculation formula of the second continuous casting speed can be represented as: a represents the thermal shrinkage coefficient of the continuous casting billet, n represents the motor speed, D represents the driving roller diameter, and i represents the transmission ratio of the motor and the driving roller. It is easy to understand that the second continuous casting speed is affected by factors such as the setting of the thermal shrinkage coefficient and the change of the driving roller diameter, and may differ from the actual continuous casting speed, so the second continuous casting speed needs to be verified to ensure the accuracy of the continuous casting process.

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

[0037] The technical scheme of the embodiment of the present application determines the length of the continuous casting billet and the casting time matched with the continuous casting billet; determines the first continuous casting speed according to the length of the continuous casting billet and the casting time matched with the continuous casting billet; determines the verification result of the second continuous casting speed according to the first continuous casting speed and the second continuous casting speed obtained in advance; and the second continuous casting speed is the continuous casting speed measured by the encoder deployed on the upper part of the motor of the driving roller in the continuous casting machine. This technical scheme solves the problem of lack of accuracy verification of the continuous casting speed measured by the encoder, and verifies the continuous casting speed measured by the encoder based on the casting time of the continuous casting billet and the length of the continuous casting billet, which is beneficial to test the systematic deviation of the continuous casting machine and ensure the reliability of the continuous casting process.

[0038] Embodiment Two

[0039] Figure 3 A flowchart of a continuous casting speed verification method provided by Embodiment Two of the present application is provided, and the determination process of the length of the continuous casting billet and the casting time is refined based on the above-mentioned embodiments. As shown in Figure 3 the method comprises:

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

[0041] It can be understood that the continuous casting billet output by the continuous casting process should have a specific specification, and therefore the continuous casting control platform can obtain the fixed-length length of the single billet in advance. Based on the single billet length and the casting time length, the first continuous casting speed is calculated, and there is a measurement contingency, which leads to a large error of the first continuous casting speed. In order 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 the preset number of continuous casting billets according to the fixed-length length of the single billet, for example, 3 continuous casting billets. The length of the preset number of continuous casting billets can be the product of the single billet fixed-length length and the preset number.

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

[0043] The continuous casting control platform can obtain the cutting time of the preset number of continuous casting billets and extract the cutting start time and the cutting end time. 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 in 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 in 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 casting time length of the preset number of continuous casting billets according to the cutting start time and the 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 casting time length 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 casting time length 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 casting time length 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 second continuous casting speed obtained in advance; the second continuous casting speed is a continuous casting speed measured based on an encoder deployed on the upper part of a driving roller motor of the continuous casting machine.

[0049] The scheme determines the first continuous casting speed based on the length and the casting time length of the preset number of continuous casting billets, which is beneficial to reduce the time measurement error and ensure the reliability of the first continuous casting speed.

[0050] In one possible scheme, the determination of the verification result of the second continuous casting speed according to the first continuous casting speed and the second continuous casting speed obtained in advance includes:

[0051] According to the difference between the first continuous casting speed and the second continuous casting speed, the verification result of the second continuous casting speed is determined.

[0052] In the scheme, the continuous casting control platform can calculate the difference between the first continuous casting speed and the second continuous casting speed, compare the difference with the preset deviation threshold, if the difference is less than or equal to the preset deviation threshold, the second continuous casting speed is normal, if the difference is greater than the preset deviation threshold, the second continuous casting speed is abnormal. In the case of abnormal second continuous casting speed, the continuous casting control platform can further determine the abnormal reason of the second continuous casting speed.

[0053] The scheme 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 abnormal situation of the second continuous casting speed and timely adjust the continuous casting process.

[0054] In another feasible scheme, the verification result of the second continuous casting speed is determined according to the first continuous casting speed and the second continuous casting speed obtained in advance, comprising:

[0055] According to the ratio of the first continuous casting speed to the second continuous casting speed obtained in advance, the verification result of the second continuous casting speed is determined.

[0056] In the scheme, the continuous casting control platform can calculate the ratio of the first continuous casting speed to the second continuous casting speed, judge whether the ratio is within the preset ratio range, if the ratio is within the preset ratio range, the second continuous casting speed is normal, if the ratio is not within the preset ratio range, the second continuous casting speed is abnormal. In the case of abnormal second continuous casting speed, the continuous casting control platform can further determine the abnormal reason of the second continuous casting speed.

[0057] The scheme 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 abnormal situation of the second continuous casting speed and timely adjust the continuous casting process.

[0058] After determining the verification result change feature, the method further comprises:

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

[0060] The scheme can give an alarm according to the verification result of the second continuous casting speed when the second continuous casting speed is abnormal, for example, through sound, indicator light and display text and other ways, which is beneficial to timely find the abnormality of the continuous casting process, eliminate abnormal factors and ensure the stable operation of the continuous casting equipment.

[0061] In a preferred scheme, the continuous casting machine is a multi-flow continuous casting machine; the continuous casting billet comprises continuous casting billets of each flow;

[0062] The determination of the continuous casting billet length and the matching casting time includes:

[0063] Determine the length of each slab and the matching casting time for each slab;

[0064] The step of determining the first continuous casting speed based on the length of the continuously cast billet and the matching casting time includes:

[0065] The first casting speed for each continuous casting is determined based on the length of each continuous casting billet and the casting time matched for each continuous casting billet.

[0066] The step of determining the verification result of the second continuous casting speed based on the first continuous casting speed and the pre-acquired second continuous casting speed includes:

[0067] Based on the first continuous casting speed matched for each stream and the pre-acquired second continuous casting speed for each stream, the verification result of the second continuous casting speed for each stream is determined.

[0068] Understandably, a continuous casting machine can be a multi-strand continuous casting machine, and the continuously cast billets produced by each strand can be the same or different. The continuous casting control platform can sequentially determine the length of each strand's continuously cast billet and the corresponding casting duration. Based on the length of each strand's continuously cast billet and the corresponding casting duration, it determines the first continuous casting speed for each strand. Then, based on the first continuous casting speed and the pre-acquired second continuous casting speed for each strand, it determines the verification result of the second continuous casting speed for each strand.

[0069] This solution can verify the casting speed of multiple strands on a single continuous casting machine, which helps improve the verification efficiency of casting speed. At the same time, by comparing the verification results of multiple strands casting speed, it is helpful to locate the cause of abnormal casting speed, thereby ensuring the reliability of the continuous casting process.

[0070] Based on the above scheme, 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 speed for each stream, the method further includes:

[0072] Obtain the verification results of the second continuous casting speed for each stream in the continuous casting machine;

[0073] If at least two streams meet the preset conditions, a correction coefficient is determined based on the verification results of the second continuous casting speed of each stream; 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] The continuous casting control platform can obtain the verification result of the second continuous casting speed of each flow of the continuous casting machine after verifying the continuous casting speed of each flow of the continuous casting machine. According to the verification result of the second continuous casting speed of each flow, it is judged whether the multiple flows meet the preset condition. The preset condition includes that the verification results are all abnormal, and the product types are the same.

[0075] It is easy to understand that for the continuous casting machine flow producing the same specification continuous casting billet, if the verification results are all abnormal, it indicates that the abnormal reason of the second continuous casting speed is in the product factor. For example, in the continuous casting production process of the strong cooling steel grade, due to the uneven cooling of the billet, the unstable contact of the billet with the driving roller, etc., the verification continuous casting control platform can adjust the cooling parameters of the continuous casting process.

[0076] The continuous casting control platform can determine a correction coefficient according to the verification result of the second continuous casting speed of each flow to correct the second continuous casting speed. In a feasible scheme, the verification result 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: Wherein, n represents the number of flows with the same product type, k1, k2…kn represent the continuous casting speed ratio of each flow. n Respectively.

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

Computer-readable storage media can include, but are not limited to, electronic, magnetic, optical, electromagnetic, infrared, or semiconductor systems, apparatus, or devices, or any suitable combination of the foregoing. Alternatively, a computer-readable storage medium can be a machine-readable signal medium. More specific examples of a machine-readable storage medium will include one or more lines of a program of instructions in a transitory signal, a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.

[0113] To provide for interaction with a user, the systems and techniques described here can be implemented on an electronic device having a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to the user and a keyboard and a pointing device (e.g., a mouse or a trackball) by which the user can provide input to the electronic device. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user can be received in any form, including acoustic, speech, or tactile input.

[0114] The systems and techniques described herein can be implemented in a computing system that includes a back end component, e.g., as a data server, or that includes a middleware component, e.g., an application server, or that includes a front end component, e.g., a user computer having a graphical user interface or a Web browser through which a user can interact with an implementation of the systems and techniques described herein, or any combination of such back end, middleware, or front end components. The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a local area network (LAN), a wide area network (WAN), a blockchain network, and the Internet.

[0115] The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. A server can be a cloud server, also known as a cloud computing server or cloud host, which is a host product in the cloud computing service system, to solve the defects of large management difficulty and weak business scalability in traditional physical host and VPS service.

[0116] It should be understood that the various forms of flow shown above can be re-ordered, added to, or deleted from without departing from the scope of the present disclosure. For example, the steps recited in the present disclosure can be executed in parallel, executed in sequence, or executed in different orders, as long as the desired results of the technical solutions of the present disclosure can be achieved, and the present disclosure is not limited herein.

[0117] The above detailed description does not constitute a limitation on the protection scope of the present application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
