Abstract
Description
Technical Field
[0001] The present invention relates to the field of metallurgical digitalization, and in particular to a slab continuous casting crystallizer arc alignment system and method. Background Art
[0002] Continuous casting machine roll gap detection equipment is a crucial tool for online monitoring of the accuracy of the continuous casting machine's segment rolls, roll alignment, roll opening, and curvature. Roll gap detection is also a crucial step in evaluating billet quality and detecting defects. A critical aspect of the continuous casting process is the alignment of the outer arc rolls—that is, the alignment of the outer arc roll surfaces across the entire width of the continuous casting machine. Excessive roll gap deviation or excessive curvature in the continuous casting machine can disrupt logistics, extend maintenance time, slow production schedules, and compromise product quality.
[0003] Typically, roll gap detection equipment is a standalone device that passes through the continuous casting machine to complete the measurement process. The collected data is stored in a battery-powered computer inside the roll gap detection device. After the measurement is completed, the data is transmitted to a portable computer. The computer processes the measured data using pre-measured calibration data and continuous casting machine parameters and then displays the results. This results in isolated roll gap detection equipment data, which cannot be provided to relevant technicians in a timely manner. Furthermore, the inability to read the data increases the difficulty of subsequent arc data analysis. Summary of the Invention

[0060] The above drawings illustrate specific embodiments of the present invention, which will be described in more detail below. These drawings and the accompanying description are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by reference to specific embodiments. Implementation Method
[0061] The specific embodiments of the present invention are described below to facilitate understanding of the present invention by those skilled in the art. However, it should be clear that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the appended claims, these changes are obvious, and all inventions and creations utilizing the concepts of the present invention are protected.
[0062] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0063] like Figure 1 As shown, the present invention provides a slab continuous casting crystallizer arc alignment system, which includes a roll gap detection module 1, a mobile communication module 2, a data storage module 3, a data analysis module 4 and a data query and display module 5.
[0064] The roll gap detection module 1 is used to detect the roll gap data of the sector in the slab continuous casting crystallizer and transmit the detected roll gap data to the mobile communication module.
[0065] The roll gap detection module 1 can be configured as a roll gap meter, which measures the roll gap data of the continuous casting machine segment through the roll gap meter and imports the roll gap data into the mobile communication module.
[0066] The mobile communication module 2 is used to receive the roll gap data transmitted by the roll gap detection module, and remotely upload the received roll gap data to the data storage module via wireless communication.
[0067] The mobile communication module 2 can be a portable computer, which can receive the roll gap data and upload the roll gap data via the WiFi network. It is worth noting that the mobile communication module 2 can also use other devices with data processing and data transmission to format and transmit the data of the roll gap meter.
[0068] The data storage module 3 is used to collect the roll gap data transmitted by the mobile communication module and store the roll gap data for use by the data analysis module.
[0069] The data storage module 3 can be set as a cloud database to store the roll gap data in the cloud database, so that the staff can view the data remotely, avoiding the occurrence of data islands. It also reduces the size of the front-end equipment and the pressure of data storage, and can better store data.
[0070] The data analysis module 4 is used to call the roll gap data stored in the data storage module and receive the roll gap adjustment amount transmitted by the data query and display module, fit a new roll gap fitting line according to the roll gap adjustment amount, and obtain the adjusted roll gap data according to the new roll gap fitting line; the data analysis module is also used to receive the roll gap data query instruction transmitted by the data query and display module, and transmit the roll gap data and the roll gap fitting line obtained by fitting the roll gap data to the data query and display module according to the roll gap data query instruction, so that the staff can judge which areas need adjustment based on the roll gap fitting line.
[0071] As a digital factory, the data analysis module 4 can not only call the data, but also analyze the data, so that the staff can determine the adjusted roll gap data by adjusting the amount, without having to make multiple adjustments on site, thereby improving work efficiency.
[0072] The data query and display module 5 is used to receive the roll gap adjustment amount and roll gap data query instructions generated by human-computer interaction, and transmit the roll gap adjustment amount and roll gap data query instructions to the data analysis module. After the data analysis module feeds back data, the fedback data is displayed.
[0073] The data query and display module 5 can be a computer, a mobile phone or other data query and display devices, which can realize human-computer interaction and display the data sent by the data analysis module 4, thereby realizing remote viewing of the roll gap data.
[0074] In a possible implementation, the data storage module includes a data acquisition program unit, a message queue unit, and a database.
[0075] The data acquisition program unit is used for acquiring the roll gap data transmitted by the mobile communication module through wireless communication, and transmitting the roll gap data to the message queue unit.
[0076] The message queue unit is used to queue the roll gap data transmitted by the data acquisition program unit one by one, and store the queued roll gap data in the database.
[0077] The database is used to store the roll gap data queued in the message queue unit and provide the stored roll gap data to the data analysis module for calling.
[0078] The slab continuous casting crystallizer arc alignment system provided in this embodiment allows staff to remotely view roll gap data and simulate roll gap adjustment, so that staff can quickly determine the roll gap adjustment amount based on the simulation results, avoiding the problem of multiple on-site debugging and improving the maintenance time of the continuous casting machine. Example
[0079] like Figure 2As shown, the present invention provides an arc alignment method based on an arc alignment system of a slab continuous casting crystallizer, comprising:
[0080] S1. Obtain roll gap data, where the roll gap data includes multiple roll gap point position coordinates.

[0082] S3. Receive a roll gap data query instruction transmitted by the data query display module, call the roll gap data stored in the data storage module according to the roll gap data query instruction, use the roll gap data to fit a roll gap fitting line, and transmit the roll gap data and the roll gap fitting line to the data query display module for display.
[0083] The data query display module shows the roll gap data and the roll gap fitting line to the user, which makes it convenient for the staff to adjust each point on the roll gap.
[0084] S4. When the roll gap data is displayed as a roll gap fitting line through the data query display module, the roll gap adjustment amount generated by human-computer interaction is received in real time, and a new roll gap fitting line is obtained according to the roll gap adjustment amount.
[0085] S5. Based on the new roll gap fitting line, the adjusted roll gap point position coordinates are obtained and transmitted to the data query and display module for display, completing the arc alignment of the slab continuous casting mold. Determining the adjusted roll gap point data based on the adjustment amount allows staff to clearly determine the corresponding adjustment result. If the adjustment result does not meet expectations, the adjustment amount can be modified to find the expected adjustment result. This simulation time is much shorter than the actual on-site operation time, allowing for rapid determination of the final roll gap adjustment amount, improving roll gap adjustment efficiency and resolving the difficulty of roll gap arc alignment in continuous casting machines in the prior art.

[0087] The least squares method is a mathematical optimization technique that finds the best function matching data by minimizing the sum of squared errors. Least squares methods can be used to easily find unknown data and minimize the sum of squared errors between these data and the actual data. Least squares methods can also be used for curve fitting, and other optimization problems can be formulated using least squares methods by minimizing energy or maximizing entropy.
[0088] In a possible implementation, obtaining a new roll gap fitting line according to the roll gap adjustment amount includes:
[0089] Determine the starting point coordinates and the end point coordinates of the roller gap fitting line.

[0091] According to the starting point coordinates, the end point coordinates and the adjustment amount, the first calculation parameter and the second calculation parameter are determined as follows:
[0092] an = ((y1+m)-y2) / (x1-x2)

[0096] a1 = (y1-y2) / (x1-x2)
[0097] b1= y1 - a1 * x1
[0098] The determined first calculation parameter and the second calculation parameter are brought into the function of the new roll gap fitting line to obtain the new roll gap fitting line.
[0099] In a possible implementation, obtaining the adjusted roll gap point position coordinates based on the new roll gap fitting line includes:
[0100] According to the roll gap fitting line and the roll gap data, the longitudinal distance from the roll gap position corresponding to the roll gap data to the roll gap fitting line is determined.
[0101] Based on the longitudinal distance of the roll gap fitting line and the new roll gap fitting line, the adjusted roll gap point position coordinates are obtained.
[0102] In a possible implementation, determining, based on the roll gap fitting line and the roll gap data, a longitudinal distance from a roll gap position corresponding to the roll gap data to the roll gap fitting line includes:
[0103] Obtain the coordinates of the first intersection point (x3, y3) between the roll gap point position coordinates in the roll gap data and the roll gap fitting line in the vertical direction, and determine the coordinates of the first intersection point (x3, y3) based on the roll gap fitting line as follows:
[0104] x3=xp
[0105] y3 = a1 * x3 + b1
[0106] Wherein, a1 represents the third calculation parameter in the roll gap fitting line, b1 represents the fourth calculation parameter in the roll gap fitting line, the roll gap fitting line is, represents the ordinate of the roll gap fitting line, represents the abscissa of the roll gap fitting line, and any coordinate point on the roll gap fitting line is (xp, yp).
[0107] According to any coordinate point (xp, yp) of the roll gap data and the coordinate of the first intersection point (x3, y3), the longitudinal distance from the roll gap position corresponding to the roll gap data to the roll gap fitting line is obtained as follows:
[0108] distance = yp - y3=yp -a1 * x3 - b1
[0109] Wherein, distance represents the longitudinal distance from the roll gap position to the roll gap fitting line.
[0110] In a possible implementation, obtaining the adjusted roll gap point position coordinates based on the longitudinal distance of the roll gap fitting line and the new roll gap fitting line includes:
[0111] Obtain the intersection coordinates (x4, y4) of the roll gap point position coordinates in the roll gap data and the new roll gap fitting line in the vertical direction, and determine the intersection coordinates (x4, y4) based on the roll gap fitting line as follows:
[0112] x4 = xp
[0113] y4 = an * x4 + bn
[0114] According to any coordinate point (xp, yp) of the roll gap data, the coordinates of the intersection point (x4, y4) and the longitudinal distance, the adjusted roll gap point position coordinates are obtained as follows:
[0115] xpn = xp
[0116] ypn= y4 + distance=an * x4 + bn+ distance
[0117] Among them, xpn represents the horizontal coordinate corresponding to the adjusted roll gap point, and ypn represents the vertical coordinate corresponding to the adjusted roll gap point.
[0118] In a possible implementation, the slab continuous casting mold arc alignment method further includes: monitoring the roll gap at different positions using a roll gap detection module to obtain roll gap monitoring data at different positions.
[0119] In a possible implementation, the new coordinates of all the roll gap points are obtained by calculating the new coordinates of the roll gap points through an algorithm, and the data query and display module derives the new coordinates of all the roll gap points.
[0120] According to the new coordinate data of the roll gap point, the auxiliary staff adjusts the crystallizer roll gap parameters.
[0121] The present invention provides a slab continuous casting crystallizer arc alignment method, which solves the problem that the roll gap detection equipment in the prior art is a single device, resulting in data islands and other users being unable to obtain roll gap related information in a timely and direct manner. The method can also analyze the adjusted roll gap data in real time based on the adjustment amount of the roll gap by the staff, thereby solving the problem that the prior art relies on manual analysis based on experience, which makes it difficult to directly understand the results of the adjustment and requires multiple adjustments on site.
[0122] The present invention ensures that the user can conveniently calculate the roll gap adjustment amount by adjusting and analyzing the roll gap, thereby completing the corresponding work as quickly as possible. After the roll gap is quickly adjusted, the maintenance time of the continuous casting machine can be greatly reduced, and the product quality can be improved.
