[0033] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0034] In order to solve the problem of lack of a more convenient and intelligent method for measuring the stiffness of a rolling mill, an embodiment of the present invention provides a method for measuring the stiffness of a rolling mill, such as Figure 1 As shown, the method includes:

[0035] S101, when the rolling mill is being calibrated, detecting the extension amount and rolling force of the hydraulic cylinder of the rolling mill in real time;

[0036] For example, by networking with the rolling mill control system, during the execution of the rolling mill calibration process, the actual value of the hydraulic cylinder extension amount and the actual value of the rolling force during the rolling mill calibration process are automatically collected.

[0037] For example, this solution collects data in real time, connects to the rolling mill control system, and uses the OPC interface of the rolling mill control system screen software to edit and package the actual value of the hydraulic cylinder extension and the actual value of the rolling force. Through Ethernet, socket communication is used to realize data collection of the editing points.

[0038] Exemplarily, this solution implements point editing and packaging, groups the hydraulic cylinders and rolling force data on each side of each rolling mill, and obtains two groups of data for one rolling mill, which are packaged into one data packet according to encryption rules.

[0039] S102. Determine the rolling mill stiffness based on the hydraulic cylinder extension amount and the rolling force.

[0040] For example, calculating mill stiffness by networked data collection of hydraulic cylinder extension and rolling force eliminates the need for independent stiffness measurements, increases the frequency of stiffness testing, significantly shortens the rolling gap, and improves steelmaking production efficiency. Dynamic monitoring of stiffness data is also possible, facilitating the identification of mill degradation trends and enabling preventive maintenance. Calculating mill stiffness based on hydraulic cylinder extension and rolling force is an existing method and will not be discussed here.

[0041] By utilizing the above-mentioned technical solution, the present invention provides a method for measuring rolling mill stiffness. This method addresses the lack of a more convenient and intelligent method for measuring rolling mill stiffness. The present invention detects the hydraulic cylinder extension and rolling force of the rolling mill in real time while the mill is being calibrated; the rolling mill stiffness is determined based on the hydraulic cylinder extension and rolling force. In this scheme, by utilizing the post-roller-changing calibration process of the rolling mill to calculate the rolling mill stiffness through networked data collection of hydraulic cylinder extension and rolling force, the process of independent stiffness measurement is eliminated, the number of stiffness tests is increased, the rolling gap is greatly shortened, and the production efficiency of steel rolling is improved. Dynamic monitoring of stiffness data is also achieved, making it easier to understand the deterioration trend of the rolling mill and perform preventive maintenance.

[0042] In one embodiment, the real-time detection of the extension amount and rolling force of the hydraulic cylinder of the rolling mill includes:

[0043] When it is detected that the rolling force is greater than or equal to 10 kN, the recording of the extension amount of the hydraulic cylinder and the rolling force is started.

[0044] For example, during the mill calibration process, this solution triggers data collection when the rolling force exceeds 10 kN and stops when the rolling force falls below 10 kN. This solution also filters the data, parsing the acquired data packets and removing data with missing values, empty values, or out-of-range data.

[0045] In one embodiment, the method further includes:

[0046] The above rolling mill stiffness is stored in a cloud server and sent to a mobile terminal associated with the user.

[0047] Exemplarily, the data processing and stiffness calculation program is deployed in a cloud server, which is used to screen and filter the data obtained by the data collection method, and obtain the stiffness value according to the stiffness calculation formula of the valid data. The stiffness calculation method is to use a high-level language to write a program to implement the calculation formula of the bounce equation and cache the stiffness result data in the cloud server.

[0048] For example, the data is sent to the cloud server, a serial port to Ethernet device is added, and the external network is connected via Ethernet to realize communication with the cloud server. The cloud server of this solution is a server with multi-port networking and computing capabilities, which communicates with the rolling mill control system and the grinding roller system to realize the rolling mill calibration process data collection and roller diameter data collection respectively, run the data processing machine stiffness calculation program, and finally transmit the stiffness data unidirectionally.

[0049] Exemplarily, this solution includes communicating with the rolling mill control system and other systems, realizing data collection, data analysis, screening and filtering in the cloud server, and using valid data to obtain the final stiffness value according to the stiffness calculation formula. At the same time, a diagnostic program is written in the server to realize system operation log storage, and the system operation steps, data results of each stage, communication diagnosis and fault records are displayed in the form of an interface to facilitate system debugging and maintenance. A serial port to Ethernet device is added to the system to convert the stiffness data into Ethernet form in the form of a serial port, and transmit it unidirectionally to the cloud server to realize the application display of the stiffness data.

[0050] In one embodiment, storing the rolling mill stiffness in a cloud server and sending it to a mobile terminal associated with the user includes:

[0051] The above rolling mill stiffness is stored in a cloud server based on the serial port single-phase transmission method and sent to a mobile terminal associated with the user.

[0052] For example, this method uses a one-way transmission method for stiffness data. By programming an interface program, the stiffness value is sent to a cloud server via one-way serial port transmission. This one-way serial port transmission utilizes the cloud server's serial port, taking into account its electrical characteristics, connecting only the transmit and ground wires. This achieves a send-only function, preventing the writing of external data while ensuring that users can access rolling mill stiffness data in a timely manner.

[0053] In one embodiment, the determining of the rolling mill stiffness based on the hydraulic cylinder extension amount and the rolling force includes:

[0054] Obtain roller diameter data of the grinding roller system;

[0055] The rolling mill rigidity is determined based on the hydraulic cylinder extension amount, the rolling force, and the roll diameter data.

[0056] For example, the data server's network port is directly connected to the roller grinding system. By connecting to the system, when the mill calibration process is executed, the roll diameter data of the used rolls is collected. The roll diameter data of the corresponding rolls is then retrieved from the roller grinding system's database based on the mill number calibrated by the rolling system. The mill stiffness can then be more accurately determined based on the hydraulic cylinder extension, rolling force, and roll diameter data.

[0057] In one embodiment, the method further includes:

[0058] The above rolling mill is diagnosed and recorded based on the above rolling mill stiffness and the standard rolling mill stiffness.

[0059] For example, the fault diagnosis and fault recording of this solution realizes system operation log storage through programming, and displays the system operation steps, data results of each stage, communication diagnosis and fault records in the form of an interface, which is convenient for system debugging and maintenance.

[0060] In one embodiment, the method further includes:

[0061] When the rolling force is detected to be greater than or equal to 1200 kN, the rolling force is regarded as the effective rolling force;

[0062] The rolling mill stiffness is determined based on the above-mentioned hydraulic cylinder extension amount and the above-mentioned effective rolling force.

[0063] For example, this solution starts collecting data only when the rolling force reaches 1200KN or more during the calibration process, thereby eliminating the squeezing force between components and ensuring the accuracy of the calculation.

[0064] Exemplarily, this solution deploys all acquisition, processing, calculation, forwarding, and diagnostic programs in a cloud server; the mill calibration process data acquisition method realizes production line data acquisition; the roll data acquisition method collects roll data; the data processing and stiffness calculation program runs on the cloud server, processes and calculates the data as needed; and uses a one-way networking method to transmit the data; at the same time, a system diagnostic program is written that can intuitively record the system operation status and faults, facilitating system debugging and maintenance. The mill stiffness measurement system and method provided by the present invention eliminates the process of independent stiffness measurement, increases the number of stiffness detection times, greatly shortens the rolling gap, improves the production efficiency of steel rolling, and simultaneously realizes dynamic monitoring of stiffness data, making it easier to grasp the deterioration trend of the mill and achieve preventive maintenance.
