[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following embodiments are combined with the accompanying drawings to specifically illustrate the technical solutions of the present invention.

[0021] The embodiment of the present invention provides a KOCKS rolling mill sizing area control system, comprising: a data acquisition system, an analysis and processing system, a control execution system, and a closed-loop feedback system.

[0022] See also Figure 1The workflow of the KOCKS rolling mill sizing area control system of the present invention. The data acquisition system collects the production data of the rolling mill during the pressing process. The analysis and processing system processes the collected production data, optimizes the coefficients of the model using the processing results, and generates a control strategy through the model. The control execution system automatically adjusts the operating parameters of the rolling mill according to the control strategy. The closed-loop feedback system is used to compare the calculation results of the model of the analysis and processing system with the actual measured values ​​of subsequent production. When the error between the two exceeds the error setting range, the operating parameters are adjusted to control the operating parameters within the set error range.

[0023] The data acquisition system is provided with a detection module and a data preprocessing module. The detection module includes several force detection devices and several temperature detection devices. The detection module is used to collect production parameters such as temperature and mechanical data collected during the rolling process, including pressure, torque, and temperature.

[0024] The temperature detection device is a RIFD temperature sensor, i.e. a RIFD scanner, see Figure 2 The RIFD scanner is arranged in the roll room, including an RIFD scanner 1 for detecting the temperature of the roll changing device, an RIFD scanner 2 for detecting the temperature of the guiding device, an RIFD scanner 3 for detecting the temperature of the lubrication station, and an RIFD scanner 4 for detecting the temperature of the trolley.

[0025] The force detection device is an RSB sensor, which is used to detect mechanical parameters, including the RSB of the hydraulic pump and the oil tank (such as Figure 2 6) RSB of valve bracket (such as Figure 2 7) RSB of lubrication pump and oil tank (such as Figure 2 (8).

[0026] The data preprocessing module is used to filter out noise data from the collected production data, improve data quality, and provide more accurate raw data for subsequent processing.

[0027] The analysis and processing system is preset with corresponding calculation models for elongation, rolling torque, speed cascade, speed drop compensation, head and tail tension control, and temperature. These calculation models can use existing calculation models. Data processing and model optimization are the core. The analysis and processing system uses machine learning algorithms such as linear regression, support vector machines, and neural networks to process data. This minimizes calculation errors. To ensure the efficiency and timeliness of data processing, the system is equipped with a high-performance computing server, a multi-core processor, and a large-capacity memory, which can process large-scale data in a short time and generate optimized models. According to the optimized model, the analysis and processing system generates a real-time control strategy.

[0028] The control execution system automatically adjusts the operating parameters of the rolling mill according to the control strategy. These operating parameters include roll gap, guide position and temperature.

[0029] The control execution system includes a client, a mobile terminal, a display screen, an optical coupler, a repeater, a frequency converter, and a server.

[0030] See also Figure 2 The client includes a client engineer station 9 in the main operation room, a client engineer station 10 in the quality room, a client engineer station 11 in the roll room, and a client workstation 12 in the roll room.

[0031] The mobile terminal includes a tablet computer 13 arranged on the roller changing device, a tablet computer 14 arranged on the guiding device, a tablet computer 15 arranged on the lubrication station, and tablet computers 16 and 17 arranged on the trolley.

[0032] The display screen 18 is arranged in the main operating room and is used to display the mechanical parameter screen. The display screen adopts a touch screen.

[0033] The frequency converter is used to control the motor and adjust the mechanical parameters. The optical coupler and repeater are used to achieve automatic temperature adjustment.

[0034] The server 19 is connected to the client, the mobile terminal, the display screen, the inverter, the optical coupler and the repeater through the remote control device 20, and the server 19 is provided with a KOCKS service program.

[0035] The control execution system uses JAVA language and API to read and write database rolling table information. According to the rolling table information, the rolling mill performs main speed cascade control, cascade micro-tension control, speed drop compensation, rolled piece tracking, and rolled piece head and tail tension control.

[0036] The control execution system can automatically adjust the various operating parameters of the rolling mill. This automated parameter adjustment process not only reduces the need for manual intervention, but also greatly improves the automation level and production efficiency of the production line.

[0037] The closed-loop feedback system sets the error control range, specifically: the elongation error of the rolling pass is set within ±1%, and the rolling torque error is set within ±5%. The closed-loop feedback system is continuously optimized based on real-time feedback data. This closed-loop control process not only ensures the stability of the production process and the consistency of product quality, but also improves the system's adaptive ability and high-precision control level.

[0038] Application cases and operating results: The KOCKS rolling mill sizing area control system of the present invention was put into use in the Huaigang Special Steel Rolling Mill of Jiangsu Shagang Group. Through the application of this control, the calculation error of the elongation rate of the rolling pass is controlled within ±1%, the rolling torque error is controlled within ±5%, the free rolling tolerance is controlled within 1 / 4DIN, and the precision rolling tolerance is controlled within 1 / 5DIN or 1 / 6DIN, which significantly improves the product quality and the automation level of the production line, and the manual intervention is close to zero. The operating cost is reduced by about 15%, and the production efficiency is increased by nearly 20%, which fully proves the technical advantages and application prospects of the scheme of the present invention.
