[0025] In some embodiments, as Figure 1 As shown, an embodiment of the present application provides a control method for a continuous casting machine, comprising:

[0026] Step S101, during the operation of the crystallizer, obtaining the real-time taper value of the crystallizer;

[0027] Step S102: When the real-time taper value is greater than a first taper threshold value and less than a second taper threshold value within a preset first time period, the alarm device is controlled to output a first alarm and the enabling valve is controlled to remain in an open state to allow the crystallizer to continue operating.

[0028] Step S103: When the real-time taper value is greater than the second taper threshold value within the preset second time period, the alarm device is controlled to output a second alarm and the enabling valve is controlled to switch to a closed state to stop the crystallizer from working.

[0029] In this embodiment, a control method for a continuous casting machine is proposed, wherein the continuous casting machine includes components such as a crystallizer, an alarm device, and an enabling valve.

[0030] Illustratively, the enable valve is used to control the start or stop of the crystallizer.

[0031] For example, the alarm device may output an audible or visual alarm.

[0032] During the operation of the crystallizer, a real-time taper value of the crystallizer is obtained, wherein the real-time taper value represents the real-time taper of the crystallizer.

[0033] For example, the real-time taper value of the crystallizer can be obtained through a sensor.

[0034] Within a preset first time period, when the real-time taper value is greater than the first taper threshold and less than the second taper threshold, the alarm device is controlled to output a first alarm and the enabling valve is controlled to remain in an open state to allow the crystallizer to continue working.

[0035] Among them, the first duration is a preset duration, the first taper threshold and the second taper threshold are preset thresholds, the second taper threshold is greater than the first taper threshold, and the first alarm is an alarm for abnormal taper, indicating that the taper of the crystallizer is abnormal, but it can continue to operate.

[0036] Exemplarily, the first duration may be 2 seconds.

[0037] Exemplarily, the first taper threshold may be 0.2 mm.

[0038] Exemplarily, the second taper threshold may be 1 mm.

[0039] When the real-time taper value is greater than the second taper threshold within the preset second time period, the alarm device is controlled to output a second alarm and the enabling valve is controlled to switch to a closed state to stop the crystallizer from working.

[0040] The second duration is a preset duration, which is shorter than the first duration. The second alarm is an alarm indicating a taper failure, indicating that the taper of the crystallizer fails and the crystallizer needs to stop working.

[0041] Exemplarily, the second duration may be 0.25 seconds.

[0042] For example, after the crystallizer stops working, the staff is notified to repair the crystallizer.

[0043] It should be noted that during the casting process, in the non-width adjustment mode, if the actual taper deviates from the set taper by between 0.2 and 1 mm within 2 seconds, the program will issue a drive deviation warning and will not shut off the enabling valve. If the actual taper deviates from the set taper by more than 1 mm within 0.25 seconds, the program will alarm and shut off the enabling valve. By relaxing the taper alarm threshold and increasing the detection frequency, the continuous casting machine's operational stability is ensured, thereby improving its operating efficiency.

[0044] The control method of the continuous casting machine in this embodiment improves the operating stability of the continuous casting machine, thereby improving the operating efficiency of the continuous casting machine.

[0045] In some embodiments, an embodiment of the present application provides a method for controlling a continuous casting machine, and the method for controlling the continuous casting machine further includes:

[0046] Step S201, during the operation of the crystallizer, obtaining the valve position value of the servo valve;

[0047] Step S202: When the valve position value is greater than a preset valve position threshold, the alarm device is controlled to output a third alarm.

[0048] In this embodiment, the continuous casting machine further comprises a servo valve, which is a valve for modulating the flow and pressure in the oil cylinder.

[0049] Exemplarily, the servo valve may be an electromagnetic servo valve.

[0050] During the operation of the crystallizer, a valve position value of the servo valve is obtained, wherein the valve position value represents the valve position of the servo valve.

[0051] For example, the valve position value may be expressed as a percentage, such as 3%.

[0052] When the valve position value is greater than a preset valve position threshold, the alarm device is controlled to output a third alarm, wherein the third alarm is an alarm indicating that a servo valve is faulty.

[0053] Exemplarily, the valve position threshold may be 1.59%.

[0054] For example, a comparative analysis of the servo valve position change trends during the taper alarm and during normal casting revealed that the average servo valve position output during the alarm was 7.37%, significantly higher than the 1.59% average servo valve position during normal casting. During normal casting, the servo valve's maximum position remained within 3%. A program was added to monitor the width adjustment servo valve's position status. If the servo valve's maximum position exceeded 3.5% during casting, an alarm would pop up on the first-level HMI screen, prompting equipment maintenance personnel to monitor and inspect the servo valve. This monitoring would reduce mold taper alarms caused by servo valve degradation.

[0055] In some embodiments, an embodiment of the present application provides a method for controlling a continuous casting machine, and the method for controlling the continuous casting machine further includes:

[0056] Step S301, during the operation of the crystallizer, obtaining the output voltage value of the DC power supply;

[0057] Step S302: When the output voltage value is less than a preset voltage threshold, the alarm device is controlled to output a fourth alarm.

[0058] In this embodiment, the continuous casting machine further includes a DC power supply, which is used to supply power to a load inside the continuous casting machine.

[0059] During the operation of the crystallizer, an output voltage value of the DC power supply is obtained, wherein the output voltage value represents the output voltage of the DC power supply.

[0060] Exemplarily, the output voltage value may be 21V.

[0061] When the output voltage value is less than the preset voltage threshold, the alarm device is controlled to output a fourth alarm, wherein the fourth alarm is an alarm indicating that a fault exists in the DC power supply.

[0062] Exemplarily, the voltage threshold may be 24V.

[0063] For example, the DC power supply may be a 24V redundant power supply to improve the power supply stability of the control system and reduce taper alarms caused by power failures.

[0064] For example, 24V power supply voltage status monitoring is added. When the power supply voltage of the servo valve, position sensor, and pressure relay is lower than 21V, a fourth alarm pops up on the first-level human-machine interface to remind maintenance personnel to check the 24V power supply and reduce taper alarms caused by abnormal power supply voltage.

[0065] In some embodiments, an embodiment of the present application provides a control method for a continuous casting machine, which obtains a real-time taper value of a crystallizer, comprising:

[0066] Step S401, controlling the position sensor to collect position information of the oil cylinder;

[0067] Step S402: Determine the real-time taper value according to the position information.

[0068] In this embodiment, the continuous casting machine further includes a position sensor and an oil cylinder, and the position sensor is controlled to collect position information of the oil cylinder, wherein the position information represents an offset position of the oil cylinder.

[0069] For example, the position information may include three-dimensional offset coordinate data of the cylinder.

[0070] The position information is processed to obtain the real-time taper value.

[0071] In some embodiments, an embodiment of the present application provides a control method for a continuous casting machine, which controls a position sensor to collect position information of an oil cylinder, including:

[0072] Step S501, controlling the first sensor to collect a first position offset value of the oil cylinder;

[0073] Step S502, controlling the second sensor to collect a second position offset value of the oil cylinder;

[0074] Step S503, controlling the third sensor to collect a third position offset value of the oil cylinder;

[0075] Step S504: Control the fourth sensor to collect a fourth position offset value of the oil cylinder.

[0076] In this embodiment, the position sensor includes a first sensor, a second sensor, a third sensor, and a fourth sensor, and the position information includes a first position offset value, a second position offset value, a third position offset value, and a fourth position offset value.

[0077] The first sensor is controlled to collect the first position offset value of the oil cylinder, the second sensor is controlled to collect the second position offset value of the oil cylinder, the third sensor is controlled to collect the third position offset value of the oil cylinder, and the fourth sensor is controlled to collect the fourth position offset value of the oil cylinder.

[0078] It should be noted that the first sensor is set in the first direction of the cylinder, the second sensor is set in the second direction of the cylinder, the third sensor is set in the third direction of the cylinder, and the fourth sensor is set in the fourth direction of the cylinder. The first direction is parallel to the second direction, the third direction is parallel to the fourth direction, and the first direction is perpendicular to the third direction, and the second direction is perpendicular to the fourth direction.

[0079] Exemplarily, the first position offset value, the second position offset value, the third position offset value, and the fourth position offset value all include coordinate data.

[0080] In some embodiments, an embodiment of the present application provides a control method for a continuous casting machine, which determines a real-time taper value based on position information, including:

[0081] Step S601, calculating the difference between the first position offset value and the second position offset value to obtain a first offset difference;

[0082] Step S602, calculating the difference between the third position offset value and the fourth position offset value to obtain a second offset difference;

[0083] Step S603: determining a real-time taper value according to the first offset difference and the second offset difference.

[0084] In this embodiment, a difference between the first position offset value and the second position offset value is calculated to obtain a first offset difference value, wherein the first offset difference value is a difference between the first position offset value and the second position offset value.

[0085] A difference between the third position offset value and the fourth position offset value is calculated to obtain a second offset difference value, wherein the second offset difference value is a difference between the first position offset value and the second position offset value.

[0086] A real-time taper value is determined according to the first offset difference and the second offset difference.

[0087] Exemplarily, the first offset difference and the second offset difference are compared, and the maximum value of the first offset difference and the second offset difference is determined as the real-time taper value.

[0088] Exemplarily, an average value of the first offset difference and the second offset difference is determined as the real-time taper value.

[0106] Exemplarily, the second duration may be 0.25 seconds.
