[0032] In order to solve the above technical problems, according to the first aspect of the present application, the present application proposes a safety control device for the accident water system of a slab caster. Figure 1 A schematic block diagram of a slab caster accident water system safety control device 100 provided in an embodiment of the present application, Figure 2 A structural schematic diagram of a slab caster accident water system safety control device 200 provided in an embodiment of the present application, as shown in FIG. Figure 1-2 As shown, the device 100 may include: a cooling water system 110 , an emergency water system 120 , and a controller 130 .

[0033] The cooling water system 110 includes a first main pipeline 1110 and a plurality of first branch pipelines 1120 .

[0034] Exemplarily, the cooling water system 110 may include: a cooling water pump, wherein the cooling water pump may form a cooling water pump station 1101. The starting end of the first main pipeline 1110 may be directly connected to the cooling water pump station 1101, and the terminal of the first branch pipeline 1120 branches to form a plurality of first branch pipelines 1120. The pipeline ends of the plurality of first branch pipelines 1120 are respectively connected to a single continuous casting machine 10, and the continuous casting machine 10 is respectively provided with a crystallizer and a fan-shaped segment. It should be noted that in the cooling water system 110, the cooling water flows from the cooling water pump station 1101 through the first main pipeline 1110, and then flows to the first branch pipeline 1120, and then flows to the fan-shaped segment through the crystallizer through the first branch pipeline 1120, and the cooling water flowing out of the fan-shaped segment is finally collected in the same pipeline and flows out.

[0035] The plurality of pressure sensors 1102 are respectively disposed inside the first main pipeline 1110 and the plurality of first branch pipelines 1120 for detecting the pressure of water in the pipelines, wherein the number of the plurality of pressure sensors 1102 corresponds to the number of pipelines in a one-to-one correspondence.

[0036] It should be noted that the pressure sensor 1102 disposed inside the first main pipeline 1110 is used to detect the pressure data of the first main pipeline 1110. The pressure sensor 1102 disposed inside the first branch pipeline 1120 is used to detect the pressure data of each branch of the continuous casting machine 10.

[0037] The emergency water system 120 includes a second main pipeline 1210 and a plurality of second branch pipelines 1220 , and switches are respectively provided on the plurality of second branch pipelines 1220 .

[0038] Exemplarily, the above-mentioned accident water system 120 may include an accident water tank 1201, a liquid level meter 1203 and a water supply valve 1202. The liquid level meter 1203 is arranged in the accident water tank 1201, and is used to detect the liquid level data of the accident water tank 1201. The water supply valve 1202 is arranged at the water inlet end of the accident water tank 1201.

[0039] It should be noted that the starting end of the second main pipeline 1210 can be directly connected to the accident water tank 1201, and a plurality of second branch pipelines 1220 are formed at the end of the second main pipeline 1210, and the pipeline ends of the second branch pipelines 1220 are respectively connected to the first branch pipelines 1120, so that the accident water can flow to the cooling water system 110 through the first branch pipeline 1120, wherein switches can be respectively provided on the plurality of second branch pipelines 1220 to achieve separate control of each second branch pipeline 1220. The switch can be a normally closed switch, specifically, when the pressure data detected by the pressure sensor 1102 is abnormal, the switch can be changed from a closed state to an open state, so that the accident water can flow to the cooling water system 110.

[0040] The controller 130 is used to control the switch on the second branch pipeline 1220 connected to the first main pipeline 1110 and / or the first branch pipeline 1120 where the pressure abnormality data appears to be turned on when the amount of pressure abnormality data in the detected pressure exceeds a preset percentage, so that the accident water system 120 supplies water to the pipeline where the pressure abnormality data appears in the cooling water system 110, wherein the pressure value of the pressure abnormality data is less than or equal to the preset pressure value.

[0041] It should be noted that the above-mentioned preset percentage and the above-mentioned preset pressure value can be set according to actual needs. Among them, the above-mentioned preset percentage is negatively correlated with the user's safety needs, that is, the higher the user's safety needs, the smaller the above-mentioned preset percentage. The above-mentioned preset pressure value is positively correlated with the user's safety needs, that is, the higher the user's safety needs, the higher the above-mentioned preset pressure value, wherein the above-mentioned preset pressure values ​​can be set separately based on the corresponding safety needs of the continuous casting machine 10.

[0042] Exemplarily, the above-mentioned preset percentage can be 50%. Specifically, when the ratio of the number of data less than or equal to the preset pressure value to the total amount of pressure data in the pressure data detected by the pressure sensor 1102 is greater than 50%, the control switch is turned on to allow the accident water system 120 to supply water to the pipeline in the cooling water system 110 where abnormal pressure data appears.

[0043] Based on this, the safety control device of the slab casting machine accident water system 120 provided in the present application is configured with a first main pipeline 1110 and multiple first branch pipelines 1120; multiple pressure sensors 1102 are respectively arranged inside the first main pipeline 1110 and multiple first branch pipelines 1120, for detecting the pressure from water in the pipeline, and the number of multiple pressure sensors 1102 has a one-to-one correspondence with the number of pipelines, and the water pressure of the first main pipeline 1110 and the multiple first branch pipelines 1120 can be accurately monitored; the accident water system 120 includes a second main pipeline 1210 and multiple second branch pipelines 1220, and switches are respectively arranged on the multiple second branch pipelines 1220, which can accurately target and regulate the on-off status of each second branch pipeline 1220; the controller 130 is used to detect the abnormal pressure data in the detected When the quantity in the pressure accounts for more than a preset percentage, the switch on the second branch pipeline 1220 connected to the first main pipeline 1110 and / or the first branch pipeline 1120 where abnormal pressure data appears is controlled to be turned on, so that the accident water system 120 supplies water to the pipeline where abnormal pressure data appears in the cooling water system 110, wherein the pressure value of the abnormal pressure data is less than or equal to the preset pressure value. When the water pressure data of the first main pipeline 1110 and / or the first branch pipeline 1120 is abnormal, the switch on the corresponding second branch pipeline 1220 is controlled to be turned on, so as to accurately control the accident water system 120 to supply water to the pipeline where abnormal pressure data appears in the cooling water system 110, thereby avoiding false alarms due to abnormalities in the sensor itself, improving the control accuracy of the water flow direction, and improving the safety of the processing process of the continuous casting machine 10.

[0044] In some feasible implementations, the switch in the emergency water system 120 includes a normally open switch 1222 and a second check valve 1223 .

[0045] Exemplarily, when the proportion of abnormal pressure data in the detected pressure exceeds a preset percentage, since the switch in the accident water system 120 is composed of a normally open switch 1222 and a second check valve 1223, the first main pipeline 1110 and / or the first branch pipeline 1120 and the second branch pipeline 1220 connected thereto are in a connected state, and the accident water can push open the check valve and automatically replenish the first main pipeline 1110 and / or the first branch pipeline 1120 to ensure that the pressure level of the cooling water system 110 is maintained at the battlefield level. At the same time, the configuration of the check valve can prevent the accident water from flowing back to the accident water system 120, which is beneficial to maintaining the stability of the accident water system 120.

[0046] It should be noted that in the prior art, the switch valves in the emergency water system 120 are mostly normally closed valves. Since the normally closed valves are in a closed state for a long time, the valve body is prone to rust and jamming, resulting in the inability of emergency water to flow to the continuous casting machine 10. The switch in the emergency water system 120 of the present application is set to a normally open switch 1222 and a second check valve 1223, which can avoid valve body rust and jamming, and the cooling water emergency water cannot be replenished to the cooling water system 110, thereby avoiding safety accidents caused by insufficient cooling water and excessive temperature in the casting machine crystallizer or fan-shaped segment, thereby improving the operating safety of the continuous casting machine 10.

[0047] In some feasible implementations, the controller 130 is also used to generate an alarm signal when abnormal pressure data appears in the detected pressure; the device also includes: an alarm system for generating an alarm in response to the alarm signal.

[0048] Exemplarily, the alarm system may include: a horn and / or a warning light, etc.

[0049] In some feasible embodiments, the controller 130 can generate an alarm signal when abnormal pressure data appears in the detected pressure, and send the alarm signal to the alarm system to trigger the speaker to emit a sharp beep and / or the warning sound to flash, which is beneficial to improve the alarm accuracy of the alarm system.

[0050] In some feasible embodiments, the controller 130 can also generate an alarm signal when the proportion of abnormal pressure data in the detected pressure exceeds a preset percentage, and send the alarm signal to the alarm system to trigger the speaker to emit a sharp alarm sound and / or the alarm sound to flash, which is beneficial to improve the alarm accuracy of the alarm system, reduce the false alarm rate of the alarm system, and maintain the normal production of the continuous casting machine 10.

[0051] In some feasible implementations, the switch further includes a manual valve 1221 .

[0052] It should be noted that each first branch pipeline 1120 may be provided with a manual valve 1221 to perform maintenance on the first main pipeline 1110 and / or the first branch pipeline 1120 when abnormal pressure data appears in the detected pressure.

[0053] Based on this, the above-mentioned slab caster emergency water system 120 safety control device can improve the maintenance efficiency of the cooling water system 110 by configuring the above-mentioned manual valve 1221.

[0054] In some feasible implementations, a first check valve 1121 is respectively provided on the plurality of first branch pipelines 1120 .

[0055] It should be noted that a first check valve 1121 is respectively provided on multiple first branch pipelines 1120, which is helpful to prevent the cooling water flowing to the continuous casting machine 10 from flowing back, resulting in insufficient cooling water flow and excessive temperature of the crystallizer or fan-shaped segment of the continuous casting machine 10, causing a safety accident.

[0056] In the second aspect, the present application proposes a slab caster accident water system safety control method, which is applicable to the slab caster accident water system safety control device as described in any of the above items. Specifically, the above slab caster accident water system safety control method 200 can be implemented based on a PLC (Programmable Logic Controller) program.

[0057] For example, Figure 3 A slab caster accident water system safety control method 200 is provided in an embodiment of the present application, such as Figure 3 The illustrated method 200 may include the following steps:

[0058] Step S110 , detecting the internal pressures of the first main pipeline and the plurality of first branch pipelines.

[0059] Exemplarily, pressure sensors may be provided inside the first main pipeline and the plurality of first branch pipelines, respectively, to detect the internal pressures of the first main pipeline and the plurality of first branch pipelines.

[0060] Step S120, when the amount of abnormal pressure data in the detected pressure accounts for more than a preset percentage, control the switch on the second branch pipeline connected to the first main pipeline and / or the first branch pipeline where the abnormal pressure data appears to be turned on, so that the accident water system supplies water to the pipeline in the cooling water system where the abnormal pressure data appears, wherein the pressure value of the abnormal pressure data is less than or equal to the preset pressure value.

[0061] It should be noted that the above-mentioned preset percentage and the above-mentioned preset pressure value can be set according to actual needs. Among them, the above-mentioned preset percentage is negatively correlated with the user's safety needs, that is, the higher the user's safety needs, the smaller the above-mentioned preset percentage. The above-mentioned preset pressure value is positively correlated with the user's safety needs, that is, the higher the user's safety needs, the higher the above-mentioned preset pressure value, wherein the above-mentioned preset pressure values ​​can be set based on the safety needs of the corresponding continuous casting machine.

[0062] Exemplarily, the preset percentage may be 50%. Specifically, when the ratio of the number of pressure data detected by the pressure sensor that is less than or equal to the preset pressure value to the total amount of pressure data is greater than 50%, the control switch is turned on to allow the accident water system to supply water to the pipeline in the cooling water system where abnormal pressure data appears.

[0063] Based on this, the present application provides a safety control method for the accident water system of a slab casting machine. By detecting the internal pressure of a first main pipeline and multiple first branch pipelines, when the number of abnormal pressure data in the detected pressure accounts for more than a preset percentage, the switch on the second branch pipeline connected to the first main pipeline and / or the first branch pipeline where the abnormal pressure data appears is controlled to be turned on, so that the accident water system supplies water to the pipeline in the cooling water system where the abnormal pressure data appears, wherein the pressure value of the abnormal pressure data is less than or equal to the preset pressure value, and precise targeted regulation of the on-off status of each second branch pipeline can be achieved. When the water pressure data of the first main pipeline and / or the first branch pipeline is abnormal, the switch on the corresponding second branch pipeline is controlled to be turned on, so as to accurately control the accident water system to supply water to the pipeline in the cooling water system where the abnormal pressure data appears, thereby avoiding false alarms due to abnormalities in the sensor itself, improving the control accuracy of the water flow direction, and improving the safety of the continuous casting machine processing process.

[0064] In some feasible implementations, the method 200 may further include:

[0065] Step S130, when abnormal pressure data appears in the detected pressure, an alarm signal is generated to issue an alarm based on the alarm signal.

[0066] Exemplarily, the alarm system may include: a horn and / or a warning light, etc.

[0067] In some feasible embodiments, the controller can generate an alarm signal when abnormal pressure data appears in the detected pressure, and send the alarm signal to the alarm system to trigger the speaker to emit a sharp beep and / or the warning sound to flash, which is beneficial to improve the alarm accuracy of the alarm system.

[0068] In some feasible embodiments, the controller can also generate an alarm signal when the proportion of abnormal pressure data in the detected pressure exceeds a preset percentage, and send the alarm signal to the alarm system to trigger the speaker to emit a sharp alarm sound and / or the warning sound to flash, which is beneficial to improve the alarm accuracy of the alarm system, reduce the false alarm rate of the alarm system, and maintain the normal production of the continuous casting machine.

[0069] In some feasible implementations, a first check valve is respectively provided on the plurality of first branch pipelines, and the method 200 may further include:

[0070] Step S140, in the process of the accident water system supplying water to the pipeline in the cooling water system where abnormal pressure data appears, the first check valve operates.

[0071] It should be noted that a first check valve is respectively arranged on multiple first branch pipelines. In the process of supplying water from the accident water system to the pipeline where abnormal pressure data appears in the cooling water system, the above-mentioned first check valve works, which is beneficial to avoid the backflow of cooling water flowing to the continuous casting machine, resulting in insufficient cooling water flow and excessive temperature of the continuous casting machine crystallizer or fan-shaped segment, causing a safety accident.

Figure 4 As shown, the electronic device 300 may include a processor 310 and a memory 320. The memory 320 stores computer program instructions, which are used by the processor 310 to execute the above-mentioned safety control method for the accident water system of the slab caster when the computer program instructions are executed.

The storage medium may include, for example, a storage component of a tablet computer, a hard disk of a computer, a read-only memory (ROM), an erasable programmable read-only memory (EPROM), a portable compact disk read-only memory (CD-ROM), a USB memory, or any combination of the above storage media.
