[0003] Since hot-rolled stainless steel plates have low hardness, are easy to process, have good ductility and good corrosion resistance, they can be used to make containers for corrosive liquids. In order to ensure the reliability and safety of the containers, the corrosion resistance of the hot-rolled stainless steel plates needs to be tested.

[0004] Cutting a piece of hot-rolled stainless steel plate as a sample, making the sample contact with a corrosive test solution for a period of time, and then observing the corrosion of the sample is one of the common methods for testing the corrosion resistance of hot-rolled stainless steel plates in the prior art. During the test, the test solution is easy to splash onto the technicians, and the volatilization of the test solution will also pose a certain threat to the health of the technicians. In addition, after the sample is in contact with the test solution, a large amount of test solution will remain on the sample, and the sample needs to be manually rinsed, which is not only troublesome but also has certain safety hazards. Therefore, we propose a corrosion resistance test device for hot-rolled stainless steel plates. Summary of the invention

A detection button is provided on the corrosion detection controller 002, and the detection button is signal-connected with the corrosion detection master control module.

[0037] See also Figure 1 and Figure 4 A support frame 116 is also fixedly installed on the waste liquid tank 101, and a lifting cylinder 117 is fixedly installed on the support frame 116. The output end of the lifting cylinder 117 is fixedly connected to a sample pressing plate 118. The sample pressing plate 118 is located directly above the corrosion-sensitive sample tube 102, and the corrosion detection master control module is connected to the lifting cylinder 117 signal.

[0038] See also Figure 1-5 , a method for using the detection device comprises the following steps:

[0039] S1. Cut a hot-rolled stainless steel plate of suitable size as a test sample, place the test sample on the top of the corrosion sample placement tube 102, and reasonably set a time parameter through the parameter setting module according to the test requirements, and then press the test button to send a test instruction to the corrosion detection control module;

[0040] S1.5, the corrosion inspection master control module starts the lifting cylinder 117, so that the lifting cylinder 117 drives the pressing plate 118 to move downward until the pressing plate 118 abuts against the inspection sample;

[0041] S2, the corrosion detection master control module opens the corrosion guide solenoid valve 115 to introduce an appropriate amount of detection solution into the interior of the corrosion-contacting sample tube 102 and above the sealing partition 103, so that the bottom end of the sample contacts the detection solution;

[0042] S3. After the detection solution is introduced, the corrosion detection master control module closes the corrosion solution conduit 113 and sends a signal to the timing reminder module to start timing;

[0043] S4, when the timing reminder module reaches the time parameter set above, the timing reminder module will send a signal to the corrosion detection master control module. After receiving the signal, the corrosion detection master control module will open the waste guide solenoid valve 105 to discharge the detection solution above the sealing partition 103 into the waste liquid tank 101, and then the corrosion detection master control module will start the push-pull cylinder 111 to make the push-pull cylinder 111 push the sealed water guide block 106 until the water guide hole 107 moves to the inside of the corrosion-contacting sample tube 102;

[0044] S5, the corrosion detection master control module opens the water guide solenoid valve 114, so that the water in the water supply pipe is sprayed toward the test sample through the water supply sleeve connecting pipe 109, the water guide pipe 108, the water guide hole 107, and the wide-angle nozzle 119, so that the residual test solution on the test sample can be washed away. After 10-30 seconds, the washing is completed, and the corrosion detection master control module will close the water guide solenoid valve 114 and the waste guide solenoid valve 105;

[0045] S5.5, the corrosion inspection master control module starts the lifting cylinder 117, so that the lifting cylinder 117 drives the pressure plate 118 to move upward and reset;

[0046] S6. The corrosion detection master control module sends a signal to the timing reminder module, causing the timing reminder module to emit a prompt tone indicating the end of the detection. After hearing the prompt tone, the test sample can be removed and the corrosion condition of the test sample can be observed.

[0047] Through the joint setting of the corrosion detection actuator and the corrosion detection controller 002, during the detection, the relevant technicians only need to place the detection sample on the corrosion-sensitive sample tube 102 and press the detection button on the corrosion detection controller 002. The corrosion detection controller 002 will automatically control the corrosion detection actuator to perform corrosion resistance detection on the sample. It has less manual operation and a high degree of automation, and can effectively prevent the detection solution from splashing onto the staff. During the detection process, the detection solution is in a relatively sealed environment, which can effectively prevent the volatilization of the detection solution from endangering the health of the technicians. When the detection is completed, the residual detection solution on the sample can be automatically rinsed off, which can not only improve the detection efficiency, but also greatly improve the safety during detection.

[0048] By setting the lifting cylinder 117, the pressing plate 118, etc., the pressing plate 118 can fix the test sample after it is against the test sample, preventing the test solution from leaking or overflowing, thereby improving the safety and reliability of the test equipment and further improving the safety during testing.

[0049] The second implementation method:

[0050] Figure 6-8 A corrosion resistance testing device for hot-rolled stainless steel plates is shown. Different from the first embodiment, a detection control module is also provided in the corrosion detection controller 002, and the corrosion detection master control module is signal-connected with the detection control module. A detection leak-proof component is also provided on the corrosion sample tube 102, and the detection leak-proof component includes a support cylinder 301 fixedly mounted on the outer wall of the waste liquid tank 101, and a plurality of detection lamps 302 evenly distributed along a ring are fixedly mounted on the inner side of the support cylinder 301. The detection leak-proof component also includes a brightness sensor 303 fixedly mounted on the inner wall of the corrosion sample tube 102, the top of the support cylinder 301 is set to an opening shape, and the top of the support cylinder 301 is flush with the top of the corrosion sample tube 102, and the detection leak-proof component also includes an alarm fixedly mounted on the waste liquid tank 101, and the detection control module is signal-connected with the detection lamp 302, the brightness sensor 303 and the alarm.

[0051] When the bottom of the test sample is uneven, the test sample will not be able to fit completely with the corrosion sample tube 102, which will cause leakage of the test solution. In order to avoid this situation, during the corrosion resistance test of the hot-rolled stainless steel plate, the corrosion detection master control module starts the lifting cylinder 117, so that the lifting cylinder 117 drives the pressing plate 118 to move downward, so that the pressing plate 118 is against the test sample, and before opening the corrosion solution conduit 113, the corrosion detection master control module will first send a signal to the inspection control module, so that the inspection control module controls the inspection anti-leakage component to check whether the test sample is completely fitted with the corrosion sample tube 102. After receiving the signal, the inspection control module The brightness sensor 303 will be started to monitor the change of the brightness inside the corrosion sample tube 102, and the brightness data monitored by the brightness sensor 303 will be transmitted to the inspection control module, and then the inspection control module will light up all the inspection lamps 302. If the test sample can be completely fitted with the corrosion sample tube 102, the light emitted by the inspection lamp 302 is difficult to penetrate the inside of the corrosion sample tube 102, and the brightness data monitored by the brightness sensor 303 will not change significantly. At this time, the inspection control module will send a signal of inspection passing to the corrosion inspection master control module, and then the corrosion inspection master control module will open the corrosion fluid conduit 113 and continue to proceed. The corrosion resistance test is performed. On the contrary, if the test sample cannot be completely fitted with the corrosion-sensitive sample tube 102, light will be injected into the inner side of the corrosion-sensitive sample tube 102 at the non-fitting position, so that the brightness data detected by the brightness sensor 303 will change significantly. At this time, the inspection control module will send a signal of inspection failure to the corrosion inspection master control module, causing the corrosion inspection master control module to stop the inspection, and control the lifting cylinder 117 to drive the pressure sample plate 118 to move upward and reset. At the same time, the inspection control module will also activate the alarm. In addition, after the inspection is completed, no matter what the inspection result is, the inspection control module will automatically turn off the inspection light 302 and the brightness sensor 303. Therefore, through the joint setting of the corrosion detection controller 002 and the corrosion detection leak-proof component, before the detection solution is introduced into the corrosion sample tube 102, the corrosion detection control module will control the corrosion detection leak-proof component to check the fit between the detection sample and the corrosion sample tube 102. If the inspection finds that the detection sample fails to fully fit with the corrosion sample tube 102, the corrosion resistance test will be automatically stopped and the alarm will be activated to remind relevant technical personnel, thereby effectively avoiding the leakage of the detection solution due to the failure of the detection sample to fully fit with the corrosion sample tube 102, thereby further improving the safety and reliability of the detection equipment, and further improving the safety during detection.

[0052] See also Figure 7A reflective coating is provided on the inner wall of the support cylinder 301, which is conducive to the propagation of light and improves the accuracy of inspection. The outer cover of the brightness sensor 303 is provided with a matching transparent protective cover 304. The transparent protective cover 304 is sealed and fixedly connected to the inner wall of the corrosion-resistant sample tube 102, and the transparent protective cover 304 is made of transparent corrosion-resistant material. The transparent protective cover 304 can protect the brightness sensor 303 without affecting the inspection, thereby preventing the brightness sensor 303 from being corroded and damaged by the detection solution.

[0053] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
