Steel plate detection direction is opposite with steel plate direction of transfer；
When steel plate head reaches cold checking device, surface detection apparatus work；
When steel plate tail leaves hot checking device, surface detection apparatus is stopped；
Check that surface of steel plate whether there is or not impression, is completed to search according to the result of surface detection apparatus detection.
The technical solution that the present invention further limits is：
Further, in the aforementioned method for quickly searching straightener roll marks using table check system, step（2）In, when No. 2 cold inspection dresses
It sets when detecting steel plate head, No. 2 cold checking devices give surface detection apparatus one rising edge signal, receive rising edge signal
When, surface detection apparatus lamp box operating pneumatic；
When No. 1 cold checking device detects steel plate head, No. 1 cold checking device gives surface detection apparatus one rising edge signal,
When receiving rising edge signal, surface detection apparatus camera starts work；
When hot checking device detects that steel plate tail is left, hot checking device gives surface detection apparatus one failing edge signal, surface
Detection device closes lamp box and camera.
In the aforementioned method for quickly searching straightener roll marks using table check system, not less than No. 1 cold inspection dress of length of steel plate
Set the distance between No. 2 cold checking devices.
In the aforementioned method for quickly searching straightener roll marks using table check system, after straightening roll produces a certain amount of steel plate,
Operative employee tests a straightening roll impression.
Technique effect can check whether this method is effective using artificial test, if having omission, if any can be timely
Stop, avoiding the appearance of high-volume substandard product, wastes the working time, reduce cost.
The beneficial effects of the invention are as follows：
The present invention, which provides, quickly finds straightening roll abrasion place, avoids the appearance of high-volume substandard product, this method logical in time
Optimization straightener program is crossed, the measurement direction of Surface testing is changed, realizes that online discovery defect, timely reconditioning straightening roll improve
The lumber recovery of steel plate.
After the present invention comes into operation, by periodically testing to steel plate, after finding defect, it is quickly found out straightening roll abrasion
Position, timely reconditioning, is greatly saved the production time, improves the lumber recovery of steel plate.
By daily reconditioning 3 times, save 5 minutes every time, year benefit=360*0.25*200*500=9,000,000.
It is unplanned to occur daily primary by being found after 30 minutes, unplanned 360*0.5*200=3.6 ten thousand can be reduced within 1 year
Ton.
