Problems solved by technology
[0002] In the production process of the cold-rolled acid tandem rolling line, due to the defects caused by the hot-rolled raw material coils, it is easy to cause edge defects and roll damage defects of the rolling mill
However, frequent strip breakage or roll damage incidents in the acid rolling line, and if the strip breakage or roll damage incidents are not discovered in time, there will be a strip breakage accident in the rolling mill or damage to the roll, so that subsequent steel coils are prone to batch roll mark defects , causing great hidden dangers to production smoothness and product quality

The invention relates to the field of cold-rolling and acid-cold-rolling technologies, in particular to a rolling mill protection method and a rolling mill protection device for an acid continuous rolling production line. The rolling mill protection method comprises the steps of: detecting surface defects of a rolling mill in the acid continuous rolling production line, so as to obtain surface defect information used for representing surface defect situations of the rolling mill; judging whether a preset alarm condition is met in a pre-established surface defect classification model based on the surface defect information; and if so, generating alarm information to prompt a user to perform a corresponding disposal operation. According to the rolling mill protection method and the rolling mill protection device, the surface defect classification model is established in advance, the surface defect information of the rolling mill in the acid continuous rolling production line is obtainedthrough detection, whether the preset alarm condition is met is judged in the surface defect classification model based on the surface defect information, and the alarm information is generated so asto prompt the user to perform the corresponding disposal operation if the preset alarm condition is met, thus a surface defect type event can be found timely and precisely, and the occurrence of a surface defect type accident can be avoided.
