AI Technical Summary
Technical Problem
During the rolling process, it is difficult to accurately identify damaged work rolls, which leads to increased roll consumption costs.
Method used
By identifying the first stand as the one with the larger elongation among the two target stands of the rolling mill, and the second stand as the one with the smaller elongation, and by changing the diameter of their work rolls to increase the difference in the new roll diameter, and combining this with the actual roll mark length of the strip, the damaged work rolls can be accurately identified.
Benefits of technology
It enables accurate identification of damaged work rolls, reduces roll consumption costs, and improves production efficiency.

Abstract
This invention discloses a method, apparatus, equipment, and medium for determining damaged work rolls. The method includes: identifying the target stand with the larger elongation among two target stands of a rolling mill as the first stand, and the target stand with the smaller elongation among the two target stands as the second stand; replacing the work rolls on the first stand with work rolls of a first diameter and / or replacing the work rolls on the second stand with work rolls of a second diameter; after replacement, recording the diameter of the work rolls on the first stand as the first new diameter, and the diameter of the work rolls on the second stand as the second new diameter, wherein the first new diameter is greater than the second new diameter, or a second difference between the second new diameter and the first new diameter is greater than a preset second difference threshold; obtaining the actual roll mark length of the strip; and determining the damaged work roll based on the first new diameter, the second new diameter, the elongation, and the actual roll mark length. This method can accurately determine which stand's work roll is damaged.
