Apply online grinding roll technology and work roll traverse to reduce roll wear, extend the rolling kilometers of the strip, and reduce the number of roll changes.
The damage of the roll is caused by the interaction and mutual influence of many factors, and its damage forms are various. Although roll damage cannot be completely avoided in actual work, we can propose corresponding solutions for specific damage forms; we can also consider the material selection of rolls according to the use environment of the rolls to ensure that the rolls can withstand heat with large temperature changes. Fatigue effect; the wear of rolls can also be reduced by rationally arranging the roll changing cycle, rationally arranging cooling water and rolling lubrication, and applying online grinding roll technology.
In summary, roll breakage and deep cracks on the working face are irreversible losses. There are many reasons. Strict control of material composition, forging process, reasonable processing, reasonable arrangement of heat treatment, and use of rolls in strict accordance with roll usage rules can effectively reduce roll cracking. frequency.
