Research on the Work Roll Wear Model and Parameters on 2250 CVC Hot Strip Mills

Through tracing and testing,it was found that the work roll for 2250 CVC hot strip mills in hot rolling had the problems of serious and non-uniform wear.In order to solve the problem,the wear regular of work rolls on 2250 Hot Strip Mills had been researched.The wear mechanism of work rolls in hot strip mills is analysed.Based on sufficient experimental data,a theoretical calculating model of roll wear were set up for the first time.This essay concentrate on the definition of the key parameters by a kind of optimized genetic algorithm.The conclusion can not only effectively applied to the off-line analysis of work roll wear,but also make an accurate work roll wear prediction on the rolling spot.
