Research of Work Roll Same Width Rolling Kilometer for Local High Point Control

For the urgent need of meeting market and saving energy, the research of work roll same width rolling kilometer was put forward, and the simulation system of strip profile was established based on coupling the metal deformation model and rolls elastic deformation model etc. Taking local high point of strip as control object, the relationship between same width rolling kilometer and local high point was researched in different rolling mode. The simulated calculation and production experiment shows that work roll rolling kilometer is obviously restricted by same width strip in ordinary rolling mode, compared to ordinary mode, the reasonable shift roll rolling can greatly improve same width rolling kilometer, and local high point of strip is effectively controlled, therefore the research results has the important direction meaning and practical value for organizing production and making change roll system.
