Profile and Flatness Control Technology With a Long Shifting Stroke on Wide Non-Oriented Electrical Steel Sheets

Keywords： silicon steel , shape control , hot rolling , roll contour ,

In order to solve the difficult profile and flatness control problem of wide non-oriented electrical steel sheets, the factors such as the relationship between strip crown control and strip width, the relationship between the maximum wearing value of work roll and the number of a rolling campaign and the wear contour change of work roll were analyzed on the basis of industrial test. Through analyzing the rolling process characteristics of non-oriented e- lectrical steel sheets, the ASR （asymmetry self-compensating work rolls） shape control technology and its roll shift- ing strategy of the wider non-oriented electrical steel sheets was proposed and developed. When the technology was applied, the number of the wide non-oriented electrical steel （2.3 mm× 1 280 mm） in one rolling campaign rose from 40 coils of the trial production to 70 coils of the industrial production, the ratio of the measured strip crown less than 45 um was increased from 50.0% to 94.9%, and the ratio of the measured strip crown more than 60 um was decreased from 20.0% to 0.7%.
