摘要: 根據1700mm熱連軋機采集的現場數據分析了硅鋼軋制工作輥磨損的規律和其磨損輪廓曲線.采用中部磨損和邊部磨損分別建立磨損計算函數的方式,建立了無取向硅鋼軋制的工作輥磨損預報模型.采用遺傳算法優化計算了模型參數.現場實測數據驗證表明,模型預報精度可靠實用,可用于指導生產實踐.Abstract: Work roll wear contours and wear profiles were analyzed on the basis of large amount of measured work roll contour patterns and processing parameters. The method of building wear calculation functions for center portion abrasion and marginal abrasion respectively was used to develop a work roll wear prediction mathematical model for the 1700mm hot strip mill of Wuhan Iron and Steel (Group) Co. by using genetic algorithm. The calculated results of the prediction model are in good agreement with the measured ones and can be applied to guide production in practice.
