Work roll wear prediction model of non-oriented electrical steel sheets in hot strip mills

摘要: 根据1700mm热连轧机采集的现场数据分析了硅钢轧制工作辊磨损的规律和其磨损轮廓曲线．采用中部磨损和边部磨损分别建立磨损计算函数的方式,建立了无取向硅钢轧制的工作辊磨损预报模型．采用遗传算法优化计算了模型参数．现场实测数据验证表明,模型预报精度可靠实用,可用于指导生产实践．

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.
