Effect of Roll Diameter on Hot Roll Strip Profile by Analytic Modelling

采用影响函数法开发了热轧带钢凸度影响率计算软件,研究了轧辊直径对热轧带钢凸度的影响规律,得出了四辊轧机工作辊和支撑辊直径影响率基本值的5次多项式拟合系数及工作辊直径和支撑辊直径对轧辊直径影响率的修正指数,建立了高精度轧辊直径影响率计算的数学模型,为板形控制模型参数的计算提供了理论依据·

?A calculation software was developed by Gmethod to examine the effect regularity of roll diameter on hot roll strip profile. The quintic multinomial fitting coefficients of work roll diameter and backup roll diameter's influence ratios( ground value) in 4high mill were calculated separately, the revised indexes of the diameter of work roll and backup roll to roll diameter's influence ratio were found. The high accuracy calculation module of roll diameter's influence ratio was built. The present work offers theoretical basis for the optimization of strip profile control module's coefficients.
