摘　　要：为了建立高精度的热轧带钢凸度计算数学模型,采用影响函数法开发了四辊轧机热轧带钢凸度影响率计算软件;系统地研究了工作辊弯辊力对带钢凸度的影响规律,得出了工作辊弯辊力影响率基本值和工作辊直径、单位宽度轧制力、压下量对弯辊力影响率修正指数的6次项拟合系数,建立了高精度工作辊弯辊力影响率的计算模型,为优化板形控制参数提供了理论依据。In order to build the high accuracy calculation mathematic model of hot rolled strip profile, the Influence Efficiency Calculation Software was developed by Gmethod for researching the regularity of effect of roll bending force on hot rolled strip profile. The numbers, the ground influence ratio of work roll bending force in 4high mill were calculated and the hexad multinomial fitting coefficients of work roll bending force influence ratio revised indexes by work roll diameter, division draught pressure and reduction were found. The high accuracy calculation model of work roll bending force influence ratio was constructed. A theoretical basis was afforded for controlling strip profile.
