【Abstract】 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.更多还原
