通过采用六次偶函数拟合轧后带材的断面形状，将求解辊系弹性变形的影响函数法与求解金属横向流动的变分法相结合，模拟了轧制过程中带材的板形及轧后断面形状。该理论对冷轧机断面形状和板形的综合控制具有重大意义。
By fitting the cross-sectional shape of the strip after the rolling with six even-number functions, the influence function method for solving the elastic deformation of the roller system is combined with the variational method for solving the transverse flow of the metal to simulate the strip shape and rolling of the strip during rolling After the cross-sectional shape. This theory is of great significance to the comprehensive control of the cross-section shape and plate shape of the cold rolling mill.
