Keywords： PC rolling mill

The character of the deformation zone on pair cross rolls is different from that of the regular 4-high mill.Considering comprehensive influences of normal stress and shear stress in rolling direction, width direction and thicknessdirection, the rolling force calculation model of the PC (pair crossed) hot strip mill is built. Taking the entry stress and the exit stress of strip as the boundary conditions, the longitudinal and transverse distribution of rolling force is worked out by the differential method. Then the total rolling force is calculated, and calculated results are verified by experimental data.
