The study on the dynamic parameters of the bending rollers in coilbox

Based on the theory of the elastoplastic distortion and using the correlative knowledge about the case of geometrical blending distortion,we discussed how to calculate the roll gap of three rollers coilbox,constructed the mathematic models concerning the control of the raising vector of the bending rollers in coillbox on the basis of it,and drew the control graphics for vector in the case of variational raising vector.The fruit can bring certain reference for the home made design and manufacture of the coilbox device.
