The three-dimensional plastic deformation of strip were analyzed by stream surface strip element method,the elastic deformations of rolls were analyzed by influence coefficient method,the analyzing and computing model of shape and crown of the strip rolled on 4-high CVC mill were established by combining them,and the rolling process of hot strip on 4-high CVC continuous mills was simulated.

CVC roll crown coefficients in F1～F3 stands of finishing mill was analyzed by five-order curves.

CVC roll shifting calculation model of a certain domestic hot strip mill was presented and the main mathematic model was discussed.

Mathematical resolution of CVC roll contour used in CSP production line is conducted and roll contour function of CVC rolls was obtained.

Large amount of measured data on roll wear of CVC mill in CSP production line were obtained and different roll wear patterns from F1 to F7 were investigated.

The structure, design concept and application of CVC mills are introduced.

It reviewed the CVC cold rolling mill,aviation aluminium materials and high speed train aluminium materials,saving energy and reduction emission,thick plate production line,safety production,aluminium fabrication equipment export,and so on.
