Electroplastic rolling method capable of implementing independent control in transverse zones

An electroplastic rolling method capable of implementing independent control in transverse zones. The positions of conductive copper rings in respective electroplastic shape control roller systems are determined on the basis of the positions of strip shape defects; by means of a control circuit, it is ensured that two electroplastic shape control roller systems and a strip form an electrical loop, such that electroplastic regulation is implemented in transverse zones along the strip; a variation in the plastic deformation resistance of the strip is determined on the basis of an impact matrix method, and a local heating temperature of the electroplastic shape control roller systems is then determined in view of a deformation resistance and temperature rheological curve relationship of the strip; and online temperature regulation in the direction of width of the strip is realized at an entry of a deformation zone by means of the electroplastic shape control roller systems.
