| description | The invention discloses a rolling mill roll gap deviation adjusting method and system, and the method comprises the following steps: (1) calculating the roll gap deviation Si of the working side and the transmission side of the current ith rack based on a vertical roll steel biting signal; (2) the roll gap deviation Si is issued to the ith rack, and the roll gap of the ith rack is adjusted based on the roll gap deviation Si; the roll gap deviation Si is composed of a roll gap deviation base value S1i needed by the rolling force difference of the operation side and the transmission side during zero adjustment, a primary roll gap deviation compensation value delta S1i needed for eliminating the asymmetric factor of the intermediate billet and a secondary roll gap deviation compensation value delta S2i used for compensating the roll gap deviation S1i + delta S1i. The roll gap deviation of each rolling mill is automatically calculated and issued according to the zero-adjustment rolling force difference of the rol |
