Rolling process of 2 mm corrosion-resistant hot-rolled coiled plate

The invention relates to a rolling process of a 2 mm corrosion-resistant hot-rolled coiled plate. The rolling process comprises the following steps: detecting the flatness of a first position, a second position, a third position and a fourth position of a metal plate by utilizing a flatness detector to generate a real-time flatness matrix P (P1, P2, P3, P4), wherein the first position is arrangedbetween a first finishing mill and a second finishing mill, the second position is arranged between the second finishing mill and a third finishing mill, the third position is arranged between the third finishing mill and a fourth finishing mill, and the fourth position is arranged between the fourth finishing mill and a fifth finishing mill; and according to changes of the first real-time flatness and the second real-time flatness, adjusting the roller rotating speed and the rotating speed difference of the fourth finishing mill and the fifth finishing mill. The follow-up rotating speed and rotating speed difference of the fourth finishing mill and the fifth finishing mill are adjusted according to the changes of the flatness of the first position and the second position, the metal plateswith the flatness not meeting the requirement are corrected in time, real-time feedback is conducted, and accurate adjustment of the flatness of the metal plates is achieved.
