Method for analyzing influence of thermal crown on plate shape in cold continuous rolling process

According to the method for analyzing the influence of the thermal convexity on the plate shape in the cold continuous rolling process, from the perspective of numerical simulation, firstly, a working roller thermal convexity numerical simulation model of each rack is established through large finite element analysis software ANSYS, and thermal mechanism coupling analysis is carried out on a working roller to obtain the working roller thermal convexity of the working roller of each rack; on the basis of the thermal convexity, a rolling process numerical simulation model of each rack is established in combination with display dynamics finite element analysis software LS-DYNA, and the working roller thermal convexity of the working roller of each rack is introduced into the rolling process numerical simulation model to simulate and analyze plate shapes under different working roller thermal convexity conditions; and the genetic effect of the upstream rack is comprehensively considered, so that the influence of
