Abstract In order to solve various flatness problems in the process of thin strip rolling,a new type of electromagnetic control rolling mill was used as the research object, and a three-dimensional thermal-mechanical coupling finite element model was established by Marc, and the bending force under the combined action of the bending roll and the electromagnetic control roll was analyzed. And the rolling force affected the roll shape state, plate shape distribution, slab edge stress, roller contact stress, and bearing roll gap shape.The results show that the application of the roll bending mechanism will directly promote the stable bulging of the electromagnetically controlled rolls,and the bulging crown of the electromagnetically controlled rolls will be compensated integrally. Based on the good shape of the plate,a reasonable bending roll for the new electromagnetically controlled rolling mill is given. Comparing the changes of roll gap functions with different bending forces and rolling forces,different secondary and fourth crowns are formed,which provides a basis for shape control and initial roll gap settings.

Key words： roll bending mechanism electromagnetic regulation crown compensation bearing roll gap rolling mill
