“…In the past, numerous investigators [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] have proposed various models for the prediction and control of the strip profile. Their models are mostly based on three constituent elementary models-an elementary model for the analysis of the deflection of the work rolls and backup rolls, such as the slit beam model, 19) an elementary model for the analysis of roll flattening, such as a semi-infinite solid model, 20) and an elementary model for the prediction of the roll force distributions along the strip width, such as a slab model.…”

A full, finite element (FE)-based approach is presented for the precision analysis of the strip profile in flat rolling. Basic FE models for the analysis of the mechanical behavior of the strip and of the rolls are described in detail. Also described is an iterative strategy for a rigorous treatment of the mechanical contact occurring at the roll-strip interface and at the roll-roll interface. Then, presented is an integrated FE process model for the coupled analysis of the mechanical behavior of the strip, work roll, and backup roll in four-high mill. A series of process simulation are conducted and the results are compared with the measurements made in hot and cold rolling experiments.
