“…For simulating the press anvil and the edger tools (rollers), analytical rigid bodies are employed. Coulomb friction model with friction coefficient of 0.35 is used for modeling the contact between the workpiece and tools both in the vertical rolling and SP processes (Chun et al, 2003(Chun et al, , 2005Shangwu et al, 2000aShangwu et al, ,b, 2001Shangwu et al, , 2003.…”

“…In the past, research on the edging technology have been mainly carried out by experiments [9], theoretical analysis [10][11][12][13][14] and finite element method (FEM) analysis [8,[20][21][22][23][24][25]. Okado et al [5] simulated vertical rolling processes at a laboratory mill and formulated dog-bone shapes by regression analysis of the simulated results.…”

This paper clarified the formation mechanism of the uneven shapes of a wide and heavy plate during vertical rolling (edging). Coordinate movements of material from the plate length center were constrained by both the rolled part and the to-be-rolled part during the steady edging phase. Then the higher dog-bone height and the shorter dog-bone length were formed around plate length center part, comparing to dog-bone shapes formed at plate head and plate tail. During the plate head edging phase, the main plastic deformation zone extended from the roller-plate contact zone to the plate head. Only the to-be-rolled part constrained deformation of material from the main plastic deformation zone, so it was easier for material flew into its width direction as well as its length direction than it did during the steady edging phase. Coordinate movements of the rolled material led to the width shortage around the plate head zone and increased the plate head concave shape. During the plate tail edging phase, the main plastic deformation zone extended from the roller-plate contact zone to the plate tail. Deformation constrain from the to-be rolled part disappeared gradually while that from the rolled part worked through the plate tail edging. Material of the main deformation zone flew into its width direction as well as its length direction more easily than it did during the steady edging too. Coordinate movements of the to-be rolled material increased the plate tail concave shape. The research results provided deep understanding for SSC in plate/strip edging and guidelines to develop new methods for plate/strip plan view pattern control.

“…David et al [8] studied the influence of friction coefficient on the dogbone formation process in edge rolling by using the penalty function calculation method of visco-plastic FEM, and the calculated value of dog-bone shape parameters was consistent with the measured data, but the result of rolling force was greatly deviated. Xiong et al [9] proposed a 3-dimensional model to discuss the utilization of the slightly compressible FEM to analyze edge rolling force and dog-bone shape, and obtained the relationships among section profile after edge rolling, rolling parameters and other influence factors. Unfortunately, although the results obtained by the FEM are accurate, it is not applicable for on-line automatic control in practical production due to the large amount of computation time.…”

This study presents a new mathematical model for edge rolling force and dog-bone shape using the combination of slip-line and exponent velocity field. The slip-line field of the dog-bone area is drawn out based on the deformation characteristics of edge rolling and the maximal depth of dog-bone zone is determined. Then a new exponent velocity field and corresponding strain rate field which satisfy kinematically admissible condition are proposed to analyze the edge rolling force based on upper bound approach. The upper bound solutions of dog-bone shape and rolling force are obtained by minimizing the total power which contains the internal plastic power, frictional and shear powers. The effects of reduction rate, initial thickness and roll radius on dog-bone shape size and edge rolling force are discussed. The results obtained by the combined solution in this paper are compared with measured data in strip hot rolling field and finite element method (FEM) simulation results, and a good agreement is found. Keywords Combined solution of edge rolling force • Slip-line field • Dog-bone shape • Exponent velocity field • Upper bound approach • FEM
