Online calculation model of rolling force for cold rolling mill based on numerical integration

Comparison of Roll Deformation in 4hi Rolling Mill and 20 Hi Rolling Mill Due to Thermal Stresses, Overloading, Spalling and Design Parameters

“…The deformation of work roll of rolling mill has been divided in three sections named as Entry Elastic Deformation zone, Plastic Deformation zone, and Exit Deformation zone as shown in Fig below [26]…”

A Numerical Procedure Based on Orowan’s Theory for Predicting the Behavior of the Cold Rolling Mill Process in Full Film Lubrication

“…Rolling mill models considering the presence of lubricants are presented in some works in the scientific literature [15][16][17][18][19][20][21][22][23]. Lugt et al [21] presented a model of the rolling mill process, also considering the metal strip elastic deformation in the inlet and outlet zone.…”

“…The novelty of the proposed model over the models presented in the works of [1][2][3][4][5][6][7][8][9][10][11] is that the influence of lubricants is considered. The novelty with respect to the presented previous models [12][13][14][15][16][17][18][19][20][21][22][23] is that the new model combines Orowan's inhomogeneous theory [24] for plastic deformation with the Reynolds equation in full film lubrication and the continuity conditions. The new proposed model presented in this paper and the previous model based on the slab analysis [23] share the representation of the lubrication regime, the mathematical procedure, and the boundary conditions, but in the new model, the plastic deformation of metal strips is described by means of Orowan's inhomogeneous theory, instead of the slab analysis.…”
