Forming of band curvature in asymmetrical rolling process

In this work, the analysis of asymmetric continuous rolling process of band in two last stands of finishing group of plate rolling mill is presented. The analysis is used to obtain the range of admissible values of roll speed asymmetry coefficient for adequate grade of steel and to obtain admissible curvature of the band on output from deformation zone and also diminishing of the force pressure of the metal on rolls without overload the drives of finishing group of plate rolling mill. Research project included an influence of relative reduction ε, roll speed asymmetry ratio av and shape of deformation zone coefficient ld/hsr on band curvature ρ.
