The analysis of the causes of the ski-effect of the sheet in the hot rolling conditions in the plate mill 5000 was performed. Influence of kinematic, thermal and geometrical factors on the occurrence of the ski-effect of the sheet were investigated. Influence of the velocity asymmetry of work rolls on bending of the front end of a sheet was studied in detail. Influence of parameters of the rolling process and the velocity asymmetry of work rolls on the shape of the front end of the sheet for different passes were analyzed. Modes of asymmetric rolling alloy pipe steels in the plate mill 5000 were developed and simulated with using software DEFORM. The problem of flatness formation of the sheet was also studied. Industrial tests were performed in the plate mill 5000. Specific asymmetric rolling modes and recommendations for industry were developed. Results of research can be applied to any type of plate mill with independently adjustable velocity of the upper and lower work rolls.Keywords: Asymmetrical rolling, plate rolling, finite element method, vertical bending, sheet’s front section, temperature gradient
