ABSTRACT
The explanation of the mechanism of elimination of the yield plateau as a result of skin pass rolling sheet steels, based on the provisions of the theory of dislocations, is consistent the interpretation of this effect from the standpoint of the appearance of residual stresses in the metal. Cold-rolled steel sheets are mainly skin pass rolled on single-stand rolling mills. Depending on the degree of deformation during skin pass rolling the yield strength of steel sheets is initially lowered with respect to value for the metal not processed by skin pass rolling. Maintaining the compression in the said narrow range is difficult because the skin pass rolling process parameters vary for different coils of the steel sheet and also within one coil. When skin pass rolling sheet steel in the mills equipped with roller bearings of the working and supporting rolls, the speed increase reduces the degree of deformation of the strips of all thickness.
