The mathematical method for the determining of the optimal technological parameters of the cold straightening of the thick steel sheet on the twelve-rolled sheet-straightening machine is proposed. The calculations allow us to determine the type and the curvature of the neutral line of the steel sheet under the straightening depending on the rolls’ radius, the pitch between the straightening machines’ working rolls, the magnitude of the sheet reduction by the upper rollers, the sheet thickness, as well as the elastic modulus, the yield stress and the hardening modulus of the sheet metal. The results of the research can be used at the metallurgical plants.
