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