Предложен математический метод определения оптимальных технологических параметров предварительной холодной правки стального листа на семироликовой листоправильной машине. Расчеты позволяют определить вид и кривизну нейтральной плоскости стального листа при и после правки в зависимости от радиуса рабочих роликов, шага между роликами листоправильной машины, величины обжатия листа верхними роликами, толщины листа, а также модуля Юнга, предела текучести и модуля упрочнения металла листа. Результаты исследований могут быть использованы на металлургических заводах при производстве широкого листа и толстостенных труб для магистральных трубопроводов.

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.
