FIELD: information technology.

SUBSTANCE: invention relates to a method for determining the length of the arc of contact during longitudinal rolling of a strip on a smooth barrel. Method includes determining parameters of the investigated process of longitudinal rolling and computer simulation of the investigated rolling process in a two-dimensional setting using values of previously determined parameters of the investigated longitudinal rolling process. Computer simulation of the investigated rolling process is carried out by finite-element computer simulation of the investigated process of longitudinal rolling with the help of tools of a computing environment of finite-element analysis. Upon completion of finite-element computer simulation of the investigated process of longitudinal rolling, the contact area of the strip with the selected roll is displayed, determining coordinates along the abscissa of the points located in the contact area and having the largest and smallest coordinates along the abscissa among all points of the contact area of the strip and the selected roll, coordinates of the center of the selected roll are determined. In a computer-aided design environment, a flat drawing is created, in which points are created with coordinates corresponding to coordinates of said points with maximum and minimum coordinates along abscissa among points of contact of strip and selected roll, and point is created, which is center of selected roll. In the created drawing, an arc is built through the above three points using the computer-aided design environment.

EFFECT: higher accuracy of calculation of power parameters of rolling process.
