The results of modelling of an angle-type section with a wing height of more than (15-20)s by the rolling method were presented.

The wing that is rolled becomes long to the fullest extent at the end and to the minimum extent - at the angle area of the section. So, it acquires a longitudinal radius.

According to the results of the studies, the maximum deformation occurs near the end of the section and it was equal to (16-18)%, if the radius was 290 mm.

Processing conditions were selected by changing the parameters of rollers reduction. These conditions made it possible to produce finished products of the required diameter.
