THIN-WALLED AXISYMMETRIC STEEL SHELL MANUFACTURING METHOD

摘要

FIELD: metallurgy.;SUBSTANCE: rotational extraction of hollow billets by deforming rollers is made with different profile angles, installed with different gaps with a mandrel. Rollers with different front and rear angles are used. In this case, the rollers are installed with a successive change of angles from the roller with a smaller front and large rear profile angle to each subsequent roller with larger front and smaller rear profile angles and with a consequent reduction in gaps relative to the mandrel.;EFFECT: high accuracy of dimensions and quality of the processed membranes surface.;8 cl, 3 dwg
