Modernization of Helical Rolling Technology in a Multi-Roll Mill …
Abstract An analysis of the helical rolling process shows that the change in the axial speed of the roll along the length of the groove of the cross-roller mill does not correspond to the required nature of the change in the speed of the deformed billet. The process proceeds under intense axial compression, as a result of which a significant part …
