Capabilities of grooves forming articulated profiles for rolling – separation technology

Abstract

The emerging growth of industrial and civil construction in Russia and introduction of new technologies have caused the need to increase the production of construction rolled products and, especially, rebar. One of the ways to increase rebar production at existing mills in the shortest possible time without serious capital investments is the use of rolling – separation technology. For successful implementation of this technology, the conditions for the feasibility of this process are given in this report. New dependences were obtained for determining the longitudinal force provided by the reserve of friction forces during formation of an articulated profile taking into account the profile shape and the conditions of shape change.
