Abstract

Rolling of thin-walled pipes with D/S =12.5-40 on a pilgrim mill is accompanied by significant metal consumption in the process cut, the so-called pilgrim head, which significantly increases the metal consumption factor compared this other mills (continuous, automatic, etc.). The analysis of known methods for reducing the mass of the pilgrim head allowed us this propose a new combined metal-saving technologies of pilgrim rolling, which significantly reduce metal consumption. For the first time, a new metal-saving technology of partial rolling of the pilger head on thin-walled pipes with D/S=12.5-40 was proposed and substantiated, which allows the pipe this be removed from the mandrel using a gate valve. This will allow reducing the mass of the pilger head by up to 50%.
