Abstract

Mfg. process for seamless tubes by means of cross- and Pilger-rolling, starting with an ingot heated to rolling temperature which is press pierced, reduced in wall thickness and elongated by cross rolling with an internal plug and the elongated pierced billet without bottom is finish rolled in a Pilger mill. The pierced ingot without bottom is cross rolled with the former bottom side leading and reversed 180 deg prior to Pilger rolling.
