Production of seamless pipe in a pilger mill with new groove configurations

Abstract

New groove configurations for the pilger mill reduce the nonuniformity of sleeve deformation on transition from the striker to the polishing section and enhance pipe quality. The rolling of 08X18H10Tsteel-Ш pipe blanks (produced by electroslag remelting) by the new method to obtain intermediate pipes is considered. Machining of the intermediate pipes--boring and turning--produces commercial pipe of diameter 530 and 630 mm corresponding to Technical Specifications TU 14-3R-197-2001.
