SMS group GmbH: Cold pilger mills

Cold pilgering is a rolling process for metal tubes that reduces diameters and wall thicknesses. The Process. Located inside the tube is a stationary mandrel (1) which tapers in the rolling direction. This is attached to a long mandrel bar (2) which is secured in, and rotated by, a thrust block. Two dies (3) "form" the tubular stock in the same way that a rolling pin rolls out pastry.

PERFECTION OF PROCESSES OF SEAMLESS STEEL TUBES

mills; helical floating-mandrel rolling in a three-roll Assel mill and helical disk reeling in a Diescher mill. By the end of 1930 y., rolling schemes using plug and pil-grim mills were used most widely. Small quantities of tubes were produced using push benches and Assel and Diescher mills and continuous mandrel rolling was not actually used.
