ROLLING PROCESS AND RELATING LONGITUDINAL, MULTI-STAND ROLLING MILL OF CONTINUOUS, RESTRAINED TYPE FOR HOLLOW BODIES

摘要

A longitudinal, multi-stand rolling mill of the continuous, restrained type for rolling hollow bodies is described, which comprises a main rolling mill (2) and an extracting rolling mill (4) in line and downstream of the main rolling mill, at a distance from the main rolling mill larger than the maximum length of the hollow body and of the spindle, and in which the spindle is extracted at the outlet of the main rolling mill in the gap between said main rolling mill and extracting rolling mill, and is laterally unloaded.
