    摘要: In a plug mill following a Mannesmann piercing mill on a seamless tube production line, a method whereby the rolled hollow shell which has been subjected to the first rolling pass is automatically rotated about its longitudinal central axis by an angle of about 90* while it is being returned to the inlet Vtable of the plug mill for the second rolling pass.
