A spindle for pilgrim-process rolling mill.

摘要

On a pilgrim-process rolling mill (1), a mandrel (10) is held locked against radial movement within a cradle-shaped seat (12) formed in a spindle (8) by a head (19) having a lug (20) and being guided for movement in the spindle into and out of an operative position where the lug (20) overlies the tang (9) of the mandrel (10); no specific machining of the mandrel tang being necessary to have it locked in the cradle seat, such a spindle can directly accept mandrels from existing pilgrim-process rolling mills.
