Laying head for rod rolling mill

摘要

In a laying head for forming a longitudinally moving hot rolled product into a helix, a tubular quill has a central axis of rotation and a through passageway extending along the central axis from a first end to an opposite second end of the quill. The interior quill surface has a cylindrical section leading from the first end of the passageway to a radially outwardly flared section which in turn leads to the second end of the passageway. A laying pipe is received in the through passageway. The laying pipe has an entry end aligned with the central axis at the first end of the passageway, a curved intermediate portion surrounded by the flared section of the interior quill surface, and an end portion projecting axially from the second end of the passageway to a delivery end spaced radially from the central axis. A first support at the first end of the passageway radially supports the entry end of the laying pipe, and a second support projects axially into the passageway from the second end of the quill to provide support for the curved intermediate portion of the laying pipe.
