Abstract (en)
[origin: WO2014204609A1] Aspects of the present invention relate to a rolling mill laying head. The rolling mill laying head (22) comprises a quill (24) rotatable about a central axis (X), said quill (24) being equipped with a guide pathway (26) configured and arranged to form a longitudinally moving product into a continuous series of rings; a stationary support structure (28); and axially spaced radial bearings (30, 32) supporting said quill (24) for rotation about said axis (X), one of said bearings (32) comprising a hydrostatic oil film bearing having an internal diameter of at least about 500 mm, and having a L/D ratio less than 0.25.
