Foil coiling system including a handling apparatus 200, wrapping apparatus 400 and coiling apparatus 300. The handling apparatus is arranged to receive a leading end of a foil sheet F expelled from a bite (103, fig 1b) of a foil mill and move the leading end so as to extend the sheet over the coiling apparatus. The wrapping apparatus is arranged to guide the sheet onto the coiling apparatus, provide a wrapping end of the sheet and wrap the sheet around a portion of the coiling apparatus. The coiling apparatus is arranged to rotate in order to coil the wrapped sheet around the coiling apparatus.

Aspects of the present invention relate to a rolling mill laying head. The rolling mill laying head comprises a quill rotatable about a central axis, said quill being equipped with a guide pathway configured and arranged to form a longitudinally moving product into a continuous series of rings; a stationary support structure; and axially spaced radial bearings supporting said quill for rotation about said axis, one of said bearings 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.

Windungsleger für aus einer Drahtwalzstraße kommenden schnellbewegten Walzdraht, bestehend aus einem ortsfest horizontal oder vertikal rotierbar gelagerten Antriebskörper und einem, drehfest mit diesem verbundenen Rohrhaltekörper, der ein Legerohr trägt, dessen Rohreneingang, dem Antriebskörper zugewandt, mit dessen Drehachse fluchtet und dessen Rohrausgang mit axialem und radialem Abstand von dem Rohreingang angeordnet ist, wobei das Legerohr in Form einer zwischen Rohreingang und Rohrausgang axial auseinandergezogenen Spirale aufweist und den in der Achsmitte des Antriebskörpers in den Rohreingang eingebrachten Walzdraht bis zu seinem Austritt aus dem Rohrausgang führt, und wobei in Achsrichtung hinter dem Rohrhaltekörper ein, mit diesem rotationsverbundener Tragkörper (TK) mit zylindrischer Außenumfangsfläche (AU) vorgesehen ist, auf der eine gewindeförmig verlaufende Führungsrinne (FR) angeordnet ist, in deren Eingangsöffnung (EU) der Rohrausgang des Legerohres mündet, und aus deren Ausgangsöffnung (AO) der aus dem Legerohr kommende Walzdraht (WD) bei seinem Austritt zu kontinuierlich aufeinanderfolgenden, kreisfömigen Windungen geformt und auf eine Weiterfördereinrichtung abgelegt wird, dadurch gekennzeichnet, dass der Abstand der einander gegenüberliegenden Führungswände (FW) der Führungsrinne (FR), ausgehend von der Eingangsöffnung (EO) zur Bildung einer trichteracrtigen Verengung (AS) stetig verkleinernd und anschließen vor Erreichen der Mitte der Gesamtlänge der Führungsrinne (FR) bis zur Ausgangsöffnung (AO) stetig erweiternd bemessen wird.
摘要:
A turndown apparatus (16) has first and second guide rollers (54a, 54b) arranged respectively along the inside and outside of a curved path (P C ) along which bendable products such as bars, rods and the like move at high speeds. The guide rollers coact in pairs to define gaps spaced along the curved path, and a mechanism (40a, 44a & 40b, 44b) is provided for symmetrically adjusting the gaps defined between the guide rollers in order to accommodate different product sizes.
摘要:
An apparatus is disclosed for receiving a continuous series of rings (16) of a hot rolled product (12) such as a rod from a rolling mill. The apparatus includes: a) a portable container (24) having:i) a vertically disposed cylindrical side wall (30) open at its upper and lower ends;ii) a base (32) at the lower end of the side wall configured to removably locate the container at a coil forming station (20);iii) a horizontal shelf (34) projecting inwardly from the interior of said side wall; andiv) a central core (38) supported by the shelf, the core being spaced inwardly from the interior of the side wall to define an annular chamber (42) therebetween, the shelf having access openings therein communicating with the chamber; b) an elevator platform (50) at the coil forming station, the elevator platform having support members (52) configured and arranged to pass through the access openings in the shelf; and c) means (56) for vertically adjusting the elevator platform to move the support members through the access openings in the shelf between raised operative positions at which the support members project into the chamber to support a coil therein by the receipt of the rings through the open upper end, and an inoperative position beneath the shelf, resulting in the coil being deposited on the shelf.
摘要:
In a rolling mill, a reforming chamber (24) is positioned to receive rings (20) of hot rolled steel rod descending along a vertical path from the delivery end of a conveyor (22) onto a support (40) on an underlying carrier (36). The carrier has an upstanding stem (42) around which the rings (20) accumulate to form a cylindrical coil C. First, interceptor elements (30) operate above the carrier (36) to interrupt the descent of rings (20), and second interceptor elements (60,62) supported on the carrier (36) beneath the first interceptor elements (30) operate to subdivide the coil C being formed around the stem (42) into upper and lower segments, with a gap therebetween occupied by the second intercepting elements (60,62).
摘要:
In an apparatus for receiving a series of loops (L) descending along a vertical path from the delivery end of a conveyor (12) and for accumulating the thus received loops (L) into an annular coil, a device for horizontally distributing the descending loops (L). The device includes a ring (18) surrounding the vertical path. The ring (18) has a cylindrical vertical wall (18a) and a radially outwardly extending horizontal ledge (18b). A curved guide member (32) extends around a segment of the ring (18) and has leading and trailing ends (32a,32b). The guide member (32) protrudes inwardly from the ring (18) into the vertical path, with the extent of the inward protrusion being greater at the trailing end (32b) than at the leading end (32a). The guide member (32) is in mechanical interengagement with the horizontal ledge (18b) and in horizontal abutting engagement with the vertical wall (18a) to thereby accommodate vertical placement and removal of the guide member (32) onto and off of the ring (18) without attendant radial displacement of the guide member (32) with respect to the ring (18).
