072066000 | COILING BY WORK-GUIDE MEMBER ORBITING ABOUT LONGITUDINAL CENTERLINE OF FORMED COIL | 8 |
20090249852 | ROLLING MILL POURING REEL AND ITS METHOD OF OPERATION - A pouring reel for forming a long product moving at an incoming velocity into an annular coil comprises a central mast lying on a vertical axis. A cylindrical tub surrounds and cooperates with the mast to form an annular chamber, the bottom of which is closed by a coil plate. An entry pipe is arranged to deliver the product downwardly for accumulation in the chamber as a series of superimposed rings forming the annular coil. A first drive mechanism rotates the tub about the vertical axis, and a second drive mechanism rotates the mast about the same axis. The first and second drive mechanisms are operable independently of each other to thereby permit the tub and the mast to be rotated at surface velocities substantially matching the incoming velocity of the product. | 10-08-2009 |
20110072873 | METHOD FOR SHAPING A BARREL SPRING MADE OF METALLIC GLASS - The invention relates to a method for shaping a barrel spring made of a unitary ribbon of metallic glass that comprises calculating the theoretical shape to be given to said unitary ribbon of metallic glass so that each segment, once the spring is fitted in the barrel, is subjected to the maximum bending momentum, shaping said ribbon by imparting bends thereto characteristic of said free theoretical shape in order to take into account a potential reduction of the bends once the ribbon is released, relaxing the ribbon in order to set the shape thereof by heating the same, and cooling down said ribbon. | 03-31-2011 |
20120055218 | REGENERATIVE LAYING PIPE - A laying pipe configured for rotation about its axis in a rolling mill laying head, comprises a ferrous outer tube having an entry section aligned with its axis, an intermediate section curving away from its axis, and a delivery section having a constant radius measured from its axis. A ferrous inner tube has entry, intermediate and delivery sections respectively lining the entry, intermediate and delivery sections of the outer tube. The inner tube is constrained against movement relative to the outer tube solely by frictional contact with the outer tube. The inner tube is movable incrementally within the outer tube in one direction in response to heating and cooling cycles during rotation of the laying pipe about its axis. | 03-08-2012 |
20120079862 | BORONIZED LAYING PIPE - A laying pipe for use in the laying head of a rolling mill is configured for rotation about an axis, with an entry end aligned on that axis to receive a hot rolled product, and with a curved section leading to a delivery end spaced radially from that axis. The curved section defines a guide path configured to form the hot rolled product into a helical formation of rings. The laying pipe comprises a tubular ferrous wall having an interior surface comprising a wear resistant boronized layer against which the hot rolled product is confined for movement along the guide path. | 04-05-2012 |
20130074562 | ROLLING MILL LAYING HEAD PIPE HAVING MODULAR CONSTRUCTION - A rolling mill coil-forming apparatus includes a rotating quill that supports an elongated path hollow structure, such as a laying head pipe, for receiving elongated material after it has been rolled. A portion or the entire elongated structure is formed from modular, selectively replaceable components. The fabricated modular structures facilitate formation of zones within the component, such as including by way of example wear-resistant zones, material transport guide structures and friction reducing zones. | 03-28-2013 |
20130333432 | WINDING DEVICE AND WINDING METHOD FOR EDGEWISE COIL - A winding device includes a bending mechanism for bending a rectangular wire, a feed mechanism for feeding the rectangular wire, a coil guide for supporting an edgewise coil formed by alternately repeating the feeding of the rectangular wire by the feed mechanism and the bending of the rectangular wire by the bending mechanism, and a coil-guide moving mechanism for moving the coil guide while rotating the coil guide. The coil guide includes a guide column to be brought into engagement with an inner circumference of a first coil portion having a cylindrical shape, and a guide base on which a second coil portion is to be placed, the second coil portion having a cylindrical shape connected to the first coil portion through a connecting wire and having a center axis that is shifted in position from a center axis of the first coil portion to form a stepwise shape. | 12-19-2013 |
