20080196469 | MODULAR ROLLING MILL - A modular rolling mill comprises a plurality of rolling units having work rolls configured and arranged to progressively reduce the cross sectional area of a product received along a mill pass line. Gear units are mechanically coupled to each rolling unit, with each gear unit in turn being mechanically coupled to a driven line shaft by first bevel gear sets. The ratios of the first bevel gear sets progressively increase from the first to the last of the gear units to thereby accommodate a progressively increasing speed of the product being rolled. A second bevel gear set is associated with the last gear unit. The ratio of the second bevel gear set is the same as the ratio of the first level gear set of the penultimate gear unit. The line shaft is selectively coupled to the last gear unit via one or the other of its first and second bevel gear sets. | 08-21-2008 |
20080237383 | METHOD OF CONTROLLING THE SPEED OF A LAYING HEAD IN A ROLLING MILL - A method is disclosed for controlling the speed of a curved rotatably driven laying pipe through which a longitudinally moving product is directed to exit from the delivery end of the pipe as a helical formation of rings. The method comprises determining the maximum and minimum internal radii R | 10-02-2008 |
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 |
20100242560 | APPARATUS FOR DECELERATING AND TEMPORARILY ACCUMULATING HOT ROLLED PRODUCT - An apparatus is disclosed for decelerating and temporarily accumulating a hot rolled product moving longitudinally along a first axis at a first velocity V | 09-30-2010 |
20110048093 | Method of rolling feed products into different sized finished products - A feed product is rolled into different sized finished products in a rolling mill finishing section which comprises a plurality of modular rolling units arranged along the mill pass line. Each rolling unit includes two roll stands with work rolls configured to define successive oval and round roll passes. The roll stands are designed to effect specific area reductions on products rolled through their respective oval and round roll passes. Feed products having the same entry size are rolled into finished products having different reduced sizes by providing altered rolling sequences in which a selected rolling unit is replaced along the pass line with rolling units having roll stands designed to effect area reductions that differ from those of the roll stands of the replaced rolling unit. Rolling units downstream from the replaced rolling unit are removed from the pass line. The roll stands of rolling units upstream from the replaced rolling unit remain unchanged. | 03-03-2011 |
20110100082 | Side Looper - A side looper comprises an entry guide for directing a longitudinally moving long product into an arcuate path, an exit guide for receiving the product exiting from the arcuate path, and inner and outer guide walls arranged between the entry and exit guides. The guide walls are adjustable between mutually spaced closed positions fixing the curvature of the arcuate path, and open positions allowing the curvature of the arcuate path to either increase or decrease. | 05-05-2011 |
20110265667 | BAR BUNDLER - Apparatus for bundling bars comprising an accumulator rotatable about a horizontal axis. The accumulator has a plurality of notches spaced angularly around its axis. A drive rotates the accumulator about its axis to sequentially locate the notches at:

20110302983 | MODULAR ROLLING MILL - A modular rolling mill has a mill pass line along which products are rolled in a rolling direction. The rolling mill comprises first gear units arranged along a first line parallel to the mill pass mill line. Each first gear unit is driven individually by a motor and has a pair of mechanically interconnected output shafts. Second gear units are arranged along a second line between and parallel to both the first line and the mill pass line. Each second gear unit has a pair of mechanically interconnected input shafts driving a pair of output shafts. Rolling units are arranged in succession along the mill pass line. Each rolling unit is driven by an input shaft and has a pair of mechanically interconnected roll shafts carrying work rolls. First couplings connect the output shafts of each first gear unit to input shafts of two successive gear units, and second couplings releasably connect the output shafts of the second gear units to the input shafts of two successive rolling units. | 12-15-2011 |
20120151983 | METHOD OF OPERATING AN APPARATUS FOR DECELERATING AND TEMPORARILY ACCUMULATING HOT ROLLED LONG PRODUCTS - A method for operating an apparatus for decelerating and temporarily accumulating a hot rolled long product. The product is deposited on a rotating drum in the form of a helix, and is simultaneously unwound from the drum to a receiving guide movable incrementally along a path parallel to the rotational axis of the drum. Immediately upon entry of the product front end into the receiving guide, the incremental movement of the receiving guide is preceded by an initial rapid shifting through a distance adequate to prevent subsequent product convolutions of the helix from budding and overlapping. | 06-21-2012 |
20120285216 | Modular Rolling Mill - A modular rolling mill has a mill pass line along which products roll. The rolling mill comprises first gear units arranged along a first line parallel to the mill pass line. Each first gear unit is driven individually by a motor and has a pair of mechanically interconnected first shafts. Second gear units are arranged along a second line between and parallel to the first line and the mill pass line. Each second gear unit has a pair of mechanically interconnected second shafts. Rolling units are arranged along the mill pass line, which are driven by an input shaft and has a pair of roll shafts carrying work rolls. First couplings connect the first shafts of each first gear unit to second shafts of two successive gear units, and second couplings releasable connect the second shafts of the second gear units to the input shafts of two successive rolling units. | 11-15-2012 |
