  • Patent number: 9937632
    Abstract: A trim shear is adapted to trim the front and tail ends of a hot rolled product exiting from a rolling mill along a mill pass line and travelling at either high or low speeds, depending on the size of the product being rolled. The trim shear comprises a trim station having a high speed a set of trim knives configured and arranged to trim the front and tail ends of high speed products, and a different low speed set of trim knives disposed laterally from the high speed set of trim knives and configured and arranged to trim the front and tail ends of low speed products; and the trim station is transversely shifted with respect to the mill pass line to alternatively locate either one or the other of the sets of trim knives in an active position on the mill pass line.

  • Patent number: 8997540
    Abstract: A method is described in which a length of hot rolled product is decelerated in the course of being passed through the rotating curved guide of a coiler. The product exits the coiler at a reduced velocity and is delivered to and progressively accumulated on a cylindrical drum as a helical formation of rings. The drum is rotated to continuously unwind the accumulating product at the reduced velocity. The tail end of the product is retained in the coiler until substantially all of the rings previously deposited on the drum have been unwound.

  • Publication number: 20150078688
    Abstract: A bearing arrangement comprises first and second axially spaced oil film bearings rotatably supporting a rolling mill roll shaft. An annular pressure plate is carried by and fixed relative to the roll shaft for rotation therewith. Third and fourth oil film bearings act on opposite sides of the pressure plate to axially fix the roll shaft.

  • Publication number: 20130074567
    Abstract: A rolling mill rotating entry system (RES) with at least one front end-driven drum that indexes alignment of the RES guide path and drum with the bar stock transfer guide path. The front end drive system is offset from the bar stock transfer path, so that the bar stock has sufficient clearance to enter the guide path. The front end drive system facilitates desired indexed alignment of the RES guide path and the bar stock transfer path without the need for front end braking or damping systems that are customarily used with rear driven drums in known RES systems. Other RES embodiments include a rear drive system that drives the drum in tandem with the front drive system.
