Definitions

  • the present invention is related to an improvement in continuous cold rolling apparatus wherein continuous endless rolling is enabled regardless of the relative locations of entry facilities and rolling mills, which relation may vary dependent on the layout of a plant.
  • the present invention has been contrived in order to obviate the above-mentioned defects by providing a direction-changing looper between the entry facilities and rolling mill for changing the direction of the strip.
  • Such an arrangement is useful for connecting the entry facility to the rolling mill when they meet at a right angle or are in parallel to each other.
  • a continuous and endless rolling in any type of layout of the plant is facilitated.
  • FIG. 1 shows a diagram depicting one embodiment of the present invention wherein entry facilities and the rolling mill are placed in parallel to each other;
  • FIG. 2 shows a plan view of the embodiment of FIG.
  • FIG. 3 illustrates another embodiment wherein entry facilities and the rolling mill are placed at right angles to each other.
  • FIG. 4 shows a plan view of the embodiment of FIG. 3.
  • the entry facilities including a looper 17 and the rolling mill are placed in parallel to each other and 1 is a payout reel, 2 a coil loading car, 3 a pinch roll, 3a a looper pinch roll, 4 a shear, 5 a coil loading skid, 6 a welder, 7 a bridle roll, 8 a loop car, 9 a torque motor, 10 a steering roll, 11 a deflector roll, 12 a roll stand for rolling mills, 13 a speed reducer for rolling mills, 14 a flying shear and 15 a tension reel, respectively.
  • the entry looper 17 may be a horizontal looper as shown in drawings, a free hanging looper or a looper tower.
  • the direction of the strip movement ischanged by a second looper (18) provided between the rolling mill and the entry facilities which includes a pay-out reel 1, a welder 6, and the first looper 17 which is used for strip accumulation, as is well known.
  • the direction of the strip movement may be changed by a free-hanging looper 18 as shown in drawings.
  • the strip which has come out of the entry facilities is directed toward the rolling mill by the direction-changing looper l8 and is then continuously rolled.
  • FIGS. 3 and 4 Another embodiment of the present invention is shown in FIGS. 3 and 4, wherein the entry facilities and the rolling mill meet at a right angle to each other.
  • the horizontal strip accumulating looper of the entry facilities is provided on top of the welder in the embodiment of FIGS. 1 and 2, but on the floor adjacent to the welder in the embodiment of FIGS. 3 and 4. Any type of strip accumulating looper may be used in the entry facility to connect the coils with a welder and the position of the entry strip accumulating looper may also be arbitrary.
  • the entry facilities including the pay-out reel, the welder and the strip accumulating looper may be positioned arbitrarily with respect to the rolling equipment, i.e. aligned in a straight line, positioned in parallel, or meet at a right angle, and the direction of the strip is changed freely by the direction-changing looper and fed into the rolling mill so that an improved and effective continuous, endless rolling is facilitated without being limited in any way by the layout of the plant.
  • a free-hanging looper interposed between said entry facilities and said rolling stands and including means for receiving a strip from said entry facilities, means for forming a free hanging loop of said strip and for then changing the direction of said received strip, and means for then feeding said strip to said rolling stands.
  • said freehanging looper includes a bridle roll receiving the metal strip from said entry facilities and for paying out said strip in the direction in which it was received; and a pinch roll angularly oriented with respect to said bridle roll and receiving said strip from a direction different from that in which said bridle roll pays out said strip, and for feeding said strip in said different direction, a free-hanging loop of said strip being formed between said bridle roll and said pinch roll.
  • said freehanging looper includes a bridle roll receiving the metal strip from said entry facilities and for paying out said strip in the direction in which it was received; and a deflector roll receiving said strip from a direction difference from the direction in which said bridle roll pays out said strip, and for feeding said strip in said different direction, a free-hanging loop of said strip being formed between said bridle roll and said deflector roll.
  • a pinch roll spaced from said bridle roll and oriented in a direction in which said strip is fed out from said pinch roll, a free-hanging looper strip being formed between said pinch roll and said further roll.
