Definitions

  • This invention relates to a process for coiler drum alternation in incessant hot rolling of steel strip and to an apparatus therefor.
  • incessant hot rolling herein is meant a system in which preceding ones and succeeding ones of rough rolled slabs are joined together one after another by a flying welder on the entry side of a finishing hot rolling mill, and the joined slabs are subjected continually to finish hot rolling to produce a steel strip.
  • the traveling speed of the steel strip has been controlled to or below a predetermined value until the leading end of the strip starts being wrapped around the mandrel of the coiler, so as to prevent the leading end portion from being lifted while traveling.
  • the batch rolling system has the drawback of varied rolling speeds and low rolling efficiency.
  • the batch rolling system involves waste of time in, for example, pepara- tory operations between the rolling of a preceding rolling stock and the rolling of the following rolling stock, leading to low efficiency in using the equipment.
  • the finish rolled products are liable to have poor shape at the head and tail ends thereof, resulting in a low production efficiency, and so on.
  • incessant hot rolling is adopted.
  • the steel strip obtained by continual rolling of joined slabs is cut up by a flying shear into lengths of strip corresponding to the initial slabs, followed by coiling by coilers. It is necessary in this case to change over the path of the steel strip so that the leading ends of the cut lengths of strip are guided to be taken up on the respective coiler drums.
  • Techniques for such coiler drum ternation are disclosed in Japanese Patent Application Laid-Open (KOKAI) No. 61-014003 (1986) (Process for Down-Coiler Alternation in Inceimpuls Hot Rolling) and Japanese Patent Application Laid-Open (KOKAI) No. 61-119326 (1986) (Gate Device for RollingLine Alternation).
  • a deflector disposed on the entry side of coiler rolls is moved up and down to achieve alternation of coilers.
  • the up-down motion of the deflector may flaw the steel strip.
  • the deflector is provided with auxiliary rollers. Since the auxiliary rollers are to be arranged in a limited space, however, the rollers should be small in diameter and, due to the small roller diameter, a slight deviation in the position of contact of the roller with the steel strip can render the strip guiding direction unstable, making it impossible to coil the strip.
  • each coiler is provided with a main and an auxiliary set of pinch rolls, which are operated to achieve coiler drum alternation. This technique requires a complicated mechanism.
  • this invention makes an improvement on the alternation of coiler drums for a traveling steel strip in incessant hot rolling, by adopting the following process.
  • the process for coiler drum alternation in incessant hot rolling comprises the steps of oscillating upper and lower tillable pinch rolls disposed on the exit side of a shear, thereby changing the direction of the steel strip so that a leading end formed upon cutting the strip will be directed toward the coiler drum to be used next, and cutting the steel strip.
  • Figure 5 illustrates the entire steps carried out in a hot rolling line.
  • a steel slab 90 is rough rolled by hot roughing mills 50, to become a sheet bar 95.
  • the sheet bar 95 is finish rolled by hot finishing stands 60 into an elongate steel strip 100.
  • the sheet bars 50 are finish rolled one by one, and the resultant steel strips are coiled by coilers 30 one by one (each strip being coiled on one of coiler drums). After one steel strip is taken up on one coiler drum, in the conventional batch rolling system, there is sufficient time for such a preparatory operation as to enable the next steel strip to be coiled on another coiler drum.
  • a welder 70 for joining the sheet bars 95 is provided between the roughing mills 50 and the finishing stands 60, so as to joint the leading end of the succeeding sheet bar to the tail end of the preceding sheet bar. Therefore, the hot finishing stands 60 performs continual rolling of a multiplicity of sheet bars 95 joined together. Since the joined body of sheet bars 95 finish rolled continually in this manner has discontinuity only at the foremost and backmost ends, it is possible to carry out high-speed finish rolling, without any complicated modification of rolling speed.
  • FIG. 4 shows an apparatus according to the prior art, in which pinch rolls 40, 42 can be moved farther apart, and a deflector 44 capable of being moved up and down is provided on the entry side of coiler drums 30a, 30b so as to change the traveling direction of the steel strip 100.
  • the deflector 44 is provided with auxiliary rollers 48 small in diameter. In this conventional apparatus, a slight deviation in the position of contact of the strip 100 with the roller 48 can render the strip guiding direction unstable, making it impossible to coil the strip.
  • Figure 1 is an illustration of the apparatus for coiler drum alternation according to this invention.
  • rough-rolled sheet bars are jointed end to end at a position on the entry side of the finishing stands, the jointed sheet bars are continually hot rolled in the finishing stands, the resultant steel strip is cut up on the entry side of coilers, and the cut lengths of strip are successively coiled, in an alternating manner, on a plurality of coilers arranged in series.
  • upper and lower pinch rolls 10 and 12 are placed in a housing 14.
  • the housing 14 is so designed as to be tilted by a hydraulic cylinder 16.
  • the housing 14 is tilted by the hydraulic cylinder 16 so that the center line 22 passing through the centers of the upper and lower pinch rolls 10, 12 is tilted as indicated by 22a, and a deflector 18 is directed to the side of the coiler 30, whereby the strip 100 is coiled.
  • the housing 14 is returned into the solid-line position in Figure 1, and the deflector 18 into the position for directing downstream.
  • Figure 2 shows the changeover from a coiler 30b on the downstream side to a coiler 30a on the upstream side.
  • a housing 14 on the upstream side is tilted so that the center line passing through the centers of the upper and lower pinch rolls 10a, 12a is tilted, the upstream-side coiler 30a is set ready for coiling, and the steel strip 100 is cut by the shear 80.
  • the upper and lower pinch rolls 10b, 12b of the downstream-side coiler 30b may be in the non- tilted condition. It is thereby possible to maintain a tail end portion of the steel strip 100b securely by the pinch rolls 10b, 12b until the coiling of the strip 100b is finished, and to obtain a better coil form.
  • Figure 3 shows a changeover from the coiler 30a on the upstream side to the coiler 30b on the downstream side.
  • the housing 14b on the downstream side is tilted so that the center line passing through the centers of the upper and lower pinch rolls 10b, 12b of the downstream-side coiler 14b is tilted, and the downstream-side coiler 30b is set ready for coiling.
  • the center line passing through the centers of the upper and lower pinch rolls 10a, 12a of the upstream-side coiler 30a is kept untilted.
  • the steel strip 100 is cut by the shear while the upper pinch roll 10a of the upstream-side coiler 30a is thus prevented from exerting a downward bending force on the succeeding portion of strip.
  • the succeeding portion of strip is moved straight ahead to be caught by the pinch rolls 10b, 12b on the downstream side, and is wrapped around the downstream-side coiler 30b.
