Definitions

  • the present invention relates to an industrial installation and method relating to the technical field of metal strip rolling mills, in particular of the tandem type with continuous winding station, having at the end of rolling an inspection table of the rolled product and being wound .
  • a problem that arises is to detect as soon as possible in the manufacturing process the defects that may be unacceptable for the rolled strip, such as surface defects, geometry, thickness, flatness, etc.
  • a separate inspection of the line is not possible because it is disadvantageous from the point of view of the loss of time and therefore from the economic point of view.
  • the document JP 2000 254725 discloses a cold rolling plant comprising, mounted in this order on the line, a cold rolling mill, a movable shear which cuts the continuous steel strip produced by the rolling mill, a double mandrel tension winding apparatus, Carousel roller type, which rolls the steel strip continuously.
  • the carousel winder is positioned downstream and below the cold rolling line and a surface inspection apparatus which inspects the surface of the steel strip, is located downstream on an extension of the line of pass that passes over the carousel coiler.
  • the installation is provided with switching means for directing the band towards the reel to carousel or alternatively to the surface inspection apparatus, positioned outside the moving shear.
  • the document EP 1 581 355 discloses a method for successively rolling and winding a metal strip, in particular a steel strip, on a rotatable and rotatable winding mandrel, wherein the metal strip is inspected in longitudinal portions by compared to rolling anomalies.
  • the strip samples are produced by a drum shear located after the last rolling stand, guided and stopped "in line” inside the rolling line above a winding station located below the rolling line. rolling line, on an inspection table, for a free visual inspection.
  • the winding station is therefore located under the plane of the inspection table, the latter being arranged "in line" with the rolling line.
  • the steel strip emerging from the last rolling stand can be guided so that a baffle unit, arranged at the entrance of the winding station, can deflect the metal strip towards a winding mandrel.
  • the inspection table is provided with gripping means that allow to return the tape samples to also inspect the other side.
  • the tape samples are routed to a shear which cuts them into pieces before gravity collection in a bin or waste car.
  • the present invention aims to enable the realization of a quick and inexpensive inspection of rolled metal strips in a rolling plant operating continuously, including the winding station.
  • the invention also aims to achieve a simple and reliable installation to perform this inspection.
  • the invention also aims to provide an installation that can fit into an existing line, where there is very little room in length.
  • a second aspect of the present invention relates to a winding and on-line inspection facility of a continuously rolled metal strip, comprising, downstream of the last rolling stand, a first shear, a winding station on at least one mandrel and inspection table for detecting defects on at least one side of a sample of the strip, characterized in that the inspection table is part of a separate inspection line, parallel to the rolling-winding line, and in that the installation further comprises an insertion table, situated initially between the shear and the winding station in the rolling line.
  • the introduction table for transporting to the inspection table a band sample obtained at the tail end by means of said shear by two successive sectioning of the strip to obtain a determined sample length corresponding at least partially to the length of the introduction table.
  • the winding station is a carousel station.
  • the installation comprises, at the level of the inspection table, gripping means grippers that return the sample to inspect the other side.
  • the inspection table is extended by an evacuation table, at the end of which is a second shear to cut the sample into pieces, as well as a waste container. or similar.
  • the figure 1 is a plan view of the carousel winding station coupled with an inspection table according to a preferred embodiment of the present invention.
  • the figure 2 represents two longitudinal sectional views, AA and BB respectively, of the carousel winding station according to the figure 1 .
  • a preferred embodiment of the installation according to the invention is represented on the figures 1 and 2 .
  • the strip of the so-called "No. 1" coil 1 (on the mandrel of the right and upper 10) is cut a first time at the first shear 4, which generates a band tail of the coil 1 which will be wound.
  • the belt is still moving Y meters on the infeed table 6 before being cut again by the shears 4, in order to obtain a sample that covers all or part of the length of the infeed table 6.
  • the conveyor 15 moves the infeed table 6 with the sample parallel to itself and to the rolling-winding line, until it is positioned along the inspection line, facing each other. from the inspection table 8. At this point, the tape is stopped completely. During this time, the coil 1 is wound up completely.
  • the nose-mandrel support 9, supporting the right mandrel 10, is evacuated.
  • the "No. 1" coil 1 is then removed from the right mandrel 10 and discharged with discharge means 16.
  • the cut sample advances on the inspection table 8 and the sample is inspected on a first face.
  • the ends of the sample are pinched by pinching means 8 ', 8 "and the sample is returned (not shown)
  • the other side of the sample is inspected
  • the ends of the sample are" peeled off "
  • the sample advances on the evacuation table 12, at the end of which a shear 13 cut the sample into pieces, which will then be directed to a bin or waste wagon 14
  • the next tape head advances on the introduction table 6 to the winding carrousel 3 and the so-called "No. 2" coil 2 begins to be wound on the mandrel left and lower 20. Once a few turns are wound , the belt reel 5 used to initiate the winding of the web is evacuated. The winding speed increases.
  • the nose-mandrel support 11, supporting the left mandrel 20, is evacuated and the winding continued. During this one, the carousel 3 rotates 180 ° in the direction of clockwise.
  • the nose-mandrel support 9 moves into position to support the new mandrel of the right and upper 10.
  • the winding of the new coil "No. 2" 1 'therefore continues on the new mandrel right and top 10.
  • the nose-mandrel support 11 moves into position to support the new left and lower mandrel 20.
  • the belt winder 5 used for priming the winding of the band is put in the operating position.
  • the running speed of the web and the speed of rotation of the right and upper mandrel 10 are decreased.
  • the strip of the "No. 2" coil is first cut with the shear 4, which generates a tape tail of the coil 1 'which will be wound.
  • the tape is further advanced Y meters on the introduction table 6 before being cut again by the shears 4, to obtain a sample that covers the entire length of the introduction table 6.
  • the inspection is done then as above.
  • the winding of the "No. 2" spool is completed and the spool evacuated. Once, the roll-winding return line introduction table, a "No. 3" coil 2 'will be able to be wound on the mandrel left and lower 10. Once a few turns are wound, the winder belt 5 is evacuated. The winding speed increases and so on.
