Definitions

  • the invention relates to a production system for the production of hot-rolled flat products, consisting of a multi-stand rolling mill, an outfeed roller table with devices for cooling the hot strip and with downstream winding machines for winding the strip.
  • Rolling plants for the production of hot-rolled strips are generally designed and operated today in such a way that the forming in the individual stands is austenitic, which means that it is ensured that the rolling temperatures in the individual stands are above the GOS line of the iron-carbon diagram. Only after the last rolling pass, which should be as close as possible to the GOS line to achieve a fine-grained final structure, does cooling to the coiling temperature take place with structural change in the cooling section or in the wound bundle.
  • the final rolling temperature for rolling according to the process described above i.e. the temperature in the last mill stand of the rolling mill, is around 840 to 920 ° C, depending on the level of carbon content.
  • the final rolling temperature is maintained by changing the final rolling speed, with which the natural cooling of the strip in the rolling mill and the heat input can be controlled by the drive power of the roll stands.
  • This method can be used without problems for strip thicknesses above a minimum strip thickness which, depending on the type of road, is of the order of 1.3 mm. Will this strip thickness below the required rolling speed with values above 12 m per second at the strip head reaches a height that can no longer be controlled in the free run on the roller table behind the rolling mill.
  • a preferred method provides for preliminary rolling in the austenitic range down to an intermediate thickness of 2 to 8 mm and finish rolling in the ferritic range for minimum final thicknesses below 1.3 mm.
  • the rolling stock must be cooled from the finish rolling temperature in the austenitic range to the rolling temperature in the ferritic range. This means cooling from the temperature range of 840 to 920 ° C to the temperature range of 600 to 780 ° C.
  • the final rolling temperature after the second deformation stage is also in the range from 600 to 780 ° C and thus in a range at which recrystallization of the structure in the wound bundle occurs after reeling.
  • a structure is created which enables the product to be used without further cold forming or heat treatment.
  • An essential prerequisite for a good result is compliance with a minimum cooling time for cooling from the austenitic area to the ferritic area. This minimum cooling time must be observed so that austenite can be converted to ferrite to a sufficient extent. This lies depending on the selected temperature and alloy composition for entry into the first ferritic transformation in the range of a few seconds to a few minutes.
  • the object of the invention is to provide a production plant for the rolling of hot strip, with which the aforementioned disadvantages and problems are eliminated and, with the desired limitation of the outlet speed, a selectable part of the reduction of the strip in the ferritic range takes place.
  • At least the first stand of the rolling mill is designed as a reversing stand, to which at least one reel furnace is arranged upstream and downstream, a controllable cooling device being provided between the upstream reel stand and the following reversing stand.
  • a production plant constructed in this way can be operated like conventional plants in the austenitic area.
  • the rolling stock supplied by a roughing mill or thin slab casting machine which usually has a thickness of 50-100 mm, is tempered in an oven to approx. 1100 ° C. and in that from one or more
  • the existing reversing mill (Steckel mill) was rolled by placing one or more stands and wound up in the Steckel or reel furnace that followed the Steckel mill. After reversing the Steckel line, the strip is pulled off the Steckel furnace and rolled down to about 5 to 15 mm in thickness in one or more stands of the Steckel line and then wound up in the Steckel furnace on the input side.
  • the temperature of the belt in this area is still above 850 ° C. Now the strip is unwound from the input-side Steckel furnace and rolled down to a thickness of approx. 1 mm in the Steckel stands and the rest of the rolling mill and wound up by the winding machine.
  • a heating device can be provided between the Steckel mill and the rest of the rolling mill to prevent excessive cooling of the strip.
  • a cooling device can also be provided before the winding of the rolled strip in the input-side Steckel furnace, by means of which the approximately 5 to 15 mm thick strip is cooled to temperatures below 850 ° C. After ferritic transformation, the strip can be rolled down into a strip with a thickness of approx. 1 mm in the Steckel mill and the rest of the rolling mill.
  • the run-out roller table is provided in such a way that the continuously cast strip can be placed on it, preferably without having been rolled in the reversing line. After reversing, the strip is rolled down to approx. 5 to 15 mm in the reversing line, and here too, before winding onto the input-side reel furnace, a decision is made whether to switch the cooling device on or off in the subsequent rolling process in the ferritic or austenitic range should be rolled.
  • one of the reel furnaces can be set to temperatures that are necessary for rolling in the austenitic range, while the second reel furnace can be set to temperatures that for a Rollers in the ferritic range are required.
  • Figure 1 shows a continuous caster 1, which is a pair of scissors 2, a furnace 3, a pair of scissors 4, which is only intended for emergency cuts and a descaling device 5.
  • the Steckel or reel furnace 6 can be seen, which is followed by a cooling device which can be controlled as required and by means of which the strip can be cooled, if necessary, into the ferritic region.
  • two reversing stands 8, 9, a further descaling device which can be switched on as required, and an outlet-side plug-in or reel furnace 11 are shown.
  • the continuously cast pre-strip is rolled down in the reversing stand 8, 9 to a thickness of approximately 5 to 15 mm and wound up in the reel furnace 6.
  • the strip can continue to have austenitic temperatures or, after cooling in the cooling device 7, its temperature can only be in the ferritic range.
  • the reversing mill is followed by a heating device 12, preferably an induction furnace, which, if necessary, adjusts the strip to the temperature in the austenitic or ferritic range necessary for the rest of the rolling mill.
  • the heating device 12 is followed by a further pair of scissors 13, a descaling device 14, the rolling mill 15, a winding machine 16, a cooling section 17 and a further winding machine 18.
  • the heating device 12 is omitted and the reel furnace 11 is placed at the end of a reversing line.
  • the reel furnace 6 is followed by a cooling and / or descaling device 19, which is followed by the reversing line 20.
  • a further cooling and / or descaling device 21 is provided, which is followed by the reel furnace 11.
  • Figure 3 shows a similar production facility as in Figure 2.
  • the reel furnace 6 which is followed by the cooling and / or descaling device 19, the reversing line 20 ', the descaling device 14, the reversing line 20''and a roller table 22.
  • FIGS. 2 and 3 The remaining devices shown in FIGS. 2 and 3 provided at the inlet and outlet of the production plant correspond to those according to FIG. 1.
