Definitions

  • the invention relates to a method and a casting rolling mill for semi-endless or continuous rolling by casting a metal, in particular a Stahlfstrangs which is transversely divided if necessary after solidification, the G manstrang part lengths are guided in a roller hearth furnace for heating and uniform to rolling temperature, and the part-length rolling temperature for rolling in a rolling mill are introduced, wherein the continuous casting is continued during the rolling operation without interruption.
  • a metal in particular a Stahlfstrangs which is transversely divided if necessary after solidification
  • Such a method is known from EP 0 264 459 B1.
  • the G manstrang partial lengths are stored in the tunnel furnace under cross-transport.
  • the G manstrang part lengths are stored over a period corresponding to a multiple, eg four times, their casting time.
  • the method is practiced such that the rolling of each casting strand part length is carried out in a unit of time, which corresponds to only a fraction, eg one-fifth of its casting time, and to the effect that the rolling carried discontinuous and thereby the rolling process in each case over a tent area , which corresponds to the difference between a casting time and a rolling, is interrupted with a pause time.
  • This method is strictly based on continuous casting and is not adapted to the rolling process.
  • European patent application EP 0 853 987 A2 discloses a system for producing a strip, a pre-strip or a slab.
  • the disclosed there invention is based on the object to create a system, which enables high-quality production of the thinnest possible bands, with a very high operational flexibility is given.
  • the continuous casting should be able to continue in the case of a fault at a downstream of the continuous mold deformation stage.
  • US Pat. No. 5,396,695 discloses a method and a device according to the preambles of claims 1 and 9, respectively, for controlling a period of time between the continuous casting of metal strands and their entry into a rolling stand.
  • the invention disclosed there is based on the finding that it takes longer to cast a thicker slab than a thinner slab of the same length. It can therefore be controlled by adjusting or changing the cross section of the cast strand, the speed at which the cast strand emerges between pinch rollers, at the same casting rate. In particular, it is in this way, i. by increasing the cross-section of the cast strand, it is possible to gain time for a roll change at the same flow rate.
  • the object of the invention is to provide an alternative method and an alternative device, in which it is also possible to set time, e.g. to win for a roll change within a rolling mill.
  • This object is achieved according to the method claimed in claim 1, characterized in that between rolling campaigns within a casting sequence after the cross-cutting the final rolling thickness and / or the drawing speed of the rolling mill is increased.
  • the semi-endless rolling and the endless rolling are adjusted to the conditions of rolling, and a buffer time for the inevitable roll change is provided.
  • the larger rolling stock lengths resulting from the semi- or continuous rolling are taken into account in that several coils are produced from one multiple length.
  • the buffer time for the roll change can still be influenced by reducing the casting speed as a function of the drawing speed of the rolling train and / or the roll change time, including the calibration time and / or the buffer length of the roller hearth furnace and / or the final rolling thickness after the transverse cutting.
  • the buffer length of the roller hearth furnace is tuned to at least one roller level.
  • An embodiment is further that a combination of an adaptation of the casting speed and the final rolling thickness is used to optimize the production capacity.
  • Another buffering time can be achieved by maximizing the final rolling thickness by a factor of 2 and lowering the casting speed to a minimum of 30%.
  • the method can be applied according to a practical example such that after the cross-cutting the casting speed is reduced and / or the feed speed of the rolling train and / or the final roll thickness are increased, after the completion of rolling the worn rolls of the rolling train are changed and after the roll change the Casting speed is increased to the feed speed of the rolling mill.
  • the strand guide can also be designed so that multiple lengths can be inserted at a single height level from the outlet of the continuous casting machine through the roller conveyor of the roller hearth furnace into the rolling mill.
  • a casting rolling mill is shown in side view, consisting of a continuous casting machine 1, in which a cast strand 1a is produced, a roller hearth furnace 2 and a rolling mill 3 with the associated ancillary equipment.
  • a distributor vessel 4 is fed from a ladle (not shown) to which a continuous casting mold 5, a support roll stand 6 with a bending unit 7 and a straightening machine 8 are arranged downstream.
  • a cross-cutting device 10 At the output 9 is a cross-cutting device 10 and behind this (as an alternative in Fig. 5) a pivotable roller conveyor 11 for the input 12a of the roller hearth furnace 2 is arranged.
  • a pivotable roller conveyor 13 At its output 12b are again a pivotable roller conveyor 13 and a cross-cutting device 14.
  • the basic embodiment in Fig. 1 operates without the pivotable roller conveyors 11, 13th
  • the rolling train 3 begins after the cross-cutting device 14 with a descaling device 15. Then follows the rolling mill 3 with about five to seven rolling stands. Behind the rolling stands, a cooling section 17 and this following two coiler 18 are provided after a separator 16.
  • the method is used for semi-continuous rolling or continuous rolling by casting of liquid metal, in particular of liquid steel, to form a cast strand 1 a, which after solidification in the cross-cutting device 10 in G confusestrang part lengths 20 is transported in the roller hearth furnace 2.
  • the respective G fauxstrang part length 20 is heated in the roller hearth furnace 2, evened out in temperature and brought to rolling temperature for rolling in the rolling mill 3. During this time, the continuous casting continues without interruption.
  • the casting speed V c is lowered for a roll change such that between the end of rolling a previous multiple length 21 and the piercing of a new part length 20 or multiple length 21 in the rolling train 3 sufficient buffer time for the roll change is available. From the multiple length 21 more coils 22 can be wound.
  • the casting speed V c for example, depending on the feed speed V w of the rolling train 3 and / or the respective roller change time including a calibration time and / or the buffer length 23 of the roller hearth furnace 2 and / or the final rolling thickness reduced after the cutting.
  • the buffer length 23 of the roller hearth furnace 2 can be matched to at least one roller plane 24 (see Fig. 1).
  • the casting speed V c is set equal to or less than the drawing speed V w in the rolling mill 3. As shown in FIG. Once the roller hearth furnace 2 is charged, the speed V c can be raised again to the pull-in speed V w , as shown in FIG. 2B.
  • Fig. 3A the endless rolling is shown.
  • the casting strand 1a is guided and rolled at a casting speed V c equal to the drawing speed V w in the first rolling stand, then cooled, wound and cut in the separating device 16.
  • the cast strand 1a can, as shown in Fig. 3B, with reduced casting speed V c are cast and the separated G manstrang part length 20 is rolled at the pull speed V w and wound.
  • the roll change is shown in Fig. 4A.
  • the casting speed V c is 6.67 m / min according to the above calculation and is accordingly lower than the pull-in speed V w .
  • Fig. 4B the casting speed V c is increased again to the pull-in speed V w .
  • the final rolling thickness and / or the drawing speed V w of the rolling train 3 can be increased after the transverse cutting.
  • the final rolling thickness can be increased by a maximum of 2.5 times.
  • Another option is to maximize the finish roll thickness by a factor of 2 and lower the casting speed to a minimum of 30%.
  • the casting speed V c is reduced, and / or the drawing speed V w of the rolling mill 3 and / or the final roll thickness are increased, after the completion of rolling the worn rolls 3a of the rolling mill 3 are changed and after the roll change, the casting speed V c is increased to the drawing speed V w of the rolling train 3.
