Definitions
- the invention relates to a process for continuous Manufacture of steel strip or sheet steel from according to the Continuous sheet casting process with horizontal outlet direction manufactured flat products.
- One of the new technologies in terms of the current requirements for steel production currently being processed concerns the processing stages between the melting of the steel and reeling the steel strip in the form of rolls or “coils” or the stacking of sheets and comprises the casting of thin slabs close to their final dimensions Thickness, which then followed in just a few Stitches or deformation steps to the desired one End product can be processed further.
- This has remarkable improvements in continuous casting technology led, especially in terms of construction the mold and the corresponding immersion spout, as well as improvements in construction of the rolling stands and lines with the aim of in as far as possible a few stitches to achieve the desired deformation.
- Another solution is to separate the Tape in front of a heating oven, in which subsequently the heat treatment (temperature compensation) of the Band made over its entire cross section becomes.
- This can e.g. be a gas heated roller oven, with the irrespective of the casting speed to be taken into account a strip temperature at the furnace outlet 1100 degrees C can be set, so an optimal temperature for the subsequent rolling process.
- the tape is cut to a standard length, for example for a specific coil weight can be at 50 m, for which a corresponding Oven length of approx. 150 m is required if you consider the takes into account the required buffering effect.
- the aim of the present invention is to create a method of the type described above and a corresponding system for carrying out this Process with which steel strip is continuously made from a flat product coming from a continuous caster can be produced without the aforementioned disadvantages to take over.
- the aim is to separate the strand between the casting process and at least the first rolling process be dispensed with, tapping the casting strand in the first mill stand at that speed takes place with which the rolling stock the arc section of the continuous caster leaves.
- the process should therefore be "in line” done with virtually unlimited flexibility so that it becomes possible to use coils of any type Manufacture weight and any length or sheet, without changing the dimensional parameters of the system, since the cutting off of the rolled strip is at least after the first rolling process or after execution all operations immediately before the reel or Stacking device is made.
- the object is achieved by a method according to claim 1.
- An essential aspect of the present invention is the inductive reheating of the flat product after descaling to temperatures of approx. 1100 degrees C. with the best possible temperature compensation, because such a Countercooling of the belt counteracted in a favorable manner can be.
- one or more levels of inductive Intermediate heating of the flat product between the above Deformation stages to be provided Through this Intermediate heating also becomes too strong Cooling of the rolling stock counteracted, so that always the necessary rolling temperatures are set in this way can be that in the last stage of deformation Temperatures not below the limit of 860 degrees Celsius sink.
- the run-up strand can be run through the roll stands be separated with that facility, those for dividing the rolled strips are available anyway is, or it can by another separation device separated behind the first stage of deformation become.
- the separating device can be behind the first deformation device be arranged and between the first deformation device and the further deformation device can be a device for opening and closing Uncoiling of the flat product may be provided, which precedes the separating device.
- the device for winding and unwinding the Flat product behind the device for inductive Heating up and in front of the further shaping device arranged.
- this system is either a separation device for the rolled strip and downstream of at least one reel for reeling the tape or a separation device for the rolled strip, a cooling device, a straightening machine and a stacking device for the separated sheets.
- system additionally at least one device for inductive heating for intermediate heating between the other rolling stands.
- each of these devices is separate controllable heating levels.
- the system also with adjustment devices of the flow cross section between the roles of first deformation device and the other rolling stands equipped to the flow of the head to enable the starting strand of the casting strand to sit and immediately after its passage the Cross sections back to the usual throughput values attributed.
- Successive control devices of the individual heating levels of the ovens immediately after passing through the start-up line, the Disconnect device for separating the start-up line is the one that is also used to cut off the rolled strip is used, namely that at the end portion of the Separating device in the system.
- the Disconnect device for separating the start-up line used which is behind the first stage of deformation located.
- the invention is roughly schematic System shown, based on which the corresponding Procedure is described.
- Starting from a continuous casting mold, marked with 1 in the drawing is the flat product 2. That in conventional Support rollers guided and transported flat product 2 goes from the initial vertical direction over the arc path formed by the support rollers in the horizontal position. After solidification, namely in the end area of the arc, that goes through Flat product according to the invention a first stage of deformation 3, for example, to a thickness of is brought to a maximum of 25 mm.
- Deformation stage 3 can consist of one or more rolling devices, preferably in quarto order.
- a furnace 5 is subsequently provided for temperature compensation, the one with an inductive heating device Is provided.
- this oven 5 is done at the same time a temperature compensation over the entire Cross section of the flat product 2, so that this the first frame 6 of the further deformation device reached with sufficient rolling temperature.
- the tapping speed is too slow, this is appropriate the one driven when exiting the arc Speed to a significant drop the temperature so that in the second Roll stand 7 of the further deformation device a insufficient deformation temperature, so it can if necessary, another intermediate heating in the form of a second induction furnace 8 between the roll stands 6 and 7 can be provided, which can be shorter than the furnace 5.
- the second induction furnace is only required if the furnace 5 is insufficient, around during the deformation along the whole the three rolling stands 6, 7 and 9 existing others Deformation device the corresponding temperature gradient adjust, in such a way that when tapping in the last mill stand 9 the temperature inside the order of magnitude sufficient for good deformation lies.
- band 2 ' 2 the desired thickness.
- the process ends either by reeling the rolled strip 2 'on the reel 11 and the severing at 10 after reaching the desired fret or "Coil" weight or with the severing of the tape 2 ' in the desired lengths and then stacked from a stacking device 14, which is schematic in FIG. 2 is drawn.
- the device for severing the tape 10 at the beginning of the work cycle also to separate the Start-up string (not shown here) used be turned off after going through the Induction furnace 5 and the disassembled rollers the deformation device 6, 7 and 9, as well as the possibly provided and also switched off Intermediate heating device 8 is separated.
- Appropriate adjustment devices are provided with those immediately after passing through the starting line the rollers on those needed for the deformation normal roll gap are started again.
- the heating devices 5 continue to set preferably from mutually independent zones together so that, starting from the state of being turned off Oven the one through which the approach piece passes Oven zones switched on one by one to warm up become.
- Figure 2 shows the schematic representation of the individual sections for a system according to FIG. 1 (using the same names) the temperature curve of flat product 2 until exit of the band 2 'from the last rolling stand. Below a table is shown from the graph that in accordance with certain sections of the plant and the corresponding sections of the Band the respective speed at the appropriate Thickness can be seen. The recorded values were experimentally with a tape of 1000 mm width and 25 mm thick. Of course, at different dimensions and speeds another Temperature curve to be recorded.
- the partially rolled strip falls in one intermediate inductive furnace 8 of 1020 degrees C. heated to 1120 degrees C.
- the first rolling stand is the next Deforming device previous heating and if necessary, between the first and further rolling stands intermediate heating to be set so that heating the flat product or the rolled strip after the first stitch to a temperature of approx. 1100 degrees C takes place and the temperature level like this is held that the final rolling temperature in the last Roll stand does not fall below the limit of 860 degrees C.
- the an additional induction furnace 8 can be installed.
- the finished bundle will at 11, e.g. on a downcoiler.
