Definitions
- the invention relates to a method and a casting and rolling plant for semi-continuous rolling or continuous rolling by casting a metal, in particular a steel strand, which is cross-divided after solidification, if necessary, the casting strand partial lengths are guided into a roller hearth furnace for heating and uniformity to the rolling temperature , and the partial lengths with rolling temperature are introduced for rolling into a rolling mill, the continuous casting being continued without interruption during the rolling operation.
- Such a method is known from EP 0 264 459 B1.
- the partial lengths of the casting strand are stored in the tunnel furnace with transverse transport.
- the partial casting lengths are stored over a period of time which is a multiple, e.g. four times their casting time.
- the method is carried out in such a way that the rolling of each individual casting strand part length is carried out in a time unit which is only a fraction, e.g. corresponds to a fifth of its casting time, and to the effect that the rolling is carried out discontinuously and the rolling process is interrupted with a pause for a period of time which corresponds to the difference between a casting time and a rolling.
- This process is strictly based on continuous casting and is not matched to the rolling process.
- the invention has for its object to tune the semi-continuous rolling and the continuous rolling more closely to the conditions during rolling in order to adapt the rolling process to the continuous casting process.
- the object is achieved according to the invention in that the casting speed is reduced for a roll change in such a way that a sufficient buffer time for a roll change is maintained between the end of the rolling of the previous multiple length and the piercing of a new partial length or multiple length in the rolling mill.
- the semi-endless rolling and the endless rolling are adapted to the conditions of the rolling and a buffer time is created for the inevitable roll change.
- the larger lengths of rolling stock resulting from semi or endless rolling are taken into account in that several coils are produced from a multiple length.
- the buffer time for the roll change can also be influenced by reducing the casting speed depending on the feed speed of the rolling mill and / or the roll change time including the calibration time and / or the buffer length of the roller hearth furnace and / or the final roll thickness after the cross-cutting.
- the buffer length of the roller hearth furnace be matched to at least one roller level.
- the casting speed V c which corresponds to the feed speed V w of the rolling mill, is reduced to the same or greater according to the following formula:
- a further time saving can be achieved by increasing the final rolling thickness and / or the feed speed of the rolling mill between rolling campaigns within a casting sequence after the cross-cutting.
- Another embodiment is that a combination of an adjustment of the casting speed and the final rolling thickness is used to optimize the production output.
- Another buffer time can be achieved by increasing the final rolling thickness by a factor of 2 and reducing the casting speed to a minimum of 30%.
- the method can be used in such a way that, after the cross-cutting, the casting speed is reduced and / or the drawing-in speed of the rolling mill and / or the final rolling thickness are increased, the worn rolls of the rolling mill are changed after the rolling has ended and after this has taken place Roll change the casting speed is increased to the feed speed of the rolling mill.
- the casting and rolling system required for carrying out the process for semi-continuous rolling or continuous rolling of a cast metal or steel strand which can be divided into partial lengths when required in the solidified state and the partial lengths of the continuous strand can be kept warm in a roller hearth furnace and heated to the rolling temperature and comparable and are insertable into a rolling mill, the sequential arrangement of the continuous casting machine, a transverse partial facility, a roller hearth furnace, additional facilities, a rolling mill and at the end of a coiler.
- the casting and rolling system can then be operated according to the method described above, in that between the continuous casting machine and the rolling train a roller hearth furnace with at least one roll level, at the entrance and / or exit of which a cross-section device, subsequently a descaling device, is provided, followed by the rolling train and a separating device, a cooling section and coiler systems are arranged behind the rolling mill.
- One embodiment consists in the fact that, with at least two roller levels, pivotable roller tracks are arranged at the entrance and exit of the roller hearth furnace, each with a bending and / or straightening unit. The strand material can thus be guided precisely into the respective roll level.
- the strand guide can also be designed in such a way that multiple lengths can be introduced 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.
- FIG. 2A shows a partial side view with a casting strand, the casting speed being equal to or less than the rolling speed
- FIG. 2B shows the same view with the transport speed of a casting strand partial length increased to the rolling speed
- 3A shows the continuous casting and rolling at the same casting and rolling speed and with two coiler systems
- FIG. 3B shows the continuous casting and rolling with the two coiler systems
- FIG. 4A shows the situation when the roll is changed and the casting speed is reduced
- FIG. 4B shows the situation after the roll has been changed and increased
- a casting and rolling plant is shown in side view, consisting of a continuous casting machine 1, in which a casting strand 1 a is generated, a roller hearth furnace 2 and a rolling mill 3 with the associated ancillary devices.
- a tundish 4 is fed from a ladle (not shown), to which a continuous casting mold 5, a support roller stand 6 with a bending unit 7 and a straightening machine 8 are arranged.
- a transverse dividing device 10 and behind it (as an alternative in FIG. 5) a pivotable roller conveyor 11 for the entrance 12a of the roller hearth furnace 2.
- a pivotable roller conveyor 13 and a cross-section device 14.
- the basic embodiment in FIG. 1 works without the pivotable roller conveyors 11, 13.
- the rolling mill 3 begins after the cross-cutting device 14 with a descaling device 15. This is followed by the rolling mill 3 with about five to seven roll stands. Downstream of the roll stands, a cooling section 17 and, following this, two coiler systems 18 are provided after a separating device 16.
- the method is used for semi-continuous rolling or continuous rolling by casting liquid metal, in particular liquid steel, into one
- Casting strand 1 a which after solidification in the cross-section device 10 in casting strand partial lengths 20 is conveyed into the roller hearth furnace 2.
- the respective casting strand part length 20 is heated in the roller hearth furnace 2, the temperature is evened out and brought to the rolling temperature for rolling out in the rolling train 3. During this time, the continuous casting continues without interruption.
- the casting speed V c is reduced for a roller change such that a sufficient one between the end of the rolling of a previous multiple length 21 and the piercing of a new partial length 20 or multiple length 21 in the rolling train 3 Buffer time for the roll change is available.
- Multiple coils 22 can be wound from the multiple length 21.
- the casting speed V c is reduced, for example, as a function of the feed speed V w of the rolling train 3 and / or the respective roll change time, including a calibration time and / or the buffer length 23 of the roller hearth furnace 2 and / or the final roll thickness after the cross-cutting.
- the buffer length 23 of the roller hearth furnace 2 can be matched to at least one roller level 24 (cf. FIG. 1).
- the casting speed V c is set equal to or less than the drawing speed V w into the rolling mill 3. As soon as the roller hearth furnace 2 is loaded, the speed V c can be raised again to the feed speed V w , as shown in FIG. 2B.
- Fig. 3A endless rolling is shown.
- the casting strand 1 a is guided and rolled at the casting speed V c , which is equal to the drawing speed V w into the first roll stand, then cooled, wound and cut in the separating device 16.
- the casting strand 1a as shown in FIG. 3B, can be used with a reduced casting Velocity V c are poured and the part of the cast strand 20 separated is rolled and wound at feed speed V w .
- the casting speed V c is reduced equal to or greater according to the following formula: 1
- V w feed speed of the rolling mill (m / min)
- ⁇ t roll change time (min)
- L length of the tunnel furnace (m).
- the roll change is shown in Fig. 4A.
- the casting speed V c according to the above calculation is 6.67 m / min and is accordingly lower than the drawing speed V w .
- the casting speed V c is increased again to the drawing-in speed V v .
- the final rolling thickness and / or the drawing-in speed V w of the rolling train 3 can be increased after the cross-cutting.
- the final roll thickness can be increased by a maximum of 2.5 times.
- Another option is that the final roll thickness is increased by a maximum of a factor of 2 and the casting speed is reduced to a minimum of 30%.
- the casting speed V c is reduced and / or the drawing-in speed V w of the rolling mill 3 and / or the final rolling thickness are increased, after the rolling has ended, the worn rollers 3a of the rolling mill 3 are changed and after the roll change, the casting speed V c is increased to the draw-in speed V w of the rolling train 3.
