Definitions

  • the invention relates to a method for producing hot-rolled steel strip from pre-material that has already been strip-shaped, in which parts of the same length are first separated from the cast strand that has solidified after casting, in which these parts are then passed one after the other into a furnace and stored therein and brought to the rolling temperature and held, and in which finally the cast strand sections are successively introduced at a rolling temperature for rolling into a rolling mill.
  • the invention also relates to a device for carrying out this method, which consists of a continuous casting system for the continuous casting of a strip-shaped cast strand, of a cross-section device for dividing the solidified cast strand into cast strand sections and a temperature compensation and storage furnace for the cast strand sections and a downstream one Rolling mills exist, the storage furnace containing a plurality of storage locations for cast strand sections that can be operated by a transverse transport.
  • the plant for carrying out the method comprises a continuous casting plant for casting the band-shaped cast strand, one of these downstream winding device forming the band-shaped casting strand into a bundle, a cross-cutting device provided between the continuous caster and the winding device, an unwinding device downstream of the winding device for unwinding the cast strand to form a flat band, and in line with this unwinding device the rolling mill for rolling out the unwound cast strand to the hot strip.
  • the aim is to create favorable conditions for an energy-saving production of steel strip from continuous cast material by saving the facilities necessary for reheating slabs in the usual hot rolling of steel strip and also avoiding expensive intermediate transport devices and intermediate storage spaces. This is also intended to avoid the high deformation effort required for rolling out conventional slabs and the high deformation energy required for this.
  • the cast strand sections In the rolling process following the unwinding of the cast strand sections from the collar, the cast strand sections inevitably have a different temperature profile in their longitudinal direction, by means of which the quality of the steel strip produced by the subsequent rolling process can be permanently impaired. Because that is because of the unwinding of the cast strand sections from the federal government closing rolling cycle runs relatively briefly, temperature compensation in the longitudinal direction of the previously processed cast strand section can practically no longer be achieved.
  • the invention aims to provide a method for the production of hot-rolled steel strip of the known type described above and an installation for carrying out this method, with or by which the rolling out of the steel strip can take place using cast strand sections which can be carried out via their have a constant temperature profile over the entire length, resulting in a high-quality end product.
  • this object is achieved according to the invention in that, according to the characterizing part of claim 1 the cast strand sections with elongated length are introduced into the furnace and stored therein until they are rolled, that a large number of cast strand sections are pre-produced and stored until the start of rolling, and that the continuous casting is continued continuously during the rolling operation, and the cast strand sections formed thereby are introduced into the furnace and stored in turn until they are rolled.
  • the process steps indicated advantageously ensure that each cast strand section remains in the furnace for a relatively long period between the end of the casting process and the start of the rolling cycle and, as a result, practically without additional energy being supplied from the solidification temperature of the cast strand to the required one within this period Brought rolling temperature of the cast strand sections and is also held on this. Since between the storage and the beginning of rolling always a larger number of cast strand sections with stretched Length remains in the furnace, a temperature profile that is practically uniform over the entire length is obtained, especially since cast strand sections can still get into the furnace from the continuous casting installation during the rolling operation.
  • the cast strand sections in the furnace are brought from their outlet temperature from the casting machine (about 1150 ° C) to the rolling temperature (about 1050 ° C) and their residence time in the furnace to an integral multiple of the casting time is set for a cast strand section.
  • the rolling cycle for such a casting section should also last for a period of 2.5 minutes.
  • the pure rolling time can then run for about 2.5 minutes, while the subsequent pause time then comprises about 10 minutes.
  • assembly times on the rolling mill are placed in the pause times of the rolling cycles and, where appropriate, the pause times of two rolling cycles are placed directly one behind the other and that cast strand sections formed in the meantime are additionally placed in the furnace introduced and stored in it.
  • Break times of approximately 10 minutes between successive rolling cycles are usually sufficient to carry out the assembly work (roll change) required on the rolling mill. If, however, it turns out that an available pause time is not completely sufficient for the completion of the assembly work, then according to the invention two pause times can advantageously be directly strung together, to which two rolling times can then also be strung together in order to subsequently achieve the normal course of further rolling cycles.
  • a system for carrying out the method explained in detail above is particularly characterized by the features of claim 5, according to which the storage furnace with its transverse transport is set up for receiving cast strand sections in an elongated length.
  • the storage furnace contains a larger number of storage locations for cast strand sections which can be loaded one after the other, which is matched to the difference between their required residence time in the furnace and the casting time for a single cast strand section.
  • the storage furnace has - according to the teaching of claim 8 - at least the ratio 4: 1 four storage locations for cast strand sections.
  • the storage furnace contains buffer storage locations for continuous casting sections in addition to the storage locations, which during continuous operation of the continuous casting system during extended downtimes of the rolling mill between the Rolling times of two successive rolling cycles can additionally be fed with cast strand sections in an extended length.
  • the storage locations are essentially horizontally next to one another in the storage oven, while the buffer storage locations are arranged one above the other in the vertical direction and are positioned laterally of the storage locations.
  • the buffer storage spaces within the storage furnace can be set individually one after the other on the transport level of the cast strand sections and the storage spaces.
  • the cast strand sections produced during the necessary, extended downtimes of the rolling mill with continuous operation of the continuous casting installation can be done with relatively little additional effort and space without impairment of the storage spaces in the storage furnace are recorded and can be rolled out to the steel strip without any problems after the rolling mill has come to a standstill by appropriately increasing the number of successive rolling cycles, in that the successive rolling cycles are then shortened by a corresponding reduction in their break times, with the rolling remaining constant.
  • the number of buffer storage locations is provided at least equal to the number of storage storage locations in the storage furnace.
  • a transfer device for individual cast strand sections is provided between the longitudinal transport for the individual cast strand sections, the transverse transport of the storage storage spaces and the buffer storage spaces, which then comes into operation if cast strand sections have to be taken over from the longitudinal transport into the buffer storage locations or are to be transferred from these to the transverse transport for the storage storage locations.
  • the rolling mill downstream of the storage furnace is designed as a continuous finishing train.
  • This continuous finishing train can be equipped with normal finishing stands as well as with compact finishing stands.
  • the rolling mill downstream of the storage furnace is designed as a reversing stand, in particular as a Steckel rolling mill, with coil reel or reel furnaces on the outlet and inlet side.
  • the system for producing hot-rolled steel strip has a continuous casting machine 1, at the output of which a roller table 2 connects, to which a flame cutting machine 3 is assigned as a cross-cutting device for dividing the casting strand 4.
  • the liquefied material for forming the cast strand 4 is cooled in the sheet guide of the continuous casting machine.
  • the outlet temperature of the cast rod 4 at the end of the sheet guide is still above 1150 ° C.
  • the solidified cast strand 4 runs from the roller table 2 into a storage oven 5 at a temperature of approximately 1150 ° C. and is initially taken up by a roller conveyor adjacent to the roller table 2.
  • the cast strand 4 is divided by the flame cutting machine 3 into cast strand sections 4a of a predetermined length, for example of 50 meters.
  • the cast strand sections 4 retracted into the storage furnace 5 are then moved step by step by means of a transverse transport 6 within the storage furnace 5 and transversely to their longitudinal direction, the transverse transport 6 having a plurality, for example four, of storage spaces adjacent to one another at a distance.
  • the first of these storage locations is located in the storage oven 5 in the axial alignment with the roller table 2, while the last storage location in the axial alignment is provided with a roller table 7 downstream of the storage oven 5.
  • the roller conveyor 7 is assigned a roller conveyor, with the help of which the cast strand section 4a brought to the last storage location by the transverse transport 6 can be brought from the storage oven 5 onto the roller conveyor 7.
  • the continuous casting machine 1 requires a casting time of l2.5 minutes for the formation of a casting strand 4 with a length dimension of 50 meters corresponding to a casting strand section 4a, then it follows that the transverse transport 6 within the storage furnace 5 in each case Intervals of l2.5 minutes have to carry out a transport step and accordingly the passage time of each cast strand section 4a through the storage furnace 5 is approximately 50 minutes before it is transferred to the roller table 7. Shorter throughput times can also be set using idle cycles.
  • the individual cast strand sections 4a are brought to an outlet temperature of approximately 1050.degree. The temperature reduction by approximately 100 ° C. can take place within the storage furnace 5 practically without any external energy supply, the temperature profile in the longitudinal direction of the individual cast strand sections being very uniform.
  • the individual cast strand sections 4a are first passed through a descaling station 8 and then reach a continuous finishing train 9, which comprises, for example, six four-high finishing stands.
  • a cooling section 10 adjoins the continuous finishing train 9 and is effective in the area of a transport roller table 11. From the transport roller table 11, the finished rolled steel strip l2 is fed to a take-up reel l4 via a driving device l3 and is wound by the latter into a coil.
  • the roller conveyor assigned to the last storage location of the transverse transport 6 in the storage oven 5 can be designed as a pendulum roller table, with the help of which this can be done in each case located cast strand section 4a to a limited extent can move back and forth within the storage furnace 5 if necessary.
  • each cast strand section 4a arrives from the storage furnace 5 on the roller table 7 and thus into the continuous finishing train 9 only at intervals of approximately l2.5 minutes, a time of approximately l2.5 minutes is also available for each rolling cycle.
  • the actual rolling time for each cast strand section 4a within the continuous finish however, street 9 is much shorter than the available cycle time.
  • each individual rolling cycle has a pause time of approximately 10 minutes, during which the continuous finishing train 9 and consequently also all of the parts of the plant downstream of it can go out of operation.
  • all normally required assembly and conversion work on the continuous finishing train 9, in particular the roll changes on the individual four-high finishing stands can be carried out within this break time, because these break times correspond to an integral multiple, e.g. four times the required rolling time.
  • the normal pause time between two successive rolling cycles is not sufficient to completely end the assembly and conversion work to be carried out in the area of the plant adjacent to the storage furnace 5, namely in particular on the continuous finishing train 9.
  • the continuous operation of the continuous casting machine 1 must also be interrupted. That is, the cast strand sections 4a produced by the continuous casting machine 1 during the extended downtime of the system parts arranged downstream of the storage furnace 5 must additionally be accommodated in the storage furnace 5 without the operation of the transverse transport 6 having or forming the storage locations being impaired in any way becomes.

  • a special transfer device is provided between the runway arranged in the region of the transverse transport 6 and in extension to the roller table 2 and the buffer storage locations l5 within the storage oven 5.
  • This for example, like the transverse transport 6, can be designed as a walking beam transport device.
  • the walking beam transport device of the transverse transport 6 only needs to be designed in such a way that it effects transport steps in only one transport direction, in the case of the transfer device assigned to the buffer storage locations l5, it is necessary to provide a design with which two transport directions that are opposite to one another are optionally available can be mastered.
  • the number of buffer storage locations l5 in the storage furnace 5 is made at least equal to the number of them select available storage locations.
  • the number of buffer storage locations l5 is selected to be even larger than that of the storage storage locations. This is because there are five buffer storage locations l5 in the case of four storage locations.
  • two cast strand sections 4a and 4b can be made if the pause times are shortened to 3.75 minutes roll out and take over from the buffer storage locations l5 to the storage locations of the transverse transport 6 in the storage furnace 5.
  • FIGS. 4 to 6 differs from that according to FIGS. 1 to 3 basically only in that the storage furnace 5 is assigned a four-high rolling mill l7 operating with a reversing operation instead of a continuously working finishing train 9 with four-high mill stands which works as a Steckel rolling mill with a coil reel or reel furnace l8 on the outlet side and a coil reel or reel furnace l9 on the inlet side.
