Definitions

  • the invention relates to a method for producing hot-rolled steel strip from pre-material which has already been strip-shaped, in which parts of the same length are first separated from the cast strand which has solidified after casting, then these parts are successively transferred to a furnace with a stretched length and stored in the furnace and at the rolling temperature are brought and held, in which a larger number of cast strand sections are pre-produced and stored until the start of rolling and individual cast strand sections are successively introduced at a rolling temperature into a rolling mill for rolling, and in which the continuous casting is continuously continued even during the rolling operation and the cast strand sections thus formed are introduced into the furnace for storage until they are rolled.
  • the invention also relates to a plant for carrying out this method, which consists of a continuous casting plant for the continuous casting of a band-shaped cast strand, of a cross-section device for dividing the solidified cast strand into cast strand sections and of a temperature compensation and storage furnace with transverse transport for receiving the cast strand.
  • a plant for carrying out this method which consists of a continuous casting plant for the continuous casting of a band-shaped cast strand, of a cross-section device for dividing the solidified cast strand into cast strand sections and of a temperature compensation and storage furnace with transverse transport for receiving the cast strand.
  • sections of elongated length which contains a plurality of storage locations for cast strand sections which can be operated by the transverse transport.
  • a certain number of cast strand sections can be deposited in the other half of the storage furnace by moving them from the center of the furnace to a transverse transport on the other side of the furnace. After the interruption has ended, the additionally stored continuous casting sections can then be gradually returned to the normal material flow to the rolling mill.
  • the invention aims to provide a method for producing hot-rolled steel strip of the known type described above and a system for carrying out this method, with or by which the rolling out of the steel strip can take place using cast strand sections, which not only Have a constant temperature profile over their entire length, resulting in a high-quality end product. Rather, it should also be achieved that the cast strand sections continuously produced by the continuous casting plant during a standstill of the downstream rolling mill in the overall system can be introduced into the furnace without problems and stored therein until normal rolling operation begins again.
  • this object is achieved in that, according to the characterizing part of claim 1, the cast strand sections separated from the cast strand are only introduced directly into the furnace and stored therein with transverse transport, in that the furnace is operated essentially without additional energy supply and the cast strand -Tiles are stored therein over a period of time which corresponds to a multiple, for example four times their casting time, but that the rolling of each individual cast strand section is carried out in a time unit which is only a fraction, for example one fifth corresponds to its casting time, and 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 time.
  • the process steps indicated advantageously ensure that each casting strand section remains in the furnace for a relatively long period between the end of the casting process and the beginning of the rolling cycle and as a result practically without additional energy being supplied from the solidification temperature of the casting strand to the required one within this period Rolling temperature of the cast strand sections brought and also held on this. Since between the storage and the start of rolling there is always a larger number of cast strand sections with a stretched length in the furnace, a temperature profile that is practically uniform over the entire length is obtained, especially since the cast strand sections from the continuous casting system also during the rolling operation can reach the oven.
  • assembly times on the rolling mill for example the roll changes, are placed in the pause times of the rolling cycles and, if necessary, the pause times of two rolling cycles are placed directly one behind the other, and that the cast strand sections formed during these pause times are additionally placed in the furnace introduced and stored in it.
  • Break times of about 10 minutes between successive rolling cycles are usually sufficient to carry out the assembly work (roll change) required on the rolling mill. Only if it turns out that an available pause time is not completely sufficient for the completion of the assembly work, then two pause times can advantageously be lined up directly, to which two rolling times can then be directly lined up to subsequently achieve the normal course of further rolling cycles.
  • a system for carrying out the method explained in detail above consists of a continuous casting system for the continuous casting of a band-shaped cast strand, of a cross-dividing device for dividing the solidified cast strand into cast strand sections and of a temperature compensation and storage furnace with transverse transport for receiving the cast strand sections in stretched length, which contains a plurality of storage locations for cast strand sections which can be operated by the transverse transport.
  • the storage furnace with its transverse transport is set up for direct loading with cast strand sections from the continuous casting installation, that it has the first storage location of the transverse transport axis alignment with the continuous casting installation, while at the last storage location of the transverse transport via one Abrollrollgang the rolling mill is connected, and that the number of storage spaces for cast strand sections on the transverse transport is matched to the difference between their necessary residence time in the furnace to the casting time for a single cast strand section.
  • the storage furnace has at least four according to the ratio 4: 1 Storage locations for cast strand sections.
  • the storage furnace contains, in addition to the storage locations for continuous casting sections on the transverse transport, buffer storage locations for continuous casting sections, which are in continuous operation of the continuous casting system during extended downtimes of the rolling mill between the rolling times of two successive rolling cycles, cast iron sections can also be fed in extended lengths.
  • the storage locations are essentially horizontally next to one another in the storage furnace, 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 plant can be taken up with relatively little additional effort and space without affecting the storage spaces in the storage furnace and can be completely eliminated after the rolling mill downtime has ended by appropriately increasing successive rolling cycles Roll out to the steel strip without any problems, because then - with the same rolling time - the successive rolling cycles are shortened by reducing their break times accordingly.
  • the number of buffer storage spaces is provided at least equal to the number of storage storage spaces 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.
  • 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 cast 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 4a 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 needs a casting time of 12.5 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 12, 5 minutes must be carried out a transport step and that the passage time of each cast strand section 4a through the storage furnace 5 is about 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 ° C. - the rolling temperature - while maintaining their elongated length relative to the inlet temperature at 1150 ° C.
  • 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 12 is fed to a take-up reel 14 via a driving device 13 and is wound by the latter into a coil.
  • the roller conveyor in the storage oven 5 assigned to the last storage location of the transverse transport 6 can be designed as a pendulum roller table, with the aid of which the cast strand section 4a located thereon can be moved back and forth within the storage oven 5 to a limited extent as required in the longitudinal direction.
  • each individual rolling cycle comprises a pause time of approximately 10 minutes, during which the continuous finishing train 9 and consequently also all parts of the plant downstream of it can go out of operation.
  • the continuous operation of the continuous casting machine 1 must also be interrupted. I.e. 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.
  • the storage furnace 5 is also equipped with buffer storage locations 15 for a larger number of cast strand sections 4b which are located in a region of the storage furnace 5. which lies to the side of the area containing the transverse transport 6.
  • the buffer storage locations 15 are arranged one above the other in the vertical direction, in such a way that they can be adjusted individually and in succession on the transport plane of the roller table 2 for the cast strand sections 4a and 4b by means of a lifting device 16.
  • a special transfer device is provided between the runway arranged in the area of the transverse transport 6 and in extension to the roller table 2 and the buffer storage locations 15 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 such that it effects transport steps in only one transport direction, in the case of the transfer device assigned to the buffer storage locations 15, 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 transfer device While it is necessary to carry out transport steps from the transverse transport 6 to the buffer storage spaces 15 in order to load the buffer storage spaces 15 with cast strand sections 4b, the transfer device must later transport movements to the transverse transport 6 in order to empty the buffer storage spaces 15 later run out.
  • the number of buffer storage spaces 15 in the storage furnace 5 is made at least equal to the number of them Select storage locations.
  • the number of buffer storage locations 15 is selected to be even larger than that of the storage storage locations. This is because there are five buffer storage locations 15 with 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 thus take over from the buffer storage locations 15 to the storage locations of the transverse transport 6 in the storage furnace 5.
  • FIGS. 4 to 6 differs from that of FIGS. 1 to 3 basically only in that the storage furnace 5 instead of a continuously working finishing train 9 with four-high mill stands assigned a four-high mill stand 17 with reversing operation which works as a Steckel mill with an outlet-side coil reel or reel furnace 18 and an inlet-side coil reel or reel furnace 19.
  • Continuous casting machine 1 and storage furnace 5 are completely identical in construction and mode of operation with the system according to FIGS. 1 to 3.
