Definitions
- the invention relates to a process for the continuous production of steel strip or sheet steel from flat products produced by the sheet continuous casting process with a horizontal outlet direction.
- the last stand of the rolling mill results in rolling speeds which are too low in order to be able to maintain the required final rolling temperatures of at least approximately 865 degrees C. That , the strip experiences too much cooling between one rolling stage and the subsequent one, owing to the low speed identical to the casting speed when it enters the rolling train.
- One has moved away from this solution because the problem could not be solved economically even with heat protection devices and heated rollers; because this would result in a significant increase in investment and operating costs.
- Another proposed solution provides for the strip to be cut off in front of a heating furnace, in which the strip is then heat-treated (temperature compensation) over its entire cross-section.
- This can be, for example, a gas-heated roller furnace, with which a strip temperature of approx. 1100 degrees C can be set independently of the casting speed to be taken into account at the furnace outlet, that is to say an optimum temperature for the subsequent rolling process.
- the strip is cut to a standard length, which can be, for example, 50 m for a specific coil weight, for which a corresponding furnace length of approximately 150 m is required if the required buffer effect is taken into account.
- the thin slab or the "preliminary strip” can be rolled out at higher speeds, and there is therefore no fear of the temperature dropping below the minimum temperature permitted for the final rolling stage.
- the excess length of the furnace which is approximately 3 times the length of the strip section, also results in an enormous space requirement, on which many steelworks are not equipped.
- the dimensions of the system and thus of the furnace set limits for the length of the successive strip sections to be treated and thus also for the final coil weight, which in turn limits the scope for use with regard to the production of coils with the largest diameter. Accordingly, a plant of this type does not offer the possibility of using even thinner starting slabs, should this become possible due to the technological development of the continuous casting process. Assuming an initial thickness of 25 mm - as has already been hypothetically done - instead of 50 mm, the band would have to be divided into lengths of approximately 100 m in order to achieve the same final bundle weight, for which a length in for the treatment furnace would have to be provided on the order of 300 m, which is convenient and economic ⁇ Lich not feasible.
- the aim of the present invention is to create a method of the type described at the outset and a corresponding system for carrying out this method, with which steel strip can be produced continuously from flat product coming from a continuous sheet caster without taking on the aforementioned disadvantages.
- the tapping of the casting strand in the first roll stand being carried out at the speed at which the rolling stock leaves the arc section of the continuous casting installation.
- the process is thus said to be carried out "in line” with practically unlimited flexibility, so that it is possible to produce coils of any weight and length or sheets without changing the dimensional parameters of the system, since the rolled strip is separated at least after the first Rolling process or after all operations are carried out immediately before the reel-up or stacking device.
- the rolled-out strip can be reeled in according to the desired coil weight following the shaping of the flat product or, after the rolled-out strip has been separated off after the shaping of the flat product, can be stacked in predetermined lengths into sheet steel packages, if necessary after cooling and straightening.
- the flat product is thus first pierced in a first roll stand at the output speed of the product from the continuous sheet casting installation and passes through the successive rolling stages at speeds corresponding to the deformations in the individual passes.
- the thus-rolled strip is then either coiled and, after the coil weight is reached desired, separated or the tape is divided into ge desired lengths and stacked in sheets.
- An essential aspect of the present invention is the inductive re-heating of the flat product after descaling to temperatures of approximately 1100 degrees with the best possible temperature compensation, because in this way an undercooling of the strip can be counteracted in a favorable manner.
- the starting strand After passing through the rolling stands, the starting strand can be cut off with the device which is present anyway for dividing the rolled strips, or it can be cut off by a further separating device downstream of the first deformation stage.
- the separating device can be arranged behind the first deforming device and between the first deforming device and the further deforming device there can be a device for winding and unwinding the flat product, which is arranged upstream of the separating device.
- the device for winding and unwinding the flat product is preferably arranged behind the device for inductive heating and in front of the further deformation device.
- either a separating device for the rolled strip and at least one reel for winding the strip is arranged downstream of this system, or a separating device for the rolled strip, a cooling device, a straightening machine and a stacking device for the separated metal sheets.
- the system additionally comprises at least one device for inductive heating for intermediate heating between the further rolling stands.
- the system is also equipped with devices for adjusting the cross-section of the passage between the rollers of the first shaping device and the further rolling stands in order to enable the start-up strand located at the head of the casting strand to pass and immediately after it has passed Cross sections can be traced back to the usual throughput values.
- the separating device for separating the starting strand is used, which is located behind the first deformation stage.
- Fig. 3 shows a modified embodiment of the invention.
- the system according to the invention is roughly shown schematically, by means of which the corresponding method is described.
- a continuous casting mold which is identified in the drawing by 1
- the flat product 2 is produced.
- the flat product 2 guided and transported in conventional support rollers passes from the initial vertical direction over the arc section formed by the support rollers the horizontal position over.
- the flat product according to the invention passes through a first deformation stage 3, in which it is brought to a maximum thickness of 25 mm, for example.
- the deformation stage 3 can consist of one or more rolling devices, preferably in a four-way arrangement.
- a furnace 5 which is preferably equipped with an inductive heating device.
- this furnace 5 there is a temperature equalization over the entire cross section of the flat product 2, so that it reaches the first stand 6 of the further shaping device with a sufficient rolling temperature. If a piercing speed which is too slow, corresponding to the speed at exit from the sheet path, leads to a considerable drop in temperature, so that an insufficient deformation temperature results in the second roll stand 7 of the further deformation device, then further intermediate heating can possibly take place in the form of a second induction furnace 8 between the roll stands 6 and 7, which can be shorter than the furnace 5.
- the second induction furnace is only required if the furnace 5 is not sufficient to move along the entire length during the deformation three rolling stands 6, 7 and 9 existing further deformation device to set the corresponding temperature gradient, in such a way that when the last rolling stand 9 is pierced, the temperature is within the order of magnitude sufficient for good deformation.
- the flat product 2 now referred to as strip 2 1 , has the desired thickness.
- the method concludes either by reeling the rolled strip 2 1 on the reel 11 and severing at 10 after reaching the desired bundle or "coil" weight, or by severing the strip 2 1 in desired lengths and then stacking on a stacking device 12, which is shown schematically in FIG. 2.
- the device for severing the belt 10 at the beginning of the work cycle can also be used to sever the starting strand (not shown here) which, after passing through the switched-off induction furnace 5 and the extended rollers of the shaping device 6, 7 and 9, and so on the possibly provided and also switched off intermediate heating device 8 is separated.
- Corresponding adjusting devices are provided, by means of which the rollers are re-adjusted to the normal nip required for the deformation immediately after passing through the starting strand.
- the heating devices 5 are preferably composed of mutually independent zones, so that, starting from the state of the switched-off furnace, the furnace zones passed through by the starting piece are successively switched on for heating.
- the flat product 2 resulting from the casting and rolling process has a temperature of 1075 degrees C on leaving the first deformation stage 3, which drops to 1049 degrees C on the way to the descaling device 4. Due to the press water descaling provided in this arrangement, the temperature suddenly drops to 969 degrees C and cools down to furnace 5 to 934 degrees C.
- the temperature rises again to 1134 degrees C, with temperature compensation taking place over the entire cross section of the flat product.
- the latter experiences a decrease in the temperature to 1104 degrees C before reaching the mill stand 6, which due to the contact with the rolls in the mill stand is only 1063 degrees C as it exits the mill stand.
- the partially rolled strip is heated in an intermediate inductive furnace 8 from 1020 degrees C to 1120 degrees C.
- the temperature is 1090 degrees C and drops again to 1053 degrees C when leaving the roll stand until it has dropped to 988 degrees C when entering the third and last roll stand 9.
- This temperature is sufficient as the piercing temperature for the last rolling process; the rolling stock 2 1 leaves the last rolling stand 9 at a temperature of 953 degrees C and is then separated and stacked in desired lengths at a still further reduced temperature or is wound up as shown in FIG. 1.
- the speed in the exemplary embodiment when leaving the first deformation stage 3 is 0.08 m / sec. or 4.8 m / min. This corresponds to the piercing speed when entering the rolling stand of the further shaping device, where the thickness of the flat product is still 25 mm.
- the tapping speed when entering the rolling stand 7 is 10.2 m / min. with simultaneous deformation of the flat product from 25 mm to 12.3 mm.
- the rolling stock enters the last rolling stand at a speed of 19.8 m / min. and a thickness of 6.2 mm and leaves the mill stand with a finished thickness of 4.05 m and a speed of 30.6 m / min.
- the heating preceding the first roll stand of the further shaping device and, if appropriate, intermediate heating between the first and further roll stands must be set such that the flat product or the rolled strip is heated after the first pass to a temperature of approx. 1100 degrees C and the temperature level is maintained so that the final rolling temperature in the last rolling stand does not fall below the limit of 860 degrees C.
- a reel-up and reel-out device 12 is used.
- the coiling and uncoiling device is installed behind the induction furnace 5.
- the arrangement is supplemented by the descaling device 4.
- the winding and unwinding reel 12 is wound with flat material until the desired coil size is reached. After the wound bundle has been brought into the unwinding position (on the right in the drawing), the flat material is fed for further processing to the further shaping devices 6, 7 and 9, which consist of one or more shaping frames.
- an additional induction furnace 8 can be installed between the roll stands of the further shaping device.
- the finished bundle is at 11, e.g. on a downcoiler.
