Definitions
- the present invention relates to the technical field of cast-rolling compound plants. These are plants in a continuous casting plant for the continuous production of a steel strand with a slab format, e.g. Thin or
- the invention relates to endlessly operated cast-rolled composite plants in which the casting plant as a
- Thin slab continuous casting machine is formed (English TSER Thin S_lab Endless Rolling). In the process, the continuously produced in the continuous slab caster is endless
- Two-roll strip casters with a downstream rolling mill are also known from the prior art. Although a two-roll strip caster is very compact and produces a strip immediately, this technology has not been able to prevail until now, since in particular medium to higher alloyed steel grades can not be reliably produced.
- a cast-rolling composite plant for producing a steel strip in which between the continuous casting machine and the hot rolling mill, a milling machine 4 for milling a thin slab strand 3 is arranged.
- the mass flow of the continuous casting machine can be between 0.28 and 0.39 m 2 / min. Since the thin slab or the pre-strip is (intermediate) heated before the finish rolling, the hot rolling does not take place exclusively from the casting heat.
- WO 2007/054237 Al also discloses a cast-rolled composite installation for producing a steel strip.
- Mass flow of the system can be 0.441 m 2 / min. Since the pre-strip is preheated before the finish rolling, the hot rolling does not take place exclusively from the casting heat.
- the hot strip can be finish-rolled from the casting heat of the thin slab strand in the austenitic state.
- this concept requires very high casting speeds, eg, with a slab thickness of 50 mm, a casting speed of about 10 m / min.
- Casting speeds v c > 6 m / min are problematic because the reliability of the continuous casting machine decreases significantly. Attempting to achieve the specified specific throughput by using relatively thick slabs, for example, with a slab thickness of 100 mm by a casting speed of about 5 m / min, this leads to reliable conditions in the continuous casting, but the mill has many scaffolding (high CAPEX) to produce a hot strip with a thickness ⁇ 10 mm can. In the practical
- Pre-rolled Vorband typically has to be reheated after 3 or 4 rolling passes.
- today's cast-and-roll compound plants are usually operated at a casting speed of 5, 6 or 7 m / min and the pre-strip is reheated in an induction furnace. Due to the
- the object of the invention is to overcome the disadvantages of the prior art and to provide a method for the endless production of a hot strip of steel in a cast-roll compound plant and a compact, favorable cast-rolling compound of the type mentioned, with which high quality hot strip of various

- rolling passes is rolled to the hot strip with a thickness of 2.5 to 10 mm and the last roll pass is made in the austenitic temperature range of the steel;
- the aforementioned continuous casting mold is designed either straight or arcuate. However, a straight-through mold is preferred because impurities in the molten steel can be taken up by the casting powder and thus the internal quality of the thin slab strand is improved.
- Continuous casting mold has a thickness of 45 to 70 mm, preferably 55 to 65 mm, and a width of 900 to 2300 mm, preferably 1100 to 1900 mm.

- the actual position of the sump tip lies in the last third of the arcuate region of the strand guide or in the horizontal outlet region of the strand guide.
- the temperature of the hot strip at the last pass can be accurately adjusted when the actual temperature Ti actual of the hot strip after the last pass in the rolling line and before cooling in the cooling section is measured and the cooling of the thin slab strand in the strand guide and / or the casting speed v c is set regulated, so that the actual temperature Ti Ist a setpoint temperature ison as possible corresponds.
- the coiling temperature of the hot strip can be set exactly when the actual temperature T 2 i s t of the endless hot strip is measured after cooling in the cooling section and
- Cooling nozzles of the cooling section are controlled temperature-controlled, so that the actual temperature T 2 i s t a setpoint temperature T 2 soii corresponds as possible.

- the rolling train Since the rolling train is located immediately after the continuous casting plant, neither a heater nor a descaler is arranged between the end of the continuous casting plant and the first rolling stand of the rolling train. Thus, the thin slab strand enters after the continuous casting with high surface and core temperature in the rolling mill and is there
