Definitions
- the invention concerns a method and an installation for producing hot-rolled strip from a highly cold-workable, high-strength, austenitic light gauge steel with increased contents of manganese (Mn), aluminum (Al), and silicon (Si) with TWIP properties (Twinning-Induced Plasticity), wherein the steel is first cast into an endless strand in a continuous casting installation, cut into slabs, and then rolled to the final thickness.
- Mn manganese
- Al aluminum
- Si silicon
- Austenitic light gauge steels with TWIP properties for use, e.g., in automobile body parts, reinforcing automobile body members, and cryogenic tanks and pipelines have, for example, according to EP 0 889 144 B1, a chemical composition of 10-30% Mn, 1-6% Si, 1-8% Al (with Si+Al ⁇ 12%), with the remainder consisting of Fe.
- DE 199 00 199 A1 discloses a high-strength light gauge steel with 7-30% Mn, 1-10% Al, 0.7-4% Si, ⁇ 10% Cr, ⁇ 10% Ni, ⁇ 3% Cu, ⁇ 0.5% C, and optionally with the additional alloying elements N, Va, Nb, Ti, and P, which has not only good mechanical properties but also good resistance to corrosion and stress-corrosion cracking.
- This steel is intended to be cast by continuous casting and hot rolled or to be cast by thin-strip casting with near-net shape.
- WO 02/101109 A1 discloses a method in which a significant reduction of the offset yield stress and thus an improvement of the formability by hot rolling and cold rolling are achieved by increasing the possible carbon content (C ⁇ 1%) and by adding additional elements, here especially B as well as Ni, Cu, N, Nb, Ti, V, and P.
- a feedstock (slab, thin slab, or strip) is heated and hot rolled and coiled within specific temperature limits.
- EP 1 341 937 B1 describes a method in which a steel containing 12-30% Mn is cast in a twin-roll casting machine into a near-net shape thin strip with a thickness of less than 1 mm to 6 mm.
- the near-net shape strip emerging vertically from the casting gap is cooled by coolants applied to its surface and is then rolled to the final thickness in a single hot rolling pass.
- the total time interval between the exit from the casting gap and the entry into the rolling stand is about 8 seconds.
- EP 1 067 203 B1 discloses a method for producing strip made of an Fe—C—Mn alloy in which a thin steel strip with a thickness of 1.5-10 mm and a composition of 6-30% Mn, 0.001 to 1.6% C, ⁇ 2.5 Si, ⁇ 6% Al, ⁇ 10% Cr and other elements is first cast on a twin-roll casting machine and then hot rolled in one or more stages with 10-60% reduction.
- the objective of the invention is to specify a method and an installation which can be realized as simply as possible and with which high-manganese steels with a given chemical composition can be produced by continuous casting.
- An installation for carrying out the method is characterized by the features of Claim 7 .
- Microsegregations that are still present in the strand after solidification are largely removed again by diffusion during passage through the intermediate furnace, for example, through a roller hearth furnace, before the subsequent rolling deformation.
- the macrosegregations in the slab center are sufficiently equalized during the intense deformation in the hot rolling mill, much like high-grade austenitic steels.
- the use of the roller hearth furnace of a CSP installation advantageously avoids any relatively great depletion of the alloying elements and oxidation of the grain boundaries due to the short passage time. Depletion of the alloying elements and oxidation of the grain boundaries can cause problems, for example, during the relatively long heating times in the pusher furnace of a conventional hot-rolled wide strip mill in accordance with the prior art.
- a suitable flux powder is one which has the property of achieving equilibrium very quickly and then undergoing no further change in its lubrication behavior.
- the flux powder used in accordance with the invention has a high content of Al 2 O 3 of >10%.
- the SiO 2 content of the flux powder is increased sufficiently to obtain a basicity (CaO/SiO 2 ratio) of 0.5-0.7.
- MnO 2 is more readily reduced than SiO 2 by the Al in the steel, and thus the SiO 2 is protected from this reduction (protected from loss), an additional measure that can be taken in accordance with the invention is the addition of MnO 2 to the flux powder.
- TiO 2 it is also possible to add TiO 2 to the flux powder as a partial replacement of the SiO 2 , since TiO 2 also has a vitrifying effect but is not attacked (reduced) by the Al in the steel.
- the installation is basically a well-known CSP installation, in which, in accordance with the invention, the distances between the individual installation units were changed in such a way that the method of the invention can be carried out with the requirements that temperature equalization is brought about in a continuous-type intermediate furnace immediately after the solidification and that the slab is then immediately hot rolled without intermediate cooling.
- the installation illustrated in the drawing consists of a thin-slab casting machine 1 and a downstream intermediate furnace 4 , into which the slab 3 is fed after it has solidified and has been cut from the endless strand 2 .
- the intermediate furnace 4 is followed by a rolling mill 5 , in which the slab 3 , after it has been subjected to temperature equalization in the intermediate furnace 4 , is immediately (i.e., without intermediate cooling) rolled out into hot-rolled strip 6 .
