Description

Process and casting and rolling plant for producing steel strip,

The invention relates to a method and a casting and rolling plant for the production of steel strip, in particular stainless steel strip, by casting, with subsequent rolling in a hot wide strip mill, at the entrance of which are cast, thick slabs (approx. 120 mm - 400 mm) a warming-up furnace before the hot strip mill.

Conventional hot wide strip mills have a lifting beam furnace at the entrance, in which thick slabs (between approx. 120 mm - 400 mm thick) are introduced and brought to the temperatures required for the rolling process by heating. An immediately conceived casting and rolling process is still considered to be impossible for technical, procedural and / or economic reasons. However, due to the provision of a CSP continuous casting device in front of a conventional hot wide strip mill, advances have been made which continue to make this development appear advantageous and economical to an extent never known before.

To bridge a comparatively short interruption in the rolling process, it is known to insert a strand piece resulting from the continuous casting process into a correspondingly lengthened buffer zone of a compensating furnace, with longer buffer sections being uneconomical (DE 40 17928 A1).

An interruption between a continuous casting process and a rolling process can then be minimized in that the continuously cast strip product is wound up after casting and by intermediate heating is brought to the entry temperature required after unwinding before entering the hot wide strip line. However, precautionary measures must be taken for the heat losses that occur (DE 37b 14432 C2).

An approximation of the casting speeds of the continuous casting device to the required rolling speeds is achieved in a continuous casting-rolling process by successive work steps in which the solidified primary material is divided into pre-strip lengths by means of a partial device (scissors) and after descaling the surface in a compensating furnace at rolling temperature is brought (DE 195 29 049 C1). Nevertheless, energy losses can still be tolerated to a greater extent here.

It has also already been proposed to place at least two continuous casting plants in front of a hot rolling group, to allocate a furnace of great length to each continuous casting machine and to design the furnaces to be displaceable in a transverse manner and to shift them into the common rolling line. Although this increases the number of continuous cast sections located at the rolling temperature, the method requires that entire furnaces can be moved (EP 0 893 167 A2).

A method and a plant for the production of hot wide strip from in particular thin slabs is also known (DE 198 39 370 A1), in which the separated thin slabs, homogenized in a compensating furnace, are brought into the finishing mill via a storage furnace and a holding furnace. The steelworks, blast furnace, casting machine, leveling furnace and hot rolling mill are to be logistically connected to one another in order to utilize the maximum performance of the individual components. The ovens are connected to each other via reverse swivel ferries.

In general, the state of efforts is limited in that a continuous casting device is matched to the hot strip mill in that strip-like primary material is divided into preliminary strip lengths after solidification and the pre-strips are heated to rolling temperature in a compensating furnace.

The invention is based on the object of proposing measures for improved coupling of a continuous casting installation to a hot wide strip mill which have a process-related and economically advantageous effect on the casting and rolling process.

The object is achieved in terms of process technology in that continuously cast thin slabs (approx. 30 mm - 70 mm) and medium continuously cast slabs (approx. 70 mm - 120 mm) in rolling mills used for continuously cast, thick slabs (approx. 120 mm - 400 mm) are determined, in the rolling direction behind, heating furnaces consisting of walking beam furnaces are to be introduced. As a result, existing and future hot wide strip mills can be retrofitted with continuous casting plants of the highest technology level, or vice versa. Thin and thick slabs can consequently be rolled in a strip mill of the same design.

The method can also be carried out in such a way that when a thin slab enters the roughing and / or finished rolling mill, its temperature is equal to or significantly below or above that of a medium slab when entering the Vόr rolling mill and / or the finished rolling mill, or the thickness of the thin slab is the same or is below or above the thickness of a medium slab when entering the roughing and / or finishing mill. This principle applies to the greatest thickness of a thin slab and the smallest thickness of a thick slab, so that there can be a corresponding thickness between the medium or thick slab or the thin or medium slab. This gives the hot strip the comparable inlet thicknesses and temperatures of the thick slab when entering the roughing and finishing train. If the thin slab temperature is low, the better temperature homogeneity of the thin slab can compensate for the disadvantage of the temperature difference. same. The roll stands can be adapted to the increased input thickness.

The casting and rolling plant for the production of steel strip, in particular stainless steel strip, is equipped with a continuous casting device and a partial device, which is followed by a hot strip mill, in front of the entrance for thick slabs (approx. 120 mm to 400 mm) a heating furnace and in the further course of the rolling mill Edge smoothing rolls, descaling devices, winding devices u. Like. Are provided, equipped.

The coupling of the continuous casting device to the rolling mill is now carried out according to the invention in such a way that the connection of the continuous casting device to the hot strip mill consists of a partial device arranged at the outlet of the continuous casting device, a tunnel kiln and a parallel or swivel ferry or in their place by means of a coil box device is. As a result, the continuous casting apparatus is technically and economically more advantageously connected to the strip rolling mill. A largely continuous operation from liquid steel to hot strip without intermediate stages can be achieved, which saves costs. It will be possible to expand the product range with geometric and metallurgical properties that could not be achieved on conventional hot wide strip mills. It is also possible to increase the capacity of the hot strip mills that have been built to date.

One embodiment consists in that an in-line rolling device, then the partial device, the tunnel kiln and then the coil box device and a coil handling device are provided in the continuous casting device.

A further development provides that two or more continuous casting devices with a parallel course of the casting strand and each of the following sub-device and each of the tunnel kiln and at the tunnel kiln exit by means of a parallel ferry is connected to the rolling line of the roughing and finishing mill.

The process for producing steel strip 1, in particular stainless steel strip, by casting with subsequent rolling in a hot wide strip mill, at the entrance of which continuously cast, thick slabs (approx. 120 mm to 400 mm) are introduced from a heating furnace in front of hot strip mill 4 in such a way that continuous cast thin slabs (approx. 30 mm - 70 mm) and medium continuous cast slabs (approx. 70 mm - 120 mm) in rolling mills, which are suitable for continuous cast thick slabs (approx. 120 mm - 400 mm) are intended to be introduced behind in the rolling direction 3a, consisting of walking beam furnaces 11, heating furnaces.

The method can also be carried out in such a way that when a thin slab enters the roughing and / or finished rolling mill, its temperature is equal to or significantly below or above that of a medium slab when entering the roughing mill 10a and / or the finished rolling mill 10b or the thickness of the thin slab is the same or below or above that thickness of a medium slab when entering the roughing and / or finishing mill 10a, 10.

The casting and rolling system for producing the steel strip 1, in particular stainless steel strip, in which the outlet 2a of the continuous casting device 2 is inline or offset from the rolling line 3 to a compensating furnace of the hot strip mill 4, has in the order a sub-device 5, the tunnel furnace 6, in Rolling direction 3a behind the compensating furnace at least the rolling stands of the roughing and finishing rolling mill, edge smoothing rollers, descaling devices, strip winding devices 16 u. Like.

Within the continuous casting device 2, an inline rolling device 8, followed by the sub-device 5, the tunnel kiln 6 and the hot belt line 4, a coil box device 9 and a coil handling device 9a are then provided.

According to FIG. 1, two or more continuous casting devices 2 with a parallel course of the continuous casting wire 2b and each with the subsequent part device 5 (for example a cross-part device) and each with the tunnel kiln 6 and at the tunnel kiln exit 6a by means of a parallel ferry 7a to the rolling line 3 the roughing and finishing rolling mills 10a, 10b connected. A tunnel kiln parallel ferry 7a is moved back and forth between the casting strand wires 2b. In the rolling line 3, following the tunnel furnace parallel ferry 7a, one or more walking beam furnaces 11 are arranged before the strip entry into the roughing and finishing rolling lines 10a, 10b, which precisely determine the inlet temperature of the hot strip line 4. The steel strip 1 is rolled to a final thickness and / or flatness in a finishing stand 14 or a roller mill 15 and wound on the strip winding device 16 to form a strip bundle.

2A, parallel casting strands 2b of the continuous casting device 2 to the rolling line 3 are assumed. In a rear parallel section 12 there are at least the continuous casting device 2, the partial device 5, the tunnel furnace 6 and the parallel ferry 7a. In a front parallel section 13, one or more walking beam furnaces 11, a roughing mill 10a, the parallel ferry 7a and the finishing mill 10B, the finishing stand 14 or a Steckel mill 15 and the strip winding device 16 are arranged. As a result, the parallel ferry 7a lies between the roughing mill 10a and the finishing mill 10b. The conveying directions run parallel.

2B, the parallel arrangement of the casting strand 2b to the rolling line 3 is maintained. However, the parallel ferry 7a is laid in the rolling direction 3a in front of the roughing and finishing rolling mills 10a, 10b. Accordingly, the walking beam furnaces 11 are shifted to the length of the parallel ferry 7a. 2C, a further modification of the concept is made in that, in the case of a parallel casting strand 2b of the continuous casting apparatus 2 to the rolling line 3 in the rear parallel section 12, the continuous casting apparatus 2 with a casting strand core 2b running in the opposite direction to the rolling direction 3a, the subassembly 5, the tunnel furnace 6 and the Parallel ferry 7a and in the rolling direction 3a the parallel ferry 7a are arranged behind the roughing and finishing rolling mills 10a, 10b. Accordingly, the parallel ferry 7a lies in front of the finishing stand 14 or the plug-type rolling mill 15 on the rolling line 3.

According to FIG. 3A, the continuous casting wires 2b of two continuous casting devices 2 arranged at a lateral distance run parallel. The partial device 5 and the tunnel furnace 6 follow in each case. The rolling line 3 is arranged centrally between the casting strand cores 2b. The connection at the beginning of the rolling line 3 consists of a center swivel ferry 17 which alternately swivels the rolling stock into the rolling line 3 from both continuous casting devices 2.

In FIG. 3B, in the case of parallel continuous casting 2b of two continuously arranged casting devices 2, a rolling line 3 running centrally between the continuous casting wires 2b is provided. In front of the roughing and finishing rolling mills 10a, 10b there is a central parallel conveyor 7a in a double arrangement in order to feed the continuous casting products from both continuous casting devices 2 to the rolling line 3.

According to FIG. 4A, the continuous casting wire 2b runs parallel to the laterally spaced rolling line 3. The connection here consists of a swivel ferry 7b on the line of the casting strand wires 2b and a second one on the rolling line 3. The transfer takes place in the angular position of the two swivel ferries 7b of the continuous casting product instead.

The embodiment according to FIG. 4B is in turn designed for two parallel, counter-rotating casting strand 2b. Each cast strand 2b is with one

Swivel ferry 7b equipped. There is also one on the central rolling line 3 Arranged swivel ferry 7b, which serves one or the other cast strand 2b depending on its swivel position. In the exemplary embodiment, the central swivel ferry is between the roughing mill 10a and the finishing mill 10b. The two continuous casting wires 2b essentially take up the length of the rolling line 3.

5A, the casting strand 2b and the rolling line 3 run in opposite directions. Within the continuous casting device 2, an inline rolling device 8 is assigned to the section in front of the sub-device 5. A transversely displaceable coil box device 9 is arranged at the end of the continuous casting wire 2b, so that the wound continuous casting product can be transferred to the rolling line 3 in a coil.

The concept from FIG. 5A has been further developed in the embodiment of FIG. 5B. The cast strand 2b runs differently than in FIG. 5A; 5B is a course to the rolling line 3 e.g. provided in the same direction 19. In the rolling direction 3a, a transversely displaceable coil box device 9 is arranged in front of the roughing and finishing rolling mills 10a, 10b.

5C, the coil box device 9 with the coil handling device 9a is arranged behind the roughing and finishing rolling trains 10a, 10b in the opposite direction 18 of the rolling line 3 in the opposite direction 18 of the rolling line 3.

6, two parallel casting strands 2b are arranged perpendicular to the rolling line 3 behind the roughing and finishing rolling trains 10a, 10b. The connection of the casting strand wires 2b requires a 90 ° swivel of the coil in the rolling line 3. The parallel arrangement of two casting strand wires 2b is connected to the arrangement of two stations 20 for the coil box device 9 lying next to one another. The design of FIG. 6 is modified by the design in FIG. 7 in such a way that the two casting strand wires 2b are arranged in opposite directions perpendicular to the rolling line 3.

FIG. 8 shows the conception of the cast strand strands 2b running in opposite directions, which run perpendicular to the rolling line 3, by means of an inline arrangement of the two strands 2b running in opposite directions with coil box devices 9. The coils can also be swiveled by 90 °.

According to FIG. 9, the opposing casting strand wires 2b can be connected to an end station 20a of the coil box device 9 in such a way that a 90 ° swivel of the coils in the rolling line 3 is not necessary.
