Definitions
- the invention relates to a method for operating a Casting and rolling system (see e.g. EP-A-0584605).
- the known casting and rolling systems at least include a casting machine whose slabs without intermediate storage be fed to at least one tunnel kiln.
- the tunnel oven flows into a rolling mill (finishing train) with at least one Rolling stand.
- the slabs become hot strips rolled.
- the rolled hot strips fed to at least one cooling section and rolled up on at least one reel.
- a casting and rolling system is thus by coupling the in the conventional sheet steel production decoupled processes Slab pouring and hot rolling marked.
- Attachments of the Steel industry thus consist of at least three components, namely the steelworks in which steel is produced from pig iron , the slab production line, which has at least one caster (Casting machine with downstream tunnel furnace), and the rolling mill (finishing mill).
- the maximum possible production is either with two casting plants with each a casting strand or with a two-strand casting plant.
- the rolling capacity of the rolling mill can be in the known casting plants cannot be fully used due to the casting performance (Casting speed and casting cross section) of the casting machine (s) cannot be increased beyond certain limits can to avoid technical and qualitative problems. Despite full casting operation, this means that the rolling mill rolls faster than the casting machine or casting machines Can deliver slabs.
- the unused production gaps are u. a. the necessary set-up times for the casting machines due to distributor, mold, or segment change, the planned Downtimes due to maintenance work, as well as the unplanned downtimes due to malfunctions in the casting operation. This means that the rolling mill then either at all cannot roll or only roll with extended breaks.
- the object of the present invention is therefore a method to operate a casting and rolling system with which a higher throughput in the production of strip material can be realized.
- the method of claim 1 is for operating a casting and rolling system suitable the at least one slab production line and at least one rolling mill and at least one Includes slab feeder, the manufacturing technology is independent of the slab production line. While a production break of the slab production line the slab feeder takes over the slab feed to the rolling mill according to logistical and / or production-technical specifications up to the maximum feasible Scope.
- the invention thus uses previously unused roll breaks the casting and rolling mill through optimized logistic specifications in a modified plant configuration that includes a slab feeder contains.
- the invention provides a suitable production planning method available on the type of advanced configuration the casting and rolling system is coordinated.
- the through the Slab feeder supplied slabs are additional rolled in the rolling mill without the basic Equipment of the specially configured casting and rolling system needs to be changed. This allows the throughput at the production of strip material can be increased significantly.
- the slab feeder can Manufacturing technology independent of the slab production line is, their slabs z. B. from another Preserved slab production line.
- the further slab production line takes over together with the slab feeding device the slab feed to the rolling mill according to logistical and / or technical production requirements up to maximum achievable scope (method according to claim 2).
- the further slab production line can be a thick slab production line be trained together with the slab production line the slab feed to the rolling mill according to logistical and / or technical production requirements up to maximum realizable extent (procedure according to claim 4).
- the method according to the invention is advantageous according to another Design also suitable for casting and rolling systems, who receive their slabs from a slab warehouse where the prefabricated Slabs to be buffered in terms of production (process according to claim 5).
- the further thin slab production line can e.g. B. from a there is another casting machine which has a casting strand and a suitable extension of the slab ferry mechanism in the tunnel kiln for feeding into the rolling mill.
- This configuration one will choose if steel grades are produced should be able to withstand the high casting speeds, so Normal steels.
- An additional conventional slab production line that thick slabs over at least one heating furnace and over rolls at least one (reversing) roughing stand into thin slabs, and provides them via a holding furnace on the rolling mill.
- This configuration will be chosen when the additional Slab production line produce steel grades should not tolerate high casting speeds, so z.
- the slab feeder of the rolling mill Slabs more logistically and / or more technically Specifications are supplied. So it comes in particular does not depend on the type of further slab production line.
- the invention enables optimized production plans for the operation of the casting and rolling mill at full capacity Rolling mill generated.
- the plant plans for the individual parts of the casting and rolling system are derived become. These are melting plans and casting plans as well as slab application plans and rolling plans.
- the necessary melt sequences are determined by the melt plans in at least one of the casting and rolling machines Steelworks created, including the chronological order for the timely delivery of the melts to the casting machines.
- the casting plans describe the production of the thin slabs in the casting machines of the casting and rolling plant or in the conventional Casting machine of the further slab production line, including the casting sequence, the melt sequence and the Slab sequence for each slab production line.
- the slab deployment plans determine the use of the slabs in the further slab production line depending on Cold, warm or hot use.
- the To plan the sequence and the time sequence so that the Slabs in time on the rolling mill to use previously unused Roll breaks are available in the casting and rolling system.
- the slabs are rolled out of all Slab production lines, including timing of the slab insert from the tunnel kiln of the casting and rolling mill, planned in this way, that the rolling breaks cheaply through the further slab production line can be used. Also finds one Planning the roll changes necessary in the rolling mill at Consideration of the buffer times in the ovens instead.
- the first production line I comprises a casting machine 1, in which thin slabs 2 are poured. These thin slabs 2 are fed to a tunnel furnace 3.
- the casting machine 1 and the tunnel kiln 3 together form a slab production line 40 (casting machine).
- the tunnel kiln 3 opens into a rolling mill 4, in the illustrated embodiment has six roll stands 5.
- the rolled hot strips 6 become one Cooling section 7 fed and rolled up on a reel 8.
- the first production line I another casting machine 11.
- Die Casting machine 11 is parallel to the casting machine in terms of production technology 1 arranged.
- the casting machine 11 also produces Thin slabs 12. These thin slabs 12 become a tunnel kiln 13 supplied, the production technology within the first production line I. is arranged parallel to the tunnel furnace 3.
- the casting machine 11 and the tunnel furnace 13 form together a slab production line (casting plant), designated 50 is. Those produced by the slab production line 50 Thin slabs 12 are then also the rolling mill 4 fed (arrow 14).
- the slab production lines. 40 and 50 form a two-strand caster.
- a second production line II is arranged.
- the second production line II in the illustrated Casting mill a slab feeder 20.
- the Slabs 22 a reheating furnace 23 and a downstream (Reversing) roughing stand 24 can be fed.
- rolled pre-strips are called coils 25 from a coil box 26 added.
- the slab feed device 20 is in the inventive Manufacturing technology independent of Slab production line 40 and 50 controlled.
- the casting and rolling system also includes a coil transport device, through which the coils 25 in front of the rolling mill 4 of the second production line II into the first production line I be transferred.
- the coil transport device is for reasons the clarity is not shown in the drawing.
- To feed the pre-strips the coils 25 are removed from the coil box 26 removed and transported to the entrance of the rolling mill 4
- the supply of the coils 25 is by an arrow 27 symbolizes.
- the Coil box 26 a holding oven 21 for storing the coils assigned (double arrow 29).
- the embodiment shown is through a slab production line 30 expanded.
- the slab manufacturing facility 30 is in front of the slab feed device 20 arranged.
- the slab production line 30 includes a casting machine 31 in which slabs 22 are cast. This Slabs 22 become the slab feeder 20 fed directly (warm or hot use).
- the slab feeder 20 in turn guides the slabs 22 to the reheating furnace 23 to (arrow 28).
- Both those produced by the slab production line 30 Slabs 22 as well as the externally produced slabs can in a slab storage 34 buffered in terms of production technology (arrow 33 or arrow 35) and if necessary, the slab feed device 20 are fed (arrow 36, cold use).
