Definitions
- the invention relates to a method for producing thin metal strip with a thickness of at least 0.6 mm and a maximum width of 1,800 mm an average width of 1,300 mm, which is continuously cast and rolled.
- the term metal strip includes in particular steel strip, which has a thickness of more than 0.6, preferably 1 mm.
- the present invention is therefore based on the object of process parameters or to determine system parameters so that a technical and cost optimized solution for the production of thin hot strip on a continuous casting and Rolling system is provided at high casting speeds.
- the essence of the invention is a capacity balance between the continuous caster and rolling mill with maximum productivity. This is an optimal one Speed and temperature coordination between the continuous caster, if necessary the roughing mill, the finishing mill and possibly the cooling section and the Adjust reel device.
- Process data in the individual production stages must be taken into account like that maximum casting performance, the maximum casting speed, the maximum metallurgical length of the continuous caster, i.e. the length to the top of the swamp, the minimum feeding speed of the (intermediate) belt into the finishing train and the maximum exit speed of the strip from the finishing train.
- the Process parameters necessary for this are specified according to the invention as follows:
- a strand with a casting speed of ⁇ 8m / min cast In a single-strand casting machine, a strand with a casting speed of ⁇ 8m / min cast. This strand runs through a direct endless network the rolling mill immediately downstream of the single-strand casting machine if necessary, there is a roughing mill and a finishing mill at a feed rate of the intermediate strip, if applicable, in the finishing mill of ⁇ 0.15m / s and an outfeed speed in the last scaffolding of the finishing train from ⁇ 16m / s.
- the term solidification thickness refers to the thickness of the Stranges understood when he is completely frozen. That is, the solidification thickness can be smaller than the initial mold thickness, namely if - how it proposes claim 2 - a strand thickness reduction is carried out. It is in Area of the continuous casting machine, a reduction in strand thickness of up to 50% to make. At the same time, a concave strand guide is recommended, which leads to a Slab with a maximum of 2% crowning, based on the solidification thickness, leads.
- the continuous casting machine as a single-strand casting machine is provided with an oscillating funnel-shaped casting mold, wherein the mold its funnel shape at least by concave curvature of the broad sides of the mold in the upper half of the mold. Furthermore, the continuous casting machine be formed with a metallurgical length of ⁇ 50m. All in all there is a combination of plant units from conventional hot strip mills with thin slab technology.
- Figure 1 shows schematically an endless casting and rolling plant with a Single-strand casting machine 1 and a rolling mill directly connected to it 2, which in the exemplary embodiment shown consist of a two-stand (possibly also three-stand) roughing mill 3 and a finishing mill 4 composed.
- This casting and rolling system produces a hot strip 5 from one minimum thickness from 1 to 0.6 mm - also as a cold strip substitute - with minimal Investment and production costs.
- Process parameters is achieved that the continuous casting and rolling components almost have the same capacity and are in balance.
- the capacity balance according to the proposed parameters between the single-strand casting machine and the rolling mill is based on a medium casting and rolling width of 1300 mm.
- the single-strand casting machine 1 has an oscillating casting mold 6, the Broad sides 7a, b for creating a funnel shape in the upper half of the mold 6 are concave.
- the mold is with an electromagnetic device 8 or electromagnetic brake to prevent steel turbulence in the Provide mold.
- strand 9 is subjected to a strand thickness reduction - here indicated by 10 - to check the internal quality of the strand.
- the strand thickness is reduced by means of hydraulically adjustable rollers and / or Segments.
- the strand guide is concave, which leads to a strand with a maximum 2% crowning at the system outlet of the continuous casting machine, based on the solidification thickness, leads - marked here with 11.
- the reduced-thickness strand 9 enters rolling mill 1 and passes through a descaling device 12.
- the descaling device 12 is arranged immediately before the roughing mill 3.
- the intermediate rolled product 5a then passes through a continuous equalization furnace 13. Alternatively, it can also be an isolated roller table.
- the intermediate rolled product in a - here - 6-stand mill 15 finish-rolled. It is then cut using scissors 16 and coiled free selectable coil weights from one of at least one reel device - here two (17, 18) - existing winding station 19 wound up.
- the belt still runs between the finishing stand 15 and the winding station 19 a cooling section 20.
- the finishing stand or the scissors 16 the belt by means of a reel device provided here 21 to coil. It is advisable to have emergency scissors in front of finishing mill 4 22 provided.
- the proposed continuous casting and rolling system should have all the advantages have a separate system.
- a pair of scissors 23 and a compensating furnace 24 are provided which are in the continuous casting and Rolling line are integrated and can be used if necessary.
- the Compensating furnace can be with or without a transverse transport 25 (indicated here by arrows) provided for buffering slabs produced by the transverse shear 23 his.
- the leveling furnace is preferably equipped with rollers.
- the invention lies in the combination of process and system parameters capacity balancing between the continuous casting facility and the rolling mill Create maximum productivity.
- Table 5 it becomes clear that a casting roll below the given conditions with a Strand solidification thickness of ⁇ 100 mm and ⁇ 200 mm for the generation from 2 to 3 million tons per year with a minimum of 5 or 6 stands Scaffolding in the finishing mill is possible.
- the tables according to FIGS. 2 and 3 show the casting and rolling data for a hot strip production of 2, 3 and 4 million tons per year for a strip with a minimum thickness of 1 mm and an average strip width of 1,300 mm, i.e. the casting performance (millions Tons per unit of time), the casting speed (v c in m / min) and the metallurgical length (m) of the single-strand casting machine depending on the solidification thickness (Thickness (Th.) In mm, each marked with a certain geometric symbol) or mass per Distance (W. in t / m), the thickness reduction in the roughing mill (Reduction Mill (RM)) with two stands and the rolling speed in the finishing mill (Finish Mill (FM)).
- the table in FIG. 4 specifies in particular the speed at the exit from the roughing train (v R ex, RM ) and the speed at the exit from the finishing mill (v R ex, FM ) as a function of the solidification thickness.
- FIGS. 5a to 5d show the ratios of the casting speed in m / min, the metallurgical length in m, the feed speed into the finishing train in m / s as well as the exit speed from the finishing train in m / s each Casting output in million tons of hot strip per year and depending on the Solidification thickness of the strand (100, 150, 200 and 250 mm).
- Figure 5a are as Limit for the casting speed 8m / min specified. Overall it can be seen that with increasing casting performance the annual production consequently increases, the casting speed being higher with thinner solidification thicknesses can.
