Description

1 METHOD AND DEVICE FOR GUIDING STRANDS IN A CONTINUOUS CASTING INSTALLATION BACKGROUND OF THE INVENTION The invention relates to a method for guiding strands in a continuous casting installation, in particular a installation for producing thin steel slabs, having a stationary ingot mold or a moving ingot mold and a strandguidance frame which is provided with a cooling device.
The invention further relates to a device for carrying out the method.
DISCUSSION OF THE PRIOR ART As a rule, strand guidance in continuous casting installations for slabs or blooms is carried out by means of rolls arranged below the ingot mold. If they are uncooled, these rolls have a minium diameter of approximately 100 mm, while if they are internally cooled they have a minimum diameter of approximately 140 mm. In the case of continuous slab casters, which are able to accommodate a slab width of up to 3.5 m, split rolls with intermediate bearings are used.
As a rule, when uncooled rolls are used a spray cooling system is employed. This type of spray cooling 25 system presents a risk of uncontrolled cooling of the strand, which can lead to surface cracks on the strand.
The diameter of the rolls, in conjunction with the strand width, determines the distance between the individual rolls. This roll-to-roll distance, which can be 30 regarded as the characteristic variable for the strand support or the strand bulging, has a direct effect on the quality of the strand. The bulging of a strand is dependent on the casting speed and on the distance between the rolls. While standard slabs of a thickness of approximately 200 mm are cast at a maximum speed of 2.2 m/min, thin slabs with a thickness of approximately 50 mm are cast at a speed of 6 m/mm, and speeds of 8 m/mm are HL\uisa\Keep\speci\17173-97.doc 10/08/99 2 being striven for.
An aggravating factor is that the strand shell of thin slabs is considerably hotter, right from leaving the ingot mold until completely solidified, by comparison with strand shells of standard slabs at the same metallurgical location.
Since the diameter of the rolls and also the distance between the individual rolls cannot be reduced arbitrarily, the tendency toward bulging and hence toward deformation of the strand increases in a manner which can no longer be controlled as casting rates become higher and at the same time the cast thickness falls.
In addition to the strand-guidance rolls, plates are also known as strand-guidance components. For example, EP-0,107,563 Al proposes a grid network which is arranged below the ingot mold and through the free space in which a cooling medium, for example water, is sprayed against the surface of the strand.
i The drawbacks of these components are that high frictional forces occur between the strand and the plates, and moreover there is a risk of quality drawbacks in the form of breakouts and also of deflagration caused by trapped water. Furthermore, high withdrawal forces are required for withdrawing the strand, leading to a high load 25 on the strand shell.
SUMMARY OF THE INVENTION The object of the present invention is therefore 30 to use simples means in order to provide strand guidance 30 even for high casting speeds allowing the production of strands of high surface quality with a low level of wear and employing means of simple designs.
According to a first aspect of the present invention there is provided a method of guiding a strand in a continuous casting installation, having an ingot mold and a strand-guidance frame which is provided with a cooling device, comprising the steps of: H:\Luisa\KeepSpeci\17173-97.doc 10/08/99 3 extracting heat indirectly from the strand after it leaves the ingot mold; holding the strand in shape at least in sections using a gaseous medium; guiding at least sections of the strand in a direction of a strand discharge using the gaseous medium; additionally cooling at least sections of the strand using the gaseous medium; and additionally mechanically moving the strand in a defined manner and at a predeterminable speed through the strand frame so that the strand is either accelerated or decelerated.
According to a second aspect of the present invention there is provided a continuous casting device for producing a strand, comprising: an ingot mold; a strand-guidance frame arranged to following the ingot mold in a casting direction, the strand-guidance frame having rolls bearing against a strand surface, plates 20 provided with bores, and means for cooling the strand surface, the plates being divided into segments, between which the rolls are provided; means for directing a gaseous medium toward for holding the shape of the strand, guiding the strand, and 25 cooling the strand, the gaseous medium directing means .including a network of distribution lines through which ***gaseous medium can be supplied, provided in the plate segments on a side wall inclined toward the strand, the :network of distribution lines being connected to one So another in sections; a gas-conveying station; and collection lines that connect the distribution lines to the gas-conveying station, the plate segments, at least in an edge region, being arranged at a distance from the strand surface so as to allow a defined leakage of the gaseous medium.
H:\Luisa\Keep\speci\17173-97.doc 10/08/99 4 According to the invention, after leaving the ingot mold the strand slides over a cushion of gas which is positioned between plate segments and the strand, and the heat of the strand is extracted indirectly due to the fact that the radiant heat is taken up by cooling plates which are not in contact with the strand. The gaseous medium used is preferably nitrogen, which by means of a suitable design of the plate segments on the wall facing the strand holds the latter in shape and guides it in the strand discharge direction. Furthermore, the flowing gas cools the strand in addition to the cooling plates taking up the indirect heat (radiation).
In a curved installation, the strand is curved through a constant curve over a plurality of bending points of else continuously. The work which is to be done in each case by the gas film from the segment 0 and the following segment comprises: supporting the strand as a function of the weight proportion in a corresponding manner from the 20 location of strand guidance between the vertical and horizontal parts of the cast strand guidance; compensating for the ferrostatic pressure as a function of the vertical distance to the casting level; 25 bending and straightening of the strand; rolling and casting, reduction in the strand thickness during solidification; and conveying the strand.
It should also be taken into account that the 30 strand guidance plate segments do not have to do any work to support (the weight of) the strand on the top side.
Moreover, the specific amounts of work vary in the respective segments and over the metallurgical length from the ingot mold outlet to the end of strand guidance.
The different amounts of work per plate segment are ensured using segment-specific design and/or control of the gaseous medium in pressure times volume. Particular H:\Luisa\Keep\speci\17173-97.doc 10/08/99 5 account is taken here of the dependency of the current shell thickness of the strand. When designing the installation, attention is paid to setting the level of work done pneumatically on the strand such that the strand is guided, conveyed and if desired reduced in terms of its cast thickness but is not deformed in an uncontrolled manner by indentation, that is to say negative bulging.
At the same time, the strand is additionally moved in a defined manner and at a predeterminable speed through the strand frame by mechanical means (in this case essentially continuos casting rolls). The rolls can assist with, perform and ensure the transportation and/or the desired casting speed and/or the bending and straightening processes. The roll arranged at the end of the continuous casting frame is used to ensure the casting speed in a defined manner, since by this stage the stand has completely solidified.
The drive powers introduced via the gas stream and the continuous casting rolls can be matched to one 20 another as desired. In an advantageous configuration of the invention, the strand is conveyed by the gas stream and its speed is decelerated to the desired speed by means of the continuous casting rolls.
The plate segments essentially comprise a hollow 25 body through which a cooling medium is guided, preferably with suction. A network of distribution lines, through which a gas, for example nitrogen, is guided, is provided in the plate segments on the side inclined toward the strand. The distribution lines are connected to one 30 another in sections and via collection lines are connected to a gas-conveying station. The individual nozzle orifices of the distribution lines may be formed differently. Their distribution may also be adapted in accordance with the work done at their location in the strand guidance. Thus it is possible, for example, for the number of nozzles and/or the sum of the nozzle orifices in the segment to be changed in functional terms over a metallurgical length and H;\Luisa\Keep\Speci\17173-97.doc 10/08/99 6 width, in order to do different amounts of work at different geometric location while supplying the same pressure. This distribution of the nozzles in the sense of different outputs at constant pressure, e.g. per pressure system (segment plate, pneumatic cushion), can be present both transversely and longitudinally with respect to the casting direction. It is also possible for a segment to be connected to different, mutually independent pneumatic systems.
Furthermore, it is proposed to provide the nozzles or some of the nozzles, with an acute angle of inclination with respect to the casting direction, in order to assist with conveying the strand. This assistance with strand conveying fixes the continuous casting speed and assists with and simplifies the workdone by the pairs of rolls arranged between the plate segments. At least in the edge region, the plate segments are at a distance from the strand surface allowing defined leakage of the gas between the strand and the lip arranged at least in the edge 20 region.
The plate segments are connected to actuators, for example piston-cylinder units, by means of which the distance between plate segment and strand, and hence the gas leakage, can be set in a predeterminable manner.
25 The wall which is inclined toward the strand is .designed in terms of its form and material in such a manner that it is able to dissipate the maximum possible amount of radiant heat. It is preferred here to use copper of a relatively low wall thickness, in order to take up the heat by means of the cooling water arranged in the cooling chamber of the plate segment.
In a further embodiment of the invention, the wall thickness of that wall of the plate segments which is inclined toward the strand varies, specifically in such a manner that the thickness decreases towards the principal axis of the plate. In addition, that wall of the segment which faces the strand may be coated with a wear-resistance H:\Luisa\Keep\Speci\1713-97.doc 10/08/99 7 protective layer, such as for example nickel and/or chromium.
In one embodiment, the plate segment is composed of pipes, which are arranged in a meandering form. The distribution lines for supplying the gas are introduced at the lines where these pipes are in contact with one another. The pipeline makes it possible to convey cooling water at high speed and hence to dissipate as much radiant heat as possible from the strand.
In order to guarantee that the strand runs centrally, it is proposed for that wall of the plate segments which is inclined toward the strand to be designed concavely in the direction of travel of the strand. The extent of the concavity of the wall may in this case begin at a concave ingot mold and be reduced in the first segment over all the segments of the strand guidance, for example to a low level of concavity or even a planar surface by the end of the strand-guidance frame or by the point at which S• the strand has completely solidified. In this way, it is S 20 possible to produce a parallel slab or a slab having a desired concave section.
Furthermore, the profile of the work performed pneumatically over the segment width can be predetermined, for example by means of different hole thicknesses. Thus 25 it is advantageous for example, to build up a lower lever of pneumatic work in the center of the plate segment, in order to cope with the membrane effect of the strand in its center. At the edge of the strand, i.e. in the peripheral region, the strand is more dimensionally stable that in its center.
Moreover, for predetermined strip thickness the amount of work done pneumatically can be reduced or increased for the same gas pressure by opening or closing the plate segments, i.e. by varying the distance between the plate segments and the strand. This level of work done pneumatically can be predetermined by means of the distance of the plate segments on the top and bottom sides, given a H:\Luisa\Keep\Speci\17173-97.doc 10/08/99 8 predetermined slab thickness.
Essentially, in the device according to the invention the strand is conveyed pneumatically through the continuous casting machine at a desired casting speed. The motors of the continuous casting rolls ensure the precise desired casting speed by means of additional work either conveyance (motor operation) or the rolls run in a generator mode and decelerate the slab to the desired casting speed. If the motor current rises above predetermined limits, the basic speed is corrected pneumatically.
The proposed method and device achieve the following results: the strand is not subject to any bulging and hence deformation, even at high casting speeds of up to 10 m/min, the strand does not require any direct water cooling and hence exhibits mineral energy loose, if inert gas is used, scaling of the strand is 20 avoided, progressive bending and straightening with the lowest possible area-specific deformation is possible, progressive casting and rolling, and also a 25 reduction in the thickness of the strand during its freezing, are possible, and there are no rotating mechanical components, which has the advantage that: consequently wear to the machine is minimal, 30 and a high casting reliability is achieved by comparison with the so-called grids which are cooled with spray water, and there are no mechanical limits on the conveyance of the strand, as is the case, for example, with continuous'casting strandguidance frames comprising rolls, HI\Luisa\Keep\Speci\17173-97.doc 10/08/99 9 particularly in the case of very wide, quickcasting slab installations, in particular thin slab installations.
