Definitions
- the invention relates to a method for guiding strands of a continuously pouring Continuous casting plant, in particular a plant for producing thin slabs from steel, with a mold and a strand guide frame provided with a cooling device, wherein the strand is held in shape by a gaseous medium and guided in the direction of the strand pull-out and cooled, and a device for performing the method.
- Such a method or the device is known from AU-A-49917.
- the strand routing in slab or ingot continuous casting plants becomes regular performed by rollers arranged below the mold. As far as they have these roles are uncooled, a minimum diameter of about 100 mm and, insofar as they are one Have internal cooling, a diameter of at least about 140 mm. In slab caster, that can assume a slab width of up to 3.5 m come split Rollers with intermediate bearings are used.
- Spray cooling is regularly used when using uncooled rollers. This The type of spray cooling harbors the risk of uncontrolled cooling of the strand Strand surface cracks can result.
- the roll diameter in connection with the strand width determines the distance between the individual roles to each other.
- This roller distance which is a characteristic variable for strand support or strand bulge is to be considered directly the strand quality.
- the bulging of a strand depends on the casting speed and the distance between the rollers. While standard slabs with a thickness of about 200 mm with a maximum speed of 2.2 m / min. is poured. become Thin slabs with a thickness of about 50 mm with a speed of 6 m / min. poured, with speeds of 8 m / min. be aimed for.
- the strand shell is made of thin slabs before it emerges the mold until it solidifies compared to strand shells for standard slabs is significantly hotter in the same metallurgical location.
- the pouring thickness is less and the tendency to bulge and thus to deform of the strand in an uncontrollable manner.
- plates are also known as strand guide elements.
- EP 0 107 563 A1 proposes a grid that is below the Mold is arranged and through the free space a cooling medium, for. B. splash water, is sprayed against the strand surface.
- the invention has therefore set itself the goal of simple strand management to create even for high casting speeds, with structurally simple means enable the production of strands of high surface quality with low wear.
- the invention achieves this goal by the characterizing features of the method claim 1 and the device claim 5.
- the strand slides on a gas cushion after leaving the mold, which is placed between plate segments and the strand and becomes its heat indirectly touching it by absorbing the radiant heat from the strand Withdrawn cooling plates.
- Nitrogen is preferably used as the gaseous medium to be used by the appropriate construction of the plate segments on the strand facing wall keeps it in shape, leads in the strand discharge direction and in addition to absorb the indirect heat (radiation) through the cooling plates the flowing gas is cooled.
- the strand guide plate segments on the No work to carry (weight) of the strand Furthermore change the specific work in the respective segments or via the metallurgical length from the mold exit to the end of the strand guide.
- the strand is additionally connected via mechanical means (here essentially Continuous casting rolls) defined by the continuous stand at a predeterminable speed emotional.
- the rollers can transport or the desired casting speed and / or support and take over or ensure the bending and straightening processes.
- the speed at the end of the Continuous casting stand arranged role used here since the strand is completely solidified.
- the drive energies via the gas flow and the continuous casting rollers are arbitrary tunable.
- the Conveyed strand by the gas flow and by the continuous casting rollers at its speed braked to the target speed.
- the plate segments essentially consist of a hollow body through which a Cooling medium is preferably passed suction.
- a network of distribution lines is provided on the side inclined through the line which is a gas, e.g. Nitrogen.
- the distribution lines are section by section interconnected and connected to a gas production station via manifolds.
- the individual nozzle openings of the distribution lines can vary be trained. Their distribution will also be according to the amount of work adapted to their location in the strand guide. For example, the number of nozzles and / or the sum of the nozzle openings in the segment over a metallurgical length and width can be functionally changed to at different geometric locations to do different work with the same pressure supply.
- This distribution of Nozzles in the sense of different performances at the same pressure e.g. per printing system (Segment plate, pneumatic cushion) can be used both transversely and lengthways Casting direction is available. Also, a segment can be different from each other independent pneumatic systems.
- the nozzles or a part of the nozzles be pointed To give inclination to the casting direction to support the promotion of the strand.
- This support of the strand conveyance provides the continuous casting speed safe and supports and simplifies the workload between the plate segments arranged pairs of rollers.
- the plate segments have at least in Edge area a distance from the strand surface, which is a defined leakage of the Gases between the strand and the lip arranged at least in the edge region allows.
- the plate segments are on actuators, for example piston-cylinder units, connected with which the distance of plate segment and strand and thus the Gas leakage can be predetermined.
- the wall inclined to the strand is in its design and in the material Built in such a way that it can dissipate a maximum of radiant heat.
- copper with a relatively small wall thickness to the cooling water arranged in the cooling box of the plate segment absorb the heat.
- the wall thickness of the strand inclined wall of the plate segments varies in such a way that the Thickness decreases towards the main plate axis.
- the one facing the strand can also Wall of the segment with a wear-resistant protective layer, such as. B. Nickel and / or chrome coated.
- the plate segment is constructed from tubes that are meandering are arranged and on the contact lines of the distribution lines for the supply of the gas are introduced.
- the pipeline Through the pipeline there is the possibility of cooling water perform at high speed and thus the highest possible amount to dissipate radiant heat from the strand.
- the Line inclined wall of the plate segments in the conveying direction of the line to be concave.
- the degree of concavity of the wall can be on one start concave mold and in the first segment over all segments of the strand guide be reduced, e.g. to a low concavity or flat surface up to End of the strand guide scaffold, or up to the solidification of the strand.
- a parallel slab or a slab with the desired one concave profile can be created.
- the pneumatic working profile can also extend across the segment width For example, different hole thicknesses can be specified. So it is e.g. advantageous, to build up less pneumatic work in the middle of the plate segment, to do justice to the membrane effect of the strand in the middle. On the edge of the strand, i.e. in the edge area, the strand is more dimensionally stable than in the middle.
- the pneumatic work introduced can be carried out at given strip thicknesses reduced by opening or closing the plate segments in the same gas pressure or be enlarged, i.e. the distance between the plate segments and the strand is varied.
- This pneumatic work value can be due to the distance between the plate segment parts specified on the top or bottom and for a given slab thickness become.
- the strand with a desired The casting speed is conveyed pneumatically by the continuous casting machine.
- the motors of the continuous casters take care of ensuring the exact Target casting speed through additional work, either promotion (Motor operation) or the rollers run in generator operation and brake the slab to the desired target casting speed. If the motor current rises above the specified one Beyond limits, the base speed is corrected pneumatically.

- Act in the present case it is an arcuate continuous caster for producing slabs B, in the case of the strand 12 from the vertically aligned mold, with its strand shell W enclosing the swamp S is conveyed out.
