Definitions
- the invention relates to a method for producing a cast steel strip of a preferably H exertrisshaveen or hot brittle steel quality with a strip casting, and a strip casting plant for performing this method.
- the strip caster is preferably a two-roll caster with two casting rolls arranged with their axes of rotation in a horizontal plane.
- carbon steels with a low C content C content ⁇ 0.20% by weight, in particular C ⁇ 0.8%) and austenitic steel grades
- carbon steels tend to have higher C contents, electrical steels, and in some cases also ferritic and martensitic ones Steel grades to hot and hot crack susceptibility in temperature ranges above about 1150 - 1250 0 C upwards.
- the steel strip guided over a quarter-circle arc along one of the casting rolls is shaped by a work roll which can be set against the casting rolls.
- This occurring tensile forces cause up to the Band Struktursquerrough retroactive, usually fluctuating tensile stresses in the steel strip and thereby promote the hot cracking.
- the invention aims to avoid these disadvantages and difficulties and has as its object to propose a method for producing a cast steel strip of a preferably H exertrissaten steel quality and a strip casting plant for implementing this method, wherein the cast steel strip largely free from the band forming cross section to the substantially horizontal transport device by acting on the steel strip Bandanpress- or strip deformation forces (eg by thickness reductions, driver) is performed.
- This object is achieved by a method of the type described above in that the cast steel strip is guided during its transport movement along the lateral surface of one of the two casting rolls without local application of contact forces or the band thickness influencing deformation forces in a transport channel and in this transport channel a strip cooling in a range of 15 K / s to 200 K / s takes place.
- the most favorable belt cooling speed is in a range of 15 K / s to 100 K / s.
- This temperature zone is depending on the to be cast steel quality above 1150 0 C to 1250 0 C, in particular between the ZST temperature (zero strength temperature) and the ZDT temperature (zero ductility temperature), thus in a temperature range above and each below the Soiidustemperatur.
- a particularly gentle tape guide is achieved when the cast steel strip is guided in contact with the contact surface of one of the two casting rolls from a vertical casting direction in a substantially horizontal transport direction.
- the cast steel strip during its transport movement along one of the lateral surfaces of G clothwaizen in an atmosphere with respect to air reduced oxygen content or in a largely oxygen-free inert gas atmosphere is performed.
- the oxygen content of the atmosphere is adjusted to less than 8% oxygen, preferably to less than 1% oxygen.
- the cast steel strip after passing through the transport channel and the translational Wegbelie from the lateral surface of the casting roll over a distance of at least 1 m, preferably more than 2 m, is guided substantially horizontally on a transport device.
- band tensile forces from the weight forces of a downstream sling, a belt driver or reaction forces from a rolling stand against the belt transport direction are steadily reduced, so that the steel belt leaves the transport channel in the region of the lower vertex of the casting roll largely free of unwanted extraneous stresses.
- the cast steel strip after a substantially horizontal transport movement forms a belt loop and from this belt loop, a retro-acting strip tension is introduced into the cast steel strip.
- a stable tape guide from the band forming cross section to the belt loop and on the other hand a decoupling of the casting process of treatment steps in downstream belt treatment facilities is achieved.
- a strip tension in the cast steel strip preferably in a region of the lower vertex of the casting roll, controlled or regulated by the weight of the belt loop.
- the dead weight of the belt loop is determined by a position measurement of the belt loop and used as a control variable.
- the strip tension in the cast steel strip preferably in a region of the lower apex of the casting roll, can be selectively influenced by influencing the friction and velocity relationships between the steel strip and the transport device.
- this can be achieved by introducing on the cast steel strip during a substantially horizontal transport movement on a belt transport means by applying a clamping force to the casting roll back-acting tape tension or tape compressive stresses in the steel strip and this clamping force along a path portion lying in the transport direction of the steel strip end the transport is applied.
- the strip tension in the cast steel strip is adjusted by applying the Kemmkraft and used as a control variable. An interaction of several control variables is possible.
- Particularly stable conditions in the tape guide can be achieved if the strip tension is set in the region of the lower vertex of the casting roll to a value at which the steel strip rests on the casting roll substantially slip-free over substantially the entire quarter circle.
- the strip tension in the lower vertex should in this case be kept so low that only a band flutter is prevented in the transport channel, but beyond no significant additional Bandzug technique should work back into the Band Struktursquerites.
- the average band cross-section temperature at the end of a first substantially horizontal transport movement of the metal strip is 60 0 C to 25O 0 C lower than in Banding cross section, that is, the range of hot brittleness is at this point already substantially exceeded or overcome.
- this substantially horizontal transport movement of the steel strip may include deviations of +/- 15 ° to the horizontal.
- the cast steel strip is subjected before winding in the band reel an at least one-stage reduction in strip thickness in an in-line rolling process.
- a cold strip preferably in opposite direction to the tape transport direction of the cast strip, introduced into the strip casting, which closes the Band Struktursquerrough between the casting rolls and which in the tape transport direction up to a tape transport means on a substantially horizontal aligned transport device or extends over the ski pit where it, preferably with a dividing shear, is separated from the cast steel strip.

- the steel strip on the other hand, can assume a slight, conforming contact with the surface of the casting roll, so that a sufficient cooling of the steel strip by contact heat transfer is achieved.
- the clear width of the transport channel is thus slightly larger than the thickness of the cast steel strip. Due to the different thermal load of the two cooperating casting rolls they are equipped with separate controlled coolant circuits. Thus, substantially the same thermal conditions for the formation of equally thick strand shells are achieved at both G confusewalzenmänteln.
- the transport channel for the cast steel strip is disposed within an isolation chamber to maintain a predetermined atmosphere.

- the transport device comprises driven rollers or roller pairs.
- the metal strip has already cooled down to such an extent that the metal strip can be exposed to a sufficient contact pressure without the risk of tearing or an increased risk of cracking on the strip surface.
- the substantially horizontally oriented transport device includes a preferably designed as a Schiingengrube tape storage.
- the lead-in area in the strip store and the exit area from the strip store are designed in such a way that an asymmetrical loop of the strip is produced in the strip store. This is accomplished by having the tape store include an entry area into the tape store and a run-out area from the tape store, and the exit area from the tape store is lowered from the run-in area to the tape store.
- a swing-in and swing-bridging chute is arranged, which ensures that when casting without cold strip, the leading edge of the cast steel strip safely overcomes the Schiingengrube means of gravity support on the swung-bridging chute.
- a belt steering device assigned. If required, a temperature compensation device is additionally arranged upstream of the first rolling stand.
- a continuous or segmented insulating chamber enclosing the transport path of the steel strip is arranged between the casting rolls and the first rolling mill stand.
