Definitions
- the invention relates to a device and a method for secondary cooling in a continuous casting plant and a continuous casting plant with such a device.
- a device and a method for secondary cooling in a continuous casting plant and a continuous casting plant with such a device In this case, between adjacent casting in the casting rollers, which lead a strand, arranged nozzles that apply coolant to the strand.
- the subsequent cooling and solidification takes place in the so-called secondary cooling zone, which is usually located between the roller guide or the strand guide.
- DE 24 01 263 shows a cooling system for a secondary cooling section of a continuous casting, are arranged in the casting between the rollers spray water nozzles.
- the area of the strand which the nozzles cover for cooling can be enlarged or reduced by means of various apertures.
- This system is intended to cool the slab edges less than the slab center.
- a disadvantage of this system that the nozzles are fixedly arranged with respect to the direction parallel to the longitudinal axis of the rollers. As a result, the system can no longer ensure adequate cooling when an asymmetric slab pattern occurs in the strand guide.
- the system does not allow cooling of different strands in multi-strand operation. The effectiveness of the cooling and the cooling result deteriorate greatly as the width of the strands varies. If a narrow strand is to be cooled, then a large part of the cooling water must be "hidden" whereby it is lost for cooling and has to be returned or removed.
- DE 30 39 443 discloses a system for secondary cooling in a continuous casting plant having two opposing, fixedly mounted adjusting levers, which are connected by a push rod in the manner of an anti-parallel crank with opposite motion transmission, wherein the hinged to the adjusting levers are guided together parallel to the strand surface.
- This construction is also mounted between two rollers adjacent to the casting direction.
- a disadvantage of this cooling device is its complicated and expensive construction. Moreover, this device does not allow due to their structural conditions to compensate for an asymmetric strand profile. The strand edge overspray can not be avoided and central portions of the strand may not be adequately cooled.
- DE 25 07 971 shows a further, mechanically very complicated construction for secondary cooling between two adjacent casting in the casting, in which a metal linkage, which can be deployed and unfolds, splash water nozzles carries.
- This invention has similar disadvantages as the DE 30 39 443 on.
- the publication JP59153558 A shows a device with three nozzles for cooling a slab.
- a first nozzle is arranged centrally above the slab and relative to the surface thereof only vertically or vertically adjustable, but not adjustable parallel to the surface of the slab.
- Two nozzles arranged next to the first nozzle are first moved horizontally or transversely and then vertically or perpendicular to the slab. The spray areas of the nozzles do not overlap according to this device.
- the invention disclosed below comprises a cooling device for secondary cooling a strand in a continuous casting plant, the cooling device comprising: at least two nozzles for spraying a coolant onto the surface of the strand between two rolls adjacent to one another in the casting direction the continuous casting machine, in particular the strand guide and a displacement and positioning device for moving and positioning the at least two nozzles independently of one another parallel to the longitudinal axis of the rollers in dependence on at least one casting parameter, wherein the displacement and positioning device is designed such that the vertical distance of the nozzles remains constant from the surface of the strand.
- the cooling device comprises a control or regulating device for automatic displacement and positioning of the nozzles by means of the displacement and positioning device as an actuator in response to the Gelloparameter and - optionally - additionally in response on the spray angle or the spray pattern of the nozzles.
- the displacement and positioning device is in the form of two linear guides with at least one associated adjusting drive, wherein the guides between the two adjacent rollers parallel to the rollers, but offset in the casting direction to each other, and at each of the two guides at least one of Nozzle is slidably mounted, so that the nozzles arranged offset in the casting direction in the longitudinal direction of the rollers are positioned so that their spray patterns - seen in the casting direction - only in the region of the still liquid core of the strand but not at the edge regions overlap.
- the system requires very little space in this direction. Furthermore, it is achieved by the independent adjustment of the nozzles that strands can be optimally cooled, ie, for example, that even with an asymmetric slab profile, the nozzles can be adjusted so that they cool only a desired central region of the strand. For each strand run a strand edge over-injection can be avoided.
- the system can be used for multi-strand operation without any modification and thus efficiently cool individual adjacent strands.
- the spray can by adjustment The nozzles are concentrated on the strand centers, whereby an intensive cooling of the strand center is made possible.

- the cooling device comprises first sensors for detecting the respective current position of the individual nozzles and second sensors for detecting the casting parameters, preferably in each case in real time.
- first sensors for detecting the respective current position of the individual nozzles
- second sensors for detecting the casting parameters, preferably in each case in real time.
- the second sensors are displacement or position sensors for the current detection of the position of the strand and the edge regions of the strand.
- the at least one adjustment drive is electrically, pneumatically or hydraulically designed.

It is of course also possible, depending on the application, not to spray the edges of the strand 1 in order to avoid strand edge over-molding or to cool the strand center more intensively.
- FIG. 2a shows FIG. 2b in that the spray patterns B 'of both nozzles 3 do not overlap.
