Definitions
- the invention relates to a device for keeping cold strip in the outlet of rolling mills with means for repelling liquid rolling media in the area of the strip outlet and / or for keeping liquid splashing on the strip surfaces, these u. a. to form a functional unit, means consist of installed and installed bulkheads and movable bulkheads, a roll barrel blow-off device, a roll barrel gap seal and an extractor fan.
- the preferred quality requirements that manufacturers place on the "cold strip” product also include dryness of the strip in the outlet of cold rolling and strip lines in order to avoid surface defects, such as stains, for further processing of the strip ,
- DE 44 22 422 A1 discloses a device for contactless sealing of the gap between a partition and a work roll in the outlet of a roll stand, a partition element with a gap nozzle being approximately tangential to the surface of the work roll and at a relatively small distance from it Rolling strip is arranged.
- the partitioning element On its front side, the partitioning element has an approximately tangential and at a small distance from the roller surface arranged, tapered end part, which is arranged and designed such that an injector-like flow channel is formed which widens in cross section between the latter and the roller surface.
- EP 0 765 696 B1 proposes combining various means for repelling and removing liquid rolling media to form a functional unit.
- the damp and wet roller area is sealed off from the finished rolled strip by a permanently installed partition, one part of which is connected above the strip run to the scaffolding platform and the other part below the strip run to the base plate.
- An additional and out Movable parts existing movable part ensures further partitioning of the wet and wet roll area against the finished rolled strip, but enables the rolls to be advantageously accessible due to the movement of the parts, for example when carrying out a roll change.
- these moving parts implement the function of a belt deflector and / or a means for belt transfer.
- the movable parts designed as stops can be either mechanically fixed or adjustable depending on the roll barrel.
- the object of the invention is to further develop the device known from EP 0 765 696 B1, known as the so-called DS system (dry-strip system), for keeping cold strip dry, so that it is ensured that the rolled strip is free of drips "DS-System” leaves and there is only a residual oil quantity determined by the emulsion composition and the rolling process on the rolling belt.
- DS system dry-strip system
- the device as a whole consists of the interacting system parts in the area of the strip outlet:
- the upper band blow-off with fan-operated low-pressure nozzle laterally discharges the emulsion passing through the roll gap next to the rolled strip;
- the upper roll bale blow-off prevents the squeezed emulsion from running down the roll and reaching the finished belt.
- the squeezed emulsion is discharged laterally through the air flow;
- the upper roller bale seal in the form of a slot nozzle using the Coanda effect, the air jet emerging from the slot of the slot nozzle being guided around the curved roller surface, thus sealing the area above the belt deflector without contact against the roller and with it against the finished rolled strip;
- the upper band deflector is designed to be displaceable at an angle of 20 ° to 45 ° and is arranged in such a way that the roller can be changed without any problems;
- the strip channel formed with separate suction below the strip run creates a defined flow around the strip edge after the roll gap.
- the extraction can be fan-operated from a suction trough installed below the belt or with the help of injector nozzles, which are installed in zones below the belt run in a belt guide table.
- the band channel is designed so that it can also be used as a threading aid for the beginning of the band.
- FIG. 1a is an enlarged view of the roll bale gap seal from FIG. 1,
- FIG. 3 air flow paths after a low pressure nozzle in a plan view.
- FIG. 1 shows two support rolls 31, 32, and between these two work rolls 33, 34 with adjustable roll gap 12, omitting the actual roll stand. Above and below the roll strip 10 running out of the roll stand, from left to right in the drawing from the rolls 31, 32, 33, 34 and the rolled strip 10 formed wet wet roll region 11, from which the rolled strip 10 to be shielded.
- this damp-wet roller region 11 is already partially partitioned off from the finished rolled strip 10 by a permanently installed upper partition 1 and a permanently installed lower partition 2.
- These permanently installed partitions 1, 2 are supplemented by movable partitions.
- this supplement is an upper, displaceable strip deflector 3, which contains an integrated fan-operated strip blower 4 with a low-pressure nozzle 7.
- This band blow-off 4 is extended towards the top of the work roll 33 with a slot nozzle 6 to form a roll bale gap seal 5 and is guided close to the work roll 33. Due to the special design of the slot nozzle 6, the remaining gap between the work roll and the slot nozzle 6 is sealed using the "Coanda effect". This effect has the effect that the air jet emerging from the slot nozzle 6 follows the curvature of the curved roller surface of the work roller 33 directly downstream of the slot nozzle 6 and thus suppresses the liquid media adhering to the roller surface.
- This slot nozzle 6 of the roll barrel nip seal 5 can be clearly seen in an enlarged representation, in particular from FIG. 1a.
- a roll barrel blow-off 9 is additionally installed in the upper area of the work roll 33, through which liquid media still adhering to the work roll in the direction of rotation of the work roll 33 and thus from the roll belt 10 be pushed away.
- a suction device 16 is installed beneath the rolled strip 10 to supplement the permanently installed lower partition 2, the front end of which is extended by a lower strip deflector 17 which extends to the lower work roll 34.
- the suction device 16 is designed such that it forms, together with the upper strip deflector 3, a strip channel 15 through which the rolled strip 10 is guided, and which can also be used as a threading aid for the beginning of the rolled strip.
- Part of the suction device 16 is a suction pan 18 with a connected emulsion drain line 19 and an exhaust air line 20.
- the suction device 16 is shown with the resulting air flow directions 21 in a vertical section. Air overpressure prevails above the rolled strip 10, while a vacuum is produced below the rolled strip 10 by the suction of the air.
- the resulting paths of the air streams 21 lead above the rolled strip 10 parallel to the rolled strip edge and along this down into the suction pan 18. Here the air is deflected towards the center of the suction pan 18. The air is then passed further into the exhaust air lines 20, with which the exhaust air is removed from the system.
- the device can preferably cooperate with a roll gap lubrication which is dependent on the bandwidth, specifically regardless of axially displaceable or fixed rolls.
- the invention is not limited to the illustrated embodiment. Individual components and their linkage can be varied as required, but the device is still to be designed such that it reliably prevents moisture in the form of drops or vapor precipitation from falling back onto the rolled strip 10 and thus optimizes the strip quality. What is decisive here is the maintenance of the embodiment according to the invention and forced air flows of the upper band blow-off device 4 and the lower suction device 16, and overall the interaction of the construction elements mentioned.
