Definitions
- the invention relates to a device for removing liquid from the surface of a strip conveyed from a strip processing machine, in particular a roll stand.
- Devices of this type are required, in particular to remove oil and emulsion residues from high-speed metallic rolled strips, which were applied to the strip as lubricants during the rolling process. If this removal is not carried out to a sufficient extent, the liquid residues remaining when the tape is reeled into a tape bundle between the individual turns act like a lubricating film, and the tape can tend to telescope, i.e. shift in the direction of the reel axis when reeling. In addition, very low amounts of lubricant residues, based on the surface of the rolled strip, are usually prescribed for the further processing of the strips.
- the invention has for its object to provide a device with which the disadvantages described are avoided.
- a gas jet that is optimally designed in terms of flow technology is used to adequately remove the liquid film from the belt surface generates the necessary wall shear stress on the belt and this liquid film pushed on by the gas jet is sucked off uniformly over the belt width with a suction gap arranged in front of the slot jet when viewed in the direction of belt travel.
- the suction capacity of the gas jet is matched to the gas flow blown out with the slot nozzle in such a way that at least this volume flow, which also contains the peeled lubricant, is detected and removed by the suction gap. In this way it is avoided that blown off lubricant collects on the roll stand construction or is accumulated on the belt in front of the blow-off device and can get back onto the belt that has already been blown off.
- the invention is based on the knowledge that the main reason for the unsatisfactory removal of the lubricant residues from the belt by blowing off in the prior art is that the impact velocity achieved with the nozzles on the belt and thus the wall shear stress acting on the belt surface due to flow movement increases is low.
- the ratio of the nozzle spacing to the nozzle slot width is considerably greater than the core jet length, or, in the case of overexpandable compressible jets, greater than the jet length in which high-speed zones, so-called supersonic drums, are created.
- the ratio of the distance h of the nozzle from the moving belt to the width s of the gas jet is in the range from 2 to 10. This ensures that the gas jet actually achieves the highest possible impact velocity for a specific inflow situation to the nozzle becomes.
- the invention can also be used from an economic point of view achieve a satisfactory result.
- the inventive configuration and arrangement of the slot jet nozzle makes it possible to achieve the speeds of 300 m / s or more required for removing rolling oil from a metal strip during normal operation of the blow-off nozzle with air. In the invention, this can be achieved with comparatively low pressures of only a maximum of only 2 bar, while in known nozzles an air pressure of 4-6 bar is not yet sufficient to clean the metal strip.
- the invention can be implemented with or without squeeze rollers arranged upstream in the tape running direction. If there are no squeezing rollers or the device for removing rolling oil or rolling emulsion has to be arranged at a greater distance from the squeezing rollers, two slot nozzles are preferably inclined relative to one another above and possibly below the belt. The suction slot is then between the two slot nozzles. In this case, the suction must be dimensioned such that the gas streams inflated onto the belt by both slot nozzles, including the liquid, are captured by the suction.
- the required impact velocity of the gas flowing out of the nozzle and thus the required supply pressure of the slot nozzles depends on the properties of the liquids to be removed from the belt. With a relatively warm belt and roller emulsion, relatively low impact speeds in the range of approximately Mach 0.3 are sufficient, corresponding to approximately 100 m / s. In the case of higher-viscosity rolling oils, experience has shown that arrival speeds at the strip surface around Mach 1 corresponding to approx. 300 m / s are required for medium to high rolling speeds.
- the nozzle gap is designed in the manner of a Lavall nozzle with a narrowest cross section and a subsequent expansion part shaped according to gas-dynamic aspects, which allows the flow to be accelerated to speeds higher than the speed of sound.
- FIG. 1 there is a squeezing roller 1, 2 above and below the belt B. So that there is no rolling effect, the axes 1a, 2a of these squeezing rollers 1, 2 are slightly offset from one another in the strip running direction.
- a slot jet nozzle 3 which directs a gas jet at an angle ⁇ between 45 ° and 90 ° against the direction of travel L of the tape B onto the tape surface.
- the slot jet nozzle 3 is arranged at a distance h from the surface of the belt B.
- the gas jet emerging from it has the same gap width s as the slot of the nozzle 3 itself in the case of a non-widened nozzle opening in the region of the nozzle outlet opening.
- a suction gap 4 is in the case shown on the one Page formed by the correspondingly shaped nozzle body 5 and on the other side by the squeeze roller 1.
- the underside 5a of the nozzle body 5 has a step 5b in the area between the nozzle gap 3a and the suction gap 4, which ensures that the nozzle body 5 does not influence the speed field of the gas jet. In this way, the full impact velocity of the gas jet has an effect on the wall shear stress arising on the belt surface.
- the slot nozzle 3 is supplied by a supply channel 5c which extends over the entire bandwidth.
- the suction gap 4 is connected by a correspondingly narrow rectangular channel over the entire width of the band B to a suction swirl tube 6.
- the volume flow to be extracted is expediently discharged from the suction swirl tube 6 to both sides, that is to say both to the front and to the rear in the illustration. With smaller working widths, the one-sided derivation of the suction flow can also be sufficient.
- the flow arrows shown illustrate the effect of the suction swirl tube 6.
- the suction gap 4 is - in deviation from the different proportions of the schematic drawing for reasons of illustration - dimensioned much larger than the nozzle gap 3a, because on the one hand the suction speed is significantly lower than the blow-out speed from the nozzle gap 3a and on the other hand the volume flow to be suctioned is larger by the proportion must, in addition to the volume flow emerging from the nozzle gap, for example is sucked in at the edges of the band B.
- the slot nozzle 3 can have different shapes. In the exemplary embodiment shown enlarged in FIG. 2, it has an extension part 3b in the nozzle gap 3a, similar to a Lavall nozzle. In this nozzle, the thickness of the slit jet is equal to the gap width s at the narrowest point of the slit nozzle 3.
- the extension part 3b means that the flow is accelerated beyond the speed of sound and strikes the belt B at an even higher arrival speed. In this way, the wiping effect of the gas jet emerging from the nozzle 3 can be increased even further with relatively simple means, namely only by an appropriate design of the nozzle gap 3a, without the nozzle pressure having to be increased in an uneconomical manner.
