Definitions

  • the invention relates to a method for cleaning and / or descaling a slab or a pre-strip by means of a scale washer, the scale washer having at least one nozzle through which pressurized water is applied to the surface of the slab or the pre-strip.
  • the invention also relates to a scale washer.
  • Scale washers are required for the clean removal of the primary or secondary scale, with water being applied to the slab to be cleaned with a sufficiently high water pressure in a generic scale washer.
  • the energy consumption of a scale washer is considerable.
  • the energy consumption can be up to 4.5 MW.
  • a maximum water pressure of, for example, 380 bar is used.
  • the reduction in energy consumption goes hand in hand with a drop in the water pressure, so that the descaling or cleaning result then decreases in quality.
  • Scale washers in various designs are from the DE 693 14 275 T2 , from the WO 2009/056712 A2 , from the JP 59 076 615 A and from the JP 2010 247 228 A known.
  • the water is applied to the surface of the slab or the rolling stock through a number of juxtaposed nozzles.
  • Such systems have, for example, about 50 juxtaposed nozzles per bar.
  • the US patent U.S. 4,617,815 discloses a method for cleaning and / or descaling a slab or a pre-strip by means of a scale washer, the scale washer having at least one rectangular nozzle through which pressurized water is applied to the surface of the slab or the pre-strip.
  • the invention is therefore based on the object of proposing a method of the type mentioned at the beginning and a scale washer with which a good descaling or cleaning result can be achieved, but at the same time requiring significantly less energy. Furthermore, the temperature losses of the slab or the pre-strip should be reduced.
  • the outlet of the nozzle in the direction normal to the surface of the slab or the pre-strip is designed to be rectangular (rectangular nozzle) or slot-shaped with at least some sections of an arcuate course, so that the water over the entire width of the slab or sliver is applied as a continuous strip-shaped jet, the width of the outlet of the nozzle in the conveying direction of the slab or sliver is selected between 0.3 mm and 0.8 mm, the water of the nozzle with a pressure between 5 bar and 50 bar is supplied and wherein the
  • Distance between the outlet of the nozzle and the surface of the slab or of the pre-strip between 8 mm and 50 mm, preferably between 8 mm and 35 mm, is selected.
  • the width of the outlet of the nozzle in the conveying direction of the slab or of the pre-strip is preferably selected between 0.3 mm and 0.8 mm.
  • the water is preferably fed to the nozzle at a pressure between 10 bar and 40 bar, in particular between 15 bar and 35 bar.
  • the distance between the outlet of the nozzle and the surface of the slab or of the pre-strip is preferably selected between 10 mm and 30 mm, in particular between 15 mm and 20 mm.
  • the flow conditions at the outlet of the rectangular nozzle are designed or dimensioned in such a way that a compact, relatively smooth jet with a high water outlet speed is created there.
  • the fact that the water jet does not spread across the conveying direction with the rectangular nozzle compared with a conventional flat jet nozzle causes high impact and thus a good, even descaling result despite the low pressure.
  • the strip-shaped beam is preferably fixed at an angle between 0 ° and 30 °, preferably between 15 ° and 25 °, to the direction normal to the surface of the slab or the pre-strip against the conveying direction of the slab or the pre-strip, or is adjustable in the aforementioned angular range executed.
  • the alignment of the jet can be optimally set in the specified angular range from 0 ° to 30 ° depending on the drainage conditions of the water, the space conditions or the slab dimensions become. Alternatively, it is also possible to adjust the angle with an adjusting element depending on the above conditions. On the underside of the slab or slab, an angle of 0 ° can also be advantageous in order to maximize the applied impulse (impact), for example.
  • a further development provides that the boundary edges of nozzle plates, which define the outlet of the nozzle, are set to different distances from the surface of the slab or the pre-strip.
  • the proposed scale washer for cleaning and / or descaling a slab or a pre-strip is characterized according to the invention in that the outlet of the nozzle is designed in the direction normal to the slab or pre-strip surface as rectangular or slot-shaped with an arcuate course at least in sections, the width the exit of the nozzle in the conveying direction of the slab or the slab is between 0.2 mm and 1.5 mm and movement means are available with which the distance between the exit of the nozzle and the surface of the slab or the sliver can be adjusted.
  • the nozzle is accommodated in a housing which is pivotable about an axis which is arranged horizontally and transversely to the conveying direction of the slab or the pre-strip.
  • a section or projection can be arranged on the housing which, when the scale washer is used as intended, is arranged closer to the surface of the slab or the pre-strip than the outlet of the nozzle. This enables efficient protection of the nozzle.
  • the outlet of the nozzle can be formed by two adjacently arranged - and preferably linear - nozzle plates. At least one of the nozzle plates can be arranged adjustable in the conveying direction of the slab or the pre-strip and / or in the direction normal to the surface of the slab or the pre-strip and / or transversely to the conveying direction of the slab or the pre-strip.
  • a further embodiment of the invention provides that the outlet of the nozzle is formed by two ruler-shaped nozzle plates arranged adjacent to one another, the two nozzle plates having delimiting edges for the passage of water which, viewed in the direction normal to the surface of the slab or the pre-strip, are at a wedge angle , preferably between 1 ° and 5 °, to the horizontal direction transverse to the conveying direction of the slab or the sliver and wherein the two nozzle plates are designed to be adjustable relative to each other in the horizontal direction transverse to the conveying direction of the slab or the sliver. This allows the size of the nozzle gap to be changed in a simple manner.
  • the edges can also be contoured as desired, in particular with a contour according to an nth order polynomial, so that - similar to CVC technology - there is a parabolic gap change over the width, for example.
  • the outlet of the nozzle is formed by two arbitrarily contoured nozzle plates, the two nozzle plates being able to be adjusted relative to one another in such a way that the gap width changes unevenly across the width of the slab or the pre-strip.
  • the nozzle gap width can also be made adjustable in sections over the width of the slab to be descaled or the pre-strip; accordingly it is provided that the width of the outlet of the nozzle in the conveying direction can be adjusted in sections over the width of the slab or the pre-strip.
  • the scale washer preferably has at least one filter element which has a plurality of bores, meshes or slots, the bore diameter, the mesh size or the slot width being smaller than or equal to the width of the outlet of the nozzle.
  • a filter is therefore preferably arranged in the water supply line, the mesh size of which is smaller than the slot width of the nozzle.
  • the filter element can be arranged in front of the outlet area of the nozzle, the sum of the cross-sectional area of the bores, meshes or slots in the filter element being greater than the cross-section of the outlet of the nozzle.
  • the feed lines to the scale washer and / or the housing of the scale washer and / or all water-carrying components are preferably made of stainless material (preferably steel or copper).
  • a clogging of the narrow rectangular nozzle is prevented by a correspondingly designed filter unit inside the scale washer housing.
  • This is, for example, a cuboid (or with a similar spatial extent) continuous filter unit over the width that is arranged in front of the outlet channel.
  • the filter area can protrude into the distribution channel.
  • the filter unit is provided with small meshes or bores or preferably with narrow slots, the bore, mesh or slot width of which is less than or equal to the width of the outlet of the rectangular nozzle.
  • the sum of the cross-sectional area of the bores, meshes or slots (viewed in the direction of water flow) is larger than the cross-section of the rectangular nozzle in order to keep the flow losses low.
  • outlet of the nozzle is formed by two correspondingly contoured plates which, when shifted relative to one another, change the gap over the width of the slab or the pre-strip.
  • the furnace temperature can be reduced by the temperature difference that arises during descaling due to the lower cooling effect become.
  • the rectangular nozzle unit can be composed of the components water inlet area, possibly a filter plate, a jet straightener, a nozzle compensation section, a jet bundling in front of the nozzle gap and the nozzle gap.
  • the delimiting edges of the two nozzle plates can also be arranged at a different distance from the slab or from the pre-strip or set to such a different distance.
  • the rectangular gap can also be formed in an arc shape.
  • the nozzle gap width can also be adjustable in sections across the width of the nozzle.
  • the nozzle can have a conical outlet gap or a parallel outlet gap in the outflow direction of the water, the length of the outlet gap, measured in the outflow direction of the water, preferably being less than 20 mm and / or longer than three times the width of the outlet of the nozzle.
  • the invention thus proposes a combination of different measures in order to achieve a good descaling result with significantly reduced energy consumption.
  • the distance between the outlet of the rectangular nozzle and the surface of the slab or of the rolling stock is preferably 20 mm, the range between 10 mm and 30 mm also producing very good results. It is particularly advantageous that small distances to the slab or to the pre-strip can be set with a rectangular nozzle without the nozzle overlap over the width being relevant, since it is a rectangular nozzle.
  • the pressure level is preferably kept at 25 bar, values between 10 bar and 40 bar also leading to good results. This results in a significant energy saving.
  • the slot width of the rectangular nozzle is preferably set to 0.5 mm; the preferred range of values for this is between 0.3 and 0.8 mm.
  • the nozzle plates can be designed to be interchangeable. They are preferably made of heat-resistant stainless steel, hardened steel, hard metal or ceramic.
  • the angle of the jet from the nozzle is preferably set so steep that all the water runs against the direction of travel of the belt; an angle between 0 ° and 25 ° is preferred here.
  • the scale washer is preferably arranged in front of the finishing train or behind the slab furnace.
  • the scale washer bar with the rectangular nozzle is preferably mounted in a rocker.
  • a pre-strip or slab head shape detection can be provided in front of the scale washer (optical or mechanical system) and the nozzle position at the head of the slab or strip can be controlled with this.
  • the slot width of the rectangular nozzle can be changed by exchanging the nozzle plates. It is also possible to vary the width of the slot by means of an adjustment mechanism (for example by means of an eccentric or a wedge); for this purpose, a nozzle plate can be displaceably arranged. This makes it possible to compensate for nozzle plate wear. This also makes it possible to open the gap, for example, for a possible nozzle cleaning.
  • the gap of the nozzle is changed only in sections over the width of the rectangular nozzle (transversely to the conveying direction of the slab). In this way, the nozzle gap can be closed in sections, making it possible to adapt the width to different slab widths.
  • the descaling pressure is thus significantly reduced compared to the prior art, with the proposed combination of features nevertheless achieving a largely constant descaling result.
  • the invention accordingly works by lowering the distance and the water pressure while maintaining the same descaling quality.
  • the distance between the nozzle outlet and the slab surface can be adjusted by a corresponding actuator.
  • the use of the rectangular nozzle provided is advantageous here, since a uniform descaling effect or cooling effect is achieved across the width of the slab, regardless of the distance. This also applies to a curved surface of the rolling stock.
  • the amount of water required can be reduced significantly over time. This reduces the cooling effect of the slab or the pre-strip.
  • the lower cooling effect can thus be used to save energy, for example by reducing the oven temperature (heating effect).
  • the invention provides a rectangular nozzle with which a water curtain can be generated and directed onto the slab to be descaled.
  • the proposed configuration is characterized by a cost-effective concept. On the one hand, this applies to the possibility of using low-pressure pumps; In addition, cheaper pipelines and spray bars with thinner walls can be used. The shielding against the high pressure used is also less complex. Furthermore, the wear on the rectangular nozzle is also reduced as a result of the low pressure. This also means that only less maintenance is required.
  • the supply lines to the scale washer and / or the scale washer housing or at least all components in water-bearing areas can be made of rust-free material (e.g. stainless steel, cast iron, copper), since this is not a high-pressure scale washer with the necessary pressure resistance, but only pressure is less than 50 bar. A possible risk of clogging of the narrow slot nozzle can also be countered effectively in this way. Rust then does not occur within the supply lines or the scale washer.
  • rust-free material e.g. stainless steel, cast iron, copper
  • the scale washer also advantageously takes up a smaller installation space, since only one row of nozzles per side has to be provided for the scale washer.
  • the surface of the scale scrubber wetted with water on the upper side can additionally be limited by driving or squeezing rollers in front of and / or behind the scale washer.
  • the squeezing rollers are set to a defined force or to a defined gap.
  • well-proven collecting channels for "skimming off” the water can be arranged.
  • the rectangular nozzle used also results in an optimal overlap of the slab across the width, even if the distance between the nozzle outlet and the slab surface is different.
  • the impact pressure is also kept at least as great as with previously known high-pressure nozzles.
  • the outlet channel of the nozzle can be designed in the form of a pointed slot nozzle in the outlet area.
  • a nozzle with a slightly conical or preferably parallel exit slit with a slit length of less than 20 mm and / or longer than three times the exit slit width of the nozzle can also be used.
  • a scale washer 2 is sketched, with which a slab 1 is descaled on its upper side and on its underside. Accordingly, a nozzle 3 is arranged above and below the slab 1. The slab 1 moves in the conveying direction F past the scale washer 2.
  • each nozzle 3 has an outlet 4, from which water is applied under pressure.
  • the nozzle 3 is one that extends across the width B of the slab 1 (see FIG Figure 5 ) emits a jet 5 in the form of a water curtain, i.e. the nozzle gap at the outlet 4 is a rectangular gap (rectangular nozzle cross-section) which extends over the entire width B of the slab 1 horizontally and transversely to the conveying direction F.
  • the nozzle 3 is arranged in a housing 7.
  • the housing 7 is pivotably mounted on an axis A, which is aligned horizontally and transversely to the conveying direction F.
  • a movement means 6 allows the movement of the housing 7 and thus the up and down movement of the nozzle 3 and thus the nozzle outlet 4.
  • the nozzle outlet 4 can thus be moved in the direction N normally on the slab surface.
  • the distance a between the outlet 4 of the nozzle 3 and the surface of the slab 1 can thus be set.
  • a section or projection 8 is arranged on the housing 7. This section protrudes beyond the nozzle outlet 4 and thus represents a protection for the nozzle 3. Accordingly, there is a distance a 'between the lower edge of the section or of the projection 8 and the surface of the slab 1, which is smaller than the distance a between the outlet 4 of the nozzle 3 and the slab surface.
  • the jet 5, which emerges from the nozzle 3 is oriented against the direction N normal to the slab 1 at an angle ⁇ (see FIG Figure 1 , below). The orientation is opposite to the conveying direction F.
  • the water is fed to the nozzle 3 at a pressure p via a feed line 12. Behind a filter plate 13, the water reaches a jet straightener 14, which consists of grid plates. From here the water reaches a nozzle rectifier section 15.
  • the rectangular nozzle unit is thus composed of the main components water inlet area 12, optionally a filter plate 13, a jet straightener 14, a nozzle compensation section, a beam bundling in front of the nozzle gap and finally the nozzle gap.
  • FIG Fig. 1 A possible embodiment for the filter unit 13 within the scale washer housing 7 or scale washer 2 is shown in FIG Fig. 1 shown.
  • This embodiment is, for example, a cuboid, continuous filter unit 13 which extends across the width and which is constructed in the shape of a bowl and is arranged in front of the rectangular nozzle outlet area 14, 15.
  • the filter protrudes into the distribution channel 21.
  • the filter housing or the filter unit 13 is provided with a large number of narrow slots (in Fig. 1 not visible) whose slot width is less than or equal to the outlet width b of the rectangular nozzle 3.
  • the sum of the cross-sectional area of the bores, meshes or preferably slots is greater than the outlet cross-section 4 of the rectangular nozzle 3.
  • the water therefore flows from the inlet line 12 into a type of distribution channel 21 and further through a large number of slots in the filter unit 13 into the actual nozzle inlet with the jet straightener 14 and the nozzle straightener section 15 and finally to the nozzle outlet 4.
