Definitions

  • the invention relates to a method and a device for guiding a steel strip during its passage through a continuous strip treatment system equipped with a series of treatment stations, the direction and / or track of the strip being set as desired and / or the strip being removed from the strip for control purposes by visual inspection Bottom to top - or vice versa - is turned.
  • a known treatment plant for steel strip comprises, for example, stations for a continuous sequence of treatment steps such as degreasing, annealing, galvanizing, skin-dressing, painting, checking, winding, etc.
  • a hot-dip galvanizing and painting plant as is shown by way of example in FIG the so-called "good side" of the strip is turned from the underside to the top in order to make it accessible for inspection by visual inspection, the underside of the strip emerging from the galvanizing bath initially continuing in the continuous strip running direction The underside of the band remains.
  • dressing for example by roughening the surface of the belt and then winding it up, the underside of the belt must then be turned towards the top of the belt for continuous visual inspection.
  • the strip is fed vertically upwards into a steel structure below the high hall roof in the longitudinal direction over the system parts, at the end of the hall vertically downwards and then horizontally against the belt running direction of the inlet part of the system for further treatment and winding.
  • the belt is transported just below the roof of the approx. 40 m high hall via the outlet group with outlet loop tower and further via the coating device.
  • This requires a long, stable and high steel construction with idlers for guiding the belt as well as a built-in crane for handling the plant components underneath.
  • the required high hall is correspondingly long, for example 150 m. This results in a further disadvantage because the long horizontal distance of the high-lying belt guide can lead to belt running problems and belt damage on the idlers.
  • the invention has for its object to provide a method and an apparatus for guiding a steel strip during its passage through a continuous strip treatment system, which avoids the aforementioned difficulties, in particular when transferring the strip in the area of the roof structure of the hall, and consequently a substantial reduction in the high Hall construction and at the same time improved belt guidance, preferably while maintaining the tape running direction through the system.
  • the object is achieved with the invention by a method according to the features of claim 1.
  • One embodiment provides that the band is twisted by an angular amount (Phi) of 180 o in total, such that at the end of the deflections by 180 o the underside of the belt is turned when entering the first roll of the belt turning tower to the top of the belt when it is discharged from the last roll, and vice versa.
  • the belt is guided in the belt turning tower within a comparatively short horizontal distance, respectively via deflection rollers arranged below and above, and twisted from roll to roll by an angle (Phi), so that in the event of a deflection around the last lower roll with a total of 180 o the underside of the belt at the inlet is turned towards the top of the belt at the outlet.
  • This also results in a shorter and lower hall construction and a more controllable belt guide.
  • the belt running direction can be maintained unchanged through the entire system if necessary, which provides a better overview and control over the individual stations of the continuous belt processing system.
  • the belt can also be adjusted in its running direction or be guided through parts of the system with its tracks running parallel to one another.
  • an embodiment provides that the permissible twist angle (Phi) of the band between an upper and a lower roll depends on the ratio of the free length (L) of the band between the two rolls to the band width (B) and the resulting permissible edge tension (Sigma) of the tape is determined.
  • crowned rollers are used in the belt turning tower.
  • an embodiment provides that the crowning-determining diameter difference (D - D ') of a roll is approximately the amount that arises between a pair of rolls and one due to the band being twisted by an angle (Phi) for a given free band length (L) of the band Elongation of the band edge areas causing the edge extension (Delta L) corresponds.
  • one embodiment of the invention provides that the belt in the deflecting tower is pivoted in the passage through a first group of rollers to an angle which deviates from the direction of its entry track and after passing through a straight intermediate section corresponding to the amount of the lateral displacement in a second group of deflection rollers is swiveled back into the original direction of its entry track.
  • the tape for compensating for a lateral displacement caused by the diverting pulleys in the belt contact (S), the tape o twisted more than 180 in a first group of deflection rollers at least an angular amount, the angle (beta) to the belt inlet axis (xx) out of the last, lower roller in a piece of straight longitudinal guide in the direction against the tape outlet axis (yy), by the amount (S) of the lateral offset into a second group of deflection rollers and an angular amount in the direction of the Belt inlet axis (xx) coaxial belt outlet axis (yy) is pivoted.
  • the strip is returned within the tower while maintaining the strip running track through the center of the system from start to finish.
  • means for controlling the center of the strip are provided in front of and behind the belt turning tower.
  • a device for guiding a steel strip in a treatment plant for steel strip having stations for continuous sequences of treatment steps such as degreasing, annealing, galvanizing, skin-dressing, painting, checking, winding, etc., for carrying out the method according to the invention, is characterized by a Kind of a vertical loop storage trained belt turning tower with a number of vertically spaced upper and lower belt deflection rollers, these in the direction of the belt from roll to roll in the same direction, occasionally to 180 o cumulative angular amounts (Phi1 to Phi n ) relative to the tape inlet axis (xx) are arranged twisted, such that the belt twisted by wrapping a pair of rollers formed by a lower and an upper roller by an angular partial amount (Phi) and occasionally with a sum of all twist angle amounts (Phi1 to Phi n ) of 180 o from the U underside to the top - and vice versa.
  • An additional embodiment can be provided, according to which the upper deflection rollers have means for adjusting the vertical distance from the lower rollers. In this way, differences in length of the strip within the strip turning tower can be compensated for in a simple manner without additional provision of a loop storage device.
  • a further embodiment can provide that the upper rollers of the turning device have means for setting and preferably keeping the tension state constant in the continuous belt.
  • Such Means can be, for example, hydraulic piston / cylinder units which hold the upper rollers in a predetermined tension state of the rotating belt.
  • the means for length and voltage compensation can form a unit.
  • the difference in diameter between the center and end face of a spherical roller corresponds approximately to the amount of the edge elongation of the ribbon caused by twisting the ribbon by an angular amount (Phi) for a given bandwidth and center distance of the rollers, the ribbon becomes effective from increased edge tensions relieved, while the tape guide properties of the rollers are also improved. It is also an uncomplicated measure.
  • a special embodiment provides that the belt turning tower has two separate groups of roller pairs which are connected to one another by a straight running path of the belt in the direction of a belt outlet axis (yy) coaxial to the belt inlet axis (xx), the sum of the angular amounts of both groups preferably accumulates to 180 o .
  • This configuration ensures that the belt run is maintained in a line through the center of the system from the inlet to the outlet of the belt.
  • any parallel offset during the tape transport can be set with this device. Even with one appropriate combination of twist angles any setting of the tape running direction can be achieved.
  • Another essential embodiment provides that the upper and lower rollers, as seen in the vertical projection, are assigned to one another in such a way that the side lines of two rollers leading a common belt section and rotated relative to one another by an angular amount (Phi) each intersect in half their length .
  • This measure ensures in a simple manner that the belt maintains a secure center guidance on each roll when running through the successive pairs of rolls.
  • Fig. 1 shows a combined hot-dip galvanizing and painting system in a conventional design with a first low hall part (40) and a subsequent approximately 40 m high and 150 m long hall component (41).
  • the inlet group (1) in which tapes (30a, 30b) that can be unwound from two coils are combined to form an endless belt (30), which is then passed through a degreasing station (2) followed by a horizontal one Loop storage (3) is inserted into the high hall part (41).
  • the strip (30) is first passed through a glow station (4) annealed without tension, and after passing through a downstream cooling device (5) in the galvanizing station (6) galvanized.
  • the belt After passing through another cooling section (7), the belt is vertically upwards into a steel structure (8) and horizontally below the roof of the high hall (41) at a height of approx. 40 m above the system parts (9 - 12) at the end of the hall vertically downwards and then again horizontally in the opposite direction of the belt run to the inlet part (1) for further treatment, first through skin pass stands (9), then through a straightening / straightening device (10) and out of this through the fully automatic painting device (11). From this the galvanized and coated strip passes through a vertical discharge loop tower attached to the coating device into the discharge group (12) and is wound there on coils. At the locations marked with "X", e.g. B.
  • the strip (30) is subjected to a check by visual inspection (X).
  • X visual inspection
  • the original underside (33) of the band (30) is turned over to the band top (34).
  • This is done in the conventional design of the system by turning 2 x 90 o in the vertical section (35) between the steel structure (8) and the inlet into the skin pass mill (9). It can be seen that for the height of the hall (41), its length and the required high and long steel structure (8) this requires a comparatively extremely high effort to turn the belt (30).
  • Another disadvantage is that the tape runs in opposite directions. There is also a risk that the tape in the high Steel structure (8) is damaged by imprecise and difficult to monitor barrel.
  • FIG. 2 A system according to the present invention with a belt turning tower (20) is shown in FIG. 2.
  • the belt turning tower (20) is arranged between the galvanizing station (6) and its downstream cooling section (7) and the skin pass mill (9) approximately in the first third of the high hall (41).
  • the belt turning tower (20) it is achieved that the high and expensive hall construction is shortened by approx. 40 m and the shortened part is replaced by a lower hall (42) accommodating the outlet group (12).
  • Their height is approx. 15 m compared to approx. 35 m of the high hall.
  • the incoming with the underside of the belt (33) belt (30) o turned 180 in the strip turning tower (20) and interacts with the "good side” as the tape top side (34) of the belt turning tower (20).
  • FIGS. 3a to 3c Different possibilities for turning the tape by 180 o are shown in FIGS. 3a to 3c using three examples.
  • the band (30) is twisted about 2 x 90 o, wherein very high edge stresses occur. These could only be compensated for within tolerable limits by a very large free tape length (L), which would, however, require an uneconomically high outlay.
  • L free tape length
  • there are four twists with an angle of 45 o to a total of 180 o Even more favorable conditions are obtained as shown in Fig. 3c by six twists to each 30 o with 7 rollers (21, 22) with a substantially reduced length (L).
  • the same "good sides" of the belt (30) are at the inlet as the underside (33) and at Spout designated as top (34) with the inspection side (X).
  • the belt turning tower (20) is designed with a number of upper (21) lower (22) belt deflection rollers arranged at a vertical distance, similar to a vertical loop storage device.
  • the upper belt deflection rollers (21) and the lower rollers (22) arranged between the first and last lower rollers (22c, 22d) are in the direction of travel of the belt (30) from roller (21) to roller (22) and vice versa in the same direction, to 180 o cumulative angular amounts (Phi1 to Phi n ) rotated relative to the tape inlet axis (xx).
  • This arrangement can be seen particularly well from FIG. 5.
  • the guy length is marked with (L), the tape entry axis with (xx) and the coaxial tape exit axis with (yy).
  • the upper deflection rollers (21) of the turning device (20) can have means (25) for adjusting the vertical distance (L) to the lower rollers (22, 22c, 22d). Such a possible change in distance is designated in FIG. 4 by "D".
  • the means for adjusting the distance are indicated purely schematically with arrows (25).
  • Such means (25) can be identical to one another and can consist, for example, of piston / cylinder units.
  • a return of the belt (30) within the turning tower (20) ensures, if necessary, the retention of the belt run in a line from the beginning to the end of the system and thus the coaxiality between the belt inlet axis (xx) and the belt outlet axis (yy).
  • the belt turning device of the belt turning tower (20) has two groups (20A) or (20B) of roller pairs (21a; 22a) or (21b; 22b); which are connected to one another by a straight belt running path (31) of the belt (30) which runs at an angle (Beta) to the axis (xx).
  • the angular amounts (Phi1 to Phi n ) of the two groups (20A) and (20B) add up to 180 o .
  • FIG. 6a shows the twisting of a band section (32) at a center distance (L) between an upper roller (21) and a lower roller (22) in a purely schematic manner.
  • a central rolling process and exact running of the belt section (32) is ensured in that the upper and lower rollers (21, 22), as seen in the vertical projection in FIG. 6b, are assigned to one another in such a way that the side lines (28 and 29 ) two rollers (21 or 22) intersect in the area of the belt centers (xx) or (yy) of half the belt widths (B / 2).
  • the band section (32) is reliably guided with its band center lines (xx) or (yy) over the center of each crowned roll (21 or 22).
  • the deflection rollers (21 or 22) are spherical.
  • the difference in diameter (delta D) between the center (D) and the end face (D ') of a spherical roller (21, 22) corresponds approximately to the amount of the edge extension (delta) caused by the twisting of the band (30) by an angular amount (Phi) L) with constant center distance (L) of the rollers (21 or 22).
  • An exemplary embodiment shows the conditions for a practical embodiment as follows: - strip thickness: 0.2-0.8mm - bandwidth: 750 - 1500 mm - free guy length: approx. 30 m - roll diameter: approx. 800 mm - deflection angle per pair of rollers: 30 o
  • the roll bales e.g. 3 - 4 mm in diameter with a roll diameter of 800 mm and a bale length of 1800 mm, also ensure a self-centering effect and thus exact tape running.
  • Belt center control units are preferably provided in front of and behind the belt turning tower.
  • the belt turning tower (20) By using a belt turning tower (20) for guiding or turning the belt (30), a clear and uncomplicated device is created which can be used at any point in the system. At the same time, the height and length of the large hall (41) is reduced with considerable cost savings and the belt (30) runs in the same direction from the infeed station (1) to the outfeed station (12) of the system. Further cost savings and technical advantages result from the fact that the belt turning tower (20), in the manner of a vertical loop storage device, can have means (25) for belt length compensation and / or for maintaining a constant tension state of the belt (30).
  • the invention also opens up the possibility of arbitrarily setting the tape running direction or of deflecting the tape with a parallel offset from a first track into a second track running at a distance from it. This opens up uncomplicated possibilities of tape guidance through different Plant parts of a multi-part plant complex.

  • the strip (30f) runs into the tower (20) is therein pivoted in its running direction by 90 ° and, without being turned over, continued from the tower (20) in the part of the system II.
  • FIG. 8 can be carried out individually or in groups at the same time in a correspondingly designed belt turning tower (20). They only serve to show the different possibilities of the tape guide in the tower (20), depending on its design with one or more groups of vertically spaced deflection rollers.
