- the invention relates to a method and a device for pickling and cleaning of rolled steel strip that is looped through several in the treatment line arranged pickling or cleaning container moves through and from the pickling or cleaning medium is applied to at least one hinge side, for which spray or spray units are provided which can be switched on or off and / or are adjustable in their spray width and / or with adjustable spray or spray pressure and / or volume flow and / or changeable temperature.
- This pickling line consists of a tower mounted in a steel frame in which the tape is guided in vertical lines and sprayed with pickling acid, which is used in several floors arranged on both sides of the belt nozzles is directed against the tape, depending on the width of the tape on the have adjustable opening slots for each spray width.
- pickling acid which is used in several floors arranged on both sides of the belt nozzles is directed against the tape, depending on the width of the tape on the have adjustable opening slots for each spray width.
- it is difficult to adapt to other pickling tasks and are also in usually very high towers (e.g. 100 m high) required. Comparable with this Designs and constructions or arrangements are for cleaning systems known.
- the invention has for its object a method and an apparatus to create the type mentioned above, with which the space required for the pickling or Cleaning systems can significantly reduce, and also an exact adjustment to the respective pickling or cleaning task with the aim of a reduced Pickling time or cleaning time and an improved over the range Enable pickling result or cleaning result.
- This object is achieved with a method according to the invention in that the Belt before entering the pickling treatment part or cleaning treatment part from the horizontal belt level to an upright, vertical Belt running level and after running out of the pickling treatment part or Cleaning treatment part redirected to its normal, horizontal belt running level becomes.
- the deflection of the tape into the upright, upright position makes it possible space-saving and space-saving to manage and a variable system structure to achieve, which allows an optimal use of the available space.
- the Container height is determined by the bandwidth, and that in relation to its Width in a standing or vertical manner over in the pickling tank or Guided cleaning rollers with deflection rollers mounted on vertical roller axes
- Belt is preferably from two sides with the pickling medium or Sprayed or sprayed cleaning medium.
- the pickling tanks or cleaning tanks i.e. the containers of the pickling treatment part or cleaning treatment part which in usually has pickling or cleaning and rinsing containers and a dryer, can, depending on the space, cross to the tape running direction or parallel to Belt running direction and thus in series one behind the other or one above the other, i.e. can be built next to each other in the most varied of arrangements.
- the exact pickling line or Set the cleaning distance by more or less spray or spray bars, i.e. Spray units can be switched on or off, whereby only minimal Amounts of acid or cleaning quantities and therefore the smallest storage containers are necessary are.
- spray units can be switched on or off, whereby only minimal Amounts of acid or cleaning quantities and therefore the smallest storage containers are necessary are.
- the applied pickling or cleaning medium is carried along is, so that the pickling or cleaning line inevitable in their setting changed, the medium flows when the belt is guided in an upright position due to gravity largely downwards, with which the setting is maintained.
- a preferred embodiment of the invention provides that the bandwidth differently scaled or contaminated band areas with changed Spray pressure and / or changed acid concentration or cleaning concentration and / or increased volume flow of the pickling medium or cleaning medium be sprayed. This purposefully possible influence on experience has shown stronger scaled or contaminated strip areas, such as in particular at the strip edges, also helps to reduce the pickling time and cleaning time and thus the Pickling tank length or cleaning tank length at.
- the turning rollers have vertical axes associated tensioned roller sets that hold the belt in the middle of the system, whereby the required belt tension over the vertically acting frictional forces between the Rolls and the tape is generated.
- At least one of the pickling tanks or Cleaning container arranged belt deflection rollers is designed as a control roller and / or the belt deflection rollers are preferably also assigned pressure rollers.
- the control roller or rollers of which depending on the pickling tank length or Cleaning container length one or more are designed to serve one possible correction of the tape run. Which especially with thicker strip thicknesses and long pickling tanks or cleaning tanks with an additional drive provided pulleys are the same as belt tension losses caused by bending again and thus support the maintenance of the required Strip tension.
- the ultrasonic actuators be in one of outlet-side sealing rollers limited, narrow separate chamber are arranged, and there advantageously distributed over the range behind acid-resistant or alkali-resistant partition walls in each case on the front side of the chamber.
- the separate chamber is formed by means of the sealing rolls on the conveyor belt, i.e. in the respective Pickling tank or cleaning tank divided. This offers the opportunity to Coupling the sound energy to the chamber constantly with acid or cleaning solution to flood and thus the transmission of sound energy to the belt surface favor.
- the Pickling part or cleaning part 2 comprises three pickling containers or Cleaning containers I, II and III, which are a container IV for rinsing and drying of the metallic strip 5 that is to be passed through, to be pickled or cleaned followed.
- the individual containers I to IV are on via supply and return lines 6 that store a necessary amount of acid or cleaning solution Storage container 7 connected to which to promote the acid or Cleaning solution for application to the belt surface assigned to pumps 8 are.
- These supply to both in the pickling tanks and cleaning tanks Sides arranged transversely to the belt run spray or spray bar 9, which in Embodiment (see FIGS. 7 and 8) as tubes with arranged therein Spray nozzles 18 are formed which are directed towards the belt surface and a Generate the desired spray pattern 19.
- the spray or spray bar 9 and its nozzles 18 can also be switched on or off, depending on the bandwidth Adjust 20 and run so that targeted areas of the metallic tape, the are particularly heavily scaled or contaminated, with either higher spray pressure and / or changed acid volume or cleaning solution volume, changed Acid temperature or cleaning solution temperature and / or with acids or Cleaning solutions of other acid concentrations or cleaning solution concentrations be sprayed or sprayed.
- the spray or spray bar 9 can also operate discontinuously in the system be completely switched off.
- the width of the metallic band 5 is in a standing or upright way over in the pickling chambers or cleaning chambers I to IV with vertical axes 21, i.e. Deflection rollers arranged upright in roller bearings 10 meandering out (see. Fig. 2).
- a horizontal Deflection roller 12 To set up the metallic band 5 in its upright position is the pickling or cleaning part 2 a horizontal Deflection roller 12 and a 45 ° raised or 45 ° above the horizontal inclined inlet turning roller 11 upstream.
- the band 5 is perpendicular upwards or downwards to the turning roller and from there guided into a tensioning roller set 13, the tensioning rollers 13a, 13b of which are upright, i.e. are stored with vertical axes over which the band 5 then through the individual container I to IV of the pickling part or cleaning part 2 is moved through.
- Outlet turning roller 14 inclined or raised at 45 ° to the horizontal arranged on which the pickled or cleaned belt 5 with a two Tensioner rollers 15a, 15b having tensioner roller set mounted on vertical axes 15 coming down or up and the tape 5 runs into the horizontal tape running level so that the treated tape subsequently can be reeled up or immediately run into a downstream rolling mill.
- pickling or cleaning containers I to IV passes through the belt 5 the lid 16 of the first container I and leaves one area for rinsing and for drying, the last container IV also through the lid 16; the individual containers I to IV are here in parallel one behind the other.
- the containers I to IV are parallel to The belt running direction 1 is arranged, the belt 5 passing through both on the inlet and outlet side the respective container side wall 17 enters or exits the treatment part.
- Cleaning treatment parts 102 and 202 in a row in a row, the 4 shows a zigzag arrangement of the container.
- the modifications of the pickling and cleaning treatment parts 302 and 402 5 to 6 are the containers I and II in a compact arrangement one behind the other and the containers III and IV are - seen in the plane of the drawing - arranged above, the band 5 in each case the last container IV from the trained dry area IVa leaves, which is equally for the Arrangements according to FIGS. 1, 2 and 3 applies. Due to the container arrangement Fig. 6 runs - unlike all other versions - the band 5 on the same Page in the pickling or cleaning treatment part 402 and out there. Apart from the different arrangement and location of the containers I to IV or IVa the other components do not differ from those of FIGS. 1 and 2, so that these matching components in all versions with the same Reference numbers are provided.
- FIG. 7 and 8 show details of constructive, advantageous configurations the pickling tank I to IV is shown, namely that according to FIG. 7, in this case with a drive 22 connected via a clutch 23 and a gear 24 Deflection roller 10 assigned a pressure roller 25, the swivel lever 26 in one Frame 27 is mounted. 8 is a deflection roller as Control roller 100 formed and for this purpose in a swivel frame 28th arranged or stored, which in turn by one on the steel structure attached base frame 29 is added, the guides 30 for the Has pivot frame 28.
- the band 5 here has a compared to FIG. 7 smaller bandwidth 20, and there are accordingly fewer spray nozzles 18 switched on.
- First container I provided several ultrasonic actuators 31. These are in one of inlet and outlet-side sealing rollers 32 limited, narrow separate chamber 33 each arranged behind acid-resistant or alkali-resistant partition walls 34.
