Definitions
- the invention relates to a system and a method for the aftertreatment of a Metal strip or sheet, in particular made of steel with at least two treatment units.
- This (post) treatment process is usually carried out in several Steps on several system units, the belt after passing through one each unit is rewound and before going through the next one System unit is uncoiled again.
- EP 0 863 222 A1 is known as described that pickling the hot strip and reducing the strip to Finished thickness in a separate or permanently coupled to the pickling device Cold rolling mill can take place. Then the cold rolled Coils are wound into bundles and to a remote galvanizing plant transported to be surface-coated there.
- EP 0 863 222 A1 the cold rolling process with the pickling and Galvanizing process in a complete line in a continuous line to couple.
- the belt treatment plant comprises an inlet part to which a pickling section and a reduction stand for cold rolling as well as directly in line connect a galvanizing part and ends with an outlet part.
- the invention has for its object a system for treating a To provide metal strip and a method that do not have this disadvantage, i.e. offer greater flexibility for the plant operator.
- the individual are according to the system or the system layout Treatment units can be operated independently as well as coupled.
- the Treatment units are flexibly connected to one another via coupling units, with both a belt flow through a separate belt treatment unit as well as a continuous band flow through a selected group of treatment units and thus a predetermined sequence of treatment steps is possible.
- the treatment units are preferably arranged parallel to one another and are such with coupling units, the means for conveying the tape from one Have treatment unit to a parallel adjacent treatment unit, connected that a meandering tape flow occurs within the system.
- meandering means serpentine moving or going through a series of turns that are not necessarily must have the same radius.
- the coupling units allow a flexible band flow, starting from from a first treatment unit to an adjacent treatment unit, the does not necessarily have to be immediately adjacent.
- the respective treatment center In which the beginning of the line is initiated, the system operator determined as required.
- each treatment unit is designed as a completely independent or separate unit, by including an inlet part, a process part and an outlet part.
- the treatment units have a first transition between the Inlet part and the beginning of the process part as well as a second transition between the process part end and the outlet part, the respective coupling units are arranged on at least one of these transitions of each unit.
- the Band that is supposed to go through different treatment processes in succession, is thus meandering from one part of the process to the next.
- each treatment unit depending on the direction from the inlet to the outlet part a basic belt conveying direction.
- the treatment units are so parallel arranged to each other that the basic belt conveying directions are immediately adjacent Treatment units run in opposite directions, with the end of the process division in each case one treatment unit and the beginning of the process part of an adjacent treatment unit are connected via a common coupling device.
- the treatment units are parallel to one another at the same height arranged that the inlet part of a treatment unit the outlet part of a corresponds to each other adjacent treatment unit and where the Belt running direction of the individual treatment units is opposite to each other.
- the units are parallel to each other arranged that the inlet part of one unit the inlet part of another neighboring unit.
- the tape will - if it is a treatment chain subject is promoted by the process part, then in opposite directions Direction back again in order via coupling means at the beginning of the process part to enter the process part of the neighboring unit.
- the tape can, for example, when it is no longer exposed to the process part to be transported along the hall ceiling.
- a meandering band conveyor takes place in both developments, the turns of the first type are approximately the same size, while after the second type of narrow winding within a first process part a large one Turn to a next process part follows and so on.
- the coupling unit can be two immediately adjacent treatment units connect with each other or serves to connect two parallel, but not immediately adjacent, units if, for example, a relative treatment chain to be driven rarely.
- the coupling of two treatment facilities that are further apart will have a corresponding one Belt guide or deflection reached.
- the system according to the invention is preferably a system for Treatment of a metal strip, starting from rolled pre-strip.
- the attachment comprises at least two treatment units, which are one unit to prepare the belt surface and / or a unit for applying a Protective layer on the strip surface and / or a unit for cold rolling.
- the units be parallel are arranged offset to each other. It is recommended that the units comprise at least one inlet part and a process part and so arranged are that the process division end of one unit is roughly the same Height with the beginning of the process part of the neighboring unit is arranged by one to allow meandering transition.
- a specific embodiment offers a particular advantage. It is suggested, that one unit to prepare the surface and a second unit to apply a protective layer combined, both have an inlet part, while the unit for preparing the surface has no outlet part. It can now be rolled separately in the hot rolled are cleaned in the first unit and then surface-coated in the second unit be, the second unit through the separate entrance optionally equipped with cold strip. The result is a system concept with two separate inlet parts.
- the advantage of this layout is that it is scaled Hot strip is introduced into the system completely separately from a cold strip and therefore the scale dust does not affect the treatment of the cold strip.
- the band As a means of conveying the belt within the coupling units for deflection of the tape from one treatment unit to the adjacent treatment unit Combinations of roles come into consideration, the band according to different Redirect techniques.
- the tape After the roll method, the tape is over several rollers arranged one behind the other. She works in a similar way Twist method in which the tape runs through many rolls - in the form of a Loop tower - is redirected. Redirection is also possible with a driven one Roll and twist with a free loop. Preferably point the coupling units on so-called twist rollers.
- Such a twist roll is arranged at an angle of 45 ° to the tape running direction.
- the metal strip is on a helical path around the twist roll guided and deflected by 90 °.
