1. F:ield of the Invention The present invention relates to a method and a plant for manufacturing a cold-rolled, galvanized and pickled metal strip.
The method starts from a hot-rolled initial strip which is first pickled, then cold rolled and subsecIuently galvanized. The plant includes a cold-rolling mill which is either separate and coupled to a pickling unit and a hot galvanizing unit for annealing and for coating the cold-rolled strip.
2. De~-~cri~tion of the Related Art In orcler to manufacture cold-rolled, galvanized strip, it is known in the art to pickle a hot-rolled initial strip in a pickling line. Pickling has the purpose of eliminating the scale layer produced during hot rolling, on the one hand, and of removing an oxide layer formed on the strip, on the other hand.
Subsequent].y, the pickled hot strip is deformed with respect to thickness i.n a cold rolling mill in order to achieve the desired finished thickness which usually is less than lmm. After the cold-rolling process, the strips coiled into coils are annealed and coated, for example, in a hot galvanizing plant.
CA 02228772 1998-02-0~
In conventional methods, this strip treatment process takes places in several steps. This means that pickling of the hot strip and reducing the strip to finished thickness takes places in a separate cold-rolling mill or a cold-rolling mill coupled to the pickling unit. As described above, the cold-rolled strips are wound into coils and are conveyed, for example, by means of a crane, a ground level transportation vehicle or an air cushion transport system to a remotely located hot galvanizing plant where the strips are annealed and coated.
These method steps have a very disadvantageous effect on the production capacity of cold-rolled, galvanized strip, particularly due to the time-consuming coil handling step between cold-rolling mill and galvanizing plant. Moreover, the coil handling procedure requires additional personnel, so that the total manufacturing costs of the cold-rolled and refined strip are significantly increased. As a result, the possibilities of selling the product on the very competitive steel market are substantially limited.
CA 02228772 1998-02-0~
SW ~ARY OF T~E lNVh~ llON
Therefore, it is the primary object of the present invention to further develop a method and a plant of the above-described type in suc:h a way that a faster and less expensive manufacture of the refined strip becomes possible.
In acc:ordance with the present invention, the strip is cold-rolled and galvanized continuously and successively in a continuous treatment line.
The aclvantageous feature of coupling the cold-rolling process to the pickling and galvanizing process in a continuous line means that the previously necessary, time-consuming and expensive coil handling step between the cold-rolling mill and the galvani.zing plant is omitted. This means that the production capacity of the entire treatment plant is increased, while the recIuirement: of personnel is reduced. In addition, since coil handling is no longer necessary, the investment costs for the treatment line according to the present invention are substantially lower.
CA 02228772 1998-02-0~
In summary, the advantages described above mean that the production costs per ton of refined, cold-rolled strip are substantia:Lly reduced.
In the plant according to the present invention for carrying out the melhod of the invention, at least one reducing stand is arranged between the pickling unit and the galvanizing unit of a treatment plant.
In this reducing stand, the strip arriving from the pickling unit is di~ectly and continuously cold-rolled with one reducing pass to finished thickness. However, it is also conceivable to use severa:L subsequently arranged cold rolling stands for achieving greater decreases of the strip thickness.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of the disclosure. For a better underst~n~'ng of the invention, its operating advantages, specific objects attained by its use, reference should be had to the drawing and descriptive matter in which there are illustrated and described preferred embodiments of the invention.
BRIEF DESCRIPTION OF THE DRAWING

The si.ngle figure of the drawing is a schematic illustration of a strip treatment line according to the present invention.
CA 02228772 1998-02-0~
DESCRIPTION OF THE PREFERRED EMBODIMENTS
As illustrated in the drawing, the plant according to the present invention is a continuously operating strip treatment line 1 for pickling, cold rolling and galvanizing a strip 2.
The slrip treatment line 1 includes an entry unit 3 in which the strip 2 previously hot-rolled and coiled into a coil is uncoiled by a reeling device 4. In addition, the inlet unit 3 is equipped with a strip welding machine, not shown in the drawing.
By welding individual coils together to form an endless strip, the strip welding machine produces the advantageous effect of a continuous strip travel.
The entry unit 3 is followed by a pickling unit 5 in which the strip 2 is pickled, for example, electrolytically or by an acid flow medium, in order to remove scale layers produced during hot rolling. Subsequently, the pickled strip 2 is directly introduced into a reducing stand 6 and is deformed with respect to thickness in order to achieve the desired finished thickness.
After the cold rolling process, the strip 2 travels through a cleaning unit 7 in which, for example, rolling oil or rolling emulsions and thin oxide films caused by pickling are removed.
CA 02228772 1998-02-0~
This makes possible a good adherence of a zinc layer which is applied to the strip in the subseq[uently arranged galvanizing unit 8 whic:h operates, for example, by hot dip galvanizing or electrolyti.cally.
Subsecluently, the galvanized and, thus, corrosion-protected strip 2 travels through a skin pass stand 9 in which it is smoothened. A stretching and leveling unit 10 following the skin pass stand 9 eliminates by cooperating with the skin pass stand 9 any planarity deviations caused by rolling and annealing, such as, edge undulations or full centers of the strip.
Subseq[uently, the refined and rolled strip 2 is coiled into a coil in a reeling device 12 arranged in the entry unit 11 of the treatment line 1.
While specific embodiments of the invention have been shown ,and described in detail to illustrate the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
Subsequent].y, the pickled hot strip is deformed with respect to thickness i.n a cold rolling mill in order to achieve the desired finished thickness which usually is less than lmm. After the cold-rolling process, the strips coiled into coils are annealed and coated, for example, in a hot galvanizing plant.
