Abstract

PURPOSE:To permit easy traveling of a steel strip in the succeeding stage by providing a leveler on the inlet side of an outlet-side tension reel and correcting the shape in the rear end part of the strip by means of the lever. CONSTITUTION:A deflector roll 3 which deflects a steel strip 4 and an outlet- side tension reel 2 which takes up the strip to form a coil 5 are installed on the outlet side of a final stand 1 of a cold rolling mill. A leveler 7 driven by a screw-down device 6 is installed between the roll 3 and the reel 2. The leveler 7 is constituted of straightening rolls disposed respectively by plural pieces each above and below the strip 4. When the rear end part of the strip 4 is going to be passed therethrough, the leveler 7 is closed by the device 6 to bring the straightening rolls into press contact with the front and rear of the strip 4. A distortion such as an upward camber at the rear end of the coil 5 is thus decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of an outlet device of a copper strip processing line.
%K, by arranging a leveler to correct the shape of the rear end of the copper strip on the input side of the exit tension reel, distortion such as warping of the rear end of the coil can be reduced. Regarding structure.

Output of copper strip processing lines such as cold rolling equipment and pickling equipment
A tension reel is installed on the exit side of K, and the copper strip after passing through the line is rolled up by this reel to form a coil, and then transported to the next goni.

FIG. 1 is a diagram illustrating an example of the structure of a conventional exit device of a copper strip processing line, with cold rolling equipment in a row.

In FIG. 1, a deflector roll 3 is provided between the final stand J and the exit tension reel 2 of the cold rolling mill, and the steel strip 4 coming out of the final stand 1 is deflected by the deflector roll 3. It is wound up on the tension reel 2, and a wound coil 5 is formed.

When rolling is completed in such a conventional winding state, there is a problem in that the rear end of the winding coil 5 is warped upward due to the deflection position relationship between the pass line of the final stand 1 and the deflector roll 3. be. In the next process of manufacturing cold rolled steel sheets, the rear end of the winding coil 5 becomes the tip when unwinding, so if this part is warped in one direction, it will be difficult to thread the tip. becomes difficult.

In addition, in order to correct the warpage of the tip of the copper band, the tip Jl of the next process is
Although it has been implemented to provide a feed leveler etc. on the board part, it is difficult to thread the board through the feed leveler if the tip is warped in the direction as described above. The issue had not been resolved.

The purpose of non-invention is to solve such problems in the prior art.
It is an object of the present invention to provide an apparatus for a copper strip processing line that can easily pass through the next process by correcting the shape of the rear end of the coil wound by the exit tension reel.

A feature of the present invention is that a leveler is provided on the input side of the output tension reel, and the leveler corrects the shape of the rear end of the copper strip, thereby achieving the above object.

That is, according to the invention, f
r Roll the steel strip onto the exit tension reel Kmffte coil ['
In the output side device of the T-filter steel strip ripening egg line, the output side ten/
A leveler is placed on the input side of the gin reel, and is in an open/closed state through which at least the rear end of the copper strip passes through. Provided is an outlet device for a steel slip treatment line, which is characterized by reducing strain on the steel plate.

An embodiment of the present invention will be described below with reference to FIG.

FIG. 2 is a diagram showing the case where the present invention is applied to cold rolling equipment. On the exit side of the final stand 1 of the cold rolling mill, there are a deflector roll 3 for deflecting the steel strip 4 and a deflector roll 3 for deflecting the steel strip 4. An outlet tension reel 2 is installed that winds up the steel strip that has passed through the deflector roll to form a coil 5. Further, on the input side of the tapping tension reel 2, that is, in the row shown, a deflector roll 3 and an output tension reel are installed. A leveler 7 driven by a rolling down device 6 is arranged between the side tension reel 2 and the side tension reel 2 .

Is this leveler 7 placed above and below the steel strip 4? 1. Consisting of straightening rolls with several bubbles each, pressure 1 - device 6
By pressing these straightening holes against the front and back sides of the copper strip, strain is removed and the shape of the core steel is corrected.

When using it, during normal continuous rolling, it is necessary to roll it down (?'?
6, the leveler 7 is kept open and not in contact with the steel strip 4. When the steel strip 4 has finished being pulled out of the unloading device of the cold L rolling mill and the rolling mill has slowed down, that is, when the rear end of the steel strip 4 is ready to be passed, the rolling #6 Close the leveler 7 and bring the straightening roll into pressure contact with the front and back sides of the copper strip.

In this way, the rear end of the steel strip 4 is straightened immediately before the exit tension reel 2 and then rolled up, so that distortions (-I; warping, etc.) that conventionally occur due to the positional relationship with the deflector roll 3 are eliminated. Removed and rolled up: "Distortion such as warping in the F direction at the rear end of the film 5, which will be the tip threading part in the next process, can be removed, making threading easier at the 19th workshop. Be able to do that.

Note that the tension of the steel strip 4 when the leveler 7 performs the above-mentioned straightening can be maintained by the output tension reel 2.

1. When using cold rolling equipment KM according to the present invention
The present invention can be similarly applied to any type of equipment as long as it is a steel strip ripened egg line equipped with an outlet tension IJ.

As is clear from the above description, according to the present invention, a copper strip processing line can correct distortions such as upward warping of the rear end of a wound coil, and facilitate threading in the next process. An outlet device of 1 is obtained.
