圧延して製品とする。2. Description of the Related Art In the rolling of rolled steel, slit rolling for rolling a rolled steel such as a rod or a wire rod is a rolling method for dividing a rolled material into a plurality of pieces along the longitudinal direction at a position close to rolling of a final product. In this slit rolling method, the material to be rolled 1 is rolled and divided through the steps shown in the rolling sample of FIG. 4, and then rolled again to produce a product having a predetermined cross-sectional shape. That is, first, as shown in FIG. 4a, the material 1 to be rolled is rolled into a concave shape by a rolling roll, and then rolled as shown in b and c. Immediately after rolling as shown in FIG. 4c, the material 1 to be rolled is equally divided in the longitudinal direction by a slitter 4 consisting of a pair of knives 2 shown in FIG. 5, and two strips are provided as shown in d of FIG. Divide into pieces 5 and 6. Then, the strips 5 and 6 are sequentially passed through the rolling stands through the pair of split rollers 7 and 8 and the pinch rollers 9 and 10 shown in FIG. Roll as above to obtain a product.

タリングされる。The material 1 to be rolled is b and c from the shape of a in FIG.
After passing through the shape of, the slitter 4 is used to set the two left and right strips 5,6
However, the reason why the cross-section is formed in a concave shape in the state of a is to facilitate the guide so as to distribute the cross-section to the left and right when rolling into the shape of b.
When the material 1 to be rolled is rolled into the shape shown in FIG.
As shown in Fig. 1, roll the rolled material 1 around the axis from a to a '.
Rotate 45 degrees. Then, the depression of a ′ of the material to be rolled 1 and the depression of the central portion of b ′ are matched, and a ′ and b ′ are substantially centered.

Divide and divide into a standard length with the standard shear 17. At this time,
A sample is taken out by the sample collecting device 18 and the cross-sectional areas of the left and right products are checked.

圧延材1 をスリッタ4 により左右２本の条材5,6に分割
するが、現実的には左右の製品の断面積に差が出る。When performing slit rolling, as described above, after rolling so that the centers of the depressions match in the sectional shapes shown in a'and b of FIG. 6, the material 1 to be rolled is rolled. The slitter 4 divides it into two strips 5 and 6 on the left and right, but in reality there is a difference in the cross-sectional area of the left and right products.

レット単位で云うと５〜30本程度に相当する。How to reduce this difference is necessary for left and right products to be the same. Practically, the smaller the cross-sectional area of the left and right products becomes the standard of rolling, the thicker one of them becomes an unnecessarily thick product, resulting in poor yield and high rolling cost. Further, this difference becomes clear when the sample is collected by the sample collecting device 18 and the cross-sectional areas of the left and right samples are checked. But after rolling
The product flows to this place after 5 to 15 minutes, which corresponds to about 5 to 30 rolled billets.

Even if it can be used as a product, the left-right variation causes a reduction in yield and loses cost competitiveness. In view of such conventional problems, the present invention makes it possible to detect unevenness in the cross-sectional area of each strip when the strip is divided into a plurality of strips by a slitter.

る。FIG. 2A shows a plan view of the rolled material 24 and the like during slit rolling, and FIG. 2B shows cross-sectional shapes a to f at the portions a to f on the rolled material 24 side. As shown in FIGS. 2A and 2B, when one rolled material 24 is divided into two along the longitudinal direction, a difference in cross-sectional area may occur between the left and right strips 27, 28. In this case, the loop amounts of the left and right strips 27, 28 are different, and at the same time, the relative difference X is generated between the tip positions of the left and right strips 27, 28. That is, the rolled material 24 of a is replaced by b
When the material to be rolled 24 is displaced to the right as shown in FIG. 2B when being guided to, the difference between the cross-sectional areas of the left and right strips 27 and 28 that divide the material to be rolled 24 into two, and Since the cross-sectional area of the strip 28 becomes large, when the strips 27 and 28 are rolled by the rolling rollers having the same carribean groove, the reduction rate of the strip 28 on the right side becomes large. For this reason, compared to the strip 27 on the left side, the strip 28 on the right side
The leading edge position of the strip 28 on the right side advances, so that a relative difference X occurs between the tip positions of the strips 27 and 28.

に調整する。Therefore, by measuring the relative difference X between the strips 27 and 28, the degree of unevenness of the cross-sectional areas of the strips 27 and 28 can be known. That is, when the tip positions of the strips 27 and 28 pass through the fourth rolling stand 23, immediately after that, the image sensor of the tip position detector 29 images the tip portions of the strips 27 and 28, and the relative difference between the two. Find X. As a result, it is possible to know in real time that the cross-sectional areas of the strips 27, 28 are not uniform, and it is possible to quantitatively know the extent of the unevenness. Therefore, based on the degree of the unevenness, the guide device 25 is moved to the left side, and the material to be rolled 24 is moved to the left side so that the left and right cross-sectional areas are equalized.

FIG. 3 shows a second embodiment of the present invention, in which the tip position detector 29 and the guide device 25 are connected so that the guide device 25 is automatically controlled. The guide device 25 is movable left and right by a screw type moving device 31, and the moving device 31 is provided with a drive source 32 such as a forward and reverse rotation type motor. The drive source 32 is controlled by the output of the tip position detector 29 via the converter 33. 34 is a rolling stand group.

Control the source 32. Then, the guide device 25 is moved in the left-right direction via the moving device 31 to adjust the unevenness and to divide the device into equal parts. If the relative difference X is within a certain limit (permissible yield value), it is set as a dead zone, and the guide adjustment signal is output only when the relative difference X is larger than that.
