れる。(Prior art) In hot rolling of H-section steel, the material to be subjected to the process is a plastically deformed body, so when a rolling force is applied, metal flow occurs in its cross section and in the longitudinal direction, allowing it to deform freely. However, in terms of product quality, H-beam steel must have the center of the web aligned with the center of the flange width, that is, the length (leg length) from the web surface to the flange width end surface must be the same. (see Figure 6) is extremely important, and references related to this include, for example, Japanese Patent Publication No. 53-34587 and Japanese Patent Application No. 1-29995.

の余地が残されていた。(Problem to be Solved by the Invention) The equipment used when rolling H-section steel usually includes a heating furnace, a breakdown end, a transfer, a rough universal mill, and a finishing universal mill. The rolled material (see Fig. 7) and rolled into a rough shape steel piece by groove rolling with a breakdown mill is a rough uniform steel group, and the flange part has an angle, but the flange thickness, flange width, Each cross-sectional dimension such as the web height was rolled until it reached the product dimension, and then the flanges were raised using a finishing universal roller and the web and flanges were lightly rolled down to produce the final product. By the way, in the conventional rolling method, it is difficult to roll each cross section to a predetermined size in the rough universal rolling stage, and it is necessary to correct and straighten the dimensions of the material in the finish rolling stage. As a technique for dealing with this, the technique disclosed in the above-mentioned Japanese Patent Publication No. 53-34587 is known, but this technique inevitably requires an increase in the size of the equipment that controls the guidance of the material, and also the rolling of the universal rolling mill. Since the distance from the center of the roll to the guiding device is relatively large, deformation of the material in between is unavoidable, and even if the support frame is properly adjusted, the appropriate amount of deflection of the web center is determined by the support frame. This is about 5 to 10% of the amount of movement, and there is a limit to significantly improving the dimensional accuracy of shaped steel products. In addition, the patent application
Although the technology disclosed in the specification of No. 29995 can roll highly accurate shaped steel products without increasing the size of the equipment, it is possible to roll steel sections with high accuracy, especially when a sudden load is applied to the guide at the entrance of the rolling mill. There was a risk that it would be damaged, and there was still room for improvement.

おいてはその傾向が著しい。(Function) During hot rolling of H-beam steel, during the rolling process by the vertical rolls of the universal rolling mill, the center of the width of the flange moves either above or below the bus line (corresponding to the center of the web) as shown in Figure 2. In some cases, the web is rolled with a deviation of Δh, and this causes deviation in the center of the web. A rolling method that is particularly advantageous for rolling steel sections of various sizes within the same rolling machine without requiring frequent replacement of rolls and guides, and for rolling steel sections with a constant outer width (Japanese Patent Application No. 1598-1982)
18 and Japanese Patent Application No. 63-156828), this tendency is remarkable.

Not only the vertical spacing of the guide body part 4 but also the angle with the path line can be changed individually.
Appropriate guidance can be performed according to the size of the section h to be rolled, so that deviation in the center of the web can be minimized. Here, horizontal roll 1 and vertical roll 2 when such a guiding device is installed in a finishing universal rolling mill.
The contact relationship between the vertical roll 2 and the horizontal roll 1 is such that the flange reduction begins with the vertical roll 2 and the horizontal roll 1, and then the horizontal LI-roll 1
The rolling and restraint of the shape h2 of the shape {AI1 is started by Since the correction is carried out by the guide body part 4 of the guiding device, the deflection of the web is minimized.

調整され、ここにαは(0〜2) mm程度となる。Nao, when the flange width of the section h to be rolled is B, and the vertical interval of the guide body part 4 is b, the flange h2 of the section h is passed by (b-B) as shown in Fig. 3. When the bus line moves either upward or downward, and the midpoint of the vertical interval b between the bus line and the guide main body portion 4 coincides, the maximum deviation amount is (b - B)/2. Therefore, it is important to adjust the vertical distance b of the guide main body portion 4 in advance to a value as close as possible to the width B of the section h to be rolled by the 1,000-stage elevator 5. In addition, the distance from each guide body portion 4 to the pass line varies depending on the flange width and flange thickness of the profile, but with reference to Figure 1a above, it is approximately bug = (B + α/2 ) + (0 to 3) nun
bu1 -([1 a/2)-L(0 ~ 1) mmbd

精度をより一層向上させるのに有利である。FIG. 4 schematically shows a case where the guiding device according to the present invention is applied to a universal rolling mill equipped with variable width horizontal rolls 1'. When applied to such a uniform rolling mill, by appropriately adjusting the roll width W of the horizontal roll 1, it is possible to roll a section steel with a constant outer width without the need for frequent replacement of rolls and guides, and to roll various types of steel. It is possible to reduce the relative rolling of sections of different sizes within the same rolling chance, and the large deviation of the center of the web, which was a concern when reducing the web of a section in the height direction, is avoided, which improves the dimensional accuracy of section steel products. This is advantageous in further improving the
