この発明は平行フランジ溝形鋼、すなわちフラ
ンジの対向面が平行な溝形鋼の製造方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a parallel flange channel steel, that is, a channel steel whose flanges have opposing surfaces that are parallel.

出しなどの問題を生じ必ずしも良好な結果は得ら
れなかつた。 Since this type of channel steel does not have a taper formed in the flange, sufficient parallelism cannot be obtained by groove rolling, and it is generally produced by universal rolling. However, even in this universal rolling, problems such as selvage occurred, and good results were not necessarily obtained.
この発明はこのような従来の問題点を解消すべ
く創案されたもので、孔型圧延によつて高精度の
平行フランジ溝形鋼を製造し得る製造方法を提供
することを目的とする。 The present invention was devised to solve these conventional problems, and an object of the present invention is to provide a manufacturing method capable of manufacturing highly accurate parallel flange channel steel by groove rolling.

スプリングバツクを考慮した充分な整形を施す。 The method for manufacturing a parallel flange channel steel according to the present invention involves shaping the channel steel immediately after groove finish rolling by a rotatable roller that rolls into contact with at least the inner surface of the web, and then shaping the channel steel so that the outer surface of both flanges is A rotatable roller is press-contacted to the flange to bend both flanges inward for shaping rolling. Perform sufficient shaping to take spring back into consideration.
次にこの発明に係る製造方法の一実施例を図面
に基づいて説明する。 Next, an embodiment of the manufacturing method according to the present invention will be described based on the drawings.

７によつて溝形鋼２に整形圧延を施す。 1 and 2, the parallel flange channel steel 2 rolled by the groove finishing rolling mill 1, 1 is guided along the rolling line L in the outlet guide 3, and then the four rotatable rollers 4, 5, 6,
7, the channel steel 2 is subjected to shaping rolling.

る。 Here, at the stage where the channel steel 2 is finished rolled in the groove finish rolling mills 1, 1, it is sufficient to improve only the parallelism of the flanges 2F, 2F, and a very large rolling force is not required for shaping rolling. Since the channel steel 2 is sent out by the mills 1, 1 and other mills, a sufficient shaping effect can be obtained by the rotatable rollers 4, 5, 6, 7. This makes it possible to manufacture the channel steel 2 using inexpensive equipment.

を改良するための整形圧延を行う。 In the groove finishing rolling mill 1, 1, the channel steel 2 has flanges 2F, 2F widening toward the tip 2T.
Rolling with insufficient parallelism is performed, and the rotatable rollers 4, 5, 6, and 7 perform shaping rolling to improve the parallelism of the flanges 2F, 2F.

い。 The rotatable rollers 4 and 5 are rotatably supported by a shaft 8 parallel to the erecting direction of the flange 2F in the desired shape of the channel steel 2, and are rolled with a diameter gradually increasing toward the tip 2T. The surface 9 is pressed against the outer surface A1 of the flange 2F. That is, the rotatable rollers 4 and 5 perform shaping rolling to tilt the flange 2F inward, and at this time, the flange 2F is tilted inward by an amount corresponding to the inclination of the rolling surface 9 compared to the parallel state of the flange 2F. The taper of the rolling surface 9 is set to correspond to the spring back of the flange 2F, and as a result, the flanges 2F, 2F are finished in good parallelism. Note that as a method of giving an inclination to the rolling surface 9, the rolling surface 9 is formed into a cylindrical surface and the shaft 8 is set at the tip 2.
A method of inclining the flange 2F inward toward T may also be adopted. In this method, the inclination of the rolling surface 9 can be set arbitrarily, but the rolling surface 9 may be tapered and the angle of the shaft 8 may be adjusted.

11, each of which is rotatably supported by a shaft 1.
A cylindrical rolling surface 12,1 centered at 0,11
3 each. The rolling surfaces 12 and 13 are pressed against the inner surface A 2 and outer surface A 3 of the web 2W, respectively, to support the web 2W against the rolling force of the rotatable rollers 4 and 5, and to remove bending of the web 2W. . At the stage where the web 2W is rolled in the groove finishing rolling mills 1 and 1, the web 2W generally has an inner surface.
A Convex bends are generated in two directions, so shaping rolling by rotatable rollers 4 and 5 is performed on flanges 2F and 2.
It also contributes to the parallelism of F. However, since the bending of the web 2W may be eliminated by the rotatable rollers 4 and 5, the rotatable roller 7 may be omitted and the web 2W may be supported only by the rotatable roller 6. Furthermore, in order to enhance the effect of bend removal by the rotatable rollers 6 and 7, the rotatable roller 6 is formed in the shape of a beer barrel, and the rotatable roller 7 is formed in the shape of a drum, so that the web 2W is convex toward the outer surface A3 . Rolling should be carried out in such a way that

6 and 7 are arranged at the same position on the rolling line L, but if the rotatable rollers 6 and 7 are shifted in the direction of the rolling line L with respect to the rotatable rollers 4 and 5, the rotatable rollers 4, 5, 6 and 7 can be supported and adjusted more easily.
