いている。(Prior art) Generally, as a method for slit rolling steel bars, etc.
It is known, for example, from Japanese Patent Laid-Open No. 52-116762, to obtain a plurality of bars from a single material using split rolling rolls. In such slit rolling of steel bars, etc., when a roll is used to divide the rolled material by shearing and send it to the next pass, a guide device having a configuration as shown in FIG. 6 has conventionally been used.

置である。(Problems to be Solved by the Invention) The present invention does not cause seizing defects on the rolled material divided by the slit path and its guide device, and does not cause misrolling due to pushing out of the guide by the rolled material. This is a guide device for slit rolling of long steel products that enables stable rolling.

よつて曲げることを止めて、短軸方向に圧延材を

特徴としている。(Means for Solving the Problems) The present invention stops bending the oval-shaped rolled material in the long axis direction where the bending rigidity is strong immediately after the strip pass, and guides the rolled material in the short axis direction. It is characterized by being bent and expanded laterally by an improved gutter located next to the guide.

た樋で、曲げ剛性の弱い短軸方向、つまりここで

り、従来発生していた焼付疵、ミスロール等の作
業トラブルを解消した。 This is because the rolled material, which already has a twist angle, is expanded by the twist friction guide in the short axis direction, where the bending rigidity is weak, in the next improved gutter, that is, in the horizontal direction in the drawing. This eliminates work problems such as seizure defects and misrolls that previously occurred.
第１図に本発明のガイド装置を示す。 FIG. 1 shows a guide device of the present invention.

る。 After the rolled material 10 is divided by a slit path a having a groove inclination θ 0 of approximately 10°, it is separated from the roll 15 only in the upward and downward directions by a twist friction guide 11 . The rolled material 1 is transferred to the next gutter 12 while increasing the twist angle θ 1 using the twist friction guide.
Guide 0-1 and 10-2 and spread them to the left and right.

４を経て、次パスｂへ送り込まれる。 At this time, since the rolled material already has a torsion angle θ 1 =15° or more, the rigidity in the left and right directions is weak, and therefore the frictional force is light and no seizure defects occur. The rolled material exiting the gutter 12 is transferred to the entrance guide 1 of the next pass, as in the conventional case.
Roller guide 1 attached to the tips of 3 and 13
4, and then sent to the next pass b.

第１図のツイストフリクシヨンガイド１１を改
良した具体例を第３図、第４図に示す。 A specific example of an improved twist friction guide 11 shown in FIG. 1 is shown in FIGS. 3 and 4.

視Ａ−Ａ及び視Ｂ−Ｂをそれぞれ示す。 This corresponds to the configuration in which rollers 16, 16 are arranged on the exit side of 11 in FIG. Since the roller is located at the fulcrum that separates the rolled material to the left and right in the gutter 12, the rolled material is separated smoothly. Further, after the bar passes through the rollers, the rollers hold the rolled material, so that contact between the rolled material and the twist friction guide is eliminated, and wear and seizure can be prevented. 3 is a front view, FIG. 4 is a plan view, and FIG. 5 is a view AA and a view BB in FIG. 3, respectively.

Two inlet ends may also be provided. In the case of multiple slits such as 3 or 4 slits, a guide device having the same structure as the above-mentioned case of 2 slits is constructed.

生じていた。(Effect of the invention) In the conventional method, seizure occurred in the friction guide part, causing defects in the rolled material and misrolls caused by the rolling material being bumped, so rolling was stopped for about 20 minutes and the seizure was removed by cleaning the grinder. It was removed by This frequency was 2 to 5 times per shift. Furthermore, even with such care, misrolling occurred about once per shift, resulting in a large loss in rolling efficiency.
