A bend occurs locally by c1. As a method for straightening such bends in shaped steel, several roller straightening rollers 4 arranged in a staggered manner are used.
One effective method is to apply a bending moment to the shape by bending the entire length of cedar or paulownia through the rice field, thereby correcting the bend.

がある。In addition to this method, there is a method of press striping, etc., in which the shape of the cedar is cut as appropriate using a pusher metal fitting, depending on the initial bending shape of the shaped steel.
その他水冷方法、圧延温度制御卸方法、圧延制（作方法
等が提案されている。Other proposed methods include a water cooling method, a rolling temperature control method, and a rolling method.

This is because the bending moment y cannot be applied to the unsteady part because the bending range is 41JLl~1bLILl. This is also an essential drawback of the roller surface construction method.

いる。25 To summarize the first idea of the method of the present invention, this idea is to measure the bending of the section steel before fA +E using the bending C rule appendix 6, and to measure the bending of the section steel before fA +E, and to person 1
Rolling @i on at least one side of the rule and exit side
The process consists of: straightening the shape and bending of the steady part with the shape steel roller straightening machine 1 and geometry 1, and straightening the bending of the unsteady part of the shape steel with the E rolling straightening machine 2. There is.

The first rolling straightening machine 20 is provided on the entry side of the roller straightening surface 10, and the second rolling straightening machine 2 is provided on the exit side of the roller straightening machine 1. There is. So far,
Although there is a gap with that shown in Figure 1 C), there is a change in the following structure. In the pre-erosion shape, the i- bend is the first bend + t411 with the leggear 6a? Measure.
