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.
