ある。2. Description of the Related Art As an example of H-shaped steel, a shaped steel is a material such as a bloom, a beam blank or a slab, which is formed into a sectional shape as shown in FIG. 9 in a continuous casting or slabbing process.
After being placed on a hot rolling line having an arrangement as shown in FIG. 8 and heated in a heating furnace 1 to a temperature suitable for rolling, a rough rolling mill 2, a rough universal mill group consisting of one or more universal mills and an edger mill 3. Generally, it is manufactured by a so-called hot forming process in which hot rolling is performed by the finish universal mill 4 and subsequently cut into a predetermined length by a hot saw.

なっている。On the other hand, particularly in the production of large-sized H-section steel, three plate materials or coil materials are set in H or I shape and their corners are welded, welded, and crimped (hereinafter collectively referred to as "welding"). The so-called cold forming process is generally adopted. By the way, in the assembly of a building structure in recent years, use of an automatic welding machine or the like is indispensable for mechanization and labor saving of welding work, and a small size (web height ≦ 4
For H-section steel with a diameter of 00 mm and a flange width of ≦ 200 mm, the requirement for dimensional accuracy is particularly severe as shown in FIG.

らざるを得なくなってきた。However, in the hot forming process, there are limits to the cross-sectional dimension accuracy of shaped steel products due to factors such as equipment configuration accuracy and rigidity, control accuracy, and metal flow of hot material, and the accuracy required by users is limited. Since it is difficult to obtain, it has become obligatory to rely on a cold forming process that easily ensures high dimensional accuracy, that is, a welded H-section steel manufacturing process in which three plate materials or coil materials are welded.

Reference numerals 20 and 21 denote upper and lower rolls and rolls for rolling down the plate material 13 for the web conveyed in a state where the width of the web plate material 13 is conveyed vertically, and 22 and 23 are width end portions and central portions of the plate material 13 for the web. Are an end restraint roller and a central restraint roller for restraining each of them. The web plate material 13 is formed by this processing step (called a web-up set) from a rectangular cross section to a dogbone-shaped cross section in order to increase the crimping area with the flange plate material 12 as shown in FIG. It is sent to the welding machine 15.

The vicinity of the central part of the is heated to 1200 to 1350 ° C. for pressure bonding. The H-section steel 5 weld-formed into the I-shape in this way
Is straightened while sequentially passing through a vertical straightening machine 16 and a horizontal straightening machine 17. The problem derived from the above manufacturing process is that when the web is set up, the dogbone shape is
As shown in Fig. 3, it is easy to have irregular shapes such as one-sided blistering, asymmetry, falling and buckling. This disordered shape is
It makes the strength of H-section steel unstable and impairs its aesthetic appearance, so it is disliked.

The "restraint guide roller replacement system" is used to replace the above according to the web plate width (web height) H 1 . However, this method
Due to the large number of product sizes, that is, web heights, replacement frequency is high and 2 per replacement (recombination)
Since it takes as long as 0 to 30 minutes, productivity is hindered, many workers are required, and the equipment cost is high.
