However, in the case of such conventional θ-, ■ The cross-sectional area of the material is large, and therefore a long heating time is required during rolling VC, resulting in a large heating furnace, which reduces energy consumption and reduces pollution. The cost would be enormous; ■ Because molding requires high pressure, it is extremely difficult to form a shape of tin with low deformation resistance and low deformability, such as various stainless steels. ■ The unit weight of the material is low. It is limited by the rolling length and furnace internal dimensions, and the amount of cut-off per roll increases, resulting in poor yields. ■ Many roll-related ancillary equipment and parts are required;
There is a lot of setup loss time due to hole changes and size changes. ■ Not only does it take a lot of time to change the holes and rolls in each stand for each product size, but these changes are easy (because there is no C, rolling The actual operating rate of the equipment is extremely low, and the number of required rolls increases, increasing roll costs.

(2) When replacing holes or changing rolls, defects in the hole shape or poor cenoting of each stand can easily occur, resulting in slight variations in product shape. ■ Since there are many bath processes, the final temperature of rolling is low, so recrystallization cannot be performed at that stage, so heat treatment is required after rolling is completed.■ Rolled surface and shape It is easy to cause variations in the temperature, and if heat treatment, straightening, shot blasting, pickling, etc. There were problems such as the need for the L process, and the current situation was that no one in the prefecture had a solution.

By the way, if you recognize the problems with the conventional shape I/1 manufacturing method, by using a plate as the starting material when manufacturing the shape, you can immediately reduce the amount of reduction and the number of baths. There is a risk of falling into the illusion that the desired product will be completely reduced, but even if you try to manufacture a profile from a plate-shaped material, the reduction required due to the thin wall thickness
Therefore, it is generally considered that it is impossible to obtain a product with the correct shape 4), which is completely filled with flesh up to the top corner, which is the most distinctive feature of hot-rolled shapes. In fact, there have been no reports to date on the complete production of shapes from plate-like materials.

However, although it has been practiced for some time to produce angle lays using the so-called cold roll forming method as a starting material for sheet materials, this method is limited to thin-walled materials with good formability. Since only bending is performed without substantial rolling reduction, the apex corner of the 4D angle is rounded, making it impossible to obtain a product with sharp edges such as hot-rolled sections. It was something.

By strictly controlling the rolling/D preforming hole type, rolling temperature, rolling reduction rate, and rolling speed within specific ranges, and by controlling the force and overall L', the deformation resistance is relatively high.
Even if the material is a material such as stainless steel, which has a deformability of less than 7 degrees, for example, it is made of plate-shaped material such as a strip of slit to the required width, and has a finished hole shape. 2-bath rolling including
It is possible to continuously obtain an accurate shape of the material until the material has been fully formed.In addition, by fully utilizing the direct annealing phenomenon, good texture properties can be achieved without any special heat treatment after forming. This led me to the unexpected discovery that it is possible.

(b) Rolling Temperature In the rolling of angle-shaped materials, it was previously thought that a ball rolling section of 1 degree would result in better pin angle filling properties, but when a plate material is used as the starting material, When the temperature is too high, the coefficient of friction decreases and the linaceae is in the stretching direction! It will extend and will no longer fill the tip of the apex corner of the 4L4J shape, and the corner of the nozzle pin. If the total rolling temperature is 1000° C. or less, such inconvenient noise will not occur. On the other hand, when the rolling temperature becomes less than 8 s o ℃ and 1 jiii, the flow of the material in the pin angle direction stops and the pin angle is not filled as expected.1-1 After the completion of rolling Direct annealing effects cannot be expected.

1. If the product is 3mm thick, which is one of the thinner rolled Yamagata products actually used,
It is possible to sufficiently fill the bin with a bin angle of IR4 by simply adding a cumulative reduction rate of more than 100 mL, and it is possible to finish the bin with 2 baths Gτ. Of course, as the thickness of the product plate increases, a higher reduction rate is required, but the relationship is as shown in FIG.
