物にあっては非常に高価につく。Background of the Invention: Clad steel has recently become known as a metal plate made of a composite of different metals. This clad steel (
Generally, laminated plates of carbon steel and stainless steel) are manufactured by rolling the base material carbon steel and stainless steel, for example, in a non-oxidizing atmosphere, rolling them together, and bonding them together, and are usually made from thin sheets. The finished products are provided to customers. However, due to demand, thick products such as structural materials are not manufactured, and even if they were manufactured, long items would be extremely expensive.

。That is, in the present invention, a flat steel material at a rolling temperature is formed by forming a plurality of grooves with rounded bottoms at the groove forming pitch to be obtained in the first rolling process, and forming shallow narrow grooves at the top between the grooves. In the second rolling process, the bottom of the groove is widened and deepened, the width of the protrusion formed in the previous process is narrowed, and a narrow groove at the top is formed in the V-beam steel. Then, in the third step, the V-shaped groove at the top of each ridge is made deeper and the width of the base material is adjusted, and in the finishing step, the ridges on both sides formed by the V-shaped groove at the top of the ridge are made into grooves. This is a method of forming flat steel having a plurality of grooves on one side of the flat steel whose inner pockets are wider than the openings by pushing down the groove so that the opening width at the upper part of the groove is narrower than the inner lower part.

First, form the required number of grooves with a roll with protrusions,
This groove-shaped portion is sequentially enlarged by rolling forming rolls so as to obtain the inner diameter of the required groove, and at the same time, the portion that will become the protruding confinement portion for narrowing the opening of the required groove is raised and formed. After passing through the stage forming rolls,
Using finishing rolls, the flat steel is width-aligned and the protruding ridges, which are raised on both sides of the groove forming part, are displaced to the upper part of the groove to narrow the opening and form a slit part of the desired shape. This makes it possible to manufacture a flat steel with a groove whose inner pocket is wider than the opening.

る。FIG. 1 is a perspective view of a specific example of the grooved flat steel obtained by the method of the present invention.
In order to obtain 1), first, a flat steel material αO heated to a rolling temperature is passed through a rolling mill as shown in FIG. 2, and the dimensions are adjusted in the first step. Next, in the second step, the lower roll ■ has a flat groove-shaped caliber product that receives the material αO shaped in the first step, and the upper roll has a required number of protrusions 02 for forming grooves. 0◇, as shown in Fig. 3, put the material 00 into the caliber product of the lower roll (to), and then transfer the material 00 to the upper roll 0.
Push the protrusion (to) of ■ into the V-shaped groove α
Form B. At this time, protrusions α field having a trapezoidal cross section and a thin and shallow groove at the top are formed on both sides of the 8-groove forming portion. Of course, both ends are partially overhanged so that the material can escape when the protrusions (to) of the upper roll 0) are pushed in.
このようにしてＶ形消を形成したものを、次の第３工程

寸法に押し拡げられる。When moving to the fourth step, the lower roll (end) is again equipped with a flat groove-shaped caliber product, and a protrusion with a triangular cross section is added to make the V-shaped groove α6 at the top of the protrusion α3 on the workpiece side larger. The upper roll (T) formed in a narrow caliber product is used to form the product as shown in Figure 5. In this process, the width of the workpiece is expanded to the required size.

（２）を複数条配列された平鋼製品（１）が得られる。The workpiece with the protrusions formed on both sides of the groove part α in this way moves on to the final finishing process, where it is pinched by flat upper and lower rolls (towards) to form the protrusions. The local part of the ridge α is crushed and displaced onto the groove αD, and the protrusion α3 portion with the protrusion Q4 is generally pressed, so that the bottom of each groove αυ is also filled in the center. As a result, a flat steel product (1) having a plurality of rounded inverted Y-shaped grooves (2) arranged as shown in FIG. 6 is obtained.
これら全工程は一連の圧延により、順次連続して行われ

It is integrally provided according to the groove (2) spacing of 1), and its leg C?
]) can be inserted through the opening of the groove (2) and has a dimension longer than the depth of the groove in an untreated state, and such an aluminum plate and the grooved flat bar (1) obtained by the present invention are combined. Combine, apply pressure to the aluminum plate (A) and attach the legs.
If υ is buckled or the lower end of the leg is split in half and expanded to the left and right, the leg 21) will deform inside the groove (2) and the aluminum plate and flat steel will become integral. A composite plate is obtained in which a relatively thin aluminum plate is reinforced with flat steel.
