題がある。(Problems to be Solved by the Invention) As shown in Fig. 6, the method of manufacturing a clad steel plate by placing the laminated material 2 on the base material l and performing roll rolling etc. is simple, but Since they are not bonded, there is a large difference in elongation between the base material and the composite material at high temperatures, so it cannot be applied to the production of titanium clad steel sheets. When the base material and the composite material are stacked and welded directly from the periphery or top of the two, this results in dissimilar metal welding.For example, if the composite material is titanium, brittle intermetallic compounds TiC, TiN, and TiFe are generated in the welded area, making it difficult to ensure the welding. do not have. The method of integrating the base material 1 and the mating material 2 by performing ultra-high power electron beam welding 10 as shown in FIG. 7 cannot be applied to the production of titanium clad steel plates, as described above. Although it appears to be a simple method, there are problems in that it is expensive in terms of equipment and cannot be applied to the production of long or wide clad steel plates. Figure 8 shows a method that does not involve welding dissimilar materials. However, if you simply place the contact plate 7 on the side of the base material 1 and weld the edges, the pressure during reduction will increase because the contact plate is not in close contact with the side surface. This method cannot be applied to the production of clad steel plates, as the plate cannot withstand the pressure and is certain to peel off.As a result, the plate gets caught on the rolling rolls and the rolls stop rotating, so rolling has to be stopped. The biggest problem with this method is that it requires a step of applying a release agent to form a sand-inch shape, and when the laminated material is titanium, it is difficult to fix the laminated material.

ブを提供するものである。The widely known explosive pressure welding method uses the instantaneous high pressure associated with the explosion of gunpowder, but in practice, the equipment is expensive, safety measures must be taken, and it is easy to use in terms of noise pollution. Moreover, the use of explosives limits the dimensions that can be manufactured, so it cannot be applied to the production of long or wide clad panels, and the instantaneous high pressure associated with explosive explosions is used, making it difficult to manufacture thin plates. There is also the problem that it cannot be applied to the production of clad steel plates. The present invention was made in order to solve the problems in the all-around seal welding process of the rolled slab manufacturing method, and it is possible to roll the all-around seal welded part firmly and without defects in a short time using relatively simple equipment and method. It provides slabs.

組み立てる。An example of the slab assembly order in the present invention will be explained. First, a thin plate of low carbon steel with a slightly smaller area than the base metal is placed on top of the base metal in order to reduce carburization from the base metal into the rolled joint. Next, place a laminated material of the same size on top of it, and at this time create an inert gas atmosphere in the gap between the base material and the laminated material. After that, as shown in FIG. 1, a cladding steel 3 having an angular cross section is attached to the side surface of the laminated material 2 so that the surface of a cladding portion 5 having the same composition as that of the laminated material 2 is brought into close contact with the side surface of the laminated material 2.

よい。If the dimensions of the clad steel that is brought into close contact with the side surface of the laminated material are the same width as the thickness of the laminated material, a part of the cladding portion 5 of the craft steel 3 may be cut out to form a groove as shown in Fig. 2. Alternatively, as shown in FIG. 3, the shoulder portion of the laminated material 2 may also be cut out to form a bevel. Of course, only the shoulder portion of the laminated material may be cut out to form a bevel. Furthermore, if the width of the clad steel 3 is around the thickness of the laminated material 2, seal welding 6 around the fillet may be performed as shown in FIG.
溶接方法としては合わせ材がチタンの場合、合わせ材と
クラッド表面との全周シール溶接はガスシールドアーク
溶接で行う。ステンレス鋼の場合はガスシールドアーク
溶接あるいは潜弧溶接、手溶接のいずれでもよい。As for the welding method, when the laminated material is titanium, the entire circumference seal welding between the laminated material and the clad surface is performed by gas-shielded arc welding. In the case of stainless steel, gas shielded arc welding, submerged arc welding, or manual welding may be used.
合わせ材の側面に密着させたクラッド鋼の炭素鋼あるい

ーステナイト系の時はオーステナイト系の博打を用いる
し、フェライト系の時はフェライト系の博打を用いる。Full-circumference seal welding of the carbon steel or low-alloy steel part of the clad steel that is in close contact with the side of the cladding material and the base material made of carbon steel or low-alloy steel requires gas-shielded arc welding regardless of whether the cladding material is titanium or stainless steel. Welding, submerged arc welding, or manual welding may be used. Welding of the laminated material and the cladding surface uses the same type of components as a gamble. For example, when the laminated material is titanium, titanium or titanium alloy is used. In the case of stainless steel, if the laminating material is austenitic, an austenitic material is used, and if it is ferritic, a ferritic material is used.
クラッド鋼の炭素鋼あるいは低合金鋼の部分と炭素鋼あ
るいは低合金鋼からなる母材との溶接は、いずれの場合
も同じレベルの博打を用いる。Welding a carbon steel or low alloy steel part of the clad steel to a base material made of carbon steel or low alloy steel uses the same level of gambling in either case.

たは同時に行ってもよい。As for the welding order, the full circumference seal welding between the carbon steel or low alloy steel part of the clad steel and the base metal of the slab, and the full circumference seal welding between the cladding material and the clad surface, can be done first or at the same time. good.

不足を補う方法があるが、この方法によると最終的には
製品価格にはねかえるので好ましくない。When the mating material is stainless steel, dissimilar metal welding of stainless steel and carbon steel or low alloy steel is generally possible, but tiffi is not used in parts where mechanical performance is important. This is because cracks occur internally due to a lack of ferrite in the weld metal. If hot rolling is performed while cracks have occurred inside, the cracks may not be able to withstand the rolling pressure and the cracks may open, causing the base material and the mating material to separate. One way to prevent the occurrence of cracks is to compensate for the lack of ferrite by using a high-grade welding material, but this method is not preferred because it ultimately increases the product price.

本発明の効果を実施例によりさらに具体的に説明する。From the above, by using the same type of ingredients through square clad steel, no cracking occurs and the product price can be reduced. After completing the assembly and welding in this manner, hot rolling is performed to obtain clad steel. The fifth method for assembling slabs using square clad steel is
As shown in the figure, the side surface of the cladding steel 3 is brought into close contact with the side surface of the laminating material 2, and the cladding portion 5 having the same composition as the laminated material of the cladding wJ3 is seal welded all around, and the base material 1 and It is also possible to seal-weld the entire circumference of the carbon steel or low-alloy steel part of clad steel 3, but this method is not recommended because the joint surface of the clad steel cannot withstand the high pressure during hot rolling and will peel off. Should not be used. The effects of the present invention will be explained in more detail below using Examples.

第２図におけるクラッド鋼は縦・横１＝１の比で合わせ

否を判断した。Table 2 shows the assembly method used. As a comparative example, a method other than the present invention is shown in FIG. 6, in which a laminated material is simply layered on top of the base material (this is referred to as method A), and a method shown in FIG. Two methods were used as comparative examples: a method of applying a plate and rolling (this method is referred to as method B). The criteria for determining whether or not titanium clad steel could be manufactured was determined.

本発明はチタン以外の他のクラッド鋼にも適用できるの
は当然である。The slab constructed by the clad steel adhesion method of the present invention could be hot rolled without any problems, and a good titanium clad steel could be obtained. Method A, which was used as a comparative example and involved rolling with only a laminated material layered on the base material, failed to obtain titanium clad steel because the base material and the laminated material deteriorated after hot rolling. In addition, hot rolling was discontinued in method B, in which a contact plate was applied to the side surface of the product, because the contact plate peeled off during rolling and got caught in the rolls. The above is an example of titanium,
It goes without saying that the present invention can be applied to clad steels other than titanium.
