成する方法である。 As is well known, the method for manufacturing composite structural tubes using the centrifugal thermite method involves loading a thermite agent 2 made of a mixture of a metal reducing agent and a metal oxide in a certain ratio into a main tube 1, as shown in FIG. Then, this is ignited in a centrifugal force field due to high speed rotation to cause a thermite reaction as exemplified by the formula below, and the molten metal and molten ceramic produced by this reaction heat are separated by specific gravity, as shown in Figure 2. In this method, the inner surface of the main tube 1 is coated with a desired ceramic layer 4 via a metal layer 3.

On the other hand, various thermite agents 2 other than the above-mentioned reaction system for forming the Fe--Al 2 O 3 layer can also be used.

In order to fix the main tube 1 fitted into the centrifuge metal frame 5, the insertion inversion L,
The spraying thermite agent 2a contained in the gutter 6 is sprayed by falling.

いう欠点もあつた。 However, the thermite spraying method described above has various problems, particularly when manufacturing long and small diameter pipes. First, the size of the cross section of the gutter 6 is limited by the size of the center hole 7a of the band 7,
There are cases where the gutter 6 cannot have sufficient strength. If the gutter 6 is supported in a cantilevered manner without providing sufficient strength to the gutter 6, the gutter 6 will easily bend downward due to its own weight and the weight of the thermite agent for dispersion 2a contained therein. If this deflection is large, it may become impossible to insert the band 7 into the center hole 7a. In such a case, conventionally, as shown in FIG. 4, the gutter 6 had to be inserted from both ends of the main pipe 1, requiring twice the amount of equipment and resulting in poor workability.
In addition, if the capacity of the thermite agent 2a for spraying in the gutter 6 is small, the spraying operation may have to be carried out in several parts in order to supply the required amount of thermite agent into the main pipe 1. This method also had the drawback of poor efficiency, which in turn led to low productivity of composite structure pipes.

ミツト単位体８を得る。 First, the cylindrical thermite unit 8 used in the present invention will be explained based on FIG. The cylindrical thermite unit 8 includes an outer cylinder 9 having a circular hole 9a in the center at one end and an open end at the other end;
A lid body 10 that can be attached to the opening thereof and has a circular hole 10a having the same shape as the circular hole 9a in the center, a cylinder 11 that can be easily inserted into these circular holes 9a and 10a, and an outer cylinder 9. and an encapsulated thermite agent 12 filled between the inner cylinder 11 and the inner cylinder 11. The outer cylinder 9 and the lid 10 are made of thin metal plates, and the inner cylinder 11
is made of reticulated metal material coated with a thermite agent. One example of a method for coating the net-like metal material with a thermite agent is approximately 5wt.
There is a method in which a thermite agent made into a slurry with an aqueous solution of 100% water glass is applied into the pores of a mesh metal material and allowed to dry. The application and drying may be performed at any time before the encapsulated thermite agent 12 is filled. Also,
The mesh size of this mesh metal material is preferably about 2 mm from the viewpoint of ease of adhesion of the muddy thermite agent. The length of this inner tube 11 needs to be longer than that of the outer tube 9. The reason is that the outer cylinder 9, the lid body 10, the inner cylinder 11, and the enclosed thermite agent 12
This is because it is necessary when assembling the cylindrical thermite unit body 8 using the. To describe this assembly method in detail, first, insert the inner cylinder 11 into the circular hole 9a at one end of the outer cylinder 9 from the opening side of the outer cylinder 9 until a part of the inner cylinder 11 has a length that can be bent. , cut the inserted part in an appropriate radial shape, and bend it outward at a right angle. (In this state, the aforementioned inner cylinder 11 may be painted.) Next, after filling the space between the outer cylinder 9 and the inner cylinder 11 with the encapsulated thermite agent 12, the lid 10
is fitted onto the inner cylinder 11 and attached to the outer cylinder 9.
At this time, the inner cylinder 11 must be inserted from the cap 10 to the extent that it can be bent.
The outer cylinder 9 and the inner cylinder 11 are integrated to obtain a cylindrical thermite unit body 8.

層を形成させる。 As shown in FIG. 6, a plurality of the thus obtained cylindrical thermite units 8 are inserted from one or both ends of the main pipe 1 and loaded over the entire length of the main pipe 1. In this case, it is desirable that the cylindrical thermite units 8 are brought into close contact with each other as much as possible. Next, this main tube 1 is fixed with bands 7, 7, and rotated at high speed, and the cylindrical thermite unit 8 is
The inner surface of the main tube 1 is ignited to cause a thermite reaction, and a metal-ceramic layer having a uniform thickness is formed on the inner surface of the main tube 1.
ところで、テルミツト反応を起こさせるための
着火方式として、従来は単なる花火を用いていた
が、第７図に示す如く、従来使用している花火１

包装材１５、例えば、紙・セロフアン紙等で巻き
付けた粉末テルミツト剤付花火を使用すれば、着
火の容易さの点から好ましい。 By the way, in the past, simple fireworks were used as the ignition method to cause thermite reaction, but as shown in Figure 7, the conventional fireworks 1
About 10g of powdered thermite agent 14 is added to part of 3.
It is preferable to use fireworks with a powdered thermite agent wrapped in the packaging material 15, such as paper or cellophane paper, from the viewpoint of ease of ignition.
尚、母管１としては、予め製作されたものだけ
でなく、通常の遠心鋳造により、金枠５に形成し
たものであつてもよいことは勿論である。 It goes without saying that the main tube 1 may not only be made in advance, but may also be formed in the metal frame 5 by ordinary centrifugal casting.
以上述べたように、この発明では予め作成した
円筒状テルミツト単位体８を用いるので、母管１

できる。このように、円筒状テルミツト単位体８
を用いれば、従来の樋６による散布方法の欠点は
解消される。その上、金枠５の回転の軸線方向
は、水平に限定されないという利点もある。 As described above, in this invention, since the cylindrical thermite unit body 8 prepared in advance is used, the main tube 1
A metal-ceramic layer having a uniform thickness can be obtained in the main tube 1 regardless of its length or the diameter of the tube. In this way, the cylindrical thermite unit 8
By using this, the drawbacks of the conventional spraying method using the gutter 6 are eliminated. Furthermore, there is an advantage that the axial direction of rotation of the metal frame 5 is not limited to the horizontal direction.

Approximately 4 kg between the inner cylinder with an inner diameter of 89 mm
Five cylindrical thermite units with a total length of 300 mm are filled with a thermite agent and are made of a thin steel plate with a thickness of 0.2 mm and have an outer diameter of 149 mm and are inserted into the inner and outer cylinders and attached to the caps. , outer diameter 165.2mm as the main pipe,
Thermite is sequentially pushed and loaded into a steel tube with an inner diameter of 151.0 mm and a total length of 1500 mm, and the steel tube is fixed with a band.While rotating at high speed, the inner surface of the cylindrical thermite unit is ignited, causing a thermite reaction, and forming a metal-ceramic layer. Formed on the inner surface of a steel pipe. It was confirmed that the quality of ceramic composite steel pipes manufactured using this method was equivalent to that of conventional pipes manufactured by spraying powdered thermite with a gutter, and that the manufacturing efficiency was significantly improved.
