あった。However, in the case of producing such a tandem-type carrier, in the case of a ceramic carrier, since the honeycomb body and the outer cylinder are formed separately, the honeycomb bodies are individually supported and treated one by one, and then are placed in the outer cylinder. It has to be incorporated, and there has been a problem that the number of times of carrying processing increases and productivity is inferior. On the other hand, in the case of a metal carrier, there is an advantage that the honeycomb body and the outer cylinder can be integrated at the same time, but it is difficult to incorporate a plurality of honeycomb bodies into predetermined positions in the outer cylinder, which makes the production process and production equipment complicated. There was a problem of becoming.

である。In the present invention, first, a honeycomb body 1 formed into a predetermined shape according to a conventional method is incorporated into an outer cylinder 2 and subjected to a heat treatment to provide a flat plate and a corrugated plate, and a honeycomb body outer peripheral surface and an inner cylinder. The peripheral surface is brazed with a brazing agent to produce a single-type carrier matrix 3. In addition, the production of the single-type carrier matrix 3 described above can be easily performed by the same production process using conventional production equipment as it is.

In this connection step, for example, as shown in FIG. 1, both end portions of the outer cylinder 2 may be connected by welding or the like, but by using a positioning sleeve 5 as shown in FIG. It is also possible to connect the carrier bases 3 so as to form a separated portion having a predetermined width. In addition, any connecting means corresponding to the design conditions of the metal carrier to be produced, such as providing a flange at the joint of the outer cylinder 2 and welding both flanges or connecting via a cylindrical spacer, may be used. Can be used. Next, the tandem-type carrier 4 obtained as described above is subjected to a treatment treatment with a catalytic substance according to a conventional method, thereby completing the production of the tandem-type metal carrier 6 as a final product.

Since it is 6, the interval between the respective honeycomb bodies 1 can be extremely easily finished to a predetermined size without using a special positioning device or the like. In addition, conventional single-type carrier production equipment can be used simply and efficiently for production, and, unlike ceramics carriers, multiple honeycomb bodies can be supported and processed at once, demonstrating excellent productivity. Will be done. In the above embodiment, an example of a tandem-type metal carrier composed of two honeycomb bodies has been described, but it is a matter of course that three or more honeycomb bodies can be manufactured in the same manner.
