The mainstream is one that supports alumina powder. However, these ceramic honeycombs have a high exhaust resistance, and their use temperature is low due to the heat resistance of the stainless steel mesh inserted between the honeycomb and the outer cylinder to prevent the honeycomb from breaking. There were drawbacks such as restrictions on

Stainless steel, which has good oxidation resistance, is used, and the flat steel plate of the honeycomb body and the corrugated steel plate are made by selecting a rational joint position and performing sufficient joint management to ensure a secure joint. It is important to avoid adhesion of excess brazing agent, which will reduce corrosion resistance.

The method for manufacturing the support matrix is to first apply a liquid binder for fixing the brazing agent to either a flat or corrugated steel plate, and then to sprinkle a granular brazing agent or a pasty brazing agent. A method of forming a honeycomb body by coating a flat steel plate and a corrugated steel plate by alternately stacking them and winding them has been disclosed.

In addition, it is necessary to braze a wide area, and the brazing agent adheres to unnecessary areas.
This is not preferable as it leads to a decrease in corrosion resistance. Furthermore, with this method, it is difficult to confirm the position where the brazing agent is to be fixed, which poses a problem in ensuring that the required locations are brazed.

In the method of winding to form a honeycomb body and heating and brazing, a brazing agent 17 is supplied between a flat steel plate 12 and a corrugated steel plate 11, as shown in FIG. 8(a). When heating is performed for brazing in this state, the brazing agent melts and flows out or contracts as shown in FIG. In addition to being defective, this is also undesirable as it causes damage and noise due to vibration.

This is based on the knowledge that brazing can be carried out extremely advantageously by specifying the timing of coating and the subsequent timing of supplying particulate brazing agent.

ムの破損、騒音の発生等を防止することかできる。That is, before a flat steel plate and a corrugated steel plate are layered and rolled to form a honeycomb body, a liquid binder for fixing the brazing agent is first applied to either the flat steel plate or the corrugated steel plate. Thereafter, a flat steel plate and a corrugated steel plate are stacked and rolled to form a honeycomb body, and then particulate brazing agent is supplied from one end of the honeycomb body. When the brazing agent is supplied in this way, the flat steel plate 12 and the corrugated steel plate 11 come into contact with each other, as shown in FIG.
The brazing agent 17 adheres to the vicinity of the contact point 19, and since there is no brazing agent between the flat steel plate and the corrugated steel plate at the contact point, the flat plate 1 remains even when heated for brazing.
There will be no gap between the corrugated steel plate 11 and the corrugated steel plate 11, and no bonding defects will occur, thereby making it possible to prevent damage to the honeycomb, generation of noise, etc., caused by this.

パターンに対して本方法は極めて有効である。Furthermore, in the method of the present invention, before the flat steel plates and the corrugated steel plates are alternately stacked or wound to form a honeycomb body, a liquid binder for fixing the brazing agent is applied to the flat steel plates or the corrugated steel plates. Brazing can be applied to the required locations, the position where the brazing agent is to be fixed can be selected arbitrarily, and the application status can be monitored, and suitable brazing is extremely advantageous in obtaining a joint pattern. It is. In other words, the braze joint pattern of the honeycomb is extremely important in producing a durable honeycomb body, and in order to produce a honeycomb body with sufficient thermal fatigue resistance, the flat steel plate and the corrugated steel plate inside the honeycomb body are very important. The methods include brazing all the contact points of the processed steel plate, brazing only the contact points near both ends, brazing the contact points at specific internal parts,
Continuous or intermittent brazing methods or a combination of these methods may be considered, but this method is extremely effective for these various brazing joint patterns.

A coating head consisting of a liquid binder coating roller, nozzle, brush, etc. can be used to apply the liquid binder to the steel plate, but it is necessary to have a mechanism that can control the movement of this coating head in a direction transverse to the traveling direction of the steel plate. Alternatively, instead of a movable coating head that can be controlled, a method in which multiple sets of coating heads adjusted to each coating pattern are fixedly arranged in the advancing direction of the steel plate can be used to control the coating position of the liquid binder according to various brazing patterns. can be controlled. Furthermore, it is also possible to apply the liquid binder in the required pattern by hand application using a brush or spray.

In FIG. 1(a), a liquid binder is applied to the top of a corrugated steel plate 11 from a liquid binder supply tank 13 via a suction roll 14 and an application roll 15.
After that, the honeycomb body 16 is rolled up together with the flat steel plate 12.
is produced. In addition, FIG. 1(b) is similar to FIG. 1(a), but in this figure, after a liquid binder is applied to a flat steel plate 12 in the same manner as described above, a corrugated steel plate 11 is applied. A honeycomb body 16 is formed by rolling them up one on top of the other.

な個所へのろう剤の付着をより低減することができる。The liquid binder can be suitably applied to either a corrugated steel plate or a flat steel plate according to a required brazing pattern, and the above-mentioned coating method can be used. When coating a flat steel plate, it is applied intermittently in accordance with the wave pitch of the corrugated steel plate. More preferably, a liquid binder can be applied to the top of the corrugated steel plate. In other words, when this is formed into a honeycomb body and the brazing agent is supplied, the brazing agent is fixed near the contact area between the corrugated steel plate and the flat steel plate, so the brazing agent is not applied to unnecessary areas. Adhesion can be further reduced.

へのバインダーの供給量などを調整する必要がある。Various liquid plastics such as polyvinyl alcohol can be used as the liquid binder, but care must be taken to prevent the applied binder from flowing to unnecessary areas after application.
Also, select the type and concentration of the binder so that the binder is applied uniformly. In addition, when applying by spray or brush, adjust the jetting pressure, contact pressure of the brush, etc. so that the liquid binder is applied uniformly, and when applying the liquid binder with a coating roll, adjust the pressure between the coating roll and the steel plate. It is necessary to adjust the pressing strength and the amount of binder supplied from the suction roll to the application roll.

Unnecessary brazing agent adhering to areas where the liquid binder is not attached can be easily removed by intermittent vibration or compressed air. As a result, the brazing agent is supplied only to the areas where the liquid binder has been applied (the shaded area in FIG. 2) as shown in FIG. In this case, there is no waxing agent involved, and the waxing agent is fixed around the area. Furthermore, by applying a liquid binder near the top of the corrugated steel plate as described above, the brazing agent is fixed only near the top, making it possible to reduce the amount of brazing agent used. and,
The influence of the brazing agent on the steel plate can be minimized.
