なわれている。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a belt conveyor type brazing belt used in a furnace.[Technical background of the invention and its problems] For assembling parts such as automobile parts and electrical parts. When performing brazing in mass production, from the viewpoint of mass production, over-brazing should be done by assembling the parts and brazing material, and brazing in a reducing atmosphere such as hydrogen gas or incompletely combusted gas should be carried out in a furnace. Furnace brazing is carried out in which the material is continuously fed, heated, and brazed.
そして、炉中ろう付けには、メツシュベルトコンベア型
ろう付は炉が多く使用されている。For in-furnace brazing, a furnace is often used for mesh belt conveyor type brazing.

ように網状に編んだものを用いている。As shown in Fig. 1, this brazing furnace is equipped with an endless mesh belt 1 for conveying the item. Brazing is carried out by transporting the product into a heating section 3 with reducing air and cooling it through a cooling chamber 4 outside of the brazing section. The mesh belt 1 is made of a metal wire 5 knitted into a net shape as shown in FIG. 2, for example.

り大変不経済であった。Conventionally, meshbel I-1 was formed using a wire made of stainless steel (8US 310, etc.) in consideration of heat resistance. However, in this case, there is a drawback that when the mesh belt 1 passes through the heating section 3 of the furnace during brazing, molten solder adheres to the wire 5 of the mesh belt 1 and the wire is likely to be melted and damaged. For this reason, Metschwert 1
An anti-adhesion agent (A4Os Ti1t M&'0 type paste) is applied to the surface to prevent molten solder from adhering. However, in this case, it takes time and effort to apply the anti-adhesion agent to the mesh belt 1, and it is not possible to reliably prevent the brazing material from adhering. In the end, the mesh belt 1 was damaged due to melting damage caused by the adhesion of molten solder, and became difficult to use in a short period of time, and the belt had to be replaced every month, which was very uneconomical.
本発明は前記事情を考慮してなされたもので、溶融ろう

Brazing provides a furnace belt that is more economical by eliminating the need for an anti-adherent coating step.

It is used to reduce wettability against corrosive wax, and has a rating of 10
% or more, the effect will be 8th place.On the other hand, considering the embrittlement of Fujo, 35% or less is preferable. Inside is 15~
30% or more preferred. Aluminum is a source of aluminum oxide, which is essential for the oxidized layer that forms on the surface of the recess, and if the content is 2% or more, the peeling effect of the molten solder will be sufficient. So clever. Furthermore, 2 to 4% is preferable. Titanium, zirconium, hafnium, yttrium, cerium, and lanthanum are 1. The oxidation layer on the surface of the material is made dense to prevent its peeling, but from the viewpoint of embrittlement of dust, it is recommended to use 2% or less, and 1% or less is recommended for oxidation.

こ付着せず、溶融ろうによる線材の溶損を防止できる。Therefore, the wire rod used in the mesh belt of the present invention has good adhesion resistance to molten solder, and has good wettability with various brazing materials (copper solder, silver solder, nickel solder, solder, etc.) under the brazing material. Since it is confusing, molten wax will not stick to it. Therefore, when the mesh belt of the present invention is used by attaching the solder wire to a furnace, the wire rod ζ melts in the furnace.
This prevents the wire from being eroded and damaged by the molten solder.
このため、線材に付着防止剤を塗布する必要がない。Therefore, there is no need to apply an anti-adhesion agent to the wire.

Is this metschbelt a series j + 5? For brazing, the wire was placed in a furnace and subjected to continuous oxidation treatment at 1200°C for 1 hour under a tetrahydrogen atmosphere with a dew point of -20°C to form an oxide film on the surface of the wire. Thereafter, brazing was performed continuously in a furnace using a copper brazing filler metal at a wet layer of 1120° C. under a CH4 incomplete combustion atmosphere (weakly reducing atmosphere). this,
As a result, Metschbelt could be used for over 3,000 hours. On the other hand, as a comparative example, stainless steel m4 (sus3
