【発明の属する技術分野】本発明は、鉄鋼製品の接合に
適用されるろう付方法に関する。TECHNICAL FIELD The present invention relates to a brazing method applied to joining steel products.
【０００２】[0002]

いた。2. Description of the Related Art Conventionally, various brazing filler metals have been used, but those whose components are adjusted to have a relatively low melting point are used. The brazing material may have a foil shape, a powder shape, or the like, but the brazing material adjusted to a predetermined component was once dissolved and manufactured.

った。There is no problem when brazing with a commercially available brazing material, but when developing a brazing material with a new composition, the composition of two or more kinds of materials is strictly adjusted, and melting, casting and rolling are performed. It takes time because the brazing filler metal is made through such steps. In addition, if the components are misaligned, there is a problem that they do not dissolve at a predetermined temperature, or some dissolve but a residue remains.

【課題を解決するための手段】本発明は上記課題を解決
するため次の手段を講ずる。The present invention employs the following means to solve the above-mentioned problems.
【０００５】すなわち、ろう付方法として、真空チャン

ろう付材を上記共晶反応を起す温度以上に加熱し、溶融
ろうを上記注入開孔からろう付部へ流出注入する。That is, as a brazing method, a material to be brazed and a crucible with an injection opening facing the brazing portion of the material to be brazed are arranged in a vacuum chamber, and a plurality of eutectic reactions are carried out in the crucible. The above materials are mixed and charged, the crucible and the material to be brazed are heated to a temperature higher than the temperature at which the eutectic reaction occurs, and molten braze is flown out into the brazing portion through the pouring opening.

共晶温度以上に加熱されると、共晶温度は個々の材料の
融点より低いので、相互の接触部が共晶し溶融する。溶
融したものはるつぼの注入開孔から流出し被ろう付材の
ろう付部に注入され、ろう付される。In the above, when a plurality of materials that undergo eutectic reaction are heated above the eutectic temperature, the eutectic temperature is lower than the melting point of each material, so that mutual contact portions are eutectic and melt. The molten material flows out from the injection opening of the crucible, is injected into the brazing portion of the material to be brazed, and is brazed.
【０００７】共晶しなかった材料はるつぼ内に残渣とし
て残り、流出しないのでろう付の障害にならない。The non-eutectic material remains in the crucible as a residue and does not flow out, so that it does not hinder brazing.
【０００８】このようにして、従来のようにあらかじめ
ろう材の成分濃度を調整する必要がなく、極めて簡便に
ろう付ができる。In this way, it is not necessary to adjust the component concentration of the brazing material in advance as in the conventional case, and brazing can be performed very easily.

融点が９６０℃、Ｃｕは融点が１０８３℃であるが、こ
の２つが反応すると融点が７８０℃の低融点の合金を生
成する。As the brazing material 3, a plurality of materials that cause a eutectic reaction are used, for example, Ag and Cu are used. Although Ag has a melting point of 960 ° C. and Cu has a melting point of 1083 ° C., when these two react, a low melting point alloy having a melting point of 780 ° C. is produced.
【００１２】このような状態のものを酸化しないように

め、ろう付がなされる。When the heater 5 is heated to 800 ° C. in the vacuum chamber 4 so as not to oxidize such a state, Ag and Cu undergo a eutectic reaction to cause a composition having a melting point of 800 ° C. or less, that is, Ag-- 23% Cu and Ag-32%
A portion of the composition between Cu is melted, flows out from the injection opening of the crucible 2, fills the brazed portion a of the brazed materials 1a and 1b, and is brazed.

従ってろう付の障害にはならない。That is, as shown in FIG. 4, the eutectic temperature T 1
When heated at, the material between C and D undergoes a eutectic reaction and dissolves. A
between g100% and Ag-23% Cu, and Ag-32
The composition between% Cu and Cu 100% has a melting point higher than 800 ° C. and therefore does not melt, and remains in the crucible 2 as a residue.
Therefore, it does not hinder brazing.
