材を溶融させて接合部材を接合するもので、溶融フラッ
クスはその本来の役割であるフラックス効果の他に無酸
化加熱雰囲気と無酸化加熱媒体を構成するものである。(B) Background Art Conventional immersion brazing generally involves melting a flux consisting of fluorides such as sodium chloride, potassium chloride, lithium chloride, and aluminum fluoride in a refractory tank, and then attaching the assembled brazed members to the melt. Immerse it in the liquid,
The joining parts are joined by melting a brazing filler metal that has been clad or placed in advance at the joining part.In addition to its original role of flux effect, the molten flux forms a non-oxidizing heating atmosphere and a non-oxidizing heating medium. It is something to do.
これらのことから、浸漬によるろう付け接合方法は、加
熱炉によるろう付け法等に比して昇温速度が早くかつ均
一加熱が容易で、ろう付けの信頼性が高いという特徴を
有している。For these reasons, the brazing joining method using immersion has the characteristics of a faster temperature rise rate, easier uniform heating, and higher brazing reliability than brazing methods using a heating furnace. .
ところが、ろう付け温度と整合するフラッグス溶融温度

クス（塩化ナトリウム、塩化カリウム、塩化リチウム、
フッ化物など）は潮解性が強く、鋼や銅などの金属を強
く腐食し、また導電性であるので電気機器の絶縁を破壊
する欠点がある。However, fluxes (sodium chloride, potassium chloride, lithium chloride,
Fluorides, etc.) have strong deliquescent properties and strongly corrode metals such as steel and copper, and because they are conductive, they have the disadvantage of destroying the insulation of electrical equipment.
フラックスの潮解性は、ろう付け温度の５８０〜６２０
℃においても、スラックス中に水分が存在してアルミニ
ウムを激しく酸化させ、ろう付けを阻害する。The deliquescent property of the flux is 580 to 620 below the brazing temperature.
Even at ℃, moisture is present in the slacks and violently oxidizes the aluminum, inhibiting brazing.
このため、溶融フラックスはあらかじめ表面の浄化され
たアルミニウム板をフラックス中に浸漬して水と反応さ
せ、水素と酸化アルミニウムとして脱水する必要がある
。また、溶融フラックスは長時間にわたる空気との接触
が避けられず、脱水作業を繰り返し行なう必要がある。For this reason, it is necessary to immerse an aluminum plate whose surface has been purified in advance in the molten flux to react with water and dehydrate it into hydrogen and aluminum oxide. Furthermore, the molten flux cannot avoid contact with air for a long period of time, and it is necessary to repeatedly perform dewatering operations.
しかも、脱水作業でできた酸化アルミニウムなどの沈殿
物の除去作業も欠かせない等の問題があった。Furthermore, there were other problems such as the necessity of removing precipitates such as aluminum oxide produced during dehydration.
（ハ）発明の開示
本発明は、潮解性のないフラックスによる浸漬ろう付け
法を提案するものである。(C) Disclosure of the Invention The present invention proposes an immersion brazing method using a non-deliquescent flux.
即ち、本発明は潮解性を持たない塩化バリウム（Ｂ ａ
ｃ１２ ）、塩化ナトリウム（ＮａＣＭ）ならびに塩化
カリウム（ＫＣｌ）を主とし、これにフッ化物を加えて
、化学活性化のあるフラックスとしたものである。That is, the present invention uses barium chloride (Ba
c12), sodium chloride (NaCM) and potassium chloride (KCl), to which fluoride is added to create a chemically activated flux.
例えば、Ｂａ０文２ 、ＮａＣｕ及びＫＣＩＬ７）重量
比がそれぞれ５４．７ ： １８．０ ： ２７．３
の共融塩の融点は５４０℃である。またアルミニウム
硬ろうのＡｎ−３ｉ基合金の溶融温度が５６４〜５８０
℃であり、ろう付け作業温度が５８０〜６１５℃である
ことから、上記共融塩の溶融温度の５４０℃はアルミニ
ウム又はその合金のろう付けフラックスとして適当であ
る。For example, Ba0bun2, NaCu and KCIL7) have weight ratios of 54.7: 18.0: 27.3, respectively.
The melting point of the eutectic salt is 540°C. In addition, the melting temperature of the An-3i-based alloy of aluminum hard solder is 564 to 580.
Since the brazing temperature is 580 to 615°C, the melting temperature of the eutectic salt of 540°C is suitable as a brazing flux for aluminum or its alloy.
また、フラックスの化学的活性化のために、フッ化物例
えばフッ化アルミニウム（Ａｆｌ、Ｆ３）やフッ化ナト
リウム（ＮａＦ）などを混合するが、この場合に混合に
よるスラックスの溶融温度は５７０℃好ましくは５６５
℃まで昇温してもよいので、上記共融塩が５４０℃であ
るから、３０、℃（又は２５℃）の余裕がなおあること
となる。In addition, in order to chemically activate the flux, fluoride such as aluminum fluoride (Afl, F3) or sodium fluoride (NaF) is mixed. In this case, the melting temperature of the flux by mixing is preferably 570°C. 565
Since the temperature may be raised up to .degree. C., since the temperature of the eutectic salt is 540.degree. C., there is still a margin of 30.degree. C. (or 25.degree. C.).
これは、フッ化物の種類と量の選択に幅があり、また共
融塩の混合比にも幅を持たせることができることになる
。This means that the type and amount of fluoride can be selected from a wide range, and the mixing ratio of the eutectic salt can also be varied.

%, 18-22%, 27-33%, and 1-20%.
従って、従来の填化物フラックスを用いた場合と異なっ

いために溶融スラックス中の水分の脱水作業を行なう必
要はないが、長時間の運転作業中に溶融フラックス中に
生じる微量の不純物（金属、水分、酸素等）を除去して
、より高精度のろう付けを保証する必要がある。Therefore, unlike the case of using conventional filler flux, the flux used in the method of the present invention does not have deliquescent properties, so there is no need to dehydrate the water in the molten slack, but it does require long-term operation. It is necessary to remove trace impurities (metals, moisture, oxygen, etc.) that occur in the molten flux during the soldering process to ensure higher precision brazing.
このため、本発明は直流電解法によりこれらの不純物を
容易にかつ必要に応じて除去する方法を提案するもので
ある。Therefore, the present invention proposes a method for easily removing these impurities as needed by direct current electrolysis.

(0.05 A/cm2 per unit electrode area).
