Description
言い換えれば、ステンレス鋼を800℃近傍、安全をとれば800℃以上の高温で加熱して、ろう付けするときには、この窒素+COガスが還元性ガスとして、保証して使えることになる。また、800℃以下の場合には、図3に示す通り、ステンレス鋼部分に対する酸化還元平衡酸素分圧以下にならず、還元力が弱く、この窒素雰囲気のみでは不充分であるため、還元力の大きな水素ガスを併用し、ステンレス鋼の酸化還元平衡酸素分圧より低い酸素分圧下の雰囲気ガスとする。
なお、前記ろう付け加熱室のグラファイト製マッフル内の不活性ガスとしては、窒素ガスまたはアルゴンガスが使用され、前記ろう付け加熱室より前方向と後方向に設けられた室内の不活性ガスには窒素ガスを使用することが好ましい。
また、前記したろう付け加熱室より前方向と後方向に設けられた各室内の雰囲気として使用される窒素は、室温以下に保たれることが好ましい。
この連続式加熱炉1中をメッシュベルト2が循環して、被ろう付け製品である金属部品を炉内へ順次かつ連続して移送する。符号8は炉の運転操作パネルである。
加熱室3内の雰囲気:窒素+水素60容量%ガス
室4,5,6,7内の雰囲気:窒素
加熱室3内でのろう付け加熱温度:740℃
水素をその爆発限界の4容量%以上で、この実施例1では使用したが、背をなす加熱室3内の雰囲気水素ガス(ガス比重0.069:空気1)は、この背より裾状に下方に延びる室4,5,6,7内の窒素ガス(ガス比重0.977)によって加熱室内に抑止されて、炉の入口と出口の周辺の大気から完全に断絶され、爆発の危険性は終始除去された。
加熱室3内の雰囲気:窒素+COガス
室4,5,6,7内の雰囲気:窒素
加熱室3内でのろう付け加熱温度:920℃
加熱室内の雰囲気:アルゴンガス+COガス
室4,5,6,7内の雰囲気:室温以下の窒素
加熱室3内のろう付け加熱温度:1200℃
この参考例の高温下でのろう付けにおいても、ステンレス製品は美麗に光輝ろう付けされた。この参考例においても、加熱室内の雰囲気がステンレスに対して還元性であることは、図3の平衡図より明らかな通りである。

Claims (3)
- ろう付け加熱室を上方に配置し、該加熱室前後の入口と出口にはそれぞれ下方へ向かって連通して延びる前方向と後方向の室を備えた連続式加熱炉において、前記ろう付け加熱室内にはグラファイト製のマッフルを設けて、コンベヤーにて連続して搬送されてくる一部にステンレス鋼製部品を含む製品をろう付する方法であって、前記ろう付け加熱室のマッフル内のろう付け温度は800℃以下であり、またろう付け雰囲気は水素ガスを4容量%以上添加したステンレス鋼の酸化還元平衡酸素分圧より低い酸素分圧下の不活性ガス雰囲気であり、かつ前記したろう付け加熱室より前方向と後方向に設けられた室内の雰囲気は不活性ガスとすることを特徴とするステンレス鋼部分を含む製品の加熱ろう付方法。
- 前記ろう付け加熱室のグラファイト製マッフル内の不活性ガスが窒素またはアルゴンであって、前記ろう付け加熱室より前方向と後方向に設けられた室内の不活性ガスが窒素である請求項1記載のステンレス鋼部分を含む製品の加熱ろう付け方法。
- 前記ろう付け加熱室より前方向と後方向に設けられた室内の窒素が室温以下に保たれる請求項2記載のステンレス鋼部分を含む製品の加熱ろう付け方法。
