- るつぼ底が上下方向に移動自在に形成された水冷銅製るつぼの内部に上方より装入した溶解原料を、その水冷銅製るつぼの周囲を取り巻く高周波コイルによる誘導加熱で溶解して溶湯プールとし、前記るつぼ底を下方に移動させることにより、そのるつぼ底上の前記溶湯プールを前記高周波コイルによる誘導加熱領域外に引き抜いて凝固させて、活性高融点金属含有合金の鋳塊を製造する長尺鋳塊の溶解製造方法であって、
所定の合金組成に配合した塊状、粒状、粉状のうち、少なくとも1種類の形態の溶解原料を、第1の水冷銅製るつぼ内に装入して、誘導加熱で溶解して溶湯プールを形成させた後、その溶湯プールの下部を高周波コイルによる誘導加熱領域外に引き抜いて凝固させた状態で、るつぼ底の下方への移動を停止し、更に溶解原料を前記第1の水冷銅製るつぼ内へ装入して溶湯プール内で溶解させた後、次の引き抜きを行って溶湯プールを凝固させるという工程を複数回繰り返す1番目の溶製操作と、
前記1番目の溶製操作で得られた長尺の鋳塊を上下反転した状態で、前記第1の水冷銅製るつぼより内径が大きい第2の水冷銅製るつぼ内に装入して、下部から順次溶解させ、るつぼ底を下方に移動させることにより、そのるつぼ底上に形成された溶湯プールを高周波コイルによる誘導加熱領域外に引き抜いて下部から順次凝固させる2番目の溶製操作を実施することで、
引抜方向の長さが直径に対して1.5倍以上の活性高融点金属含有合金の鋳塊を製造することを特徴とする長尺鋳塊の溶解製造方法。 - 請求項1記載の2番目の溶製操作で得られた長尺の鋳塊を用いて、2番目の溶製操作と同様の3番目の溶解操作を実施するか、或いはその3番目溶解操作を4番目以降の溶解操作として繰返し実施することで、引抜方向の長さが直径に対して1.5倍以上の活性高融点金属含有合金の鋳塊を製造することを特徴とする長尺鋳塊の溶解製造方法。
