Description
ビレットは、加熱炉1で加熱され、穿孔機、例えば傾斜ロール圧延機(ピアサー)2で穿孔圧延されてホローシェルとなる。穿孔圧延工程は、マンネスマン方式による穿孔圧延方法をはじめとして、その他の各種の穿孔方法を適用できる。穿孔圧延条件には特に制約はない。ビレットはインゴットから分塊圧延を経て製造されたものでもよく、また、例えば円形断面の鋳型を用いて連続鋳造された、いわゆる丸ビレットでもよい。
この温度は、600℃から800℃未満の範囲としなければならない。その理由は次のとおりである。まず、定径圧延終了時の継目無管の温度が600℃よりも低温になるような条件では、定径圧延設備に過大な負荷がかかって、定径圧延工程が困難となる。
定径圧延後、継目無管は再加熱炉5で再加熱される。継目無管の温度は、定径圧延工程終了後から再加熱に移るまでの間に低下するが、その温度は400℃から800℃未満までの範囲となるようにする。言い換えれば、継目無管の温度が400℃から800℃未満の範囲にある間に、再加熱炉に装入しなければならない。
再加熱炉から取り出した継目無管は再加熱処理でAc3変態点以上になっているから、これを焼入れ装置6(例えば水冷装置)に直ちに投入して焼入れを施す。なお、厚肉の継目無管を均一に急冷するためには、継目無管の内外面を同時に冷却することが可能な急冷装置を使用するのが望ましい。
本発明方法で製造される継目無管の化学組成には特別な制約はない。一般に油井管やラインパイプとして用いられるあらゆる鋼種が使用できる。

Claims (1)
- 穿孔圧延工程、延伸圧延工程、定径圧延工程、再加熱工程、焼入れ工程および焼戻し工程を備え、継目無管の温度が600℃以上800℃未満となる条件で前記定径圧延工程を終了させ、前記再加熱工程において400℃以上の継目無管を再加熱炉に装入し、Ac3変態点以上1000℃以下の温度に再加熱することを特徴とする継目無管の製造方法。
