Description
C:0.2〜0.7%。Cは鋼管の熱処理による強度を確保するために重要な元素であり、0.2%以上含有させる。ただし多くなりすぎると、効果が飽和するばかりでなく非金属介在物の生成形態が変化したり鋼の靱性が劣化したりするので、0.7%までとする。
Caの添加量と、その歩留りおよび上記の介在物中のCa/Al比やCa/Ti比の最適範囲実現との関係を種々調査した結果、次のような方法を採用すればよいことがわかった。
Ca添加比=[Ca添加量(kg/ton)/40]/
[Al(%)/27+Ti(%)/48] ・・・・・・(1)
ここで、Al(%)およびTi(%)はいずれも溶鋼中の質量%である。(1)式で示される添加比が1.6未満であっても3.2を超えても、鋼中に窒化物系の介在物が増加する傾向がある。
