Abstract

　Ｃｒを５％以上含有する高合金鋼からなる被圧延材の延伸圧延後におけるマンドレルバの引き抜き不良を効果的に抑制しながら、継目無鋼管を製造する。 　マンドレルバ２の軸方向への速度を一定に保つリテインドマンドレルミル１を用い、マンドレルバ２の移動速度Ｖｂを制御することにより、マンドレルバ２の移動速度Ｖｂ、リテインドマンドレルミル１の入側における被圧延材３の速度Ｖｉ、及びリテインドマンドレルミル１の出側における被圧延材３の速度Ｖｅが、０．１５≦Ｖｂ／｛（Ｖｉ十Ｖｅ）／２｝≦０．７０の関係を満足するようにして、被圧延材３に延伸圧延を行うことによって、５％以上のＣｒを含有する高合金鋼からなる継目無鋼管を製造する。
