Title (EN) STEEL WIRE MATERIAL AND METHOD FOR PRODUCING SAME
(FR) MATÉRIAU DE FIL-MACHINE ET PROCÉDÉ POUR SA PRODUCTION
(JA) 鋼線材及びその製造方法
Abstract: front page image
(EN)The steel wire material of the present invention contains 0.05 to 1.2% of C (mass%; same for the chemical components hereafter), 0.01 to 0.5% of Si, 0.1 to 1.5% of Mn, 0.02% or less (but not 0%) of P, 0.02% or less (but not 0%) of S, and 0.005% or less (but not 0%) of N, with the balance being iron and inevitable impurities. The wire material has a scale layer that is no thicker than 7.0 µm or less. The scale layer has an FeO percentage of 30 to 80 vol% and an Fe2SiO4 percentage of less than 0.1 vol%. The scale layer that is formed will not peel when cooled after hot rolling or during storage and transport, but will easily peel during mechanical descaling.
(FR)La présente invention concerne un matériau de fil-machine contenant 0,05 à 1,2% de C (% en masse ; idem pour les composants chimiques ci-après), 0,01 à 0,5% de Si, 0,1 à 1,5% de Mn, 0,02% ou moins (mais pas 0%) de P, 0,02% ou moins (mais pas 0%) de S et 0,005% ou moins (mais pas 0%) de N, le reste étant constitué de fer et d'impuretés inévitables. Le matériau de fil présente une couche de calamine qui n'est pas plus épaisse que 7,0 µm ou moins. La couche de calamine présente un pourcentage en FeO de 30 à 80% en volume et un pourcentage en Fe2SiO4 inférieur à 0,1% en volume. La couche de calamine qui est formée ne s'exfoliera pas quand elle sera refroidie après un laminage à chaud ou pendant l'entreposage et le transport, mais s'exfoliera facilement pendant le DM.
(JA) 本発明の鋼線材は、C:0.05~1.2%(質量%の意味。以下、化学成分について同じ。)、Si:0.01~0.5%、Mn:0.1~1.5%、P:0.02%以下(0%を含まない)、S:0.02%以下(0%を含まない)、N:0.005%以下(0%を含まない)を含有し、残部が鉄及び不可避不純物である鋼線材であって、厚さ7.0μm以下のスケールを有し、且つ、該スケール中のFeO比率が30~80体積%であり、FeSiO比率が0.1体積%未満であり、熱延後の冷却中や、保管・搬送時には剥離せず、MDの際に容易に剥離するスケールが形成される。
