(FR) ALLIAGE DE FERROSILICIUM VANADIUM ET/OU NIOBIUM, PRODUCTION D'UN ALLIAGE DE FERROSILICIUM VANADIUM ET/OU NIOBIUM ET SON UTILISATION
Abstract
(EN) The invention relates to a ferrosilicon vanadium and/or niobium (FeSi V and/or Nb) alloy comprising 15 - 80 wt % Si; 0.5 - 40 wt % V and/or Nb; up to 10 wt % Mo; up to 5 wt % Cr; up to 3 wt % Cu; up to 3 wt % Ni; up to 20 wt % Mg; 0.01 to 7 wt % Al; up to 13 wt% Ba; 0.01 to 7 wt % Ca; up to 13 wt % Mn; up to 8 wt % Zr; up to 12 wt % La and/or Ce and/or misch metal; up to 5 wt % Sr; up to 3 wt % Bi; up to 3 wt % Sb; up to 1.5 wt % Ti; balance Fe and incidental impurities. The invention also relates to a method for the production of a FeSi V and/or Nb alloy and the use thereof in cast iron.
(FR) L'invention concerne un alliage de ferrosilicium vanadium et/ou niobium (FeSi V et/ou Nb) comprenant entre 15 et 80 % en poids de Si ; entre 0,5 et 40 % en poids de V et/ou de Nb ; jusqu'à 10 % en poids de Mo ; jusqu'à 5 % en poids de Cr ; jusqu'à 3 % en poids de Cu ; jusqu'à 3 % en poids de Ni ; jusqu'à 20 % en poids de Mg ; entre 0,01 et 7 % en poids d'Al ; jusqu'à 13 % en poids de Ba ; entre 0,01 et 7 % en poids de Ca ; jusqu'à 13 % en poids de Mn ; jusqu'à 8 % en poids de Zr ; jusqu'à 12 % en poids de La et/ou de Ce et/ou de mischmétal ; jusqu'à 5 % en poids de Sr ; jusqu'à 3 % en poids de Bi ; jusqu'à 3 % en poids de Sb ; jusqu'à 1,5 % en poids de Ti ; le reste étant du Fe et des impuretés inévitables. L'invention concerne également un procédé de production d'un alliage de FeSi V et/ou Nb et son utilisation en fonte.
