The present invention relates to a process for the production of ductile iron comprising the sequential steps of:- (i) treating liquid iron with an initialiser comprising an effective amount of a group Ha metal other than Mg, (ii) at a predetermined time after step (i), treating the liquid iron with a magnesium containing nodulariser, (iii) treating the liquid iron with a eutectic graphite nucleation-inducing inoculant, and (iv) casting the iron. The invention allows for the variability of oxygen content in the base iron to be processed such that the mechanical properties of components cast from the processed iron are independent of the original oxygen content of the base iron.
L'invention porte sur un procédé de production de fer ductile comprenant les étapes suivantes: (i) traitement du fer liquide par un amorceur comprenant une quantité efficace d'un métal du groupe Ha autre que le Mg, (ii) un certain temps après l'étape (i), traitement du fer liquide avec un noduliseur contenant du Mg, (iii) traitement du fer liquide avec un inoculant inducteur de nucléation de graphite eutectique, et (iv) coulée du fer. L'invention permet de faire varier la teneur en Ox du fer de base à traiter pour que celle des composés moulés à partir du fer traité soient indépendante du contenu original en Ox du fer de base.
