Method of producing ductile iron |
摘要 |
Process for producing ductile iron by treating liquid iron with an initializer which is a ferrosilicon alloy comprising an effective amount of barium sufficient to inactivate the oxygen activity of the liquid iron. This is followed at a predetermined time thereafter by treating the liquid iron with a magnesium containing nodularizer, followed by treating the liquid iron with a eutectic graphite nucleation-inducing inoculant, and casting the iron. |
