Ferroelectric - alloy for the treatment of inoculation of cast irons forming

摘要

The present invention relates to a ferromagnetic - alloy for the treatment of inoculation of cast irons forming to be used as coulee, as well as a process for treating the liquid cast iron with this ferroelectric - alloy. / p & & p & this ferroelectric - alloy is characterizes in that it comprises of 0,005 a 3 by weight of at least one metal of group of the rare earths and of 0,005 a 3 by weight of at least one element taken from the group including bismuth, lead and antimony, the balance being essentially the silicon and iron normally present in the ferroelectric - alloys used for the inoculation of cast irons.
