Abstract (en)
[origin: US5264023A] The invention concerns a cored wire comprising a metal tube and a filling of magnesium or other pyrophoric metals passivated with from 0.5 to 5% by weight of organic nitrogen compounds. As the passivating agent, compounds from the series of the s-triazine and/or guanidine derivatives, preferably from 2 to 5% by weight of dicyandiamide, applied by means of an adhesion promoter, are preferred. The wires used in accordance with the invention serve to produce cast iron with spheroidal and vermicular graphite, to desulphurize pig iron melts or to produce metal alloys.
