摘要 |
Process for producing vermicular cast iron comprising: (i) forming a near eutectic melt having a sulfur content preferably less than about 0.025% by weight; (ii) admixing at least one rare earth-containing additive with said melt to form stable rare earth oxysulfides thereby reducing and maintaining the Henrian sulfur activity in the melt at between about 0.004 and 0.035; and (iii) thereafter, allowing said melt to solidify. |
