南京特种合金厂采用电硅热法成功地研制出:含Zr35～40％、Si47～52％、Ti<1.5％、C<0.15％、P<0.15％的新型铁合金—硅锆铁合金。为铁合金产品增添了一个新的品种,且成本较低。锆是一种非常好的炼钢脱氧剂,其脱氧 Nanjing Special Alloy Plant successfully developed a new type of ferro-silicon-zirconium-iron alloy with 35-40% Si, Si47-52%, Ti <1.5%, C <0.15% and P <0.15% by electrical silicon thermal method. A new variety has been added to ferroalloy products at a lower cost. Zirconium is a very good steel-making deoxidizer, which deoxidizes
