摘要
对“二步法”冶炼铌铁工艺预还原的除磷分铁影响因素进行了研究，优化了得到（Ｎｂ／Ｆｅ）＞１．０、（Ｎｂ／Ｐ）＞１０的富铌渣技术条件，并对富铌渣和副产品半钢结构进行了分析。
The influence of technical conditions on dephosphorization & deferrization during prereduction in the 'Two step' metallurgy of Nb and Fe has been studied. Optimized technical conditions for Nb/Fe>1. 0 Nb/P>10 Nb-rich slags are obtained. Analysis is made on the Nb-rich slags nad semi-steel structures of by-products.
