摘　　要：研究了竖炉法冶炼铬镍生铁的工艺,分析了铬、镍生铁中磷的来源,并结合理论计算和实际生产,得出以下结论:原料中的磷绝大部分还原进入生铁,因而可通过控制原料中的磷含量来控制最终生铁中的磷含量,并提出了降低磷铬镍生铁中磷含量的可行性措施。In this paper, the processing of Iron making beared with Cr -Ni has been studied, the origin of phosphorus has been analysed, combined with theoretical calculation and real practice, it can be concluded that the majority of phosphorus in the raw material is reduced into iron. Therefore, phosphorus of iron can be controlled by selecting raw material of low phosphorus. Feasible technological measures are put forward to reduce final phosphorus of Cr-Ni iron.

关 键 词：富氧竖炉 低磷生铁 还原气氛
