An object of the research is to know if it is possible that phosphorus contained in iron ore can be removed before charging blast furnace.Artificial iron ore containing phosphorus oxide is reduced under gaseous atmospheres with various oxygen potentia1s.It is revealed that the phosphorus can be removed from the iron ore when the experiments carried out under an atmosphere with the oxygen potential at which metallic iron can't be produced from iron oxide.It is estimated that the phosphorus is removed as gaseous phosphorus.

研究的目的是了解铁矿石中含磷是否有可能在高炉装料前脱除。含氧化磷的人工铁矿在不同氧势的气态环境下进行还原。结果表明，在氧化铁不能产生金属铁的氧势气氛下，铁矿中的磷是可以脱除的。据估计，磷以气态磷的形式被去除。
