Abstract: In order to develop the process of smelting reduction of phosphorus ore,the reduction of phosphate in molten slag was investigated in laboratory. The experiment results showed that there existed three reactions of phosphate reduction,i, e. , solid carbon,carbon in liquid iron saturated with carbon and phosphorus, and CO gas could reduce phosphate in the slag under the conditions of smelting reduction. The basic data were obtained for the research on kinetics of phosphate reduction.

摘要： 对磷酸盐熔融还原进行了实验研究.研究了固体石墨碳、Fe-P-C饱和熔体、CO气体还原熔融磷渣中磷酸盐,以及温度、渣碱度、搅拌条件等对磷酸盐还原的影响.实验结果表明,从还原反应来看,磷矿石的熔融还原是可行的.
