摘要
研究了用高硅低钼的钼精矿生产钼铁问题。二氧化硅在冶炼时造成熔点高，炉渣粘度大，铁合金沉降不完全。采用单独焙烧、半成品氧化钼搭配使用、适量添加优质氧化钼，增加Ｆｅ３Ｏ４，硅铁代替部分铝粉，适量增加硝酸钠等措施。
The method of production of molybdenum concentrate using high Si and Low Mo was researched.The melting point of silica was high when it was smelted,slag viscosity was large and sedimenation of ferroalloy wasn′t perfect.By measure of individual roasting,using semiproducts and molybdenum oxide together,adding molybdenum oxide in high quality and Fe 3O 4,using ferrosilicon taking place of aluminium powders,and using sodium nitrate etc,the products are up to the standard of GB3649 87 FeMo55A.
