以铁精矿粉为供铁剂，使用工业废渣氨浸渣、钼酸钙进行了直接还原冶炼钼铁实验研究，分析了氨浸渣及钼酸钙加入量对碱度、冶炼周期、金属回收率、冶炼温度的影响。结果表明，钼酸钙含量增加，碱度提高，金属回收率上升，冶炼周期随之降低；氨浸渣加入量增加，冶炼温度下降。在1500℃，CaMoO4／氨浸渣质量比1．5，碱度1．2时，冶炼效果较好。

With iron concentrate powder as iron?addition agent, the industrial residue including ammonia leach residue and calcium?molybdate were used in the experiment for preparing ferromolybdenum by direct reduction process. The effect of addition of ammonia leach residue and calcium?molybdate on alkalinity, smelting time, metal recovery rate, and smelting temperature was investigated in the tests. It is found that increasing the addition of calcium molybdate can lead to the alkalinity increased and metal recovery rate improved, thus smelting time shortened, while increasing the amount of ammonia leach residue can result in a drop in the smelting temperature. It can be seen that a better result was obtained at the smelting temperature of 1 500 ℃, with alkalinity of 1.2 and the mass ratio of CaMoO4 to ammonia leach residue at 1.5.
