包头稀土精矿冶炼FeSiRE32-B合金新工艺探索

PROBE INTO NEW PROCESS OF SMELTING FeSiRE32- B ALLOY WITH BAOTOU RARE EARTH CONCENTRATE

就使用包头中品位稀土精矿为原料，采用硅热还原“二次”精炼法试制高品位不粉化稀土硅铁合金进行了实验研究。结果表明，该法冶炼 FeSiRE32- B合金具有一定的可行性。

Thc test study was conducted on smelting un- powdered high grade RE ferroalloy with secondary refining of silicothermic reduction.The result showed that smelting FeSiRE32- B alloy with this method was feasible.
