超细铁粉的连续制备

Continuous Production of Ultrafine Iron Powder

摘要: 研究了用直流电弧等离子体法连续制备超细铁粉及提高产率的方法。结果表明,阴极用斜电极比用竖直电极产率提高50%左右,用钨铁混合物做原料比用纯铁产率提高一倍左右。

Abstract: The DC electric arc plasma method of increasing generation rate of ultrafine iron powder is studied.The results show that the generation rate of ultrafine iron powder is increased about 50% with a inclined electrode and it is increased one time when the pure iron was substituted with a mixture of tungsten and iron.
