铬铁合金电炉烟尘的性质及形成机理研究

Properties and Formation Mechanism of Ferrochrome Electric Furnace Dust

通过对铬铁合金烟尘的微观结构、化学成分和物相组成的分析,发现铬铁合金烟尘主要是由小颗粒炉料直接卷入、电极孔飞溅、蒸发以及尾气管中化学反应产物组成。

The formation mechanism of the ferrochrome plant dust is postulated based on the microstructure, chemical and phase analyses. It is found that the ferrochrome dust is formed through direct entrainment of the charge, the particles splashed from the electrode hole, vaporization, and the reaction products in the off-gas duct.
