中文摘要：
采用自主设计的间歇振动式斜直管移动床反应器对不锈钢冶炼粉尘进行预还原,以铁浴终还原炉产生并重整的含H2和CO的混合气体作为还原气,探索中低温条件下各因素对不锈钢粉尘预还原反应的影响.结果表明,在气固比0.85L/g、还原气体成分CO0～40%（φ）、振动间歇比1：2的优化条件下,预还原率较高,最高可达73.6%.
英文摘要：
Pre-reduction of fine dust from stainless steel making was studied in a new designed moving bed reactor with inclined tube and intermittent vibrators. In experiments,mixed gas of H2 and CO was used to simulate the exhaust gas from the end reforming,for the purpose to examine the influences of different factors on the process of pre-reduction of fine dust from stainless steel making. The results show that gas-solid ratio 0.85 L/g,component of reducing gas CO 0～40%（φ）,and intermittent-vibration ratio 1：2 were the optimal conditions,and the maximal reduction rate of 73.6% was reached.
