Abstract：Shandong Molong HIsmelt ironmaking process utilizes non- coking coal powder to reduce ferrous raw materials in a smelting furnace vessel to produce high- purity iron for the high- end manufacturing industries (such as nuclear power). And it is a revolutionary new technology in the field of ferrous metallurgy. Firstly, the overview of Shandong Molong HIsmelt factory and the reaction mechanism of the smelting reduction vessel were introduced. Secondly, the main production indexes of Shandong Molong HIsmelt process were analyzed and the results showed that the main production indexes of Shandong Molong HIsmelt were obviously superior to that of the Rio Tinto HIsmelt factory. And of the produced high- purity molten iron had low phosphorus content, almost did not contain Si and Mn elements and the contents of other five harmful elements were very low, which met the requirement of the high- end manufacturing industries for iron raw material. Finally, the characteristics of Shandong Molong HIsmelt production process were summarized, the adjustment of the smelting status in the furnace through the synergetic action of the three major operating systems (adjusting the injection coal capacity, adjusting the quantity of iron- containing materials injection and adjusting the rich oxygen amount in hot wind) was analyzed and the influence of hot metal temperature and coal consumption was discussed.
