一、试验目的日本学术界和产业界正合作致力于“喷射炼锌方面”实际应用的研究。其目的在于开发一种节能型的且可利用廉价煤进行熔融还原熔炼的方法以取代石油和降低锌的成本。试验内容是研制向熔融渣喷射富氧空气、还原剂、锌精矿后可以高效率地产生锌蒸气的熔炼炉以及使锌蒸气冷凝的冷凝器。 First, the purpose of the experiment Japanese academia and industry are working together to “spray zinc” aspects of the practical application of research. Its purpose is to develop an energy-saving method that can be used for smelting reduction smelting with cheap coal to replace petroleum and reduce the cost of zinc. The test was to develop a smelting furnace for producing zinc vapor with high efficiency by spraying oxygen-enriched air, a reducing agent and zinc concentrate to molten slag, and a condenser for condensing zinc vapor.
