矿热炉生产超低碳硅铁合金工艺技术的研究与应用

摘要

Describes the oxygen refining and heat down slag washing two kinds decarbonization drop combined with alumi-num technology is very good, and the use of oxygen and air mixing bottom blowing way of ultra low carbon ferrosilicon smel-ting technology, the technology in the foundation to meet production requirements, the use of natural resources is very good, the production cost is reduced.The technology of 25000KVA and below the ore heat furnace production of ultra low carbon ferrosilicon with good technical guidance and promotion significance.%论述了将吹氧精炼与热冲倒包渣洗两种脱碳降铝技术很好的结合，且采用氧气与空气混合底吹的方式来冶炼超低碳硅铁的技术，该技术在满足生产需求的基础上，很好的利用自然资源，降低了生产成本。此技术对25000 kVA及以下的矿热炉生产超低碳硅铁具有很好的技术指导性和推广意义。
