摘要

本文介绍了梅德诺戈尔斯克铜硫厂富氧鼓风冶炼含铜炉料的实践。鼓风富氧度由30%提高到36%，生产效率提高20.1%。磨砂中铜含量为33.0 ~ 35.3%，废渣中铜含量为- 0.5%。我们提供了熔炼的质量和热平衡。论证了鼓风富氧程度对鼓风冶炼生产率、固体燃料消耗量、冶炼产品含量和数量的影响。关键词:鼓风冶炼，鼓风，富氧，富集程度，炉容量，冶炼比率，冰砂，无烟煤

Using of Enriched Air Blast While Operation of Shaft Furnaces at LLC “Mednogorsk Copper-Sulfur Plant”

In this article we consider the practices of blast smelting of copper-bearing charge with oxygen enriched air blast at Mednogorsk Copper-Sulfur Plant. The degree of air blast enrichment with oxygen has been increased from 30% to 36%, and productivity has raised by 20.1%. The copper content in matte has made up 33.0-35.3%, in dump slag – to 0.5% Cu. We have provided the mass and heat balances of the smelting. We have demonstrated the influence of air blast oxygen enrichment degree on productivity of blast smelting, solid fuel consumption, contents and quantity of smelting products. Keywords: blast smelting, air blast, oxygen enriched, enrichment degree, furnace capacity, specific smelting rate, matte, anthracite
