炉渣中铜损的模型和控制

Modeling and control of copper loss in smelting slag

2007年和2008年,超达(Xstrata)铜业芒特(Mount)艾萨冶炼厂进行了一系列的技术改进,目的是为了解决旋转式保温炉(RHF)渣中高铜损的问题。2006年和2007年,旋转式保温炉渣中的铜损超过了3%。澳大利亚超达铜业冶炼厂将热力学模型和粘度模型应用于生产中。为了减少旋转式保温炉渣中的铜损,开发了旋转式保温炉关键绩效指标RHF KPIs。"RHF KPIs理论"已应用于芒特艾萨铜冶炼厂。旋转式保温炉渣中的铜损从2007年的3.1%降到了2009年的0.76%。2009年和2010年,旋转式保温炉渣中的平均铜损大约为0.9%。

A series of technical improvements have been implemented to address the issue of high copper losses in rotary holding furnace （RHF） slag, which were experienced at the Xstrata Copper Smelter at Mount Isa in 2007 and 2008. The copper losses in smelting slag in the RHF were more than 3% in 2006 and 2007. Thermodynamic models and viscosity models have been applied in the operation of Xstrata Copper Smelter in Australia. The theory of RHF key performanee indicators （KPIs） has also been developed to reduce the copper losses in RHF slag. The RHF KPIs Theory has been applied in Mount Isa Copper Smelter. The copper losses in RHF slag dropped from 3.1% in 2007 to 0.76% in April 2009. The average copper loss in RHF lag in 2009 and 2010 was about 0.9%.
