摘　　要：转炉吹炼终点判断对整个火法冶炼过程至关重要,过吹、欠吹都会对产品质量、周期控制造成重大影响,前期的终点判断完全由炉长个人经验判断。研究开发一套铜终点在线监测系统,通过对造渣期炉内PbO和PbS强度采集和分析、造铜期内烟气中SO_2浓度采样分析、吹炼过程中熔体温度监测以及吹炼过程仿真预测,帮助炉长判断造渣期及造铜期终点,避免了转炉过吹、欠吹对生产的影响,保证生产安全,提高生产效率,初步实现了铜转炉吹炼过程智能控制。Judgment of converter blowing ending is essential for entire smelting process.Either over blowing or less blowing will have a tremendous influence on product quality and cycle control.Early judgment of end point is entirely performed based on personal experience of the furnace.By analyzing characteristic spectra of PbO and PbS in melt during slagging and SO2 concentration in flue gas of boiler during copper production,monitoring temperature of melt,and forecast by simulation of smelting,copper end point on-line monitoring system is developed to help operator to judge end point of converter blowing,ensure production safety and improve production efficiency.Intelligent control of converting process of copper converter is preliminarily realized.
