| Abstract: |
| 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. |
