The continuous copper smelting technology has developed rapidly in recent years, among which the double-side blowing smelting multi-lance top blowing continuous converting technology has gradually become one of the mainstream process flows adopted in new copper smelting projects. The article systematically reviews the latest development and application status of the process, comprehensively analyzes the characteristics and advantages of the technology, and elaborates in detail on the design innovation concept and production technology indicators of the process. Reduction of adhesion and maintenance of the side blowing furnace waste heat boiler flue, smoke and dust injection, multi-mode operation of multi-lance top blowing furnace, and APC intelligent control technology have been successfully applied in the Houma North Copper Project. After being put into operation, it has been continuously and stably running for more than a year, with a system operating rate of over 98.5%. The annual output has increased from 80000 tons to 200000 tons, and the energy consumption per unit product indicator has been reduced by 50%. The application practice of this project has solved the previous production problems of the double-side blowing smelting multi-lance top blowing continuous converting process, and further promoted and improved the safety, automation level, production indicators and environmental protection indicators of the process.
