摘　　要：介绍了中铜东南铜业有限公司旋浮熔炼技术给料方式从原来“下料溜管+旋浮喷嘴”变更为“风动溜槽+旋浮喷嘴”的仿真模拟与工业试验情况,从失重计量系统、旋浮喷嘴给料形式、指标变化情况等多方面分享了旋浮熔炼给料稳定性提升的理论研究与实践经验。“风动溜槽+旋浮喷嘴”模式应用于旋浮熔炼后,取得了渣含铜降低、冰铜品位稳定性提高、烟尘率下降等效果,为熔炼生产长周期稳定运行奠定了基础。The simulation and industrial experiments related to changing the feeding method in the suspension smelting technology at China Copper Southeast Copper Co.,Ltd.,from the original“chute+rotary floating nozzle”to the“pneumatic chute+rotary floating nozzle”system were introduced.The theoretical research and practical experience in improving the feeding stability in suspension smelting were shared from weight-loss measurement system,feeding method of rotary floating nozzle,and key indicator changes.After the application of the“pneumatic chute+rotary floating nozzle”system in suspension smelting,the copper content of slag is reduced,the stability of matte grade is improved,and the dust rate is decreased,which lays a foundation for the long-term stable operation of smelting production.
