摘　　要：针对印度某铜冶炼项目高硫铜精矿(S质量分数33%~35%)的处理需求,结合闪速熔炼炉的设计与生产经验,系统分析了高硫铜精矿对熔炼过程热负荷及炉体寿命的影响。基于工艺计算与结构优化,提出了大型闪速熔炼炉关键部件(精矿喷嘴、反应塔、沉淀池、上升烟道)的创新设计方案,包括精矿喷嘴的“风内料外”供料模式、反应塔E形水套分层冷却结构、沉淀池侧墙水套布局优化及方形上升烟道的烧嘴配置。通过工程实践验证,该设计有效降低了高硫铜精矿带来的热负荷冲击,提升了炉体运行稳定性。In response to the demand of processing copper concentrate with high sulfur conent(S mass fraction of 33%~35%)in a copper smelting project in India,the influence of copper concentrate with high sulfur content on the heat load of smelting and furnace service life is systematically analyzed in combination with design and production experience of flash smelting furnace.Some innovative design solutions for key components of the large-scale flash smelting furnace(concentrate burner,reaction shaft,settler and uptake shaft)are developed by means of process calculations and structural optimization,including the“air blown-in and feed-out”charging by the concentrate burner,layered cooling structure of the reaction shaft’s E-type water jacket,optimized layout of the water jacket on the settler’s side wall,and the configuration of burner on the square-shaped uptake shaft.This design effectively reduces the thermal load impact caused by copper concentrate with high sulfur content and improves the stability of furnace operation through engineering practice verification.
