摘　　要：黑龙江紫金铜业有限公司15万吨铜冶炼项目熔炼段采用侧吹熔炼-底吹吹炼-阳极精炼生产工艺,一次性打通并实现全热态底吹连续炼铜工艺路线,目前,工艺运行稳定。本文将简述自建厂至今底吹吹炼炉相关改进实践,包括:入炉物料加料方式、吹炼热平衡控制、还原手段优化、重点区域防护及数模开发运用等方面;以及渣型改进、烟道结焦控制等后续的改进计划,对底吹连续吹炼的推广应用具有可借鉴意义。The Smelter of 150000 ton copper smelting project of Heilongjiang Zijin Copper Co., Ltd. adopts the production process of side blowing smelting, bottom blowing smelting and anode refining to open up the full hot bottom blowing continuous copper smelting process at one time. At present, the process operation is stable. This paper will briefly describe the improvement practice of blowing furnace since the establishment of the plant, including: feeding mode of materials into the furnace, control of blowing heat balance, optimization of reduction means, protection of key areas,development and application of digital simulation, etc;And the subsequent improvement plans such as slag improvement and flue coking control,which can reference for the popularization and application of bottom continuous blowing process.
