富氧顶吹炉处理氧化矿生产实践

Production practice and exploration of oxygen enriched top blown furnace for treating oxidized ore

富氧顶吹炉直接炼铅原料通常为硫化矿,氧化矿由于含S低、熔炼过程吸热,反应不均衡等给富氧顶吹熔炼工艺带来新的难题。本文介绍了云南驰宏资源综合利用有限公司从工艺过程控制及设备改进方面着手开展研究,有效地解决了生产难题,实现氧化矿的连续熔炼,处理量逐步提升,大大缓解了硫化铅精矿采购难的问题。

The raw material for direct lead smelting in oxygen enriched top blown furnace is usually sulfide ore.due to the low content of s in oxide ore,heat absorption in smelting process and unbalanced reaction,new problems are brought to the oxygen enriched top blowing smelting process.This paper introduces the smelting plant of Chihong resources comprehensive utilization Co.,Ltd.to carry out research from the aspects of process control and equipment improvement,which effectively solves the production problems,realizes the continuous smelting of oxide ore,and gradually increases the processing capacity,which greatly alleviates the problem of purchasing lead sulfide concentrate.
