有证据说明,吹炼含Cu65～70%的高品位冰铜,特别是由闪速熔炼炉或熔浴熔炼反应炉所获得的这样的冰铜的效益正显著增加。但是,要在φ3.96米×9.14米转炉、鼓风量为700～750标米3/分的条件下,实现其可能达到的满负荷生产的效益似乎还有困难。但在下述的鼓风量情况下吹炼能全面改善转炉的生产操作,能迅速确立最佳操作温度,可取得如下的结果:(1)改善造渣条件,减少四氧化三铁生成;(2)改善脱除挥发性杂质的条件;(3)风口衬里的寿命可延长;(4)增加本工厂内的二次物料处理的能力。通过使用较低富氧空气还能使生产得到进一步改善。本文探讨采用大风量(通过风口的风速为140米/秒)处理高品位冰铜的实际生产操作的技术和经济效益。
There is evidence that the benefit of blowing such high matte copper containing 65-70% Cu, especially such matte obtained from a flash smelting furnace or a melt bath smelting furnace, is significantly increased. However, it seems that it is still difficult to achieve the full-scale production efficiency that it can achieve under the condition of φ3.96m × 9.14m converter and blast volume of 700 ~ 750m3 / min. However, in the following case of blowing air blowing can fully improve the converter production operations, to quickly establish the optimal operating temperature, the following results can be obtained: (1) to improve slag conditions, reducing the formation of iron oxide; (2) Improve the conditions for the removal of volatile impurities; (3) extend the life of the tuyere lining; (4) increase the capacity of the secondary material handling in the factory. Production can be further improved by using lower oxygen-enriched air. This article explores the technical and economic benefits of actual production operations that handle high-grade matte with a large volume of wind (140 m / s through the tuyere).
