我们用5吨转炉吹炼第十四冶炼厂产出的高品位铜冰铜,冰铜的化学成分(%)一般为:Cu57～62,Fe13～14,S 20～22,并合有部分铜铁合金。以前认为,用小转炉吹炼含铜高达57～62%的冰铜,若不补加热源,是很难产出粗铜的。近年来,经过我们的生产实践,基本上解决了小转炉吹炼高品位冰铜的技术问题,同时获得了良好的技术经济指标:粗铜平均含铜99～99.2%,转炉渣含铜2～3.5%,直接回收
We use a 5-ton converter blowing fourteenth smelter output of high-grade copper matte, matte chemical composition (%) are generally: Cu57 ~ 62, Fe13 ~ 14, S 20 ~ 22, combined with part of the copper ferroalloy. It used to be assumed that it is very difficult to produce blister copper without using a heat source by blowing a matte copper containing up to 57 to 62% copper with a small converter. In recent years, after our production practice, basically solved the technical problem of high-grade baking copper in the converter and obtained good technical and economic indexes: the average copper content of the blister copper is 99-99.2%, the converter slag contains 2-2% 3.5%, direct recovery
