大冶有色冶炼厂共有 4台转炉 ,担负着每年十几万吨的粗铜吹炼任务。根据近年来的发展需要 ,结合转炉的实际吹炼情况 ,参考国内同行的经验 ,决定对 1996年建成的 1# 转炉进行改造 ,增加其单炉容量 ,进一步提高粗铜吹炼能力。在转炉两边共计加长 75 0mm ,加大炉口 ,并增加 4个风 Daye Nonferrous Smeltery a total of 4 converter, responsible for more than 100,000 tons of blister annually blowing mission. According to the development needs in recent years, combined with the actual blowing situation of the converter, with reference to the experience of domestic counterparts, it was decided to transform the No. 1 converter built in 1996 to increase its single-furnace capacity and further improve the blowing capacity of blister copper. On both sides of the converter total lengthened 75 0mm, increase the furnace mouth, and increase the 4 wind
