我省铜精矿的特点是硅高硫低,并含有部分氧化铜矿,加上各矿山逐步提高精矿品位,导致我厂转炉吹炼高品位冰铜,这在国内来说,目前是比较特殊的.我厂由于供矿点多,配料工作不甚完善,因此冰铜品位波动很大,在36~69%之间,一般45~55%,吹炼过程热量相应紧张,加上生产配合和技术操作等原因,多年来,各项技术经济指标都不太好,自产冷料和精炼反射炉返渣堆积如山,无法处理,成为我厂生产上的“老大难”之一.“冷料山”最多的一年,超过1万吨,全部返回电炉处
Copper concentrate in our province is characterized by high sulfur and low silicon, and contains some copper oxide, with the mine gradually improve the concentrate grade, resulting in high-grade converter converter blowing matte, which in the country, is currently compared Special.My factory because of mine for more points, the ingredients work is not perfect, so the grade of copper matte volatility, between 36 to 69%, generally 45 to 55%, the corresponding heat during the blowing process, coupled with the production of And technical operation and other reasons, over the years, the technical and economic indicators are not very good, self-produced cold material and reflactive furnace slag backfill pile, unable to handle, become my factory production “old man ” one. “Cold Mountain” up to a year, more than 10,000 tons, all returned to the furnace
