我厂用反射炉炼锡已有近三十年的历史。生产实践表明,反射炉炼锡存在着一系列问题,尤其是近年来,由于矿山地质条件发生很大变化,难选矿物日益增多,开采品位越来越低,锡精矿产量逐年减少,精矿品位逐年下降,杂质不断上升,西湾煤质不合冶金要求,反射炉炼锡存在的问题更加突出。例如,熔炼时间长,燃料消耗多(不包括还原剂用煤),为锡精矿重量的60%,连煤中
I plant with reflex furnace tin has been nearly three decades of history. Production practice shows that there are a series of problems in the refiner smelting of tin, especially in recent years, due to great changes in the geological conditions of mines, increasing the number of refractory minerals, mining lower and lower grade, tin concentrate production decreased year by year, concentrate Grade decline year after year, impurities continue to rise, the quality of the West Bay metallurgical metallurgical requirements, Refining Furnace tin problems are more prominent. For example, melting a long time, fuel consumption (excluding reducing agent with coal), 60% of the weight of tin concentrate, with coal
