我厂炼铜鼓风炉的原料特点是,含铜较低,而含锌、铅高。由于大量的硫化锌和氧化锌相应进入冰铜和炉渣,提高了冰铜和炉渣的熔点,致使咽喉溜经常堵塞,不断造成结炉和前床冻结事故,炉龄短,消耗高,铜回收率低,大量硫、锌、铅分别进入烟尘、 Raw materials of our copper blast furnace is characterized by low copper content and high zinc and lead content. Due to a large amount of zinc sulfide and zinc oxide into the matte and slag, increased the melting point of matte and slag, resulting in throat slip often blocked, and continue to cause the freezing furnace knot and bed accident, furnace short, high consumption, copper recovery Low, a large number of sulfur, zinc, lead, respectively, into the smoke and dust,
