韶钢高炉入炉原料中有害元素含量偏高,主要是受碱金属和铅锌的长期影响。6号高炉在开炉投产不到2年时间就出现炉体上涨的现象。对此,采取定期排碱、炉外排铅等一系列措施以减轻有害金属的危害。从后期实施的效果来看,6号高炉炉体上涨的趋势得到了控制,高炉得以安全正常生产。 Shaoguan blast furnace into the furnace of raw materials harmful elements content is high, mainly due to the long-term effects of alkali metals and lead and zinc. No.6 blast furnace put into operation in less than two years appeared furnace body up phenomenon. In this regard, to take a regular row of alkali, lead efflux and a series of measures to reduce the hazards of harmful metals. From the late implementation of the effect point of view, No. 6 blast furnace furnace has been the trend of rising control, the blast furnace to safe and normal production.
