对首钢两座高炉的锌负荷和碱金属负荷进行了研究,其锌负荷分别为497、680 g/t,碱金属负荷分别3.5673、.487 kg/t,均明显高于同行业标准。锌负荷和碱金属负荷偏高已影响高炉正常生产,必须尽快对高炉洗气灰等高锌物料进行脱锌处理,严密监视高炉碱金属平衡,在必要时采取排碱的技术措施。 The zinc load and alkali load of two blast furnaces in Shougang Group were investigated. The zinc load was 497,680 g / t and the alkali load was 3.5673 and .487 kg / t, respectively, which were significantly higher than those in the same industry. High zinc load and high alkali load have affected the normal blast furnace production. High-zinc materials, such as blast ash, must be dehumidified as soon as possible. The blast furnace alkali-metal balance should be closely monitored and if necessary, technical measures taken for the discharge of alkali should be taken.
