摘要

测定了济钢炼铁厂5号1 080m

高炉入炉原燃料及产出项的锌含量

并结合高炉实际生产数据进行了锌平衡分布计算。结果表明

5号高炉锌负荷为625g/t

入炉原燃料中

以烧结矿带入的锌最多

可以达到72.22%;其次是球团矿

可以达到24.13%;支出项中

由瓦斯灰带走的锌量最多

占总支出量的96.14%。提出入炉原燃料的选用、高炉操作制度以及含铁尘泥脱锌等相应的控制措施。

Abstract

Zinc content in charging and output items for 1 080 m

No5 blast furnace at Ironmaking Plant

Jiyuan Steel has been analyzed

and combined with real production data of furnace the calculation on equilibrium distribution of zinc is carried out. Results show that zinc load of No5 blast furnace is 625 g/t

in furnace charging

most zinc load is from sinter ore its percentage is up to 72. 22%

next zinc load is from pellet ore it can reach to 24. 13% ； in output items the most amount of zinc is in gas ash which makes up 96. 14% of the total output value. The corresponding measures to control zinc including selecting of charging

optimizing blast furnace operation scheduling and dust de-zincing etc. are presented.
