摘要
含铁尘泥是钢铁生产过程中从不同工艺流程的除尘系统中排出的含铁粉尘。这些尘泥回收后利用不当,不仅会造成环境污染,也是对含铁资源的巨大浪费。本文概述了钢铁工业含铁尘泥的综合利用现状,对瓦斯泥、转炉污泥、轧钢污泥、高锌含铁污泥、电炉粉尘等几类重点尘泥,提出了未来高附加值利用的方向。
The iron-containing dusts ＆ sludges are separated from the dedusting system of different technological processes during the production of iron and steel making.There are not only the pollution to surroundings but also the large wastes of resource containing iron unless there are properly utilized after recovery.In this article,present utilization state of dusts ＆ sludges in iron ＆ steel industry is briefly introduced,and several typical dusts ＆ sludges（e.g, blast furnace gas dust ＆ sludge,converter sludge,steel rolling sludge,electric furnace dust,zinc ＆ iron-containing sludge,etc.） are emphasized,whose high-value recovery trend are suggested.
