转底炉技术及其在含铁尘泥处理中的应用

Treatment Process by Rotary Hearth Furnace and Its Application in Treatment of Iron-bearing Sludge

钢铁企业产生大量含铁尘泥,且锌、碱金属含量较高,不利于回收利用,转底炉技术有效地解决了该问题,使尘泥中的有价金属得到了很好的回收。概述了Inmetco、Fastmet、Fastmelt和Itmk3等处理含铁粉尘的转底炉工艺,并详细介绍了国内外转底炉处理含铁粉尘的应用情况,指出了转底炉技术存在的问题,展望了转底炉处理含铁尘泥的未来发展方向。

The large amount of iron-bearing sludge with high content of such elements as Zn,Na, K in steel-producing by steel enterprises was not easy to be recycled. However, the problem was solved effectively by using the treatment process by rotary hearth furnace and thus the valuable metals in the sludge can be recycled effectively. So such treatment processes for treating iron-bearing sludge by rotary hearth furnace as Inmetco, Fastmet, Fastmelt, Itmk3 were introduced.Meanwhile the applications of these processes at home and abroad were discussed in detail and the problem of the treatment process by rotary hearth furnace was proposed. At last the development trend of the treatment process by rotary hearth furnace for treating iron-bearing sludge in the future was forecasted.
