摘要
对目前国外转底炉炼铁发展和工艺进行了综合阐述,主要包含INMETCO和Fastmet工艺,从Fastmelt的发展,到生产规模最大的美国动力钢的IDP,以及日本神户制钢、美国Midrex公司联合开发的转底炉生产铁块(Nuggets)的所谓Itmk-3(第三代炼铁法)等多种工艺。同时,对中国引进和发展这项技术阐述了其必要性和可行性。
The ironmaking technology of rotary hearth furnace and its development abroad are introduced and discussed in this paper comprehensively, including INMETCO and the development from Fastmet to Fastmelt, IDP （developed by US Steel Dynamic Inc）, as well as polytechnics of COMET, REDSMELT and DryIron, and also the so-called Itmk-3 （third generation ironmaking processes）, which is co-developed by Kobe Steel of Japan and some of US companies and the Nuggests is produced in rotary hearth furnace. The possibility and the necessity for China to develop such new technology are also involved.
