50年代末,生产固态海绵铁的直接还原法已避开了铁矿石还原的炼焦工序。80年代末,第一套Corex生产装置便把无焦炼铁变成了现实。为此,本文将着重阐述各种铁矿石还原法的目前发展水平。并根据新建厂的投资和典型消耗方面的可利用物料来估算每吨海绵铁、每吨碳化铁和每吨生铁的生产成本。

The late 1950s, the production of solid sponge iron direct reduction method has been to avoid the reduction of iron ore coking process. In the late 1980s, the first Corex production unit turned non-cokemaking into reality. To this end, this article will focus on the current level of development of various iron ore reduction method. The production costs per ton of sponge iron, tonne of iron carbide and tonne of pig iron are estimated based on the available materials for the new plant’s investment and typical consumption.
