由于全球焦煤资源日趋匮乏,同时,对环境要求日益增高,因而对不需要设置烧结(或球团)和焦化设施的一些非高炉炼铁法得到钢铁产业普遍高度重视,其技术和装备不断有新的进展,现简述如下:一、Finex工艺Finex工艺的特点是不用焦煤直接以铁矿粉为原料,将铁矿粉经多级流化床进行还原,将从流化床出来 Due to the scarcity of global coking coal resources and the increasing demands on the environment, some non-blast furnace ironmaking methods that do not need to set up sintering (or pellet) and coking facilities are generally highly regarded by the steel industry, and their technologies and equipment are continuously updated The progress is summarized as follows: First, Finex process Finex process is characterized by coking coal directly to the iron ore powder as raw material, the iron ore by multi-stage fluidized bed reduction, will come out from the fluidized bed
