目前,世界炼铁生产的主流是高炉工艺,但该工艺需要一些原料准备设备,如焦炉、烧结设备等,而其会给环境带来很大影响。气基直接还原铁如MIDREX工艺是高炉炼铁工艺的替代方法之一,然而,该工艺受到以经济方式获得天然气的限制。在这一背景下,对可以使用更广泛的原料和燃料,且对环 At present, the mainstream of ironmaking in the world is the blast furnace process, but the process needs some raw material preparation equipment, such as coke ovens and sintering equipment, which will greatly affect the environment. Air-based direct reduced iron, such as the MIDREX process, is an alternative to blast furnace ironmaking processes, however, the process is limited to obtaining natural gas economically. In this context, it is possible to use a wider range of raw materials and fuels, and to the ring
