提出了一种难处理氧化物直接还原的方法,同时与传统处理铬矿的工艺——烧结球团法的生产周期进行了分析对比。新方法可以降低铁合金工业的环境影响,回收废弃物,拓展资源用途,提高金属收得率,尤其可以降低CO_2的排放,减少或取消使用焦炭,并且可以降低冶炼过程的电耗。
A method of direct reduction of refractory oxide was proposed. Meanwhile, the production cycle of sinter pellet was analyzed and compared with the traditional process of chrome ore. The new method can reduce the environmental impact of ferroalloy industry, recycle waste, expand resource use and increase metal yield, especially reduce CO 2 emissions, reduce or eliminate the use of coke, and can reduce power consumption in the smelting process.
