为了研究装料方式对高炉间接还原区还原效率的影响,通过模拟不同装料方式下高炉炉料组成、温度场和气体成分条件,研究了装料方式对含铁炉料静态还原的影响规律。结果表明,8号高炉现有的3种装料方式中,通过将大小烧分级入炉,在不改变原料条件下,可以改善块状带炉料的透气性,增加含铁炉料的还原度和还原效率。 In order to study the effect of charging mode on reduction efficiency of indirect reduction zone of blast furnace, the effect of charging mode on the static reduction of iron-bearing charge was studied by simulating blast furnace charge composition, temperature field and gas composition under different loading modes. The results show that among the three existing charging modes of No. 8 blast furnace, the grading of small and large burners can be put into the furnace to improve the gas permeability of the block-shaped belt charge and to reduce the reduction degree and reduction of the iron-bearing charge without changing the raw materials effectiveness.
