模拟高炉喷吹含氢煤气条件下炉料的变化过程，结果表明，炉料的低温还原粉化率随氢含量增加而增加。随着温度的升高炉料的低温还原粉化率降低。氢含量升高有利于铁氧化物的还原、CO的析碳，温度为900 ℃时氢对还原矿的碳含量无影响。氢含量升高，焦炭的反应后强度大幅度降低。
Reduction and transformation of solid charge in blast furnace with gas injection was studied by simulation.The results are: When the H2 content in mixed gas increases, the RDI of solid charge increases;the RDI of solid charge decreases with the increase of reaction temperature;high H2 content is advantageous for reduction of ferrous oxides and CO decomposition; H2 content has no influence on carbon content of reduced ore at 900 ℃;the strength of coke after reaction decreases sharply with the H2 content in mixed gas.
