The influence of different H2 content on reduction process of burden in blast furnace was investigated.The chemical compositions of the reduced burden were determined.The results show that the Fe aggregates obviously with the increasing of the H2 content in the reducing gas.The weight loss rate,the reduction rate and the metallization rate of the burden increase with the increasing of the H2 content.Because the H2 content was increased the indirect reduction was improved,so the degree of direct reduction was decreased effectively.Although the metallization rate also increases with the H2 content,much higher H2 content will cause the reduction of non-ferrous metal and thus higher energy consumption.So H2 content in the reducing gas should be controlled within a proper range of~15%.
