文摘

This paper investigated the effect of hydrogen addition on gas utilization in BF. The effect of hydrogen addition on the heat effect of reduction has been analyzed. This paper has obtained the effect of H2 addition on rate and degree of reduction. The effect of temperature on the reduction behavior of pellets has been analyzed. The optimum H2 content of gas-injection BF should be 5%–10%.
