【摘要】 通过理论分析,得出竖炉还原过程中硫平衡关系,并讨论了还原气氢碳比及用量、还原气中 H₂S 含量、还原温度以及球团矿硫含量等对硫在竖炉中分配的影响。结果表明:在竖炉还原条件下,提高还原气的氢碳比有利于竖炉球团矿脱硫,而增加还原气用量、提高还原气中 H₂S 含量则对脱硫不利;为了达到更好的脱硫效果,还原温度应控制在915℃以上。更多还原

【Abstract】 The sulphur balance during the deoxidize process in shaft furnace was given through analysis, and the influences of H₂/CO in gas, H₂S consistency in gas, reaction temperature, S content of the ore were also discussed. The results indicate that, with the increase of H₂/CO, the sulphur in DRI decrease on the condition of shaft furnace. While, increasing the gas volume, H₂S consistency and S content of the ore gets the opposite result. To obtain lower S content DRI, the reaction temperature should be above 915℃.更多还原
