【摘要】 温度稳定的控制在1400℃左右;计算出氢气还原速率常数在1400℃下为0.93～1.03 g-Fe/cm~2·min,跟固体碳比较氢气还原速率快;避免过泡沫渣形成,原料应采用预还原矿。通过进行底吹氢熔融还原试验研究,对了解底吹氢情况下的安全性以及工艺操作参数是很有帮助的,为今后大型的工艺化实验提供经验和理论计算依据。本文重点介绍氢冶金技术的试验探索.动力学试验结果的分析。更多还原

【Abstract】 The temperature is around 1400℃;the hydrogen reduction rate constant is calculated under the 0.93-1.03 g-Fe/cm~2 min.Comparing with the solid carbon,the reduction rate of hydrogen is more fast;To avoid excessive foaming slag,raw materials should be the use of prereduced ore.Bottom-blowing hydrogen through smelting reduction pilot is researched for understanding the bottom-blowing case,the safety of hydrogen and process operating parameters are useful for future large-scale process-oriented experiments and the theoretical calculations provide the basis of experience.This article focuses on the exploration of hydrogen metallurgy experiments, kinetic analysis of test results.更多还原
