美国马萨诸塞州的麻省理工学院材料工程系进行了该项研究。试验是在 172 3K温度下 ,用 Fe—C熔滴还原 Ca O— Si O2 —Al2 O3渣中的 Fe O,考察它的还原率。试验时 ,将 2 g重 Fe— C熔滴滴到数量比其大得多的上述熔融渣中 ,熔滴中碳与渣中的 Fe O发生还原反应 ,析出 CO气体 ,通 Massachusetts Massachusetts Institute of Technology Materials Engineering conducted the study. The experiment is to reduce FeO in CaO-SiO2-Al2O3 slag with Fe-C droplet at a temperature of 172K, and investigate its reduction rate. During the test, 2 g of heavy Fe-C melt was dropped into the above molten slag with a much larger amount, and the carbon in the droplet was reduced with FeO in the slag to precipitate CO gas.
