摘要
通过热力学计算表明,在常压下难以进行的高碳锰铁固态脱碳,真空下可以实现。将高碳氧化锰与高碳锰铁混合,置于管式炉内高温处理,并抽真空,通过温度调节,一定时间后取出产物测定碳含量,并分析影响脱碳反应的因素。试验结果表明:延长反应时间及提高团块紧实度能够显著促进反应的进行,反应物中高碳氧化锰的比例及其反应温度与脱碳反应有一定关系。
According to the thermodynamic calculation,it＇s difficult for decarbonization in solid-state of high-carbon ferromanganese at normal pressure,but it can achieve in vacuum.To put high-carbon ferromanganese oxide mixed with high-carbon ferromanganese in tube furnace of high temperature,then evacuating,adjusting the temperature.Removing the product after a certain time and determining the carbon content,and analyzing the factors that affect the decarburizing reaction. The experimental results show that extending the reaction time and improving the compaction of agglomerate can significantly promote the reaction;the ratio and the reaction temperature of high-carbon ferromanganese oxide in the reactant have close relationship with the decarburizing reaction.
