Effect of Pulse Electric Field on Reduction Characteristics of Ferromanganese Oxide

本实验以常温常压条件下锰铁氧化物还原、凝固的研究为基础,推广到外场(脉冲电场)作用下锰铁氧化物还原规律的研究,用不同脉冲电场电压处理锰铁氧化物熔体,促进C的还原反应,用Im ageJ软件统计锰的晶粒尺寸和各个面积区间锰的晶粒个数,得到脉冲电场能促进锰铁氧化物二次还原,且与电场电压和锰铁氧化物的组成有关,电场处理的二次反应析出颗粒尺寸分别为3.383μm、4.332μm、3.224μm、4.356μm,还原锰的面积含量分别为6.2%、5.5%、6.4%、5.1%。

The experiment has been based on the reduction of ferromanganese oxide and solidification of metal with the condition of normal temperature, the rule of reduction of ferromanganese oxide with carbon has been extended to outfield （such as pulse electric field）, the reaction between ferromanganese oxide and carbon was improved by different pulse electric field voltage ,the grain dimension of Mn and the quantitate of Mn in different proportion region were Stated by ImageJ software. We come to conclusions that pulse electric field can accelerate secondary reduction of ferromanganese oxide,its effect is in relation to pulse electric field voltage and the constitute of ferromanganese oxide. The grain dimension of secondary reduction is： 3. 383 μm、4. 332 μm、 3. 224 μm、 4. 356 μm and the different area of reduced manganese is： 6.2 % 5.5 %, 6.40%, 5.1 %, respectlvely.
