| 摘 要： | 对脱碳物料进行碳含量测定并采用电子探针及X线衍射(XRD)进行显微结构和物相分析。研究结果表明:在实验件下,高碳锰铁粉的碳含量由6.61%分别降至1.54%,1.13%,1.05%,0.94%;脱碳物料的显微结构主要为包裹与镶嵌结构、球形层状结构和实心球形结构,物相组成主要为金属锰、金属锰铁、低碳锰铁碳化物和氧化钙。脱碳温度在900℃时的综合脱碳效果最好,脱碳物料的氧化程度低且无锰酸钙等成分。

| Abstract: | The carbon content of the materials after decarburization was measured and the materials were analysed using electron microprobe and X-ray diffraction(XRD).The results show that under experiment conditions,the carbon contents of high-carbon ferromanganese powder are reduced to 1.54%,1.13%,1.05% and 0.94% from 6.61%,respectively.The microstructure of decarburization material is mainly enclosing structure,mosaic structure,spherical-layered structure and spherical structure;phase composition is mainly composed by manganese,ferromanganese,low-carbon ferromanganese and calcium oxide.The best overall decarburization effect is achieved when the decarburization temperature is 900 ℃,and the oxidation degree of decarburized materials is on a low level and without manganese calcium and other ingredients. |
