【摘要】：对Fe-Ti-N-C-O系热力学计算和分析表明,钒钛铁精矿盐酸浸出渣采用碳热还原工艺制备TiCN在热力学上是可行的。通过XRD对还原产物进行物相分析和计算,探索了配碳量、还原温度和还原时间对还原过程和还原产物中TiC_(1-x)N_x的C/N的影响,试验结果表明:随着还原温度的升高、还原时间的延长和配碳量的增加,还原产物中TiC_(1-x)N_x的C/N值有下降趋势。在配碳量为1.6,还原温度1500℃,还原时间30,min时,还原产物TiC_(1-x)N_x的x值为0.775,C/N=0.29。
[Abstract]:The thermodynamic calculation and analysis of Fe-Ti-N-C-O system show that the preparation of TiCN by hydrochloric acid leaching slag of vanadium titanium-iron concentrate by carbothermal reduction is feasible in thermodynamics. The effects of carbon content, reduction temperature and reduction time on the C / N ratio of TiC_ (1-x) N _ x in TiC_ (1-x) N _ x were investigated by XRD. The results show that the C / N value of TiC_ (1-x) N _ x in TiC_ (1-x) N _ x decreases with the increase of reduction temperature, reduction time and carbon content. When the carbon content is 1.6, the reduction temperature is 1500 鈩，
