【摘要】：對(duì)Fe-Ti-N-C-O系熱力學(xué)計(jì)算和分析表明,釩鈦鐵精礦鹽酸浸出渣采用碳熱還原工藝制備TiCN在熱力學(xué)上是可行的。通過(guò)XRD對(duì)還原產(chǎn)物進(jìn)行物相分析和計(jì)算,探索了配碳量、還原溫度和還原時(shí)間對(duì)還原過(guò)程和還原產(chǎn)物中TiC_(1-x)N_x的C/N的影響,試驗(yàn)結(jié)果表明:隨著還原溫度的升高、還原時(shí)間的延長(zhǎng)和配碳量的增加,還原產(chǎn)物中TiC_(1-x)N_x的C/N值有下降趨勢(shì)。在配碳量為1.6,還原溫度1500℃,還原時(shí)間30,min時(shí),還原產(chǎn)物TiC_(1-x)N_x的x值為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，
