中文摘要：

以热力学计算为依据,研究在焦炭还原攀钢含钛高炉渣的过程中,反应温度和保温时间对碳化钛的生成量的影响,同时利用超重力技术来分离还原产生的碳化钛.研究结果表明：含钛高炉渣经高温碳热还原后得到有价组元碳化钛,当实验温度设定在1 600°C保温5 h时,还原渣中碳化钛的含量最高,熔渣中钛氧化物转化为碳化钛的转化率达到最佳.另外,还原渣经超重力分离后碳化钛被截留在碳毡上部的精矿中,脉石相则被分离到下部坩埚中,还原渣在重力系数G=300于1 320°C等温分离20 min后,精矿中碳化钛的含量由还原渣中的12.1%提高到26%,通过超重力技术可以使碳化钛含量提高一倍多.

英文摘要：

Based on thermodynamic principle,the reaction carried out by coke on the high temperature according to titanium-bearing blast furnace slag in PZH steel was investigated,and the reaction temperature and holding time was considered for the production of TiC.The results show that the valued phase TiC is obtained from titanium-bearing blast furnace of PZH steel after carbonized at high temperature.The mass fraction of TiC gets the most in the carbonized slag and the conversion rate of titanium oxide is the best when the experimental condition is set at 1 600 °C for 5 hours.In addition,TiC phase is intercepted on the carbon fiber felt and the gangue phase is separated to the bottom of the crucible by super gravity filtration method.After separation at the gravity coefficient of G=300 and T=1 320 °C for 20 minutes,the mass fraction of Ti C in the concentrate increases from 12.1 % of normal slag to 26 %,therefore,the mass fraction of TiC can achieve more than twice through super gravity.
