Abstract: 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 ℃ 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 ℃ for 20 minutes, the mass fraction of TiC 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.
