| Abstract |
Using high frequency induction furnace, the reaction of pig iron and Ti-ore was carried out at temperatures between 1450 and 1600℃. After 40 minuters reaction, samples of molten pig iron and slag were taken and their chemical compositions were analyzed. The ratio of TiO₂(in slag)/TiO₂(in ore) and desiliconization of pig iron were investigated in relation to the amount of Ti-ore, temperature and type of crucible. The concentration of TiO₂ in slag and the desiliconization of pig iron were increased with increasing Ti-ore content and decreasing temperature. The ratio of TiO₂(in slag)/TiO₂(in ore) was 2.6∼2.8 in magnesia crucible and 3.5∼5.6 in graphite crucible. The desiliconization of pig iron became better in magnesia crucible than in graphite crucible. The desulfurization and dephosphorization effects were not observed. |
