摘    要：针对含钛铁水容易变粘稠的特点,在实验室中研究了不同[Si]、[Ti]含量变化对铁水粘度,熔化性温度以及流动性能的影响;结合热力学计算分析了钛在铁水中溶解度同温度变化的关系。结果表明:铁水变稠主要受钛的溶解和析出影响,[Si]对钛溶解具有消弱作用,铁水中∑[Si+Ti]为0.6%左右,含钛量在0.29%以下时,钛对铁水的粘度影响较小,适宜炉温的选择是防止含钛铁水变稠,铁水粘罐,渣铁难以分离等的关键。

Abstract: In allusion to the features that hot metal bearing Ti is easy to become viscous,the impact of , content on viscosity,melting temperature,and flow properties of hot metal was studied in the lab..Relationship between the solubility of titanium in molten iron and the temperature changes was calculated and analyzed which combined with thermodynamic.The results show that molten iron become viscous which mainly affected by the dissolution and precipitation effects of titanium. has a weakening effect on the dissolution of titanium.Titanium has little effect on the viscosity of hot metal when Σ about 0.6 % and below 0.29%.The choice of appropriate blast furnace temperature is the crux of preventing that hot metal containing titanium became viscous,hot metal sticks pot,slag iron is difficult separation and so on.
