中文摘要：
通过振荡杯高温熔体黏度仪对含Ti铁液的黏度进行测定,研究在冷却过程中Ti、Si对铁液黏度、黏流活化能、凝固温度以及凝固速度的影响.发现含Ti铁液在发生凝固以前,其黏度差别不大,黏流活化能为37.07～44.03 kJ.mol 1.Ti含量对铁液的凝固温度和凝固速度影响较大,Ti含量高的铁液开始凝固温度较高,而且凝固速度更快.硅含量低是钒钛铁液凝固温度低的主要原因.
英文摘要：
The viscosity of molten iron containing titanium was measured with a oscillating cup viscometer at elevated temperatures. The effects of titanium and silicon on the viscosity, viscous activation energy, solidification temperature, and solidification rate of molten iron were studied during the cooling process. It is found that there is little difference in viscosity among molten irons containing different contents of titanium above the solidification temperature, and their viscous activation energies change in the range of 37.07 kJ.mo1-1 to 44.03 kJ.mo1-1. There is great influence upon the solidification temperature and solidification rate by adding titanium into molten iron, and the higher the titanium content, the higher the solidification temperature and solidification rate. Low silicon content is the main reason for low solidification temperature of molten iron containing V and Ti.
