| 摘 要： | 利用现场生产用原料配置保护渣基样,分别以B_2O_3、TiO_2作为CaF_2的替代物,测定了不同含量CaF_2、TiO_2、B_2O_3保护渣的黏度和转折温度,绘制了相应的lnη-1/T曲线图,并进行拟合计算得到了其黏流活化能。深入分析了保护渣中CaF_2、TiO_2、B_2O_3含量的变化趋势及对保护渣流变特性影响的内在原因,得出了适宜流变特性的无氟保护渣中合理的TiO_2、B_2O_3含量,保护渣内的TiO_2含量不超过9%,B_2O_3含量不超过7%。

| Abstract: | In this paper the transition temperature and viscosity of mould powder with different B2O3,TiO2 and CaF2 had been measured,and the corresponding lnη-1 / T curve had been plotted.Viscous flow activation energy had been calculated through fitting method.The effect of CaF2,TiO2 and B2O3 contents on the rheology characteristics of mould powder had been investigated.The reasonable TiO2 and B2O3 contents for appropriate rheological properties of mould powder without fluorine are less than 9％ and 7％,respectively. |
