中文摘要

在研究硅酸盐熔体和氟化钙基熔渣粘度随温度变化规律的基础上，引入最小曲率半径R_min的概念作为"长渣"和"短渣"的数值判据。R_min值隐含了表征熔体粘度表现活化能E_η，熔化半球点温度T₀和在特征温度T_R的熔体粘度值η_R。以CaF、SiO₂作为典型"短渣"、"长渣"，对所研究的渣系进行分类。不同熔剂或熔渣的R_min计算值对电渣重熔、保护浇铸以及焊接的工艺过程有一定指导意义。

Abstract:

Based on observed η vs T relationships for silicate melts and CaF₂-based slag melts, the R_min is raised to discriminate between long slag and short slag by quoting the mathematical concept of curvature radius. The R_min values of the smallest curvature radius of η vs T plot implicate the apparent activation energy E_η,hemispherical softening point temperature T₀ and viscosity η_R at the character temperature T_R. Using CaF₂ and SiO₂ as reference standard of short slag and long slag respectively, the classification of slags has been made. Calculation of R_min for flux or slag is of significance in ESR, protective casting and welding.
