摘      要：The effect of SiO_(2) and B_(2)O_(3) on viscosity and surface tension of CaF_(2)-CaO-Al_(2)O_(3)-MgO-SiO_(2)-B_(2)O_(3) slag designed for electroslag remelting of rotor steel was *** viscosity of the slag melts increases with increasing the SiO_(2) content from 0.37 to 8.03 mass%,and the viscous activation energy increases from 54.21 to 58.49 kJ/*** B_(2)O_(3) content of the slag from 0 to 3.62 mass%exhibits a similar effect on the viscosity,and the activation energy increases from 47.30 to 55.71 kJ/*** increase in the viscosity and activation energy for viscous flow of slag is attributed to the enhanced polymerization degree of slag melts network with increasing either SiO_(2) or B_(2)O_(3) *** surface tension of slag melts decreases with increasing *** surface tension of slag melts decreases with increasing either SiO_(2) or B_(2)O_(3) content,which is originated from the increase in the polymerization degree and the decrease in the CaO content of the slag.
