Abstract

Effects of adding SiO2 or Al2O3 as additives on the viscosity and on the surface tension of calcium ferrite melts. CaO Fe2O3 (CF) and CaO 2Fe2O 3(CF2), have teen examined and the effects of SiO 2 and Al2O3 addition on the melt formation rate in calcium ferrite system were also investigated. The viscosity of calcium ferrite melts was increased, and the surface tension of calcium ferrite melts was decreased with, increase the contents of SiO2 or Al 2O3. At the same content of additive oxide, the addition of Al2O3 was more effective for increasing the viscosity than the addition of SiO2. On the contrary, the addition of SiO 2 was more effective for decreasing the surface tension than the addition of Al2O3. The effect of SiO2 addition on the formation rate of molten calcium ferrite was affected that it added to CF rather than CF2. The effect of Al2O3 addition on the formation rate of molten calcium ferrite was affected that it added to CF rather than CF2. The softening and melting rates of sample in CF system were also larger than that of sample in CF2 system.
