Abstract

For improving the low flowability, promoting the separation between high Ti-bearing blast furnace slag and hot metal, and replacing CaF2 which would pollute the environment, the influence of B2O3 and CaF2 on apparent viscosity were investigated from 1340°C to 1475°C by SEM, viscometer, et al. The results show that B2O3 has a similar effect to the CaF2 and can decrease the apparent viscosity of high Ti-bearing blast furnace slag. When the amount of B2O3 and CaF2 is equal to 1%, the B2O3 to CaF2 is 1:1. With increasing the B2O3 from 0 to 3%, the perovskite content gradually decreases, titaniferous augite increase, and the Ti(C, N) is almost constant.For improving the low flowability, promoting the separation between high Ti-bearing blast furnace slag and hot metal, and replacing CaF2 which would pollute the environment, the influence of B2O3 and CaF2 on apparent viscosity were investigated from 1340°C to 1475°C by SEM, viscometer, et al.
