Experiments were carried out in the lab to simulate dropping zone of blast furnace by a high temperature oven,and the effect of Al2O3 on charge softening temperature range,melting temperature range,maximum pressure and other high temperature physical properties had been investigated.The results showed that with the increase of Al2O3 charge,both start softening temperature(T10) and the end softening temperature(T40) increased,but softening interval(ΔT1) was narrowed; charge renewed pressure temperature(Ts) were decreased but dropping temperature(Td) were increased,while melting range(ΔTds) was widened; the maximum pressure(ΔPmax) and the total characteristic droplet value(S) were also increased,which resulted in worse droplet performance.It can be concluded that increase of Al2O3 produce negative effect on the performance of the droplet.
