Analyzed the effects of protection of titanium-bearing pellet ore on the parameters of blast furnace production. During the protection of titanium-bearing pellet ore, the amount of titanium in the slag and melted iron ascended, the viscosity of melted iron increased and mechancial scouring action decreased, fuel rate went up 6.7 kg/t, thermal load in the hearth steadily declined and effectively protected the hearth. Owing to the amount of titanium in the slag and melted iron ascending and viscosity increasing, the interval time of tapping melted iron delayed about 18 minutes, hearth sidewall temperature obviously decreased. The protection effect of titanium-bearing pellet ore was remarkable.
