In order to ensure the fluidity of blast furnace slag in Baoshan base, reduce the incorporation amount of blast furnace silica, rationally utilize low-iron and high-silica hematite resources, and reduce the cost of pellet raw material, the method of producing acid pellets with high-ratio low-iron and high-silica hematite is explored, so as to stabilize the blast furnace smelting process and broaden the source of pellets raw material. This method adopts the raw material structure of high-ratio hematite is used to research the effect of w(SiO₂) on the performance of pellets by changing it. The results show that, with the increase of w(SiO₂), it is beneficial to improve the falling strength of the fresh pellet, but the bursting temperature is decreased. Appropriately increasing w(SiO₂) is conducive to the roasting performance, reduction and soft melting performance of pellets, but when it exceeds 7%, the strength of roasted pellets is decreased, and the reduction expansion rate of pellets is higher than 20%. With the increase of w(SiO₂), the degree of interconnection of hematite crystals in the pellet phase is increased, and the frequency of quartz and vitreous occurrence is increased. On the basis of the results of laboratory research, industrial experiments are carried out to produce acidic pellets with w(SiO₂) of 4.0%~6.0% with a raw material structure with a ratio of 50%~80% hematite, and the cost of pellet raw material is significantly reduced.
