Abstract：In order to reduce the hot metal cost and in responding to shortage of iron ore resources, Rizhao Steel used low basicity sinter to replace part of acid burden. By optimizing the charge mixture, adjusting the moisture, controlling the process parameters of sinter machine and equipment modification, low basicity sinter had better technical indexes. Low basicity sinter is mainly bonded by silicate, it has lower strength and RDI compared to high basicity sinter and similar reducibility as lump ore. Using the low basicity sinter (9%-33%), the blast furnace had no trouble reaction, and kept smooth and stable operation. When the low basicity sinter proportion is 20%, the cost of 12.65 Yuan RMB per ton of iron was reduced.
