To ensure smooth production and operation of the first homemade production line of belt type roasting machine pellets in Fujian Sangang, such effects as ore blending structure, mass fraction of MgO, proportion of coking dust and thermal conditions are systematically investigated, based on such existing raw materials as two domestic magnetite concentrates (MK and XNK), and two imported magnetite concentrates (AMC and UMC), while pilot tests are also conducted. The results show that ore blending scheme of 75% MK + 25% XNK or 50% MK + 25% XNK + 25% AMC exhibits better performance, and high pressure grinding rollers pretreatment needs to be applied. Moreover, the MgO content of fired pellets is better to be less than 2.0% while the addition of coking dust is not recommended. Under optimal conditions, the oxidized pellets possess good cold state strength and high-temperature metallurgical performance, which can meet the requirement of large-scale blast furnace.
