WhatsApp: +86 18838072829The iron ore in the sintering dust was mainly magnetite, a small amount of hematite and gangue. Moreover, a small amount of quicklime also existed in the sintering dust due to using it as a solvent for the sintering process (Wu et al., 2022b). The peak intensity of metallic iron rose with the temperature, while peaks of magnetite and hematite ...

WhatsApp: +86 18838072829The basic hightemperature properties of iron ore play a crucial role in optimizing sintering and ore blending, but the testing process for these properties is complex and has significant lag time, which cannot meet the actual needs of ore blending. A prediction model for the basic hightemperature properties of iron ore fines was thus proposed based on a combination of machine learning ...

WhatsApp: +86 18838072829The sinter plant that converts the iron ore fines into a desirable blast furnace feed, offers an avenue for recycling wastes. One of the several wastes that are produced at an iron and steel plant is the undersized pellet fines, which cannot be directly used in iron making. The present study evaluated the influence of these pellet fines on the sintering process. 5 experiments were conducted ...
